  • Water Cooling ER20 collet chunk

  • 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!)

  • 4 P4 angular contact bearings,2×7005C P4 DT&2×7002C P4 DT,increase spindle life

  • ER20 collet nut,you can use ER20 collet kits for it.

  • Carefull assembly make the spindle more precisional.

  • Runout off 0.01mm.Coaxial degree less than 0.0025mm.

  • Better appearance, after a long time using,still looks like new.

  • We are the spindle manufacturer,we offer only best quality and best price to you.

1. Our Ceramic ball bearings spindle use 4 pcs ceramic ball bearings.

2. Ceramic ball bearings areresistant to high temperatures and low heat, usually 3-5 degrees lower than steel ball bearings during using .

3. Ceramic ball bearings havelow friction, low noise and long service life.

4. If you want to use the spindle for aluminum, hard wood, then ceramic ball bearings better than steel ball bearings.

  • 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.

  • 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, 4 feet for the ground. 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.

  • During normal operation, air-cooled spindle often encounter the phenomenon of heat, always check whether the air-cooled spindle housing and duct clogging dust.If clogging dust, to promptly clean up. If you do not clean up, it is easily to make the spindle burned.

  • 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.

  • 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.

Before shipping , we did the oil seal to avoid the rust during the long shipment. When you get the spindle, please clearing the oil seal before using. Thank you.

1. Cooling in different ways: water-cooled spindle motor is the use of the water cycle to cool the heat generated after the high-speed rotating spindle, spindle motor with fan-cooled approach to cooling.

2. Noise: Water-cooled spindle motor is basically no noise, but the air-cooled spindle motor is very loud.

3. Life aspects: Water-cooled spindle motor pay attention to maintenance, frequently changes the water or the use of industrial water coolers, air-cooled spindle fan mainly by the wind blowing the heat transferred to the heat sink, so as to achieve the cooling effect.

4.If you need use for metal ,hard wood,granite,stone,you can choose metal spindle.Metal spindle much better than wood spindle.

  • Spindle from the production - assembly - test, and finally the perfect packaging . 

  • We will 100% guarantee security to the hands of the guests.
