Overview

The Kellenberger TM300 is a 5-axis turn-mill centre for parts up to Ø 700 mm (27.6 in) and 1,500 mm (59.1 in) long. A 3,500 rpm main spindle with 600 Nm (442 ft-lb) of torque and an A2-8 nose does the turning, and an HSK T63 milling spindle with 12,000 rpm and 100 Nm does the rest.

The milling spindle sits on a B axis that swivels through 240 degrees, with 300 mm of Y travel, and the axes are listed as 5-axis simultaneous. In practice that means angled holes, pockets off the centre line and contoured surfaces can be machined on a turned part without moving it to a machining centre. The magazine holds 40 tools, which has to cover both the turning tools and the milling cutters, so a long programme with many special tools needs the magazine planned.

The second end of the part is handled according to the variant. The TM300S and TM300ST carry a sub-spindle, listed at 477 Nm / 433 Nm respectively, and the TM300ST also has a servo tailstock with an MT5 taper. A sub-spindle allows the back of the part to be finished after transfer; a tailstock supports a long shaft during heavy turning. With 1,500 mm of turning length available, the choice depends on whether the work is shafts or shorter chucked parts.

This is a large machine: 15,000 kg (33,069 lb) on a footprint of 6,000 × 2,452 × 2,700 mm. The control is Siemens SINUMERIK ONE with a 22-inch touchscreen. The table gives torque for each spindle but no power figure, and no X or Z travel or rapid rate, so those belong on the list of questions for the supplier.

Strengths & Limitations

Strengths

Turning capacity of Ø 700 mm (27.6 in) by 1,500 mm (59.1 in)
Main spindle with 600 Nm (442 ft-lb) of torque, 3,500 rpm and an A2-8 nose
HSK T63 milling spindle with 12,000 rpm and 100 Nm on a B axis with 240 degrees of swivel
5-axis simultaneous machining with 300 mm of Y travel
Tool capacity of 40 tools shared between turning and milling
Sub-spindle on the TM300S and TM300ST (477 Nm / 433 Nm), and a servo tailstock with MT5 taper on the TM300ST

Limitations

The sub-spindle and the servo tailstock belong to the TM300S and TM300ST variants, not to every version
Milling spindle torque is 100 Nm, which limits heavy milling in steel next to the 600 Nm available for turning
No spindle power, X or Z travel or rapid traverse figures are listed
Weighs 15,000 kg (33,069 lb) and needs a 6,000 × 2,452 × 2,700 mm space

Best For

Complete machining of shafts up to 1,500 mm (59.1 in) long Large chucked parts up to Ø 700 mm (27.6 in) Turned parts with angled holes and milled features, using the 240 degrees B axis Two-sided machining on the sub-spindle variants TM300S and TM300ST

Frequently Asked Questions

01 What size of part can the Kellenberger TM300 machine?

Maximum turning diameter is Ø 700 mm (27.6 in) and maximum turning length is 1,500 mm (59.1 in). Y travel is 300 mm. The table does not give X or Z travel separately, or a maximum part weight, so check those against the heaviest job planned.

02 What is the difference between the TM300, TM300S and TM300ST?

The table distinguishes them by what faces the main spindle. The TM300S and TM300ST have a sub-spindle, with torque listed as 477 Nm / 433 Nm respectively. The TM300ST additionally has a servo tailstock with an MT5 taper. No sub-spindle or tailstock figure is given for the base TM300.

03 What spindles does the TM300 have?

The main turning spindle has an A2-8 nose, a maximum speed of 3,500 rpm and 600 Nm (442 ft-lb) of torque. The milling spindle takes HSK T63 tooling and is listed at 12,000 rpm and 100 Nm. Spindle power is not published for either.

04 Is the TM300 a full 5-axis machine?

The axes are listed as 5-axis simultaneous. The milling spindle swivels on a B axis through 240 degrees and there is 300 mm of Y travel, so contoured surfaces and compound-angle features can be cut in one clamping. The control is Siemens SINUMERIK ONE with a 22-inch touchscreen.

05 How many tools does the TM300 hold, and how big is the machine?

Tool capacity is 40 tools. The machine weighs 15,000 kg (33,069 lb) and its footprint is listed as 6,000 × 2,452 × 2,700 mm, so floor loading, crane access and door height all need checking before the machine arrives.
