External cylindrical grinding with Quickpoint of Junker, brand marketed by Machinery Eurotec, involves a grinding external at high speed with only a sliding contact puntiforme. This technology of machining is very versatile and compared to conventional machining, provides a higher yield up to 600%, especially in the machining of hard metals. The typical parts of production to this range of equipment are engine valves, trees of cam, driveshafts, driving axles, shafts of pumps, etc.

Machining with Quickpoint is a high speed external cylindrical machining and contact between grinding wheel and in the area of the finished piece is about the size of a point. QUICKPOINT used a grinding wheel of CBN or diamond of extremely low wear and a few millimeters wide. The inclination of the axis of the grinding wheel on the horizontal axis of the piece creates an angle free, thus reducing the contact line to a point.

Complete machining in one single set-up of the piece

External cylindrical grinding machines can be extended to the machining of complete, integrated modules of Junker grinding modified with several teeth. This allows for example grinding plongée threads, forms and cylindrical not a single subject of the piece.

As main economic advantages of this system, include large savings of investment thanks to the rational production, now that virtually all the contours can machine with a single tooth and a single subject of the piece. The outline of the piece you enter directly through the software. It also highlights the high level of achievement, of the order of 88-95%, with 3-8% higher than in conventional processes. Involves also increased productivity due to machining complete with a single subject and simplification of the simplified logistics, since there is no need for a change of subject or use several machines. Also costs in equipment also reduces, to be his longest life and offers greater production security and versatility of using a single machine and not a whole production line.

With this system is already achieved significant savings for investment that practically all the contours can be machined with a single tooth and a single subject of the piece

The typical parts of production to Quickpoint are engine valves, trees of cam, driveshafts, driving axles, shafts of pumps, etc.Junker booth in the last edition of AMB.

Also, the Junker system offers technical benefits as the highly versatile: for flat walls, cones, chamfers, plongée, carved, thread, surfaces and multiple edges. Also the high speeds of machining thanks to implement the coolant at the point of grinding from all angles, and a higher quality thanks to the complete machining in one single set-up of the piece. This complete machining is even of both ends of the piece (as arrastrador is not used), with a high quality of the surfaces.

With its three types and five combinations of spindle portamuela head, the Quickpoint series offers solutions for external cylindrical grinding for all uses: from the compact 1000 Quickpoint for small parts and a wide range of parts to the 5000 Quickpoint for mass production. QUICKPOINT allows machining virtually all materials and their combinations: steel, aluminum, hard metal, industrial ceramics, sinter material, plastics, glass. In combination with other Junker technologies, machines of this series can also machined surfaces, edges multiple, carved, and threads of torque.
