Hardware accessories processing vehicles, milling, planing, grinding, pliers, stamping, casting, and so on. The most common are the following two:
1, lathe: lathe is a precision machining machinery, there are divided into ordinary lathe, automatic lathe, instrument lathe and computer lathe. It is by holding the material after the rotary motion, by turning the radial or axial processing. Now automatic lathes and computer lathe applications more and more widely. Because these two are fully automated processing, the accuracy of the error generated by the operation to the lowest point, and processing speed, for mass production. Now most of the computer lathes are equipped with side rotary tool and the back of the rotary tool, that is to say on the lathe can also be milling. Lathe processing surface roughness of about Ra0.4-1.6.
2, stamping: punching a good pre-made with a punch punch mold for processing, mainly for sheet metal processing, that is, most of the material processing sheet, the processing efficiency is relatively high for mass production. The process is divided into engineering and continuous mode, the mold is also called a single die, and some more complex parts to use several sets of mold; and continuous mold cavity in the mold product shape split several parts in a Mold, so punch a trip is a finished product. High-speed continuous punch can process three or four hundred products per minute.
