Multi-station PCD forming cutter

Technical Field

The invention relates to the technical field of metal cutting machining tools, in particular to a multi-station PCD forming tool.

Background

The traditional machining process of the aluminum alloy automobile starter driving end cover adopts a numerical control lathe, the appearance of the aluminum alloy automobile starter driving end cover belongs to special-shaped parts, the coaxiality of key sizes such as a bearing position and the like cannot be guaranteed due to the centrifugal force generated by the rotation of the parts during machining on the lathe, the diameter size is unstable, and a large amount of time is needed for detecting the size. Therefore, the fixed part is generally processed by the PCD forming cutter, and when the special-shaped part is processed by the PCD forming cutter, the special-shaped part is difficult to be processed in one step, the special-shaped part needs to be processed by being divided into a plurality of processing positions, and the special-shaped part finished product can be obtained after different processing positions are processed for a plurality of times by different cutters, so that the special-shaped part is frequently changed in the processing process, and the process is complicated. The machining efficiency of parts is influenced, and therefore a multi-station PCD forming cutter is provided.
