The machining process in Dalian can be divided into casting, forging, stamping, welding, mechanical processing, assembly and other processes. The mechanical manufacturing process generally refers to the sum of the machining process of parts and the assembly process of machines, while other processes are called auxiliary processes such as transportation, storage, power supply, and equipment maintenance. Craftsmanship consists of one or more sequentially arranged processes, with each process consisting of multiple steps.

Turning (vertical lathe, horizontal lathe): Turning is the process of cutting metal from a workpiece. While the workpiece rotates, the tool cuts into or turns along the workpiece;

Milling (vertical milling, horizontal milling): Milling is the process of cutting metal using a rotating tool, mainly used for machining grooves and straight surfaces, and can also be used for two or three axis linkage machining of curved surfaces

Boring: Boring is a machining method that enlarges or further processes holes that have already been drilled or cast on a workpiece. Mainly used for machining holes with larger shapes, larger diameters, and higher precision of workpieces.

Planing: Planing is mainly characterized by processing straight surfaces, and in general, the surface roughness is not as high as that of milling machines;

Insertion cutting: Insertion cutting is actually a vertical planer, and its cutting tools move up and down, which is very suitable for incomplete arc machining and mainly used for cutting certain types of gears;

Grinding (flat grinding, external cylindrical grinding, internal hole grinding, tool grinding, etc.): Grinding is a machining method that uses grinding wheels to remove metal, resulting in accurate dimensions and smooth surfaces of the processed workpiece. Mainly used for precision machining of heat-treated workpieces to achieve accurate dimensions.

Drilling: Drilling is the use of a rotary drill bit to drill holes on solid metal workpieces; During drilling, the workpiece is positioned, clamped, and fixed in place; In addition to rotation, the drill bit also needs to perform feed motion along its own axis.
