Pneumatic grinding spindle - R 4112

This spindle is ideal for fine grinding, milling and engraving surfaces that must not be oil lubricated. The centrifugal governor ensures constant speed and reduces air consumption.

This deflectable pneumatic spindle is capable of compensating part and positioning tolerances when machining. This means that it is possible to trace a part contour with constant pressure and achieve uniform removal, even under fluctuating conditions. An optimum application for this system is, for example, the automated deburring of castings or machined components using an industrial robot. Adaptor flange (Order no. 003 012 557) to simplify the mounting of the system is available directly from us. The deflection force is individually infinitely adjustable using air pressure (2-6 bar), even during processing. This enables the removal rate to be perfectly adapted to the thickness of the burr. After deflection the pressurized air piston always returns the tool to the zero position against a positive stop. Hysteresis zero.

The lubricant-free drive of this grinding spindle based on a vane motor is unique and patented. Its great advantage: It provides the high performance of a vane motor and can still work completely lubrication-free. This model includes the BIAX hose unit with silencer.

This spindle is designed to be very compact, yet it is equipped with a powerful Motor for grinding and milling. Also available: Splash guard and spindle with counterclockwise rotation.
