Installation & Maintenance Tips
- Clean the spindle: Remove debris and oil before mounting the mandrel.
- Align the mandrel: Use a dial indicator to verify concentricity within 0.02 mm.
- Set expansion: Adjust the expansion screw to the required tolerance, then lock in place.
- Inspect regularly: Check for wear on the carbide surface and replace the mandrel if cracks appear.
- Lubricate sparingly: Use high‑temperature spindle oil only on moving threads to avoid contamination.
Frequently Asked Questions
Can the 749014408 be used with non‑carbide tools?
Yes, the mandrel’s expansion mechanism works with both carbide and high‑speed steel tools, provided the tool shank matches the mandrel’s diameter.
What is the recommended maximum spindle speed?
The mandrel is rated for up to 12,000 rpm. Exceeding this speed may reduce service life.
How often should the mandrel be inspected?
For high‑volume production, inspect after every 200 hours of operation or after any incident of tool breakage.
Is the mandrel compatible with automatic tool changers?
Yes, it is designed to integrate seamlessly with most ATC systems that support standard 16 mm shank tools.
