PRACTICAL GUIDES
Check the machine around the spindle.
Work through the interfaces and connections that determine whether a spindle suits the installation.
ATC INSTALLATION
What an ATC Spindle Needs from Your Machine
Check toolholders, mounting, cooling, VFD output and control signals before selecting an HQD ATC spindle. Compare ISO20 and BT30 installation examples.
MODEL SELECTION
How to Choose an HQD Spindle
Choose an HQD spindle by tooling, mounting, operating speed, drive and cooling. Use model examples to build a configuration-specific inquiry.
COOLING & INSTALLATION
Air-Cooled vs. Water-Cooled Spindles
Compare air-cooled and water-cooled HQD spindle installations. Check airflow, coolant connections, mounting and electrical details for the exact model.
SERIES COMPARISON
HQD GDL, GDF, GDZ and GDK Compared
Compare HQD GDL, GDF, GDZ and GDK spindle configurations. Use the series as a starting point, then check tooling, cooling, ratings and installation.
REPLACEMENT CHECKS
A Checklist for Replacing a CNC Spindle
Plan an HQD spindle replacement with nameplate, mounting, tooling, drive and connection checks. Keep configuration differences visible before ordering.
DRIVE MATCHING
Matching a VFD to an HQD Spindle
Match an HQD spindle with its VFD output, winding, current, speed and frequency. Keep duty curves and auxiliary connections separate from supply choices.
