Technical FAQ & Operational Guide
Why is the 12 Nm torque important for this model?
Torque is critical for heavy material removal. A 12 Nm rating ensures the spindle can push through dense materials like steel, granite, or hardwood without stalling at lower RPMs, which is essential for die molding and stone carving.
What are the advantages of the BT40 tool holder?
BT40 is a world-standard industrial interface. It provides massive clamping strength and rigidity, which allows you to use larger milling bits and face mills that would be impossible on smaller collet-based spindles.
Does this spindle require a chiller for cooling?
Yes, for a 7.5 kW motor performing heavy-duty industrial tasks, we strongly recommend a dedicated water chiller to maintain a constant temperature and protect the internal precision components.
