In addition to releasing a number of other tool production and measurement innovations as part of the United Grinding Group display (Stand 2055, Hall 2), 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.
The Ewag Laser Line Ultra represents ultra-short pulse laser machining of all cutting materials, and accommodates inserts up to 200 mm diameter and 250 mm long. Also on the stand will be the Profile Line, which is targeted at the production of complex insert geometries, including interchangeable cutting inserts and rotationally symmetrical drilling and milling inserts of HSS, carbide, cermet and ceramic.
Finally from Ewag, the 6-axis Compact Line is designed for grinding (including peripheral grinding) inserts of tungsten carbide, cermet, ceramic, PCBN and PCD. The machine’s traverses in the X, Y and Z axes are 450, 180 and 150 mm, respectively, while axis resolution is 0.0001 mm. The 5.5 kW grinding spindle produces 7,000 rpm.
A ‘three-in-one’ dressing unit ensures grinding wheel concentricity and high process reproducibility, plus it offers wheel dressing, regeneration and ‘crushing’ in a single package. Machine usability and effectiveness is also guaranteed by the integrated ProGrind software, while the Fanuc control system enables all grinding routines to be programmed quickly and easily via its touchscreen panel.
Applying protective chamfers on the main cutting edges of inserts is facilitated by the machine’s optimised kinematics, as well as by the newly developed C axis. Machine downtime is minimised via the machine’s short travel distances and by the integrated 6-axis Fanuc robot that offers agile handling and a high degree of flexibility for loading complex inserts.
