Precision machining cannot be done without tools, and it can be said that tools are the lifeline of precision parts machining. Many CNC machining process, have made the requirements for the tool. Without a good tool, mechanical parts processing plant almost inch hard to move
During the machining of precision parts, tools are often changed. But for cost reasons, it is not possible to replace the tools at will. For precision machining operation employees, it becomes a professional skill to push to the excellent condition and service life of the tool. In the automatic processing process, the need to use the ear to listen to the sound of cutting, in the cutting process, it is necessary to stop on time to inspect or touch the tip of the tool, according to the surface brightness analysis whether to replace!
In addition, skilled precision machining operation employees must be able to select the corresponding tool according to the material characteristics. The choice of tool is matched according to the material of precision parts processing. When processing the material relatively hard workpiece, should be selected with rigid control, tool tip large tool to hard against hard, must be when the corresponding hardness of the tool, the machine should also be selected with low speed, slow feed, less back eating and other principles to debug.
By the same token, when processing materials against soft precision parts processing, such as nylon rods, aluminum, copper and other materials, the process of precision machining may wish to elevate the speed, feed, back eat knife amount, and should choose the appropriate alloy knife! If when the feed is too slow, it will cause squeezing slag, to the workpiece winding, not crushing slag, or have other unexpected situations, which will greatly affect the efficiency and character!
In the process of precision machining, if the tool selection is not right, it will cause the instability of precision machining, and affect the efficiency of other CNC machining processes, but also can not do good quality, so the choice of tools is very important!
