CNC Spindle Motor 6.0 kW, 18000 RPM, 380 V Aircooled Square

The 6.0 kW Square Air-Cooled Spindle Motor is engineered for industrial-grade CNC machining where power and thermal stability are paramount. Running at 18,000 RPM with a 380V 3-phase input, this spindle is a primary choice for high-speed CNC routers, foam profiling, and heavy wood relief carving. The square body design provides a stable and rigid mounting surface, significantly reducing vibration during deep cuts. Built with a premium P4 bearing arrangement (7008 and 7002 series), it ensures extreme rotational accuracy and long service life. The integrated fan cooling system allows for efficient heat dissipation during continuous high-speed production cycles.

Technical FAQ & Operational Guide

What is the benefit of the square body on this 6.0 kW motor?

The square body allows for more rigid and secure mounting to the machine's Z-axis plate. This stability is crucial for maintaining accuracy during high-speed, heavy-duty cuts.

Does this spindle require a special VFD?

Yes, it requires a 380V 3-phase Variable Frequency Drive (VFD) capable of handling at least 6.0 kW and a frequency of up to 300 Hz.

What size collet does this spindle use?

It uses an ER32 collet system, which is very versatile and can hold tool shanks ranging from 2mm up to 20mm in diameter.

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.
