ABRASIVE WEAR TESTING MACHINE WITH CYCLE PROGRAMMABILITY AND VARIABLE FORCE APPLICATION

摘要

An abrasive wear testing machine exhibiting a support surface upon which is dynamically supported a tray to which a wear piece is secured. A tool bit is supported by a vertically displaceable and weight supporting bracket in a fixed and downward load applied fashion against the wear piece, such that the tray is reciprocated a selected number of cycles to determine a wear profile exerted upon the wear piece by the tool bit. The bracket is configured so that end located receiving channels are each seatingly engaged upon upwardly extending hydraulic lifts secured to the support surface, with a plurality of free weights arranged upon the hydraulic lifts.
