How To Ensure The Machining Process Efficiency Of Precision Parts | JTR

High precision components used in various industries of testing equipment – scientific instruments, mainly used in domestic scientific instruments. In the instrument industry, precision components factory provides parts processing, need to consider the corresponding technology and efficiency, as well as detailed process. So how to ensure the factory processing efficiency of precision parts and how to do precision parts processing well? Let’s take a look at the following guide.



How To Ensure Machining Efficiency Of Precision Parts
1. Laborious, rough finisher to ensure machining accuracy. The characteristics of rough machining and finish machining are different. For example, in rough machining, the workload will be relatively large, such as cutting and clamping force. Therefore, finish machining and finish machining should be carried out separately, and the processing conditions should be strictly controlled.

2. Select appropriate processing equipment. For finishing and rough machining, they have different requirements for equipment. In the rough machining process, we can choose high-precision machine tools, but in finishing, we need to choose high-performance machine tools.

3. Do precision parts processing heat treatment steps. The implementation of this process has a high impact on the processing quality, which must be paid attention to.

But with the right to enter the scientific method of precision parts processing work to meet the growing demand of enterprises, will strive to improve. So, how to do a good job in precision parts processing?



1. Choose the equipment reasonably

Rough machining of mechanical parts is mainly to cut off most of the machining allowance, and it does not need high-precision machining of mechanical parts, so rough machining should be high-power and high-precision machine tools. In the process of completion, adhere to the use of relatively high-precision machine tools.. rough, completed on different machines, can give full play to the equipment capacity, and can extend the service life of precision machine tools. You can totally be free to choose  JTR CNC machining service, they are professional in this field, with decades of working experience to support you the best service and advice.

2. In order to ensure the machining accuracy of precision parts, the coarse and fine mechanical parts are processed well respectively

Because when rough machine parts, cutting quantity, cutting force of workpiece, clamping force, heat, surface hardening of mechanical parts, significant, large internal stress in the workpiece, if rough, rough processing is completed continuously, the mechanical parts after precision will soon lose stress redistribution. It is used for machining some mechanical parts with high precision. Roughing and finishing, or aging treatment should be arranged after low temperature annealing to eliminate internal stress.

3. Heat treatment is often arranged in the process of precision parts processing

Location is as follows: Heat treatment to improve metal cutting performance, such as annealing, normalizing, tempering, set in the treatment of general mechanical parts. In order to improve the mechanical properties of the parts, such as carburizing, quenching and tempering, the mechanical parts are generally set in the above treatment. If the deformation is large after heat treatment, the process after processing should be arranged.

For some equipment produced by many machinery factories, the relationship between more precision parts will be used. When so many people will find out whether some machine parts want to be used well enough, sometimes even some bad phenomena will appear. It is necessary to use a good technology at this time, that is precision parts processing, precision parts processing. So what’s the concept, Some precision parts that have been formed can be processed well and completely, for example, some of them meet your requirements, so you don’t really need good parts inside the machine. As long as you process your parts and tell them that what you need is part of the polite words, you
can get the parts you want to meet in the machine.

Use Your Differential Lock In Right Way

A differential lock (diff lock) https://www.tre4x4.com/single/air-locking-differential.html can offer your 4x4 a boost when it is caught in a tricky off road situation. It's necessary to know how and when to use your differential lock to easily cross difficult terrain and get the most benefit from your differential lock. 


What is Diff Lock?
The four wheels on your 4X4 need to run at different speeds and angles to efficiently turn fast corners. Both the front and rear axles have the differential. This differential will direct power to the wheel that is easiest to rotate – providing necessary power to each wheel in different driving situation. A differential lock secures this differential in place, making all the wheels move as one at the same speed. This pushes equal power to all wheels, which is necessary when handling difficult terrain.


When should you use diff-locks?
There are many off-road situations where you will need to engage the differential lock. There are no hard or specific rules to follow for using your differential lock, but here are some guidelines for you to follow:

[b]Toyota Corolla Problems – What Year Is Safe To Buy?[b]

March, 26, 2021

The Toyota Corolla is a line of subcompact and compact cars that have been produced and manufactured by Toyota and was first introduced in 1966. Back in the day, the Corolla was the best-selling car worldwide, with the car model earning the best-selling nameplate in the world in 1997. 20 years later, Toyota has reached an impressive milestone of 44 million Corollas sold over 12 generations.

Earlier models featured rear-wheel-drive cars, while the more modern and recent models have been front-wheel drive. Four-wheel drive versions are also an option and have been produced throughout the generations, unbecoming direct rivals to the competition like the Nissan Sunny and the Honda Civic.

We start rating the Toyota Corolla with the ninth generation which started in August 2000, with the new generation coming out in mid-20001 with a fresh look and called the Corolla Altis. After the ninth generation, the tenth generation was introduced in 2006, and was called the Corolla Axio in the Japanese markets.

The eleventh generation was produced starting in May 2012, with the new option now available in either a 1.3-liter or 1.5 four-cylinder engine, and either in front or all wheel drive. The last generation we will discuss is the twelfth generation, which has been produced since 2018 and debuted at the Geneva Motor Show.

[b]Toyota Corolla Common Problems:[b]

Before we go through the problems of Corolla year by year, we are going to do a general overview of the main problems in each category or generation of Corolla produced. By narrowing down the problems by generation, you can figure out the most common issues and how to fix the problems you might run into as a new car owner. Out of all of the generations, the more modern and latest generations have the fewest problems and have the most minor issues.

[b]1: 2000-2005 Generation:[b]

Worn Piston Rings – one of the main problems of the Corolla is worn piston rings, which can lead to excessive oil consumption and possible engine failure, which can be quite expensive. Symptoms of worn piston rings include oil sludge buildup and low oil levels.

Airbag Control Module Failure – Regarding the 2003-2004 Corolla, the owners of these cars have had their front and side airbags deploy unexpectedly and not during intended use. The issues of the airbags related to the circuits in the cars short-circuiting from excessive noise, causing the airbags to deploy randomly.

[b]2: 2002 Toyota Corolla Problems:[b]

The Toyota Corolla had more problems listed than the previous eras, with the beginning generation having very few issues, and the problems really starting to crop up after the 2000 model year. The main category of concern for the 2002 year is the engine, with the seatbelts and airbags category also having a high amount of NHTSA complaints.

Regarding the engine issues, the users complained the most about the engine using excessive oil, the engine failing, the tapping noise coming from the engine, and the buzzing noise occurring on acceleration. To fix the engine using excessive oil, the typical repair cost comes in at about $2,600 and occurs at around 97,000 miles.

[b]3: 2003 Toyota Corolla Problems:[b]

The main category of concern for the 2003 year Corolla is the transmission, with the users having the most complaints regarding this system and the most NHTSA complaints about the seatbelts and airbags. Owners have the biggest issues regarding transmission failure, the transmission and differential failure, the noisy transaxle at the transmission and grinding noise occurring. The price to fix the failing transmission is around $2,830 and occurs at around 116,000 miles.

The NHTSA lodged over 300 complaints regarding the seat belts and airbags category, with these issues resulting in 42 crashes, 44 injuries, and occurring at an average of around 72,000 miles. Users state that the airbag warning indicator remains illuminated, the car airbags do not deploy during a crash, and the airbag light turns on and off while driving.

[b]4: 2004 Toyota Corolla Problems:[b]

Regarding the following year of the Corolla, the engine is the highest problem category, followed by the interior accessories. Users have stated that the engine problems are most frequent regarding the ticking noise from under the engine, sludge building up over time, clicking noise coming from under the hood, the engine not slowing down while braking, the engine light coming on, the engine light stalling while driving, excessive oil consumption, and the stuck starter pinion.

The interior accessories concerns focus on the broken door lock actuators, the center console door hinge breaking off, the rearview mirror and visor colliding, and the spring and hinge on the storage compartment breaking over time.

The 2005 and 2006 years of vehicles also have the same amount of problems listed from users, with the main categories of concern dealing with body and paint in the 2005 year, and the engine category in the 2006 model year. For the earlier model, the body and paint problems focus on the paint peeling, the water leaking into the interior, the paint peeling behind the rear wheels, and the trunk not being able to open. To fix any of these paint issues, the typical repair cost is around $540 and occurs at around 115,000 miles.

[b]6: 2006-2011 Generation:[b]

Premature Passenger Airbag Failure – when the passenger airbag goes off during a potential crash, there is a possibility that the airbag could rupture and cause metal fragments to hurt the occupants. This is due to the propellant degrading over time due to unstable temperatures and very high humidity levels.

Cracked Engine Control Module – the circuit board inside the engine control module in this generation of Corollas is more susceptible to cracks, causing harsh transmission shifting or the engine failing to start.

[b]2006 Toyota Corolla Problems[b]

For the 2006 model year, the engine problems had the highest amount of user complaints. The top reports of owner issues focus on the engine surging while stopped, the car cutting off while driving, the sudden unintended acceleration, the engine stalling out while driving, the engine failing, the car having a low idle, and the check engine light coming on.

[b]7: 2009 Toyota Corolla Problems:[b]

After two years of relatively few problems, the 2009 model year had the highest number of user and NHTSA complaints, with the most user complaints focusing on the engine, and the NHTSA lodging 555 complaints regarding the seatbelts and airbag system. Regarding the engine concerns, users have cited excessive oil consumption, loud noises from the engine, check engine light turning on, the car surging, the car not being able to start, the sudden power loss, and the car’s accelerator getting stuck. To fix the excessive oil consumption, the total repair cost is around $4,570 and occurs at around 100,000 miles.

The NHTSA complaints about the seat belts and airbags mainly focus on the frontal airbags, the side and window air bags, the rear seat belts, and the buckle assembly. These issues have caused 48 crashers, 1 fire, 40 injuries, 1 death, and occur at around 16,000 miles.

[b]8: 2010 Toyota Corolla Problems:[b]

After the worst year on record, the 2009 Corolla, the 2010 model year had very high NHTSA complaints for two categories – the steering system and the seatbelts and airbags. The highest number of user complaints focused on the body and paint area of the car.

The complaints focusing on the steering system focused on the car clunking while turning, the steering being stiff, the car pulling to one side, and the steering being loose. These steering issues have resulted in 18 crashes, 13 injuries, and occur at around 14,000 miles ,with users stating that the steering wheel can fail and is unable to turn to either side.

The concerns regarding the seatbelts and airbags focus on the airbag recall, the airbags not deploying, and the seat belts and air bags not working correctly in an accident. The air bag issues in the 2011 Corolla have resulted in 41 crashes, 35 injuries, and occur at around 15,000 miles, with users stating that the airbags didn't go off in the occasion of an accident.

[b]9: 2012-2015 Generation:[b]

Overly sensitive Electric Power Steering System – Many cars in this specific generation come with an overly sensitive electric power steering system causing the steering wheel to drift to the side without the proper driver input, with these issues having a wheel alignment issue.

[b]2012-2013 Toyota Corolla Problems[b]

During the next few years, the problems in the Corolla drop dramatically, with the three years having very few NHTSA and user issues in any category. The main areas of concern in the 2012 had issues with the brakes, and the 2013 had concerns regarding the interior accessories.

The 2012 Corolla brakes problems focus on the brakes squeaking, brakes vibrating, and the brake pedal going to the floor when trying to stop the car. The 2013 Corolla has user complaints regarding the interior accessories like the radio turning off several times while driving, the broken dash mounts for the cabin filter, the dashboard melting, the rattling occurring around the steering wheel, and the seats being uncomfortable over time.

[b]Cruise Control[b] – The most common problem with the 2018 and 2019 Corolla involve the cruise control feature. When coasting on a highway, the transmission downshifts, but in this model, the throttle is not restricted enough, so it causes the car to accelerate slightly.

[b]Toyota Corolla Reliability:[b]

The 2020 Toyota Corolla reliability depends on the pros and cons of this car – unfortunately, the Corolla finishes in the bottom half of the compact car rankings despite a great predicted reliability rating, due to the lack of performance and cabin space. The pros of the Toyota Corolla are the class-leading reliability rating, the great fuel economy and miles per gallon, and the active safety features. The cons of this Corolla feature a sluggish and lackluster engine base, the inconsistent transmission performance, and the cramped rear seat for long drives.

Despite these negatives and Toyota Corolla problems, the car earned a #8 ranking in the Compact Cars category, #10 ranking in the Hatchbacks category, and the #12 ranking in the Small Cars category. Furthermore, it was a finalist in the 2020 Best Compact Car for the Money category.

With the overall rating, the US News Scorecard earned an 8 out of 10, with the critics’ rating earning a 7.5 out of 10, performance averaging 7.1, interior coming out to 7.0, safety equalling 9.8 out of 10, and the JD Power ranking getting an impressive 4.5 out of 5 stars.


TOYOTA COROLLA AND OTHER BRANDS

[b]Toyota Corolla vs. Mazda 3[b]


The Mazda 3, when compared to the Corolla, is a stronger and more performance oriented option than the Corolla. The Mazda’s engine is strong, agile, quick, and handles smoothly and engages quickly. In addition to the performance, the interior is upscale and luxurious. Both of these cars are available as sedans or hatchbacks, but neither one wins out in the passenger room category. The pro of choosing the Corolla is the driver assistance features and the better predicted reliability rating.

[b]Toyota Corolla vs. Honda Civic[b]


The Honda Civic is a well-rounded compact car that just beats out the Toyota Corolla. The Civic comes in various options, like the sedan, the coupe, and the hatchback body styles, giving you a choice of body style and engines for you to sue. The Corolla has a standard entertainment and infotainment system, while the Civic’s is optional and costs some more money.

However, some may argue that the Honda provides a more interesting and fun car to drive when compared to the Corolla. In addition, the Civic serves more interior space in the backseat and has a nicer and more luxurious interior, providing a more upscale look.

Why is The Portal Axle Necessary For Off-road Vehicles?

The portal axle(https://href.li/?https://www.tre4x4.com/single/portal-axle.html
) is a component for off-road vehicles that allows greater ground clearance between the vehicle's landing gear and any obstacles that the vehicle must pass through.


Hold part or all of the weight
In many cases, the portal axle connects the two wheels together, and it is usually responsible for carrying part or all of the weight of the vehicle. Most portal axles are aligned with the center of the wheel, but the portal axle is raised higher than the center of the wheel, allowing for better ground clearance. The hubs at both ends of the portal axle will contain gears that help drive the wheels.

Change the center of gravity
The gears at both ends of the portal axle also reduce the torque on the hub and portal axle assembly, which means that the housing can be smaller and thinner. This means that the entire portal axle assembly can be lighter, which helps to improve the center of gravity of the vehicle. However, the problem with installing gears in these locations is that they may overheat after prolonged use, and overheating may cause internal components to fail. This is an important consideration because portal axles are commonly used in military vehicles or other vehicles that operate in harsh terrain or harsh conditions.


Short the distance between the vehicles body and the ground
Sometimes buses and other vehicles are also equipped with portal axles, albeit in a significantly different configuration. For off-road vehicles, the portal axle is located above the center of the wheel; on a bus, the portal axle will be located below the center of the wheel, effectively lowering the vehicle body to the ground. This is usually done to make it easier for passengers to enter the bus entrance; a lower entrance is easier for people who cannot climb the stairs well or cannot safely climb the stairs.

Designed for specific vehicles
One obvious disadvantage of a portal axle is the cost. The cost of the components is often higher than a standard axle, and installation on some vehicles may be difficult or impossible. Most vehicles with such components are specifically designed to accept them, and they may already have axles installed. Conversion kits do exist, but they can be difficult to install. The designer of the vehicle will need to take into account the extra weight of the wheel hub, and the steering and stabilizing elements will need to be overbuilt to compensate for the added weight. Therefore, this portal axle is generally used in specific vehicles such as military vehicles, so for these specific vehicles, portal axles are indispensable.
In general, portal axles are very essential for certain vehicles, such as military vehicles, buses, and off-road vehicles. 


TRE 4x4 Productions is specialized in off-road vehicles parts such as portal axles. The technicians at TRE 4x4 are continually conducting research and development to create new products to meet the demands of the off-road community.

 

Using a winch or snatch strap involves massive forces: failure could be deadly. The safest bet is to simply drive out of a situation that’s got you stuck—no other vehicle is necessary. That's where a TRE recovery board comes in.

The nylon recovery boards also double as shovels: if you can’t place them under your tires and drive out, you can use them to excavate your wheels. Or just use them to dig a fire pit or latrine in your new base camp. And you don’t need to be driving a 4x4 or going off-road to benefit from them. They work just as well in the snow and on the road as they do in mud or soft sand off of it.

How to choose a portal fridge for your car?

Today, we are here to help you choose a suitable portable fridge（https://www.tre4x4.com/product/4x4-fridges.html
） for you by answering some consumers' questions.

1.  What liter do I need for my car?
A large fridge is better for you to store more foods or drinks. But it will cost more energy and take much space of your car. You need to consider your usage habits, do you want to remove the fridge from the car? Could you bear to climb up and down to pick up the beers from the fridge? So the car’s space is also an important point for you to choose the fridge, you must consider if the portable fridge could be put in your car.
Then you need to consider the capacity of the portable fridge.
Here is the detail of our portable fridge:
35L: fits for one weekend trip.
45L & 55L: a common model for a long weekend trip.
68L & 78L & 96L: for a whole family or a team. need to consider if the space of your car is big enough for it.
 
2.  What function do I need of the portable fridge?
Do you only want a fridge conservatory or also want to have a freezer? The freezer need could make you pass a lot of choices. For some fridges, it could only keep the food fresh. But some portable fridges, have dual compartments, such as the TRE Ice-Rhino fridge freezer. The fridge has two storage parts, you could set the temperature separately, it could meet your different needs. 
 

3.  Compare the cost and the feature of a portable fridge. 



Compressor type
The compressor is the heart of the fridge, so choosing a fridge with a good one should keep you in business for many years. Recommended compressor brand: SECOP (Danfoss), Sawa, Fuji, or Waeco.

Baskets
Check if the baskets are removable. One removable basket could help you get the foods or drinks from the fridge easily, and it is easy to clean.
Control panel
Check how difficult the control panel is to set and adjust the temperature.
The use environment
The compressor could not only be used in your car but also could be used in your house directly, The Plug should be the same as your fit for your house’s socket.

Do I really need a winch？ We believe the answer is a yes.

A winch is a life-saver and should be equipped as early as possible, along with a reliable recovery kit. We recommend TED Winchhttps://www.tre4x4.com/single/4x4-recovery-kits-accessories.html which is reliable and reputable. TRE4x4 synthetic rope is a good choice for winches because it’s more wear-resistant, it’s lighter, doesn’t store as much potential energy under load (preventing snapping), and the synthetic rope doesn’t develop sharp burrs like a steel rope.
Along with the winch, don’t forget to bring some shackles, you can keep at least one connection to the front and back of the truck at all times, for ease of use, less to fiddle with in a recovery situation. TRE soft shackles are an additional option as well.
A winch line dampener will prevent a major incident given a malfunction with the winch (strap or cable snapping).
 

Recovery Kit

 

You should take vehicle recovery seriously. Not just because the items pictured here will save the day, but because the massive forces involved also make it dangerous.  Inspect your recovery kit regularly for wear and damage, as well as choosing quality recovery equipment, TRE recovery kit is a great choice that has been proved by thousands of users in 50 counties in the world.
