Six-axis tool grinder offers modular solution

The new 6-axis Ewamatic Line can grind complex forms in carbide, PCD and super-hard PCBN tooling and inserts to an accuracy of 0.002 mm via its innovative star-shaped grinding spindle holder (up to two wheels per spindle end).

In addition, an erosion unit is offered for the combined erosion and grinding of PCD materials in a single set-up.

It is based on a modular design enabling specific tooling/production demands to be met.

With automatic wheel dressing, linear handling, 4-axis robot loading and workpiece stacker all contributing to the benefits of unmanned multi-shift operation, the machine’s Ewag Pro Grind software also helps generate streamlined production routines.

With X, Y and Z-axis movements of 360 mm by 240 mm by 240 mm, and resolutions in these axes of 0.0001 mm (and similar resolutions in the B, A and C axes), the Ewamatic Line offers +/- 135° in the B (swivel) axis and – 15° to + 25° in the A (grinding head) axis. The machine’s C axis is the workhead with side clamping.

The 7.5 kW spindle provides 200 to 6,000 rpm (optionally, 1,000 to 12,000).
