Technical information When machining bar material particular care should be taken that as little material as possible is removed as cutting forces should be minimised and costs reduced. Therefore the exchangeable disc should be selected as a function of the work-piece which is to be parted. Tool systems Das RC-System und S-System sollte als erste Wahl bei den Abstechbearbeitungen verwendet werden. Die Schneidplatten wurden so gestaltet, damit der Span schmäler als die abzustechende Nut ist und ein optimaler Spanablauf gewährleistet werden kann. Das Z-CUT-DUO System ist bedingt durch die Doppelschneidplatte auf eine bestimmte Stechtiefe begrenzt.

Technical information Axial grooving is among the most technically difficult machining process in the whole field of metal removal. In this process the chip, once removed, must overcome not just the shaping of the material but also the circular movement. It is particularly important that the machining should always commence at the outer diameter of the axial groove as tool stability is in direct proportion to the diameter. It is preferable for the tool to be used underneath the work-piece so that the chips can fall downwards without obstruction. Tool systems The S System is a modular tool system which offers innumerable possibilities to the user. The cutting tips for this system are ground to a sharp edge and produce an excellent surface quality. It goes without saying that the cutting tips can be supplied with all required corner radii. The RC System is screw clamped; the cutting tip is securely clamped into position so that it cannot fall out. When rough turning, grooving depths of up to 100 mm are standard. When turning larger diameters we are also able to achieve grooving depths of 150 mm.

Technical information By using our internal grooving system it is possible to machine grooves on hole diameters starting from 2 mm. Tool systems With the proven TURN-CUT 2 cutting system you can machine grooves and longitudinally turn hole diameters starting with hole diameters of 16.5mm. When using A Series tools, grooving and longitudinally turning is possible on hole diameters starting from 2 mm.

Customised cutting tips are usually necessary for profile cutting. We have already custom-manufactured several thousand shapes for customers – and with short delivery times.

The short cutting systems in our sales programme cover all cutting tasks in this area.

Machining non-ferrous metals is really only different from the normal machining of steel by the use of special cutting tips and coatings.

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).

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.

Contrary to external turning, tool selection and tool use are of greater significance in internal turning as these are limited by the length and hole diameter of the work-piece. During internal turning it is very important to select a boring bar which is optimal for the hole diameter in order to minimise vibrations. Zinner tools are available in steel, heavy metal or hard metal shanks.

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.
