1:5 Ratio

BENZ Spindle Speeders are designed for the most demanding machining environments where the tool is a critical part of the production process. 

All standard Benz Spindle Speeders have a 1:5 ratio and maximum speed of 40,000RPM and are equipped with jacket cooling as standard, which supports an internal coolant supply of up to 100 bar. Special bearings and sealing technologies ensure low heat generation and guarantees dimensional accuracy for longer machining cycles. The high running smoothness and concentricity, in combination with maximum spindle rigidity and low heat generation, makes any spindle suitable for a wide range of applications for drilling and light milling operations.
