3-axis profiling machine creates bores and contours
Mitsui Seiki has introduced the PJ812 Precision Profile Center, 3-axis CNC vertical jig mill engineered to perform high-precision contour machining and precise boring of components with critical tolerances. It is suitable for parts for the mould and die, optical, aerospace, and medical industries.
The machining centre provides positioning accuracy and repeatability of +/- 1 µm. A thermal compensation system employs sensors on the machine faceplate and inside the spindle to minimize the effects of temperature changes on part accuracy and cut temperature-generated displacement by 60 per cent. This system also reduces Z-axis thermal growth and deflection by 30 per cent, the company states.
Cooling systems for slide way lubrication and ball screw cores stabilize axis feed precision.
Spindle choices include a 10,000-RPM, 50-taper spindle with (40/20 HP) direct-drive motors, and up to 30,000-RPM (24/20 HP) with 40-taper.
Travels (X/Y/Z) are 48, 32, and 20 in., respectively.
The machine table can accommodate a maximum load of 3,300 lbs. on its 48- by 32-in. work surface. A 40-tool-capacity ATC is standard.
