How many surface treatment processes do you know or have been exposed to? Don’t worry, I will share 21 types today, and the moving pictures will help us understand. 1. Micro-arc Oxidation Micro-arc oxidation, also known as micro-plasma oxidation, is a combination of electrolyte and corresponding electrical parameters. On the...

The effect of four types of stainless steel and alloy elements There are four types of stainless steel: austenitic, martensitic, ferritic, and duplex stainless steel (Table 1). Table 1 Stainless steel types and their Cr and Ni element contents Types Cr/% Ni/% Grade Austenite 16-30 8-40 200，300 Martensite 11-18 0-5...

Sheet metal processing technology is constantly improving, especially in some precision stainless steel bending, stainless steel decorative parts bending, aluminum alloy bending, aircraft parts bending, copper plate bending and other applications. Further requirements are imposed on the surface quality of the formed workpiece. The traditional bending process is more likely to...

1. EDM (1) Basic principles Electrical Discharge Machining is a special processing method that uses electro-corrosion generated during pulse discharge between two electrodes immersed in working fluid to remove conductive materials. Also known as electrical erosion machining. EDM is suitable for the processing of complex parts such as small precision cavities,...

Construction machinery is inseparable from the oil cylinder, and the oil cylinder is inseparable from the seal. Common seal is sealing ring, also called oil seal, which plays a role of insulating oil and preventing oil from overflowing or passing through. Common seals for hydraulic cylinders include the following 6...

Polishing not only increases the aesthetics of the workpiece, but also improves the corrosion and abrasion resistance of the material surface. It can also make the mold have other advantages, such as making plastic products easy to demold, reducing the production injection cycle and so on. Therefore, polishing is a...

It must be said that the development momentum of laser cutting machines in recent years is indeed rapid. As the “darling” of metal processing in the new era, the laser cutting machine can be said to be the product of modern science and technology. It replaces the traditional mechanical knife with “beam”...

A lot of people want to know the world’s best CNC press brake manufacturers, or top 10 press brake manufacturers, however, very few of them will choose these best press brake in the world. There is only one reason: expensive. The high price does not mean the machine is good. Just because...

1. Daily inspection and maintenance of laser cutting machine Check the pressure of the laser working gas and cutting gas carefully before turning on the machine every day. If the gas pressure is not enough, it should be replaced in time. Check whether the X-axis zero point, Y-axis zero point,...

Annealing, normalizing, quenching, tempering, quenching and tempering … totally 12 heat treatment processes. This article will help you sort out. 01 Annealing Operation method: After heating the steel to a temperature of Ac3 + 30 -50 degrees or Ac1 + 30 – 50 degrees or below Ac1 (you can consult...
