RUPES triple-action polishing machine Bigfoot ø 125mm stroke 12mm

The Rupes pneumatic triple polisher offers a new type of motion known as TRIPLE ACTION. The power of a motor can be expressed as the product of torque multiplied by speed. During normal use of a tool, the operator exerts a variable load, which, due to frictional forces and the work performed by the motor, can reduce the number of revolutions of the motor and, in the case of a DA Random Orbital, to reduce the number of disc revolutions to zero.

The load applied by the operator during normal use of a tool varies considerably over time, resulting in large fluctuations in the speed of the number of orbits and the rotation of the rotor disc, consequently reducing the uniformity and effectiveness of the work process. A more homogeneous process results in a significant reduction in working times. In triple-action tools, and similar to the movement of DA tools with random orbit, the disc, typically circular, follows an orbit and can rotate freely around its own central axis. However, thanks to a special epicyclic reduction gear at the front of the cam group, the torque value is significantly increased while simultaneously reducing the speed.

In the pneumatic triple-action polisher, using this solution significantly minimizes the influence of a power variable (the load applied by the user), resulting in greater uniformity in the tool's performance. This results in a significant improvement in surface finish and a drastic reduction in vibration levels. Even upon first use, the advantages of this configuration in terms of efficiency and vibration reduction are clear, thanks to the introduction of the epicyclic gear. This is a technical improvement that improves and transforms the tool's functionality so profoundly that it merits a new motion category: TRIPLE ACTION.
