CNC Spindle Motor 1.2 kW, 40,000 RPM, 220V High Speed Water Cooled
The 1.2 kW Water-Cooled CNC Spindle Motor is a specialized high-speed solution engineered for applications requiring exceptional rotational velocity and fine-detail accuracy. Delivering a robust 1.2 kW output at a peak speed of 40,000 RPM, this motor is specifically designed for intricate CNC bangle making and high-density PCB drilling. Driven by a 666 Hz frequency, the spindle provides a consistent 0.42 N.m of torque, ensuring vibration-free operation even at extreme speeds. The precision internal architecture utilizes a 4-bearing P4 configuration—featuring two 7002 P4 bearings at the front and two 7000 P4 bearings at the rear—to maintain micron-level runout accuracy. Its integrated water-cooling jacket provides critical thermal management, protecting these high-speed bearings during continuous industrial duty cycles. Equipped with a versatile ER11 collet system, this 4 kg motor is the ideal choice for jewelry manufacturers and electronics fabricators requiring a compact, high-velocity spindle for delicate machining environments.
