Mitsui Seiki Jig Grinders

Jig Grinders:

• V-F sliding surfaces of X- and Y-axes, spindle head, top and bottom sides of horizontal bridges are scraped for extremely high geometric precision (all models).

• Z-axis is NC-controlled and two types of control (Z-axis as cutting feed and Z-axis as chopping cycle) are available.

• As for Z-axis chipping cycle, the ball screw drive has realized the high speed of 200 cycles/min (at 25 mm stroke). Even at this speed, the bottom dead center precision is 2µm (300G, 4GDN, 6GCN).

• In 3GEN, the linear motor is adopted to the Z-axis (first practical application for machine tools). Z-axis chopping cycle of 400 cycles/min (at 25 mm stroke), which was impossible for traditional models, has been realized to drastically reduce the process time of contouring cutting.

• Low thermal expansion casting is adopted for the head material. Error due to heat displacement is extremely small (all models).

• Ultra-precision accuracy operations provides efficiency grinding of exotic materials, fine ceramics, carbide and conventional materials that demand jig grinding tolerances.

• Integrated circuit logic, closed loop, complete electrical equipment for operation on 3-phases 50/60Hz 200/220 Volts AC

• CNC Control Fanuc 15iMA (300G, 3GDN, 3GEN)

• CNC Control Fanuc 15iMB (4GDN)

• CNC Control Fanuc 30i (6GCN, 7GAN)
