CNC Spindle Motor 3.5 kW, 18000 RPM, 300Hz Dual-Head Air-Cooled ER20 - CNC Spindle Motor

CNC Spindle Motor 3.5 kW, 18000 RPM, 300Hz Dual-Head Air-Cooled ER20

The 3.5 kW Dual-Head Air-Cooled Spindle Motor is a specialized industrial solution designed for CNC applications that require multi-tool versatility or simultaneous machining capabilities. Delivering 3.5 kW of robust power at a peak speed of 18,000 RPM, this motor features a unique dual-axis architecture that allows for the mounting of tools on both ends of the spindle body. This configuration is ideal for complex woodworking and routing tasks, reducing the need for manual tool changes and increasing production throughput. Operating at a stable 300 Hz frequency, the spindle utilizes an advanced dual air-cooling system to ensure efficient heat dissipation across both heads during intensive operations. Equipped with precision ER20 collet interfaces on both sides, this spindle provides secure tool holding and the mechanical rigidity necessary for high-speed precision machining.

Technical FAQ & Operational Guide

What is the primary benefit of a Dual-Head spindle?

A dual-head spindle allows you to mount two different tools simultaneously (one on each end). This is extremely beneficial for processes that require two distinct operations—like roughing and finishing—without needing a full tool changer or stopping the machine to switch bits manually.

Does the 18,000 RPM apply to both heads?

Yes, both heads are driven by the same internal motor, meaning they rotate at the same speed (up to 18,000 RPM) and frequency (300 Hz) simultaneously.

Is the cooling sufficient for both heads?

Absolutely. This model features a specialized 'Dual Air Cooling' system specifically designed to push high-velocity air across the entire motor housing, ensuring that both bearing sets and the central windings remain within safe operating temperatures during continuous use.
