Specification Brand : Generic BulletPoint1 : ►[Spindle Motor]----water-cooled spindle diameter: 105*265mm/4.13*10.4in, power: 3.2KW, voltage: 220V, frequency: 400Hz, current: 12A, speed: 24000RPM, chuck: ER20, bearing: 4 bearings (7005C P4*2; 7003C P4*2), runout tolerance: less than 0.005mm. Note: The water-cooled spindle must be used with a frequency converter and a water pump, and the frequency converter voltage must be consistent with the spindle. BulletPoint2 : ►[Cooling method]----This CNC spindle motor adopts water circulation cooling. The coolant water volume is calculated at 2.5 liters/kilowatt-minute, and the coolant flow rate is 3 to 6 liters/minute. The high temperature generated by the high-speed rotation of the spindle is reduced by water circulation, so that the spindle rotor and bearing temperature are always kept at 10~40℃. Note: The coolant should be replaced regularly every month; the temperature of the coolant should be 3-5℃ lower than BulletPoint3 : ►[ER20 Collet]----ER20 chuck is quenched with manganese steel, with high precision and good stability. ER20 clamping range: 1.5-13mm, wide clamping range, can meet the needs of various precision machining. BulletPoint4 : ►[4 bearing design]----This CNC spindle motor adopts 4 precision steel ball bearings (7005C P4*2; 7003C P4*2), with high precision, stable performance, excellent anti-rust performance, and ensure the rotation accuracy of the spindle during high-speed grinding. BulletPoint5 : ►[Maintenance and Care]---- 1. When the electric spindle is running, if the sound or vibration is abnormal, the bearing should be stopped immediately to check the bearing, and new bearings should be replaced if necessary. When an abnormal odor is emitted during operation or it stops suddenly, the power supply should be cut off immediately, and the stator resistance to ground and three-phase resistance should be measured with an ohmmeter. The loss of insulation resistance means that the stator Color : One Color ItemName : 3.2KW 220V ER20 400HZ 105 * 265mm Water-cooled Spindle Motor Kit, High Speed 24000RPM 4 Bearings For CNC Stone Engraving ItemPackageDimensions_Height : 30 centimeters ItemPackageDimensions_Length : 50 centimeters ItemPackageDimensions_Width : 30 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : power-milling-machines Manufacturer : Generic Material : Metal ModelName : FDECHJBGF ModelNumber : FDECHJBGF NumberOfBoxes : 1 NumberOfItems : 1 PartNumber : FDECHJBGF ProductDescription : Description:
Instructions for use:
1. Connect the inlet and outlet water pipe joints of the electric spindle as required, and check whether the connection is leaking and unobstructed. The cooling system of the water-cooled electric spindle should be connected to the main switch of the machine tool; the cooling system should work continuously from the start to the shutdown. The water volume of the coolant is calculated at 2.5 liters/kilowatt-minute, and the coolant flow rate is 3 to 6 liters/minute. The small electric spindle takes the smaller value and the large electric spindle takes the larger value; the coolant requires a separate water tank and the coolant requires regular replacement every month; the temperature of the coolant should be 3 to 5°C lower than the ambient temperature, preferably controlled at around 25°C. 2. The selected frequency converter should match the voltage, power and frequency of the electric spindle for matching use. To set the inverter, first set the base frequency of the inverter. The base frequency of the inverter is set according to the highest frequency of the electric spindle. 3. Connect the inverter to the three-phase power supply of the electric spindle. The three-phase power supply line of the inverter should be welded to the plug 1 (U1), 2 (V1), 3 (W1) pins, and the 4th pin is the ground wire. Then connect the inverter to the external power supply. After the power is turned on, the inverter jogs to observe whether the rotation direction of the electric spindle is consistent with the indicated direction of the electric spindle. If the rotation direction is inconsistent, the machine should be shut down and corrected immediately. The electric spindle is strictly prohibited from running in the wrong rotation direction. The connection between the electric spindle and the inverter should not exceed 25m. 4.
