Broaching is a precision machining method that uses a broach to move linearly across the surface of a workpiece. Its core lies in the progressive cutting of a multi-toothed tool, with each tooth having a slightly different cutting depth, thus achieving efficient and precise material removal. This machining method is particularly suitable for machining complex shapes such as internal holes and keyways, and can accomplish in one operation the results that would require multiple steps in traditional methods.
Cutting Logic: Broaching can be understood as a compound planing process where multiple broaches are arranged in descending order of height. Each broach tooth bears only a small cutting amount, resulting in a smooth cutting process and minimal workpiece deformation.
Final Forming: The calibrating tooth at the end of the broach is perfectly aligned with the final requirements of the workpiece, serving to calibrate dimensions and smooth the surface. Roughing, semi-finishing, and finishing can be completed simultaneously in a single pass.
