As part of our service facility and a most important part of our re-manufacturing process, we have three lapping machines which are capable of lapping all flat components i.e valve seats, discs, mechanical seals and any flat objects to within 1 light band of flatness.
Each lapping table is checked routinely using test gauges and a monochromatic light to keep the lapping surface to within 1 light band of flatness thus ensuring accurate lapping of all components.
