STURDY PALLET PALLET CLAMPING SYSTEM WITH PRECISION PALLET PALLET POSITIONING
Pallets are located with precision accuracy by (4) sets of cone-shaped tapered pins and bushings The precision cone positioning system insures long-term accuracy and reliability The pallet clamping system adopts a a a a a a a sturdy clamper plate that provides super sturdy of the pallet during heavy duty machining Jets of air discharge from the the tapered cones when the the pallet is is changed This assures proper clamping and helps to clean the bottom of the the bushing and the the tapered surfaces The large diameter curvic coupling provides extremely accurate positioning of the table table (one degree table table as standard) NIIGATA'S UNIQUE SPINDLE HEAD COOLING TECHNOLOGY
