1、 What is a gear cutter

Gear shaping cutter is a metal processing tool used to cut tooth slots on metal workpieces. It is commonly used to manufacture workpieces such as gears and racks, and has efficient and precise processing capabilities. The basic parameters of a slotting cutter include tool geometry, tool material, tool coating, etc.

2、 Basic parameters of gear shaping cutters

Tool geometry

The geometric shape of the slotting cutter has a significant impact on the machining effect and cutting force. The common geometric shapes of the cutter include the following parameters:

Blade inclination angle: The blade inclination angle determines the cutting force and cutting depth of the tool during cutting. The smaller the blade inclination angle, the smaller the cutting force, and the smaller the cutting depth

Blade radius: The blade radius determines the sharp angle radius of the cutting teeth. A larger tool tip arc radius can reduce cutting force and improve tool life.

Blade thickness: The blade thickness determines the strength and stiffness of the blade teeth. A larger blade thickness can increase the stiffness of the teeth and improve machining accuracy.

2. Tool material

The tool material of the gear shaping cutter has a significant impact on the cutting effect and tool life. Common tool materials include

High speed steel: High speed steel has high hardness and wear resistance, suitable for general gear shaping processing.

Hard alloy: Hard alloy has extremely high hardness and wear resistance, suitable for gear shaping of high-temperature and high hardness materials.

3. Tool coating

Tool coating can improve the wear resistance of tools and reduce friction coefficient, thereby extending tool life and improving machining efficiency.
