Wave springs developed to order: We work closely with you in the development of our wave springs for the intended application. Where necessary, we are pleased to assist you with processes ranging from dimensioning to verification to production. With the help of our specialist expertise, we will find the right solution for you together. We produce both single-turn and multi-turn designs with wavy and straight surfaces.

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.

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.

Advantages - Very short refacing time - Easy to use - Modular add-on components - 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.

The AC potentiometers in a rugged Ø20 mm housing are ideal for applications where a precise and economical multiturn potentiometer is required. The precision potentiometers of the AC series have an additional sintered bearing in the back cover and provide the shaft with improved stability. The completely encapsulated housing increases the robustness in addition. The potentiometer is available in 5 or 10 turn version. Seamless moulded housing with 2 x sleeve bearings provides additional stability Robust and accurate multi-turn sensor Inch-dimension shaft and bushing Centering collar for precise centre alignment Optional IP65 protection by sealing ring On request with limit switch and slipping clutch

CBN (cubic boron nitride) is the next hardest material after diamonds. When properly used, tools made from CBN exhibit considerably less wear than other materials. Cutting inserts or even VHM tools can be equipped with CBN. Technical application: Hardened tool steels with hardnesses greater than 55 HRC or high speed steels (HSS) can be machined without problems using CBN. Case hardened steels and chilled cast iron can also be machined with CBN. Non-ferrous metals are totally unsuitable for CBN; diamond tools are needed for these.

Thread turning is a special turning process.In thread turning a distinction is made between three different forms of presentation; the use of these depends on the thread pitch, the machine tool, the work-piece material and the cutting edge geometry. In the case of large threads, the tool must traverse the same track several times, penetrating deeper each time. The full depth of cut is therefore divided into several smaller cuts, thus preventing an overload on the sensitive tip of the thread profile of the cutting edge. In order to ensure profile accuracy, the helix angle of the thread must coincide as far as possible with the angle of inclination of the threaded plate. Thread turning method

Complex machining processes can now be completed with fewer tools as a result of the use of profile turning tools (also called turning-milling tools). The use of profile turning tools enables the number of tool positions in the tool changer to be reduced.

In face turning the tool moves vertically to the axis of the work-piece. When rough machining, a tool movement from the outside of the work-piece to the inside is preferred; in finish machining, the preferred movement is from the inside to the outside. The largest possible corner radius should be chosen in order to ensure optimal tool stability and cost-effectiveness.

When turning outside diameters, it is necessary to consider which clamping system should be used and which components will be made most often. This is because if larger components are to be turned (and therefore with correspondingly greater depths of cut) a different system must be used than when turning smaller components with a finishing pass. Determining the cutting direction and tool holder A turning tool which works from right to left is called a right-hand turning tool because it machines the right-hand side of the work-piece (when looking at the tool point, the main cutting edge of the turning tool is on the right).

ZINNER PKD or highly positively polished cutting inserts are used for machining aluminium and copper. Glass-fibre reinforced materials are machined with PKD or coated PKD tools. Diamond tools are ideally suited for the high gloss turning of non-ferrous metals.
