Conventional Gear Shaving Cutter

There are many narrow grooves forming cutting edges on the tooth surface, and the gear-shaped gear processing tool is used to process the workpiece according to the principle of helical gear meshing. During processing, the cutter cuts off whisker-like fine chips from the tooth surface of the gear, so it is called a shaving cutter. The shaving cutter is used to finish the gear teeth after hobbing and shaping (see gear machining). The commonly used disc shaving cutter is like a hardened helical cylindrical gear. There are two forms of grooves on the tooth surface: one is a circular or helical through groove on the entire ring gear, and the grooves have two grooves. The cross section can be rectangular or trapezoidal. This kind of shaving cutter is blunt and only the front (slot) is sharpened, and the tooth shape and outer diameter do not change. Since the through groove cannot be made too deep, it is only suitable for modules. Razors less than 1.75 mm; the other is that the grooves on both sides are blocked, and they are inserted separately with comb-shaped inserts. small holes. This kind of razor needs to be reground tooth shape and tooth top cylindrical surface after blunt use.
