Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Examples: referring to fig. 1-5, the present utility model provides a gear shaper cutter for machining rectangular internal spline deep grooves, comprising a blade 100, a tool shank 200, and a fastener 300. The horizontal cross section of the blade 100 is rectangular, the lower surface of the blade 100 is integrally formed with a cutter stem 101, a square hole 201 which is matched with the cutter stem 101 is formed in the cutter bar 200, the cutter stem 101 is completely embedded into the square hole 201, and the lower surface of the blade 100 is abutted with the upper surface of the cutter bar 200.
