Luren Precision offers its LUG-3040 CNC universal grinding machine, which uses the topography grinding method rather than generating grinding. The machine accommodates workpieces ranging from 20 to 250 mm (0.8" to 9.8") in outer diameter and as long as 300 mm (11.8"). The workpiece spindle is driven by a direct-drive motor, while the 20.50-kW (33.3-Nm) grinding spindle is driven by a built-in motor and turns at speeds ranging to 10,000 rpm. The grinding wheel diameter ranges from 100 to 230 mm (3.9" to 9.1") with a width of 30 mm (1.2"). Maximum grinding depth or spur is 35 mm (1.4").
The grinding machine is equipped with a FANUC control, and software functions include hob sharpening for spur and helical hobs; shaper cutter sharpening for helical shaper cutters; standard gear profile grinding for spur and helical gears; and shaving cutter sharpening for traditional and plunge-type shaving cutters.
