MXBAOHENG CNC Spindle Motor with 4 Bearings, 2M Aviation Wires, Water Cooled, 220V, CNC Spindle for CNC Router Engraver Milling Machine (2.2, Kilowatts)

This CNC spindle is specifically designed for upgrading desktop-level CNC equipment and for small-scale machining scenarios. It serves as a core component that balances power, precision, and practicality. This spindle eliminates the need for industrial high-voltage circuits and can be directly adapted for home use or small studios. When paired with a 220V VFD frequency converter, it achieves stepless speed regulation from 0 to 24,000 RPM. With precise speed response and ample torque, it effortlessly handles engraving, milling, and drilling processes for various materials such as wood, aluminum, plastic, and stone. Compared to traditional handheld routers, it significantly enhances processing efficiency and efficiently completes complex curved surfaces and fine structures. This water-cooled spindle, paired with a cooling water pump, can quickly reduce the heat generated by high-speed rotation, ensuring that the spindle maintains a stable temperature below 40℃ even during prolonged continuous operation. The machine body is equipped with 4 upgraded bearings, with radial and axial runout controlled within 0.02mm. This not only enhances the spindle rigidity and operational stability, reduces cutting chatter, but also reduces tool wear and ensures smooth machined surfaces. The spindle is compatible with 220V VFD inverters, featuring clear wiring labels for easy installation even by novices. Equipped with aviation plugs and a 2m(78.74’’) connecting cable, it can be quickly put into use right out of the box. Whether it's for upgrading and replacing CNC equipment or building custom machine tools, it is the preferred choice for both cost-effectiveness and reliability. Note: This link does not include any frequency converters or cooling water pumps. If you need them, please purchase them separately.

• 【2M Aviation Wire】The spindle is equipped with a 2M(78.74’’) extended aviation plug connection cable, which is long enough to fit most CNC equipment layouts without requiring additional wiring extensions. The wiring is clearly labeled, making it easy for novices to quickly complete the connection.
• 【4 Bearings】The machine body is equipped with 4 upgraded bearings, which have undergone professional dynamic balancing calibration. The radial runout is controlled within 0.02mm, significantly enhancing the spindle rigidity and operational stability, reducing chatter and tool wear during the cutting process, and ensuring the smoothness and precision of the machined surface.
• 【Water Cooling】The water-cooled spindle can quickly reduce the heat generated by high-speed rotation, ensuring stable and controllable continuous working temperature of the spindle. This avoids accuracy deviations caused by thermal deformation and extends the service life of bearings and motors. Compared to air-cooled spindles, it has lower noise and stronger stability.
• 【Wide Application】This spindle does not require industrial high-voltage circuits and can be directly used in homes or small studios; it supports stepless speed regulation from 0-24000RPM, with stable torque output, enabling efficient engraving, milling, and drilling operations for materials such as wood, aluminum, plastic, and stone.
