TECHNICAL FIELD

[0001] The application relates to the technical field of cutters, in particular to a turning cutter for shell end face machining. BACKGROUND

[0002] A turning cutter is a cutter used for turning machining and provided with a cutting part. The turning cutter is one of the most widely used cutters in cutting machining. The working part of the turning cutter is the part for generating and processing chips, including a cutting edge, a structure for breaking or winding chips, a space for chip removal or chip storage, a channel for cutting fluid and other structural elements.

[0003] REFERENCE Figure 1 , Figure 1 The shell and the conventional turning cutter 2 are disclosed in the document. The shell is provided with two stepped holes at the middle position. The turning cutter 2 comprises a cutter bar 21 and a cutter blade 22. The cutter blade 22 is installed on the end of the cutter bar 21 by means of bolts.

[0004] During installation, the cutter bar 21 of the turning cutter 2 is installed on the lathe tool holder, and only the cutter blade 22 of the turning cutter 2 is exposed from the tool holder. During machining, the end of the shell is turned by the cutter blade 22. However, when machining the stepped hole, the cutter bar 21 is located inside the tool holder, and the distance between the cutter blade 22 and the tool holder is small. If the stepped hole is machined, the tool holder will inevitably collide with the shell, so that the turning cutter 2 cannot smoothly machine the stepped hole, and the applicability of the turning cutter is reduced.
