Description

Technical Field

[0001] The utility model relates to a grinding machine for grinding three-hole blades. Background Art

[0002] Grinding machines are mainly used in the field of machining for grinding products or objects. Different grinding accuracy and structures are required for the objects, which leads to different requirements for the grinding accuracy and structure of the grinding machines. Therefore, grinding machines of different specifications, styles and functions are developed.

[0003] Three-hole blades are also relatively common in daily life. For example, the blades on ordinary razors are three-hole blades. Although such blades have a certain hardness, they are generally relatively thin. Therefore, the grinding of the cutting edges on both sides puts higher requirements on the stability and precision of the grinder. Usually, the grinding of three-hole blades requires grinding multiple surfaces of the cutting edges on both sides to complete. When grinding the blade, the existing grinder needs to clamp and grind back and forth multiple times to complete the entire three-hole blade grinding operation. Its production efficiency is low, and repeated clamping causes the grinding accuracy to decrease. Therefore, it is necessary to develop a new type of grinder for three-hole blade grinding.
