April 22, 2006—Accura Technics’ newest product is designed for precision grinding applicable to aerospace, automotive, bearing and optics manufacturing. In capability tests, Accura’s Model 1210GCNC grinder produced .000010" roundness in ball bearing outer races and .000006" (0.15 micron) roundness in inner races.

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 company’s 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.
