Turning and milling has been an unclear term. A turning center equipped with a rotary tool function is sometimes called a turning and milling machine. And there is a special metal machining operation that really deserves to be called "turning and milling", that is, using a rotating milling cutter to cut while the workpiece is rotating.

There are several reasons why the shop wants to use this method of processing. Easy control of the chip is one of them. Another reason for intermittent cutting. At least one tool supplier, Sandvik Coromant, has seen that car milling is used frequently and will have good market prospects. They have developed special tools for this operation. Jim Grimes, Sandvik's product specialist, provides a lot of information about turning and milling technology for this article. He said that with the advanced use of multi-function lathes, turning and milling is no longer processed as often imagined. Today's users of turning and milling machines will realize that this new processing method is obtained without One is not to overcome the drawbacks of traditional car processing.

The wiper blade mounted on the tool follows and is slightly more prominent than the blade that is being machined. The goal is to machine the surface roughness of a good part.

Eccentric turning is performed from the center of the rotating workpiece to ensure that the cutting edge slowly cuts into the workpiece.

The following are some of the challenges of special technical problems solved by turning and milling:

Large metal removal rate processing: If turning parts need to remove a lot of margin, turning and milling should be the best choice.

Intermittent cutting: Turning tools are usually not well used for interrupted cutting, but milling cutters do a good job. Milling is often defined as a discontinuous cut. Therefore, whenever it is encountered in the case of intermittent cutting, it should be thought to change the turning machining to turning and milling.

Excellent chip breaking processing: The practice of multiple machining proves that for some parts and materials, turning and milling can be used instead of turning machining, which can eliminate the phenomenon of “bird's nest”-like chips wound around the cutter head. Because the milling combines the milling process with the advantages of natural chip breaking, the continuous chips are broken into small pieces that are easy to remove.

Flexible shaft machining: When turning long and thin parts that cannot be supported in the middle, the use of turning and milling can better prevent the parts from being bent (bent) during processing. In contrast to turning, in theory, milling can cut parts with little pressure on the tool. But in fact, there are still a lot of technical problems to be solved.
