1. Ordinary lathe

Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces. They are the most widely used type of machine tool processing in mechanical manufacturing(achievable accuracy 0.01mm).


2. Ordinary milling machine

It can process flat surfaces, grooves, various curved surfaces, gears, etc, and can also process more complex profiles (achievable accuracy 0.05mm).



A grinder is a machine tool that grinds the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools and free abrasives such as whetstones and abrasive belts. Such as super finishing machine tools, abrasive belt grinders, grinding machines and polishing machines, etc(achievable accuracy 0.005mm, small parts can achieve 0.002mm).



Mainly include filing, sawing, scoring, drilling, reaming, tapping and threading, scraping, grinding, straightening, bending and riveting, etc.


5.CNC lathe

Mainly processing batch products, high-precision parts, etc(achievable accuracy 0.01mm).


6.CNC milling machine

Mainly processing batch products, high-precision parts, complex parts, large workpieces, etc(achievable accuracy 0.01mm).


7.Wire cutting

The electrode used for the slow wire is brass wire, and the middle wire is molybdenum wire. Slow wire processing has high precision and good surface finish. Process some fine holes, fine grooves, etc(slow wire traveling can achieve an accuracy of 0.003mm, medium wire traveling can achieve an accuracy of 0.02mm).


8. Spark machine

Electrical discharge machining can process materials and complex-shaped workpieces that are difficult to cut with ordinary cutting methods (such as groove corners, small holes, deformed holes, and carbide processing on molds). There is no cutting force during processing, and no burrs or tool marks are produced. Defects such as grooves. Unaffected by material hardness and heat treatment conditions(achievable accuracy 0.005mm).
