This machine can be supplied with either 230mm or 300mm of carriage travel to suit the different sizes of cutter block length. The machine can also be supplied with either a pivot carriage or a multidirectional linear carriage. A rapid and precise machine for grinding cutters to shape, and at the correct main and side clearance angles, using a metal template profiled to the reverse of the pattern required. Cutters are normally ground in the block and are then precisely aligned radially and laterally to require neither setting nor balancing. The machine automatically develops out the true cutter profile needed using a template formed either to a drawing or shaped to fit square on a sample mould. The same template can be used to form any combination of circular, square, straight or shear cut heads, or router cutters, each to produce perfectly matching moulds. A built in diamond dresser dresses the grinding wheel at the point of grind to guarantee alignment of the stylus and wheel each time dressed. The same dresser forms the wheel to half round, square, single or double angle sections and will also side dress. The grinding wheel offsets automatically when tilted for side clearance and grinds the cutter only where needed - this avoids spoiling the edge where opposite side clearance is required.
MAIN FEATURES
- Suitable for HSS, Stellite or Tungsten carbide tipped cutters.
- Cutters ground in the head for absolute accuracy.
- Head can be secured in any position along the arbor.
- Automatic development of the correct cutter profile regardless of cutting or shear angle.
- Needs less operating skill, but produces superior results.
- Template simply produced from a drawing or sample.
- Self aligning styli.
- Accurately formed profiles - absolutely repeatable.
- Main clearance angle variable between 15 and 40 degrees.
- Side clearance angles 5 or 10 degrees (15 optional).
- Side clearance grinding precisely controlled and repeatable - no chance of spoilt edges - no compensatory adjustments needed.
- Diamond dresser forms and precisely positions the grinding wheel - guarantees absolute repeatability and constant radial height of cutters.
- Economic grinding wheel life by using full wheel profile.
- Re-circulating coolant for fast grinding without burning.
- Wide spacing of arbor supports allows fitting of most types of cutter heads, including self centering square heads.
- Suitable for profile grinding replacement tips on one piece profile heads, either straight or shear cut type.
