Current background

The current sharpening machine industry is in a stage of technological upgrading and diversified demand. With the advancement of intelligent manufacturing, CNC sharpening machines, with their advantages of high precision and automation, are accelerating the replacement of traditional manual equipment in fields such as metal processing and maintenance of catering utensils. Meanwhile, driven by environmental policies, energy-efficient and low-noise designs have become a focus of research and development.

Motor selection

Motor performance: It needs to meet the requirements of industrial grade load and continuous operation. It is recommended to choose high specification models for power (suitable for hard alloy, ceramic and other high hardness cutting tools), and the torque should be sufficient to support the load during the rough grinding stage to avoid jamming. The speed should support stepless speed regulation, low-speed temperature control during rough grinding stage (suitable for hard alloy and ceramic cutting tools), and high-speed efficiency improvement during fine grinding stage (suitable for high-speed steel, etc.). The recommended cooling system is a combination of liquid cooling and air cooling, combined with intelligent temperature control to avoid performance degradation caused by high temperatures. Priority should be given to low vibration motors for noise control, and high dynamic balance accuracy is required to ensure even grinding surfaces at high speeds.

Grinding head selection

Grinding head adaptation: The material should be selected based on the characteristics of industrial cutting tools. Diamond grinding heads are preferred for hard alloy and ceramic cutting tools (with strong wear resistance), CBN grinding heads are selected for high-speed steel and quenched steel (with high temperature resistance), and silicon carbide can be used for ordinary steel (with excellent cost-effectiveness). Geometric design needs to strengthen chip removal and accuracy, multi blade structure to improve rough grinding efficiency, spiral angle design to reduce vibration and improve surface smoothness; Particle size matching in stages (coarse grinding uses coarser particle size to quickly remove chips, fine grinding uses finer particle size to ensure accuracy), and binder selection (resin binder removes chips quickly, ceramic binder has high accuracy). The convenience of replacement needs to support quick change design to reduce downtime, and be compatible with non-standard grinding heads to meet customized needs
