Machining:
The full name of machining refers to the processing of the workpiece through various mechanical equipment to make it reach the predetermined shape, size, accuracy and surface quality requirements, which is one of the core links of modern manufacturing.
The use of lathe to rotate the workpiece, the tool for linear feed movement, mainly used for processing the surface of the rotary body, such as shaft, disk parts of the outer circle, inner hole, cone, thread and so on. High turning precision, up to IT6-IT8 level, surface roughness Ra up to 0.8-1.6μm, often used for roughing and finishing of mechanical parts.
Using a drill press, the tool is rotated and fed axially for processing holes, such as drilling, reaming, reaming, etc. Drilling is the most basic operation, can directly drill a certain diameter of the hole, but the accuracy is low; Reaming is to enlarge the existing hole to improve its dimensional accuracy. Reaming can further improve the accuracy of the hole, to IT7-IT9 level, surface roughness Ra is 0.8-1.6μm, often used for hole processing of mechanical parts. Is the main equipment of machining, a wide variety, such as lathes, milling machines, drilling machines, grinding machines, boring machines, planers and so on.
Different machine tools have their specific functions and scope of application, in order to meet the complex processing needs, the modern manufacturing industry often uses the machining center, which sets a variety of processing functions in one, can automatically change the tool, to achieve continuous and efficient processing of the workpiece.
