Overview

The Kellenberger K100 is a universal cylindrical grinder sold as a set of sizes, not as one machine: centre distances of 600 / 1,000 / 1,700 mm, centre heights of 200 / 250 mm (7.9 / 9.8 in) and workpiece weight ratings of 100 / 150 / 200 kg (220 / 331 / 441 lb). The grinding spindle is 11.5 kW and the control is FANUC 31i-B.

Choosing the size is the first decision. The centre height sets the swing, under 400 mm (15.7 in) or under 500 mm (19.7 in), and the footprint is listed as 2.7 m × 2.2 m or 3.4 m × 2.2 m. The table does not pair each weight rating with a centre distance or height, so confirm which rating belongs to the version being quoted, especially for the 1,700 mm machine, where a long steel shaft reaches 200 kg quickly.

On the wheel side the K100 has more to work with than the Kellenberger K10, whose table lists 7.5 kW of spindle power. Here the external wheel is Ø 400 x 63 mm or Ø 500 x 100 mm, peripheral speed is 50 / 63 m/s, and the internal spindle is listed at 15 kW and 90,000 rpm. A 100 mm wide wheel with 11.5 kW behind it suits plunge grinding of long bearing seats.

The wheelhead swivels through 280° on a B axis with a resolution of 0.00001 degrees, so angles are set by the control instead of by hand and more than one wheel can be brought to the part. Linear axis resolution is 0.00001 mm, roundness is listed as 0.4 / 0.2 μm and X travel is 370 mm (14.6 in). The workhead runs at 1 - 1,000 rpm on an MT5 taper, and the MT4 tailstock has 49 mm (1.93 in) of stroke.

Frequently Asked Questions

01 What sizes does the Kellenberger K100 come in?

Centre distance is 600, 1,000 or 1,700 mm and centre height is 200 or 250 mm (7.9 / 9.8 in), giving a maximum workpiece diameter of under 400 mm (15.7 in) or under 500 mm (19.7 in). Footprint is 2.7 m × 2.2 m or 3.4 m × 2.2 m. Maximum workpiece weight is listed as 100 / 150 / 200 kg (220 / 331 / 441 lb).

02 What spindles does the K100 have?

The external grinding spindle is 11.5 kW and takes a Ø 400 x 63 mm or Ø 500 x 100 mm wheel at a peripheral speed of 50 or 63 m/s. The internal grinding spindle is listed at 15 kW and 90,000 rpm. Both sit on a wheelhead that swivels through 280° on the B axis.

03 How is the K100 different from the Kellenberger K10?

The Kellenberger K10 is listed with a single 1,000 mm length, 365 mm (14.4 in) of X travel, 7.5 kW of spindle power and a FANUC 0i-TF Plus control. The K100 adds a choice of three centre distances up to 1,700 mm, an 11.5 kW grinding spindle, a 15 kW internal spindle and the FANUC 31i-B control, with 370 mm (14.6 in) of X travel.

04 How accurate is the K100?

Linear axis resolution is 0.00001 mm and B-axis resolution is 0.00001 degrees. Roundness is listed as 0.4 / 0.2 μm; the table does not state the condition attached to each value, so ask which one the quoted configuration is accepted to.

05 What are the workhead and tailstock specifications of the K100?

The workhead runs at 1 - 1,000 rpm with an MT5 taper. The tailstock has an MT4 taper and 49 mm (1.93 in) of stroke. The electrical supply is 400 / 460 V. Machine weight is not in the table, so request it with the foundation plan.
