Grinding & Lapping

EFCO surface lapping machines are excellent for lapping individual or series components, face seals, valve seats, gates, etc.. Worn components, such as valve seats, mechanical shaft seals, disks, etc., can be re-lapped in repair workshops and at refurbishment companies. Automatic and finely adjustable lapping compound feed as well as freely adjustable lapping table speed guarantee high quality lapping results.

Portable machines for grinding and lapping of sealing faces in gate valves and non-return valves, gates and flanges. Optionally, these machines can be fitted with a digital rocker for contact pressure. This patented unit guarantees reproducibility and absolutely flat sealing faces. In addition, our valve grinding machines can be fitted with a swing-check adapter to enable machining of sealing faces on non-return valves with a large inclination. Hard seats can be machined with our portable high-speed valve grinding machine with driven spindles. This makes extremely fast and effective machining possible. This option can be retrofitted (SLA) on existing machines or can be supplied as a complete system. Fast setup and removal of the machines is guaranteed by means of a specially developed clamping block. pdf datasheet

The KS stationary grinding machines for valve and machine components can be used on site or in the workshop. They are suitable for face grinding gates, valve seats and other machine components. The aluminum grinding plate is fitted with self-adhesive abrasive disks. A fixed stop provides improved guiding of the work piece. pdf datasheet
