Common Problems in CNC Lathe Processing
The problems and difficulties of VNC lathe in the process of processing are as follows:
First, how to deduce the good condition and service life of the tool?
In the process of automatic machine tool processing, it is necessary to use ear cutting to listen to the sound, stop the machine to inspect or touch the tool tip on time, and deduce according to the analysis of surface brightness, etc.
Second, how to select the appropriate tool according to the material characteristics?
In the process of processing, if the tool is not selected correctly, it will cause unstable or impossible processing, and affect the efficiency, but also can not make a good character. So it’s very important to choose cutting tools. When we process hard materials, we should choose rigid tools with strong tool tips. The machine should also use the principles of low speed, slow feed and less back eating to debug. Then when processing soft materials, such as aluminium alloy, nylon rod, copper and so on, we should correspond. What’s more, it’s better to increase the speed, feed rate, back feed rate, and use the corresponding alloy knife! Unique is that the slow feed table will cause slag extrusion, work piece winding, no slag crushing. This will greatly affect efficiency and character!
Third, what happens when the process or knife path is not arranged properly to affect the efficiency?
1. Similarly, although the knife should not be used repeatedly, it is absolutely not necessary to use the second knife when one knife can be finished. When the conditions permit, the sequence and procedure of knife arrangement must be arranged according to the knife path, so as to minimize the idle travel time, reduce unnecessary positioning deviation, and have the advantage of once again without the influence of the knife or the quality. Procedure, to reach a good processing form!
Fourthly, what about simple deformation when processing thin-walled products?
Such a product is a bit difficult, some may be divided into many processes to complete, may as well be based on product requirements, to analyze and infer! Surely to use low speed, slow feed, less back eat three major processing factors! And to choose a small tip, sharp blade against the tool, clamp as far as possible to choose the axial clamp (such as screw pressing). Silk sleeve, if radial tightening is used, there will always be deformation!
