Advantages - Very short refacing time! - No dust! - No noise! - Powered by low operating voltage! Features The machine is fitted with two motors providing a smooth cutting action. The operating voltage supplied to the motors by a compact power supply unit is of the low voltage type to eliminate electric hazards. The exchangeable adapter head with the built-in slideway for cutting tool travel ensures a precise seat angle eliminating faulty setting operations. Roundness, concentricity and surface finish of the refaced valve seat are within manufacturers’ specifications or even better. Handling Setup is fast and easy. First, lock the pilot with mounted centering spider in the valve guide. Then, lower the machine over the pilot and position the cutting tool in front of the inner edge of the valve seat. Turn micrometer downfeed to set the desired depth of cut. Refacing is automatic. Pressing one button is enough to start the refacing pass.

Application The VD4HD-RC is designed for refacing • the landing surface for the cylinder liner on the engine block, • the landing surface for the cylinder head on the cylinder liner and • the landing surface for the cylinder liner on the cylinder head. Features Drive unit and gear head of the VD4HD-RC are identical with the drive unit and gear head of the VD4HD Valve Seat Refacing Machine. If you have already a VD4E machine and you want to use it with our new face turning heads, we can convert it into the new high performance VD4HD System. The three available face turning heads should be used according to our recommendation with the VD4HD drive unit and the related power supply type 4HD. We would be glad to advise you about our new VD4HD system and send you an offer for this. The D4/0° adapter head is bolted to the gear head in place of the valve seat refacing head. The VD4HD-RC is centered by a pilot assembly which is designed to fit to the engine component to be serviced.

The new portable HUNGER universal refacing machine UDM4E is a versatile machine offering a choice of modular components for refacing valves and valve seats as well as counterboring seat ring pockets and resurfacing the sealing surfaces on cylinder heads, cylinder liners and engine blocks of large diesel and gas engines. Key features: - No abrasive dust. A fast clean cut, - Compact and handy design - Modular add-on components provide a flexible solution for multiple projects - Powered by SELV (Safety Extra Low Voltage) to avoid risk of electrical shock - Power supply with universal AC input - Fast set-up time - Easy to use - The economical solution for both field and workshop use »Roundness, concentricity and surface finish of the refaced faces are within manufacturers’ specifications or even better«

Working Principle: The counterbore is machined to the preset depth by the simultaneous application of both a rotary and vertical or horizontal feed motion to the carbide cutting insert. While the cutting insert rotates in a circle around the counterbore, a feed gear mechanism ensures a continuous feed motion. The lathe-type refacing action provides smooth and closely fitting contact surfaces for oversize valve seat rings. Features: The motor drive unit of the VD4HD-ADM is identical with the motor drive unit of the VD4HD Valve Seat Refacing Machine and, therefore, is only required, if no VD4HD is at hand. Two types of exchangeable boring gear heads are available. The standard AV boring head is provided with a vertical slide for counterboring. The optional AVH boring and facing head is provided with a vertical and a horizontal slide for counterboring and facing the bottom of the bore.

The customer range of our milled parts stretches from medical and furniture technology to classical mechanical engineering.

We manufacture turned parts such as threaded bushings and nuts for mechanical engineering, power plant technology and for furniture technology. The treatment of the turned parts takes place on our CNC turning machines, conventional lathes, 6-spindle multispindles or automatic lathes. Threaded bushings and thread nuts are usually supplied as a system with matching stems (spindles).

A stem or spindle with a trapezoidal thread is normally used as a movement stem (spindle). We manufacture stems (spindles) from Tr 12 to Tr 110 for drive and actuator technology, for valve construction as well as for power plant, water, waste water and theater technology.

Hollow stems (spindles) are pipes with an external thread over the entire length of the tube. They are used for example in telescopic drives for high-quality furniture.

Threaded stems (spindles) from our serial production are used for example in the actuator technology for medical engineering and for the furniture industry. The fabrication steps used for the serial stems (spindles) usually consist of thread rolling or whirling with a subsequent turning process.

We manufacture large stems (spindles) up to a length of 6.000 mm with matching threaded bushes and nuts. For example for valve construction as well as for power plant, waste water and stage technology.
