The main forms of machining are: turning machining, milling machining, package machining and grinding machining. Traditional machining methods mainly include: turning, clamping, milling, planing, inserting, grinding, drilling, boring, punching, sawing and other methods. There are also electroplating, casting, wire cutting, forging, electro-etching, powder processing and so on.
Turning: mainly processing shaft or rotary parts, through the turning of the tool to make it achieve the desired shape;
Milling: mainly processing plane, or bevel, through the milling cutter disc to remove the plane;
Planing: mainly for machining flat or curved surfaces, and removing the flat or curved surfaces by planing cutters;
Grinding: mainly by grinding wheel to grind the plane, external circle, internal circle to achieve the surface roughness;
Drilling: mainly by drilling holes with a drill;
Boring: mainly by boring the bore with a boring tool or insert.
Punching: Mainly by punching and forming;
Sawing: mainly by sawing machine cutting processing.
If the product batch is large, it is recommended to use the lathe to bore, which is fast and accurate. Because it is clear angle, so the boring tool should also clear the angle in front;
If the product batch is small, use milling cutter milling but the speed is slower. Machining is a process of changing the size or performance of a workpiece with machining machinery. According to the temperature state of the workpiece being machined, it is divided into cold machining and hot machining. Machining at room temperature and without chemical or physical changes to the workpiece is called cold machining.
Generally at a higher or lower than room temperature state processing, will cause chemical or physical changes in the workpiece, called hot processing. Cold processing can be divided into cutting and pressure processing according to the differences in processing methods. Thermal processing is common with heat treatment, calcination, casting and welding.
