Spindle of Roctech CNC engraving machine

The spindle of the engraving machine is a kind of electric spindle that can process at high speed and is widely used in some small and medium-sized engraving machine equipment. It can be used for high-speed engraving, drilling and milling, punching, etc., involving a wide range of industries. In the choice of engraving machine spindle, the first thing to consider when carving which material. Generally speaking, carving hard metal materials, to choose the torque and power of the spindle is relatively large, because carving hard materials, power is too small easily lead to carving process jitter, or even broken knife; carving texture is not very hard materials such as acrylic, non-metallic materials, as a rule, will choose a higher speed spindle.

      Roctech CNC engraving machine spindle features

     1. High-speed electric spindle bearings all use C-class high-speed angular contact ball bearings, with preload in the axial direction to improve the support rigidity and grinding accuracy of the spindle under high-speed rotation.

    2.The electric spindle can be lubricated by high speed grease and oil mist according to different speed applications.

    3. The temperature rise caused by the high speed rotation of the electric spindle is eliminated by using the coolant circulation system.

     How to maintain the spindle of Roctech CNC engraving machine

    1. The rated voltage and frequency of the medium frequency power supply connected to the electric spindle should be consistent with the technical parameters of the electric spindle, the electric spindle speed can be adjusted by changing the frequency, while the voltage is also proportional to change.

   2. used electric spindle is not used temporarily, the application of compressed air blowing coolant in the hydrostatic tube. To avoid rusting and blocking the water hole. Electric spindle exterior should be coated with anti-rust oil. 3. If you need to replace the bearing, let the technician replace it. When replacing the bearing should be cleaned, the stator coil, do not have to remove.   

      Because the processing of different materials, we choose different spindle, some spindle maximum speed is 24000 rpm, some can reach 30000 rpm, so different industries choose different spindle, different materials to use different speed processing, the use of spindle is also different.
