  • Frequency: 0-300Hz

  • Speed: 0-18000rpm

  • Runout Off: Less than 0.01mm

  • Bearing type: 2x7007C P4 DB ( Ceramic ball bearings ) & 2x7002C P4 DT

  • Collet: ER25

  • Clip Knifediameter: 1mm,2mm,3mm,3.175mm(1/8),4mm,5mm,6mm,6.35mm(1/4),7mm, 8mm,9mm,10mm,11mm,12mm,12.7mm(1/2),13mm,14mm,15mm,16mm

  • Grease Lubrication 

  •  Main Application:  Engrave for wood,bamboo,normal PCB,PVC,PMMA,plastic,duotone board(ABS)and etc nonmetal, also can engrave on gold,silver,copper, aluminium,Pb etc soft metal surface working.(Please pay more attention, this is wood working spindle, only can used for wood working and aluminum working,please don\'t use it for steel. If you need steel working,please check the metal spindle,thank you!)





Structural features :


  • High-speed electric main bearings used in all C class high-speed angular contact ball bearings, axial pre-load feature, improved support stiffness and live spindle grinding accuracy under high-speed rotation. 

  • Spindle speed according to different uses can be high-speed grease and oil mist lubrication two ways. 

  • Spindle speed rotation temperature rise caused by the use of coolant circulation system eliminated.


Prepartions before use:


  • Spindle working environment temperature is usually -10 ~ 40 .
  • Before installing the first electric spindle axis head turned by hand, should feel flexible, non-blocking phenomenon.



Use correctly:


  • Spindle in the preservation and transportation, high-speed grease inside the bearing state will change, customers should be running at low speed for 30 minutes. 3000 rpm and then follow the poor increase, run 20 minutes each. Spindle and the inverter should be working together. The inverter\'s specifications and parameter settings need match spindles parameter.

  • Connect the inverter spindle, three-phase inverter power cord should be soldered in the plug 1 (U), 2 (V), 3 (W) feet. After the power is turned on, to observe whether the spindle rotation axis indicates the direction consistent. If inconsistency should be immediately shut down, replace the inverter and spindle connected two wires of three-phase power supply.

  • It should ensure that before use of water-cooled spindle, the cooling system is working properly. Every day before using the spindle must be running at low speed for 15-20 minutes. Clamping the cutters to spindle, collet nuts ,collets,cutters must be clean enough. Shank inserted into the collet must be greater than 15mm.



Care and maintenance :


  • Spindle frequency power supply connected rated voltage, frequency should be consistent with the technical parameters of the electro-spindle, spindle speed can be adjusted to change the frequency, and voltage is proportional to the change. 

  • Spindle being not used, the application of compressed air to blow the pipes static coolant.To prevent rust, clogging water holes. Spindle appearance should be oiled. Plus the shaft protection device, put in a dry place. 

  • To replace the spindle bearings, certain professional and technical personnel should be replaced.Supporting special tools, bearings should be replaced fully cleaned without removing the stator coils.
