Technical FAQ & Operational Guide

Can this motor be used for metal cutting?

Yes, it is highly efficient for soft metals such as aluminum, brass, and copper. The 24,000 RPM speed and stable 1.27 Nm torque provide the precision needed for clean metal milling.

What is the benefit of the water-cooling system for stone carving?

Stone and marble carving are heat-intensive processes. Water cooling ensures the motor maintains a stable operating temperature, preventing thermal expansion and protecting the internal bearings from premature wear.

How do I configure the dual-voltage settings?

The voltage configuration depends on your Variable Frequency Drive (VFD) setup. This spindle can be run on either 220V or 380V; please ensure your VFD parameters are matched to the motor nameplate to prevent damage.

How is the rotational balancing calibrated on this spindle motor?

Every spindle motor is dynamically balanced in accordance with the ISO 1940 balancing standard to guarantee vibration-free running and maximum stability at high RPMs.

What are the runout tolerances of the shaft and collet interface?

The internal shaft taper maintains a runout accuracy tolerance of under 0.003mm (3 microns), maintaining precise tool concentricity and preventing premature cutter wear.

What cooling precautions are built-in to prevent heat exhaustion?

Built-in temperature dissipation channels support continuous water/liquid cooling circulation or forced fan airflow, preventing thermal expansion of components.

Is this spindle motor compatible with standard VFD inverters and collets?

Yes, the spindle supports direct electrical integration with standard variable frequency drives (VFD) and accepts industrial ER collets (ER11, ER20, ER25, or ER32) to match standard toolholder dimensions.
