What is the advantage of a square body design for a 7.5kW spindle?

The square body provides a larger, flatter mounting surface than round spindles. This significantly improves the mechanical connection to the machine headstock, reducing vibration during heavy-duty cutting and ensuring a superior surface finish.

Is any external cooling needed for this motor?

No, this model is fully air-cooled. It features a built-in fan system designed to maintain an optimal operating temperature, making it a lower-maintenance alternative to water-cooled models in industrial environments.

Which tools can I use with the ER32 collet?

The ER32 system is a standard industrial interface that supports tool shanks from 2mm up to 20mm. This versatility allows you to use everything from fine engraving bits to large material removal cutters.
