Pneumatic grinding spindle - R 3030

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.

The coupling The coupling is the heart of the system and is always part of the equipment. It receives the spindle packages and combines them with a connection or deflection. The coupling also enables the system to be supplied with compressed air from the side. The deflection Depending on the application, the system can be made rigid or radially deflected. The deflection unit is mounted in only a few steps between the coupling and connection and immediately converts the rigid system to a flexible system. The deflection force can be adjusted using the adjusting ring between approximately 15 and 120 Newton. The attachments We have the perfect attachments in our programme for many applications. For the machining centres we offer the standard machine tools attachments such as HSK and SK and a Weldon adapter. These mountings also enable compressed air supply through the coolant channel. Universal adapters are available for stationary mounting or mounting to a robot.
