Accura Technics New Grinder Works on Multiple Surfaces
The 1210G is equipped with a hydrostatic bearing workhead and two wheelheads: an air bearing ID/OD spindle, and a ball bearing rotary surface spindle. The two wheelheads are mounted on independent CNC axes. These axes are driven by ball screws and servomotors while the X-axis is driven by a linear motor. The three slides are mounted on a thermally stable, natural granite base.
The 1210G has a 12" (300 mm) swing and 10" (250 mm) workpiece height capacity. Standard X-axis travel is 14" (350 mm). Standard Z-axis travel is 12" (300 mm). The machine can be fully automated with robot loader, conveyors and gaging. Optional features include C-axis for non-round grinding and acoustic emission monitoring system.
According to the companys press release, Accura is also developing a larger vertical grinder with 30" (750 mm) diameter capacity for applications in the aerospace, bearing and heavy equipment industries.
