Problems solved by technology
[0002] Existing reamers used for machining cylinders are prone to errors when placed on the spindle of the machine tool, which leads to large jumps in the edge of the tool. Long-term use will cause the edge of the tool to collapse, which will not only affect the machining accuracy but also It affects the life of the tool; and the cutting resistance of general reamers is poor, and there is room for further improvement in self-guiding performance and smoothing performance

The invention discloses a PCD compound reamer which comprises a handle. The tail end of the handle is mounted on an adjustable flange, the front end of the handle is connected to a body, spiral chip removing slots in central symmetry are formed in the circumferential face of the body, a tool bit is arranged at the front end of the body, chutes communicating to the chip removing slots in a same spiral line are formed in the tool bit, each chute is provided with a mounting face and a transitional face joined to the opening in the front end of each chip removing slot, a blade is mounted on the mounting face, a cutter tooth is arranged between two adjacent chutes, and the front angle of the cutter tooth is 5-10 degrees. A plurality of teeth are distributed on the circumferential face of the cutter tooth, each tooth is provided with a margin, and an annular slot is formed in the back side of the tool bit of the body. The PCD compound reamer disclosed by the invention has a self-guiding property and a good sleeking effect and is sharp to cut, and the processed part is smooth in surface.
Description
technical field [0001] The invention relates to a reamer, in particular to a PCD compound reamer. Background technique [0002] Existing reamers used for machining cylinders are prone to errors when placed on the spindle of the machine tool, which leads to large jumps in the edge of the tool. Long-term use will cause the edge of the tool to collapse, which will not only affect the machining accuracy but also It affects the life of the tool; and the cutting resistance of general reamers is poor, and there is room for further improvement in self-guiding performance and polishing performance. Contents of the invention [0003] In view of the deficiencies in the background technology, the present invention provides a PCD compound reamer. The technical problem to be solved is how to effectively enhance the self-guiding performance and smoothing performance of the reamer, and improve the processing quality and service life of the reamer. [0004] In order to solve the above tec...
