Precision hardware processing technology processes include turning, milling, planing, grinding, clamping, stamping, forging and other methods.
Stamping: the pre made die is used for cold stamping, and the first step is sheet metal processing, that is, most of the processing materials are sheet metal, so the processing efficiency is relatively high and suitable for mass production.
The process of fine hardware processing technology is divided into engineering die and connecting die. Engineering die is also called single punch die. Some more complex parts need several sets of dies, and the connecting die splits the shape of the commodity into several parts in the cavity of the die. In this way, a punch processing stroke is a finished product. High speed continuous punch can process 300 or 400 products per minute.
Lathe: lathe belongs to precision machining machinery, which is divided into general lathe, active lathe, instrument lathe and computer lathe. After holding the material clip, it reverses and processes radially or axially by the turning tool.
Nowadays, active lathe and computer lathe are more and more widely used. Because both of them are fully active processing, the accuracy error caused by human operation is reduced to the lowest point, and the processing speed is fast, which is used for mass production. Most of today’s computer lathes are equipped with side reverse cutter and reverse reverse cutter, that is to say, milling can also be carried out on the lathe. The surface roughness of lathe is about ra0.4-1.6;
