Pneumatic triple action Bigfoot polisher with 75mm pad and 15mm orbit

LTA75

Rupes Pneumatic triple action Bigfoot polisher is offering a new type of movement known as TRIPLE ACTION. The power of a motor can be expressed as the product of the torque multiplied by the velocity. During normal use of a tool, the operator applies a variable load, which by effect of the friction forces and the work carried out by the motor might be such as to reduce the number of revolutions of the motor and, in the case of a DA random orbital, is such as to reduce the number of disc revolutions to zero.

The load applied by the operator during normal use of a tool varies significantly over a measure of time, causing large variations in velocity of the number of orbits and the rotation of the rotor disc and consequently reducing the uniformity and effectiveness of the work operation. A more homogeneous process leads to a significant reduction in working times. In the case of triple action tools, and similar to the movement of DA random orbital tools, the disc, typically circular, follows an orbit and is free to rotate about its own central axis but, thanks to a special epicyclic gear reducer located in front of the cam group, the torque value is significantly increased while at the same time the velocity is reduced.

Pneumatic triple action Bigfoot polisher with the use of this solution the impact of a variable in performance (the load applied by the user) is substantially minimized and, consequently, a greater uniformity of performance of the tool. This provides a considerable improvement in the surface finish as well as a drastic reduction in the vibration levels. From the very first use it is clear how advantageous this configuration is in terms of effectiveness and vibration reduction all thanks to the introduction of the epicyclic gear reducer; this is a technical improvement that so profoundly improves and changes the functionality of the tool that it merits a new movement category, the TRIPLE ACTION.
