4.5 kW Air Cooled CNC Spindle Motor 18000 rpm ER32
Brief
Description
4.5 kW CNC spindle motor, 18000 rpm speed, 2.27 Nm torque, 300Hz frequency, 3 phase 380V AC operating voltage, ER32 (φ3.175 mm - φ20 mm) collet.
Feature
- Spindle motor with air cooling fan and ER32 collet ensures smooth running.
- Fast response, strong overload capacity, low noise and high mechanical precision.
- High quality 4 pcs bearings (7008Cx2 + 7002Cx2), runout off less than 0.01mm, tapered bore less than 0.005mm.
- P4 grade ceramic ball bearings used as spindle bearing, which improves the service life under high speed revolution.
- Lubricated with grease, which is resistant to 200 degrees high temperature.
- Tight sealing and two-layer dustproof design.
Application
This series air-cooled electric spindle motors mainly match with variable frequency drives or engraving machines, CNC router machine, and used for high speed profiling, drilling, cutting, engraving and groove milling of wood, metal, plastics, foam, rubber and other materials.
Note: The spindle motor and VFD shall be suitable with each other. The specifications and parameter settings of the VFD shall match the nominal parameters of the spindle motor. Otherwise, it will burn the spindle motor if the settings are not correct.

Tips: Speed Range of Spindle Motor in CNC Machine When Processing
Under normal processing conditions, the main parameter affecting tool life of woodworking engraving machine is spindle motor speed. Under the same conditions, the lower the spindle motor speed, the longer the tool life. In order to prolong the service life of the tool, it is desirable to set a lower spindle speed, but the speed of the spindle motor can not be reduced indefinitely. When the speed of the spindle motor is too low, the cutting force becomes larger at the same feed speed, which makes the tool unbearable. So there is a reasonable rotational speed range for spindle when processing certain materials.
