Frequently Asked Questions
What is cylinder liner honing?
Honing is a precision machining process that refines the surface finish of a cylinder liner bore after boring or repair work. It creates the correct cross-hatch pattern for optimal oil retention and piston ring seating.
What liner diameters can you hone?
Our honing machine handles cylinder liner diameters from 150mm to 400mm, covering the majority of engines in the 100KW to 18MW power generation range.
How is surface finish quality verified?
We use a dedicated roughness tester to measure the finished surface profile and confirm it meets the manufacturer's specified roughness parameters before returning the engine to service.
Can this service be performed on-site?
Yes. Our honing equipment is portable and our team performs all work in-situ at your facility, avoiding the cost and risk of engine removal and transport.
