At Grindtec (18-21 March 2020, Germany), Walter Ewag will be introducing two new machines. The full details are still a secret until the doors open, but the company has already hinted at certain features.
It has been announced that one of the new arrivals will be the twin-spindle option for the Helitronic Power 400 tool grinder and for the Helitronic Power Diamond 400 ‘two-in-one’ tool eroding and grinding machine. The twin-spindle option machines offer 24 kW and are able to accommodate tools up to 520 mm long and up to 380 mm diameter.
In addition to releasing a number of other tool production and measurement innovations as part of the United Grinding Group display (Booth 2055, Hall), Walter Ewag UK says Walter will also show the Helicheck Plus tool measuring machine with integrated robot laser marking (after cleaning), while Ewag will have the Laser Line Ultra, Compact Line and Profile Line insert production machines on show.
While the Ewag Laser Line Ultra represents ultra-short pulse laser machining of all cutting materials, and accommodates inserts up to 200 mm diameter and up to 250 mm long, the six-axis Compact Line is designed for grinding (including peripheral grinding) inserts of tungsten carbide, cermet, ceramic, PCBN and PCD, the company explains.
The machine’s traverses in the X, Y and Z axes are 450 mm, 180 mm and 150 mm, respectively, while axis resolution is 0.0001 mm. The 5.5 kW grinding spindle produces 7,000 revs/min. A ‘three-in-one’ dressing unit ensures grinding wheel concentricity and process reproducibility, plus it offers wheel dressing, regeneration and ‘crushing’ in a single package.
