In the process of mechanical parts processing, general parts processing technology often contact with the completion of turning and milling machine. And turning and milling machine processing mechanical parts, sometimes also encounter technical problems. For example: the blade installed on the lathe tool follows closely and protrudes slightly than the blade for cutting. The purpose is to process good surface roughness of parts. Eccentric turning starts from the center of the rotating workpiece to ensure that the cutting edge cuts into the workpiece slowly.
First of all, the importance of cutting: cutting parts need to remove a lot of machining allowance, turning and milling machine processing should be the best choice. Discontinuous cutting: turning tool is usually not good for discontinuous cutting, but milling cutter can do it well. Milling is often defined as a kind of discontinuous cutting. Therefore, in the case of discontinuous cutting, it should be thought of turning to milling. Excellent chip breaking processing: over the years, machining practice has proved that for some equipment parts, milling instead of turning can eliminate the previous phenomenon of “bird’s nest” shaped chips entangled in the cutter head. Because the milling process with the advantage of natural chip breaking is combined in cutting, the continuous chips are broken into small pieces which are easy to be eliminated.
Flexible shaft machining: when turning long and thin parts which can not be supported in the middle, milling can prevent the parts from bending. Compared with turning, in theory, milling can cut parts under very small pressure. But in fact, a lot of technical problems need to be solved.
Continuous time processing: in the cutting of difficult to machine materials, the service life of a turning tool is very short, while the milling cutter can be used for a long time because it distributes the cutting load through multi edge cutting. Because the milling cutter has a long service life, it can save the trouble of changing the cutter many times during cutting. Eccentric processing or special-shaped processing: the radial (x-axis) movement of milling cutter can be consistent with the rotation movement of workpiece, and it has certain processing advantages to process the contour of complex parts.
The above is about the mechanical parts milling machine processing technical problems, thank you for sharing!
