INSTALLATION CHECKS
Match the whole assembly.
Start with the exact GDK105-9-21Z/2.2-5.0 configuration. Compare the mounting drawing, nose clearance and connection locations with the existing installation. Check the collet, nut clearance and usable clamp area before reusing tooling or supports.
- Check the water circuit and the connector details shown in the drawing.
- Ask for the voltage and current of the supplied spindle before choosing the drive. Do not use another model’s electrical ratings.
