Hardinge Kellenberger T1000

The Kellenberger T1000 is a short-bed cylindrical grinder with a lot of wheel for its length: 400 mm (15.7 in) between centres, a grinding spindle of 10 / 20 kW and wheels up to Ø 600 x 120 mm. It runs on a Siemens SINUMERIK ONE control and stands on a 2.4 m × 2.9 m footprint.

The proportions point to production work on short parts. With only 400 mm between centres but a 120 mm wide wheel available, a large share of a part's length can be ground in a single plunge, and the 20 kW option is there to drive that width. Wheel choices are Ø 400 x 80 mm, Ø 500 x 120 mm and Ø 600 x 120 mm, with peripheral speeds of 45 / 60 m/s. The table does not tie each wheel to a power or speed rating, so the quotation should spell out the combination.

Two centre heights are offered, 125 / 175 mm (4.9 / 6.9 in), for workpiece diameters under 250 / 350 mm (9.8 / 13.8 in). Workpiece weight is 150 kg (331 lb), a high figure against the 400 mm length, so heavy short parts such as gear blanks, hubs and flanged shafts fit. The workhead taper is MT5 / MT6 and the tailstock is MT3 with an 80 mm (3.15 in) stroke.

Axis travel is 600 mm (23.6 in) in Z and 350 mm (13.8 in) in X, with rapid traverse listed as 15 000 mm/min in X and 30 000 mm/min in Z, so loading and dressing moves take little of the cycle. Scale resolution is 0.01 µm and roundness is listed as 0.4 / 0.2 μm. A spindle speed row reads 1 - 1 500 / 3 000 min-1 without stating which option each range belongs to. Electrical supply is 400 V / 460 V at 35 A - 80 A.
