Friends engaged in mechanical processing may also understand the principle of mechanical processing, but for some who just contact this industry may not be very clear, let's take a look at the principle of mechanical processing together with Shanghai machining manufacturers.

Principle of mechanical processing:

Mechanical processing is a process of changing the size or performance of the workpiece with processing machinery. According to the temperature state of the workpiece being processed, it is divided into cold processing and hot processing.

In addition, hot and cold treatment is often used in assembly. For example, when bearings are assembled, the inner ring is often put into liquid nitrogen to cool it so that its size shrinks, the outer ring is properly heated to enlarge its size, and then it is assembled together. The outer rings of train wheels are also heated and attached to the substrate, so that they can be fastened securely when cooled (this method is still used in the transfer of some parts).

Mechanical processing includes: filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, sheet metal bending forming, die forging, water jet cutting, precision welding, etc.
