Specification
Brand : Generic
BulletPoint1 : Spindle parameters: Specifications: φ3.94 x 11.8 inches/100*300mm; Power: 4.5 kW; Voltage: 380V; Current: 16A; Chuck size: ER20 Ø3.175~Ø13; Bearings: 4 bearings (7005C/P4*2, 7003C/P4*2); Frequency: 400hz; Speed: 24000RPM; Runout: less than 0.005mm. CNC spindle motors are mainly used in engraving machines or in conjunction with frequency converters.
BulletPoint2 : ER20 standard collet: The CNC spindle chuck is quenched with manganese steel, with a runout of less than 0.005 mm, high precision, not easy to break the knife, and increases the stability of the working process. Dynamic balancing technology can effectively reduce noise during use.
BulletPoint3 : Cooling method: Our spindle motor mainly uses a water pump to push the cooling water to circulate inside. After the cooling water absorbs the heat generated by the high-speed operation of the spindle motor, it flows through the radiator and dissipates the heat into the air, thereby achieving a rapid cooling effect.
BulletPoint4 : High-quality materials: Our water-cooled spindle body is made of high-quality stainless steel, anodized surface, equipped with pure copper rotor to ensure high-quality processing and engraving performance, the spindle built-in dust cover design prevents dust from entering the body. The upgraded 4-hole aviation plug ensures the stability and safety of the input power.
BulletPoint5 : Multiple applications: This water-cooled spindle motor is often used for engraving and cutting materials such as stone and metal. It is suitable for many fields such as machinery manufacturing, sheet metal processing, guardrails, factories, shipyards, home decoration, construction, etc.

ProductDescription : ●During the storage and use of the spindle, the internal bearing condition of the high-speed grease will change. It should be operated at low speed for 30 minutes first, and then slowly increased to 3000 rpm, and operated for 20 minutes each time. The spindle and the inverter should work together. The specifications and parameter settings of the inverter match the spindle parameters.
●When connecting the inverter spindle, the three-phase inverter power cord should be welded to the plug 1 (U), 2 (V), 3 (W) pins and the ground pin 4. After power on, observe whether the spindle rotation axis always indicates the direction. If not, shut down immediately and replace the inverter and the two three-phase power cords connected to the spindle.
●Before using the spindle every day, the spindle must be operated at low speed for 15-20 minutes, and the tool must be clamped on the spindle. The chuck nut, chuck, and tool must be clean enough, and the tool handle must be inserted into the chuck more than 15mm.
●The water-cooled spindle must be used with a water pump, otherwise the spindle will break down quickly.
●The AC spindle motor must be used with the inverter, and the inverter power must be equal to or greater than the spindle power. Please set the inverter parameters suitable for the spindle before use, otherwise the spindle and inverter will break down immediately.
●When using the spindle, the noise is different from before, please stop the spindle immediately, and the spindle bearing needs to be replaced.

Speed regulation mode: Through the three-phase output inverter and adjust the frequency of the inverter to change the spindle speed.
Power interface: optional 4 pin waterproof air plug. The air plugs marked "1", "2", "3", "4", "1", "2", "3" are connected to the inverter (U, V, W), 4 are connected to the inverter The device is grounded.
