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!)
Bearing is P4 grade,2×7005C P4 DT & 2×7002C,increase the spindle life.
High speed,high torque,low noise,low price.
High precision,run out off less than 0.01mm. Coaxial degree less than 0.0025mm
We are the spindle manufacturer,we offer only best quality and best price to 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.
1. Our Ceramic ball bearings spindle use 4 pcs ceramic ball bearings.
2. Ceramic ball bearings are resistant to high temperatures and low heat, usually 3-5 degrees lower than steel ball bearings during using .
3. Ceramic ball bearings have low 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. 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.
If the spindle will not be used for a long time, please keep the spindle oil sealed to prevent rust from being unused for a long time.
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.
Spindle frequency power supply connected rated voltage, frequency should be consistent with the technicalparameters 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.
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.
