The tooth profile cutter is a special tool for milling the forming surface of the workpiece. Its blade shape is calculated based on the profile of the workpiece. It has a high productivity, and can ensure the interchangeability of the shape and size of the workpiece. Therefore, it is widely used. Forming cutter can be divided into two kinds of teeth and sharp teeth according to the back shape.
1. Tip-Shaped Milling Cutter: The tine-forming cutter has a large number of teeth and a reasonable relief angle, which makes the cutting light and smooth, the machining surface quality is good, and the milling cutter life is high. However, sharp teeth forming cutters require special dies or grinding on the back of a CNC tool grinder. The sharpening process is complicated. Therefore, a simple blade-shaped forming cutter is generally made into a sharp tooth shape.
2. Tooth profile cutter: The back of the teeth is formed by a radial cut so that it has a profiled blade relief angle. After the tool is reground along the rake face, the shape of the cutting edge can be ensured. Therefore, the tooth structure is generally used in production, and only the sharp tooth structure is used in mass production.
