1X 3.2KW ER20CNC Water Cooled Spindle Motor 100x250mmSize:100x250mm(Middle body diameter:100mmxLength:250mm)Speed Ways:Through 3-phase output inverter and adjust the inverter to change the spindle speed.Cooling:Water coolingPower Interface:Optional H20-4 pinswaterproof air. Theair marked "1 ","2"," 3","4", "1 ","2 ","3" were connected to inverter(U, V, W), 4 connected inverter ground.Power:3.0kwVoltage:220v / 380vCurrent:15A / 8A0-400HzSpeed:0-24000rpmRunout Off:Less than 0.01mmDiameter(mm):100Bearing Type:2 x7005 P4 DT & 2 x 7003 P4 DT4pcs bearingsColletER20Clip Knifediameter13mm12mm12.7mm,11mm,10mm,9mm,8mm,7mm, 6.35mm,6mm, 5mm, 4mm, 3.175mm, 3mm, 2mm, 1mm(standard 6mm)Water Cooling ER20 collet chunkGrease LubricationMain Application:Engrave for wood,bamboo,normal PCB,PVC,PMMA,plastic,bamboo,duotone board(ABS)and etc nonmetal,also can engrave on gold,silver,copper,aluminium,Pb etc soft metal surface working.P4 fully sealed angular contact bearings ,2 x 7005 P4 DT & 2 x 7003 P4 DT increase spindle life Longer length make the torque biggermore powerful Carefull assembly make the spindle more precisional Precision 001mmCoaxial degree less than 00025mm. Pay attention: The spindle size is 100x250mm mm, bigger torque.There are 4 labyrinth seal in the front section of the spindle,Prevents lubricant leakage from bearings and intrusion of harmful impurities (dust, moisture, corrosive gases) and bearing seals under high-speed conditions.1.Our Ceramic ball bearings spindle use4 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 .-2hours. 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 need match spindles parameter..Connect the inverter spindle, three-phase inverter power cord should be soldered in the 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..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..Water cooled spindleMUSTbe used with water pump. Otherwise the spindle will soon broken..AC spindle motorMUSTuse with inverter. The power of inverter need equal or bigger than the spindle power. Before using,please set up the inverter parameters suitable for spindle. Otherwise the spindle and inverter will broken at once..When you use the spindle,the noise is not same as always,pleaseSTOPthe spindle at once. You may need to replace the spindle bearings.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.Origin : Mainland ChinaDrive : MotorMaximum Torque : 1.27N.mOperating Speed : 0-24000rpmModel Number : 3.2kw water cooled spindle motorApplication : MillingSize : 100X250mmVoltage : 220v/ 380vCurrent : 15A/8APower : 3.2kw (1HP=735w)Cooling : Water cooledBearing Type : 2 X 7005C P4 DT and 2X 7003C P4 DTCollet : ER20400HzLubrication : GreaseCollet Range : 1-13mm (Including 1/4,1/8,1/2)
