This product is a high-speed motorized spindle for internal grindingmachine, with the maximum speed up to 400,000rpm. It can be used for high-speedprecision grinding machines. It is built-in with a three-phase asynchronousefficient motor, which is controlled at infinitely variable speeds through aninverter. This spindle is characterized with a compact structure, light weight,small inertia, small vibration and low noise, etc., so it can achieve highspeed, high precision and high operational stability.
Performance characteristics
1, high precision: grinding the shaft end of the hole full beating ≤ 0.002mm, spindle vibration ≤ 1mm / s, with unparalleled high-precision features.
2, high configuration: grinding spindle with temperature, vibration sensor (optional), the use of internationally renowned brands P2-class bearings.
3, the circulating water cooling + cold water cooling: cooling water forced to take the bearing and the heat generated by the processing, effectively inhibit the spindle temperature, reduce the spindle thermal deformation, to provide better processing accuracy and surface roughness. The center of the water-cooled way using the world's leading non-contact seal, to ensure the performance of the spindle seal under the premise of greatly improving the sealing life.
4, compatibility, good expansion: grinding spindle has a good compatibility, and has been successfully applied to a number of internationally renowned brands of grinding machines.
5, personalized custom: grinding spindle can be widely used in various types of metal, non-metallic grinding grinder, but also according to the special needs of customers customized.
6, the circulating water cooling: in the body to increase the cooling cycle of the waterway on the motor, before and after the bearing cooling. Coolant flow through the rational arrangement of the main body of the circulating cooling channel to take away the spindle when the high-speed rotation of the heat, to thermal equilibrium, so that the spindle temperature constant within a certain range to ensure the safety of the spindle, stable performance, cooling effect, efficiency High, small temperature rise, the spindle thermal elongation is small, the bearing force is small, to ensure the spindle life and spindle axial accuracy.
7, good seal: grinding wheel in the end of the labyrinth seal structure, which can effectively prevent the processing of cutting fluid and foreign body invasio
