Cutting tool grinding machine DRILLMAT

workpieceCNChigh-precision

A sharp cutting edge, precise concentricity, a long service life - twist drills for professional use must be manufactured to an exemplary standard without neglecting the cost aspect. This is achieved by DRILLMAT, which grinds from blanks made of HSS in a single clamping set-up to produce a finished twist drill. The grinding wheel package ensures a perfect ground finish for twist drills with even the most complex cutting edge geometry. Integrated loading and unloading systems reduce downtimes. Highlights - Face grinding prior to back grinding - 11/20 kW grinding spindle - Rapid retooling - CNC dressing unit Grinding process descriptions The DRILLMAT grinds flutes, the face geometry and the back in a single clamping set-up. Stable bushing support ensures the necessary rigidity during grinding operations, thus enabling maximum precision. Up to four corundum grinding wheels are mounted on the grinding spindle. With the DRILLMAT S, dressing is possible simultaneously with the grinding and loading sequence. The cooling nozzle system can be individually controlled with 4 channels for each grinding process. HSS twist drill: dia. 5 mm, total length 86 mm, flute length 52 mm, two flutes, Runout< 0.002 mm Cycle time: < 49 s Grinding task: Complete grinding MACHINE BED The machine bed made of mineral cast provides impressive damping behavior and torsional rigidity. The temperature stability allows fluctuations in the ambient temperature to be compensated with a minimum of effort, ensuring a high level of dimensional stability throughout the whole day.
