Thread grinder offers superior accuracy
Seven Axis CNC universal thread grinding machine combines superior accuracy and surface finish with versatility and rapid setup.
The PS52 is a parallel operation machine, i e, it unloads/loads, point grinds, and split point grinds simultaneously, to provide maximum throughput.
The PS52 consists of an automatic unloading, loading and cutting edge location assembly; a point grinding wheelhead assembly with CNC wheel dressing for grinding a wide variety of drill point geometries including standard radially relieved drill points, helical points, and multi-facet points; and a split point grinding wheelhead assembly with a diamond roll dresser capable of grinding NAS907 and DIN1412 Form A, B and C split points.
Drills are loaded with the cutting edge located into collet spindles.
The drills are then transferred between loading and grinding operations locked in the collet spindles to ensure accuracy of the point relief orientations relative to the flute cutting edge.
A complete size changover can be accomplished within 30 minutes or less, and average cycle time less than 20 seconds per piece, floor to floor.
