Introduction to Tool Grinding Motorized Spindle
Tool grinding Motorized spindles are mainly used in automatic CNC tool grinding machines, which can rotate in both directions and grind in multiple directions, and are used for processing various sizes of tools such as drills, milling cutters, taps, turning inserts, etc. Tool grooving and sharpening is completed in one clamping process; this series of Motorized spindles can not only withstand large radial force, but also a certain amount of axial tension and thrust, and has the characteristics of high precision and high rigidity.
With the development of tool grinding Motorized spindle, the motor gradually adopts copper rotor or permanent magnet synchronous motor, the motor efficiency and energy saving are improved simultaneously, and the pressure air sealing technology is adopted to improve the air sealing structure, which ensures the reliability of spindle operation and long life of 24-hour continuous operation.
