CNC precision machining is very small in order to control precision, smoothness, knife consumption and feed rate. The cutting temperature of the whole equipment is low, which can increase the cutting speed and increase the processing time. The most important thing is A certain increase in cutting speed can avoid the generation of the acupuncture biofilm and improve the processing accuracy and smoothness.
CNC finishing In the programming, the programmer must fully grasp the geometric element parameters that make up the part contour and the relationship between the geometric elements, because all geometric elements of the part contour need to be defined during automatic programming.
The machining process of CNC finishing is often concentrated, and positioning with the same benchmark is very important. It is therefore often necessary to set up some auxiliary references or to add some process bosses to the blank. The shape and inner cavity of the part are preferably of a uniform geometry type or size, which reduces the number of tool changes, and may also use a control program or a dedicated program to shorten the program length. The shape of the part is as symmetrical as possible, which is easy to program with the mirror machining function of the CNC machine to save programming time.http://www.pump-casting.com/
