T h e m oto r e nsu re s no l os s of p re l oad o r rigidity when grinding tools, and ANCA's control algorithm eliminates reversal errors and maintains accuracy, the company says. This technology is said to enable grinding to an average sur face finish roughness as low as 164.7 Nm (0.16 Ra). ANCA Inc., call 248-926-4466 or visit anca.com. THREE WHEELS ENABLE GRINDING IN SINGLE CLAMPING Junker's Jumat 6S 18-20-18 grinder enables single-clamping grinding with short cycle times by simultaneously using three grinding wheels while still ensuring maximum quality. Wheelheads on all three grinding wheels feature separate X and Z axes, enabling simultaneous workpiece grinding. One grinding spindle ensures precise taper and plane surfaces (X1, Z1), another takes c a re of the shoulde r ( X 2, Z 2), w hile the last spindle grinds the internal diameter and shoulder (X3, Z3). The machine is said to of fer advantages in grinding gear wheels because of the workpiece support design, which consists of a hydrostatic bearing and precision power chuck. The center clamp enables the workpiece to be ground simul- taneously on both sides.
