In-Situ Machining Solutions (UK) Ltd excels in orbital machining, a service critical in preventing bearing failures on crankshafts. We employ modern techniques to repair damaged crankpin diameters and address ridge wear or "cam effect" before causing irreversible harm to the engine. Our trained on-site engineers masterfully prevent crankshaft bearing failures and correct ridge wear. Their proficiency in orbital turning, machining, grinding, superfinishing, and polishing - all carried out with our bespoke equipment - minimises engine downtime. Timely intervention on signs of cam wear significantly reduces resultant damage and crankshaft failure risks.
Identifying and Reversing Ridge Wear
Ridge wear, or Cam Wear, is an inevitable outcome of prolonged usage, particularly beyond 60,000 operational hours for medium-speed four-stroke engines. Poor maintenance and oil impurities may accelerate this process. Manifesting as a raised band around the crankpin diameter, ridge wear signals upcoming crankshaft wear and potential bearing failure. Typically affecting all big end journals on the crankshaft, this issue can be addressed via crankshaft polishing or grinding. Left untreated, it disrupts the recommended flatness for the crankpin journal surface, leading to big end failure and increasing repair costs and productivity loss. Ultimately, unchecked ridge wear can cause catastrophic bearing failures and permanent crankshaft damage and can even compromise conrods and the engine block.
