Polishing technology is widely used in precision machining field, It’s very important processing that no matter for precision machined parts or Mold Parts. With the wide application of hardware products, the appearance quality requirements for hardware is becoming more and more higher, then the requirements for surface polishing will also be higher, and the roughness requirements for mirrored and highlighted surface products is especially higher, so the requirements for polishing also becoming higher and higher. Polising Not only increases the beauty of the precision machined parts, but also can improve the Corrosion and wear resistance of the material surface for precision machining parts, it also Convenient to Injection molding processing such as making plastic products easy to demold, reduce the production of injection cycle etc.
A:Rough polishing and grinding: The surface was normally rough after processing of Lathe, Grinding, CNC, cutting or EDM, It need be polished by using oilstone, Use kerosene as the lubricant,the General order of use will be #180 ~ #240 ~ #320 ~ #400 ~ #600 ~ #800~ #1000.
Whetstone polishing is very important and difficult processing, According to the different specifications of processed products like automotive parts, Cross lapping was performed equably at an Angle of about 70 degrees, The optimal round trip range is about 40 ~ 70 mm. Whetstore processing will also be changed according to the material for machined parts, In order to save the time, they will choose #400 to start.
B: Normal Polishing mainly use sandpaper and kerosene.After Whetstone processing will be sanding paper, When sanding paper, pay attention to the round edges, sharp corners, round corners and orange peel appears. so the process of whestone should be done with high precision. The important point for Sanding paper: Sand paper is intersected with hard sticks for grinding like Whetstone processing , and the grinding frequency of one side of sand paper is about 10 ~ 15 times. If the grinding time is too long, the abrasive force of sand paper will be reduced, and then it will lead the surface finish be uneven( This is one of the reason for orange peel appears). sanding paper usually use bamboo piece to grind, Actually the optimal ways is use the wood bar with less elastic or aluminum bar with Low hardness to grind at a 45 degree angle. The grinding surface should not be rubber or highly elastic materials, it can be grind at Acute Angle if the shape can’t grind at 45 degree angle. The Numbers of sandpaper are #220~ #320~ #400 ~#600~ #800 ~#1000~#1200~#1500. In fact #1500 sandpaper is only suitable for hardened die steel (above 52HRC) and not for prehardened steel as this may cause surface burns to the prehardened steel.
C:Precision polishing mainly use diamond paste. If use polishing wheel that mixes diamond abrasive powder or paste to grinding, The paste and polishing wheel can remove the Grinding crack that remained by #1200 and # 1500 sand paper. and then polishing by using felt and diamond paste.It can use the clean polishing chamber in mold processing workshop directly if the polishing precision is Ra0.2, If the polishing precision is very high, then it must use an absolutely clean space to process. It will scrap the polishing surface in high precision if the space has Dust, smoke, dandruff and spittle.

I moved into a new apartment that had a storage area that the previous tenants did not vacate. After busting the lock I found these tires with rims. I am trying to get even a low ball estimate as to what I could sell these on offer up for. I hope this is an appropriate place to ask this question. If not I am happy to be pointed in a better direction. Thank you! 2 of the tires are obviously in better shape.
5G will become the preferred technology of V2V for automobile manufacturers. America will become the main market for deploying V2V technology.By Erica Zhu Feilong Jiangli
Chongqing Feilong Jiangli latest information. Juniper Research, a market research firm, predicts that by 2030, more than 62 million vehicles will have V2V communication capabilities, more than 1.1 million more than in 2019. V2V solution can achieve low delay communication between vehicles, especially to improve driver safety.
The new study by Juniper Research, titled Consumer Networked Automobile: Remote Information Technology, Vehicle Application & Networked Automobile Business 2018-2023, shows that the 5G network launched in 2019 will be the key driving factor behind the expansion of V2V communication technology. The study predicts that OEM will prefer to use 5G technology for V2V communications rather than other technologies because 5G technology has lower latency and higher radio frequency range.
Juniper Research found that the development of 5G technology will promote the commercial deployment and interoperability of 5G technology, and predicted that by 2030, the United States will become the main market for deploying V2V technology, and 60% of new cars sold in the United States will have V2V function. The technology could reduce the annual death toll in the United States by more than 9,300 people, accounting for 25% of motor vehicle deaths.
In addition, the study also predicts that manufacturers of automotive original equipment will explore new strategies such as on-board content subscription to generate revenue in addition to automotive sales. The study predicts that applications directly integrated into vehicles will generate more than $2.2 billion in revenue by 2030.
Juniper Research suggests that in addition to using 5G networks, OEMs must also open up their on-board ecosystems to third parties to accelerate the development of emerging and future automotive content revenue streams.

When selecting parts for a car repair, it pays to know the differences between original and aftermarket parts. Whenever possible, get estimates for both.
Choosing between original and aftermarket car parts — and even used parts of either type — is all about squaring your priorities with your budget.
You’ll have different options depending on the part and the shop. And the best choice will depend on whether you’re trying to keep repairs cheap, restore your car’s appearance after a wreck or soup up your ride.
Original equipment manufacturer (OEM) parts match those that came with your car, and are of the same quality as its original parts. They’re also the most expensive.
