Because the tool material is very hard, generally only grinding can be used to change its shape. Common tool grinding machines in the manufacture and grinding of tools are as follows:
1. Groove grinding machine: Grinding the groove or back of drill bits, end mills and other tools.
2. Top angle grinding machine: grind the cone top angle of the drill bit.
3. Chisel edge repairing machine: correct the chisel edge of the drill bit.
4. Manual tool grinding machine: grinding outer circle, groove, back, top angle, chisel edge, plane, rake face, etc. It is often used for knives with small quantities and complex shapes.
5. Five-axis linkage CNC grinding machine: the function is determined by the software. It is generally used for grinding tools with a large quantity and high precision requirements, but not complicated, such as drill bits, end mills, etc.
Grinding wheel
Grinding wheel grains of different materials are suitable for grinding tools of different materials. Different parts of the tool need to use different sizes of abrasive grains to ensure the combination of edge protection and processing efficiency.
Aluminum Oxide: Used for grinding HSS knives. The grinding wheel is cheap and easy to modify into different shapes for repairing complex (corundum) tools.
Silicon carbide: used to correct CBN grinding wheel and diamond grinding wheel.
CBN (cubic boron carbide): used for grinding HSS tools. Expensive, but durable. Internationally, for grinding wheels
B to represent, such as B107, where 107 represents the size of the abrasive grain diameter.
Diamond: used for grinding HM knives, expensive but durable. D is used on the grinding wheel, such as D64, where 64 represents the diameter of the abrasive grain.
