Cylinder Heads

We offer machines for Grinding & Machining of cylinder heads on both 2-stroke and 4-stroke diesel and gas engines. They take care of overhaul and restoration of valves, valve seats, valve spindles and seat recesses. Some of them are electrically driven while others are pneumatically driven. We also have a machine that easily removes valve seats.

Cylinder Liners

Our large range of Grinding & Machining equipment for restoration and overhaul of 2-stroke and 4-stroke cylinder liners includes honing & deglazing machines, as well as machines for wavecut grinding and wear edge milling. In addition, we offer a Unistress piston ring expander and honing rigs for liners with an outer diameter of 200 to 800 mm.

Sealing Surfaces

Our Grinding & Machining equipment for sealing surfaces consists of machines that can handle grinding on top of engine frames, between cylinder head and cylinder liner as well as between cylinder liner and engine frame. Some machines are pneumatically driven and others electrically driven. They are all suitable for both 2-stroke and 4-stroke engines.
