EWAG Compact Line

The EWAG Compact Line is a grinding machine for indexable inserts, sized for inserts from a 3 mm inscribed circle to a 50 mm circumscribed circle. The grinding spindle runs at 0 – 7,000 rpm, peak power is 5.5 kW and the wheel can be up to 250 mm in diameter.

The working envelope is small because the parts are small: 450 mm of X, 180 mm of Y and 150 mm of Z. Rapid traverse is 15 m/min in X and 10 m/min in Y and Z. Strokes on insert work are short, so those rates count for less than the resolution of the axes, which is 0.0001 mm on the linear axes and 0.0001° on the rotary ones. Figures that fine are what allow edge geometry and clearance faces to be held from one insert to the next.

The A axis covers - 15 to + 25°. Any geometry that needs more tilt than that falls outside the machine, so check the steepest angle in your insert range against it. The table also gives a pin diameter of 1.6 mm/10 mm, minimum and maximum. If your inserts are located on a pin through the bore, check the bore sizes against that range.

EWAG quotes the weight, approx. 4,000 kg, including the robot cell, and a power consumption of approx. 12 kVA. The EWAG Laser Line Ultra handles the same insert sizes on similar travels of 440 mm, 140 mm and 170 mm, but removes material with a laser. The Compact Line is the choice where the insert is to be ground with a wheel.
