Some recent in-situ machining for a valued mining client. The trackframe mounting pads of a CAT excavator were extremely worn and corroded. The four pads were cleaned up, pad welded and machined back to original OEM spec. The solid 2 metre 3 axis portable milling machine in conjunction with a high precision laser ensured that correct positioning, flatness and height of mounting pads were acheived as well as hitting parallel and squareness tolerances. It's always pleasing to complete a project like this without hitch and ahead of schedule.
