What is the spindle of the CNC router:
The cnc router spindle is an electric spindle that can be processed at a high speed. It is widely used on wood engraving cnc router,cnc milling machine,metal cnc router etc… It can be mainly used for high-speed engraving, drilling and milling, punching, etc., involving a wide range of industries.
Notes for the installation of the spindle of cnc router:
CNC engraving router machine, cnc milling machine spindle is a high-speed, high-stiffness and fine motor, which is supported by fine rotating bearings, grease lubricated, and external circulating water cooling.The engraving (milling) spindle is usually used vertically, and the method used is accurate or not. It directly affects the quality of engraving, engraving and milling, and the service life of the spindle.
1. Prevent impact
Violent impact, except that the end of the spindle and the front end cover must not be impacted, otherwise it will damage the precision of the fine bearing and the spindle, and cause the loss of the accuracy of the spindle’s reverse rotation.
2. Accurate placement and clamping
Before installation, confirm that the spindle motor is in normal condition. Importantly, there is no damage on the surface and the spindle rotates gently and evenly. Use a 500V shaker to check that the insulation resistance to ground of the stator is above 100 ΠΌΩ. The common service between the outer diameter of the spindle motor sleeve and the clamping seat hole must ensure that the spindle motor sleeve can smoothly slide into the seat hole. Under any environment, it is impossible to use a hammer or other things to position the spindle and the clamping force It should not be too large, otherwise it will cause deformation of the steel ball raceway of the fine bearing, which will affect the accuracy and life of the spindle. After clamping, check the beating of the relief surface of the cone hole at the front end of the spindle should be no more than 0.005MM, and the spindle reversal spreads and rotates smoothly.
