Technical FAQ & Operational Guide

What is the maximum permissible speed for the A2-3 Lathe Spindle?

This standard spindle is designed and balanced for high-speed precision turning up to 6000 RPM.

Which bearings are used in the front and rear assemblies?

It features a high-rigidity setup with three 7011 P4 bearings in the front and two 7010 P4 bearings in the rear.

Is external lubrication required for this spindle?

No, this spindle comes grease-packed from the factory, offering a low-maintenance solution for industrial environments.

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.
