Processing method of large mechanical parts:
Connecting pieces: screws and bolts.
Transmission parts: gear, chain, worm and belt.
Shafting parts: shaft, coupling, clutch and bearing.
There are other components: springs, etc.
The processing methods of large mechanical parts mainly include: turning, pliers, milling, planing, inserting, grinding, drilling, boring, punching, sawing, etc.
It can also include wire cutting, casting, forging, electric corrosion, powder processing, electroplating, various heat treatment, etc.
Car: vertical car and horizontal car; The new equipment is CNC lathe, which mainly processes revolving bodies;
Milling: vertical milling and horizontal milling; The new equipment is CNC milling, also called machining center; It is mainly used to process grooves and linear surfaces. Of course, it can also process cambered surfaces with two or three axes;
Planing: it mainly processes the linear surface of the contour, and the surface roughness processed under normal conditions is not as high as that of the milling machine;
Insertion: it can be understood as a vertical planer, which is very suitable for non complete arc processing;
Grinding: there are surface grinding, external open powder satin and other crazy round grinding, internal hole grinding, tool grinding, etc; For high-precision surface processing, the machined workpiece surface roughness is particularly high;
Drilling: hole processing;
Boring: machining of holes with larger diameter and higher accuracy, and machining of larger workpiece profiles. There are many processing methods for holes, such as numerical control processing, wire cutting, etc.
Boring: mainly boring the inner hole with boring cutter or blade;
Punching: It is mainly formed by punching machine, and can punch round or special-shaped holes;
Saw: It is mainly processed by sawing machine, and is commonly used in blanking process.
