ABSTRACT:
An idler or tensioning assembly for an electronically controlled sanding/polishing machine is provided, the sanding/polishing machine utilizing a plurality of exchangeable polishing wheel assemblies of which the idler assembly is one. Each polishing wheel assembly interfaces with the sanding/polishing machine through a coolant manifold and a polishing wheel shaft receptor. The idler assembly is operative to provide releasable tension to a sanding/polishing belt that is situated around the idler and the associated sanding/polishing wheel. The idler assembly has a pivoting idler that is actuated by a hydraulic cylinder. The hydraulic cylinder utilizes coolant tapped from the coolant manifold of the idler assembly for actuation. Coolant is provided to the hydraulic cylinder in response to a valve signal. The idler assembly thus has a tensioned mode and an untensioned mode.
