The NEW mobile HUNGER UDM4E Universal Lathe is a versatile lathe with modular components for refinishing valve and valve seat surfaces, as well as for boring seat ring holes and facing sealing surfaces on cylinder heads, liners, and engine blocks of large diesel and gas engines.
Advantages:
- No
- dustNo noise
- Compact and mobileFast processing
- Low voltage to avoid electrical hazards
Our VKM valve grinding machines are used for grinding valves with stem diameters from 6 to 40mm.
Valve seats are turned using our VDS2E, VDS2.3E/2.5HD, and VD4HD valve seat lathes.
Advantages:
- Extremely short processing time
- No grinding dust
- Compact and handy
- Easy to operate
- Operation with safety extra-low voltage

and in the workshop
With the VD4HD-ADM boring machine, valve seat ring holes in the cylinder head can be bored for the installation of oversize seat rings.
With the VD4HD/-30° cone turning machine, the conical surface on the valve cage can be reconditioned.
With the PHM and SHM pneumatic honing machines, cylinder liners of large diesel engines up to a diameter of 640mm can be honed.
The compressed air-operated high-pressure hydraulic unit serves as a mobile drive unit for hydraulic tools, especially for tools used for tightening and loosening tension joints on large diesel engines.
On the NTS nozzle test stand, injection nozzles of large diesel engines can be tested and, if necessary, maintained.
The shape and degree of atomization of the injected test fluid and the tightness of the needle seat are checked.
On the extremely robustly built WV assembly stand, heavy cylinder heads of large diesel engines can be clamped securely and easily for maintenance and reconditioning work.

Product Range Automotive
Our VKM1M valve grinding machine is used for grinding valves with a stem diameter of 6 to 20mm.
With the hand-operated VD valve seat turning devices, valve seats of engines are reconditioned using the fine turning process.
With the RDS turning device, the base hole provided in the cylinder head for receiving a valve seat ring can be bored.
With the BDW liner seat turning device, the seat provided in the engine block for receiving the cylinder liner flange can be faced.
The test device, connected to compressed air (approx. 6 bar), generates a vacuum when the trigger button is pressed, which is applied to the intake or exhaust port of the valve being tested using an adapter plate.
The pressure gauge on the test device indicates the level of vacuum.
If the gauge reading is in the green zone, the valve is tight.
