Our best estimate for a cnc gear cutting machine in this class — not a quote from Klingelnberg. Configuration moves it a long way.
Overview
The Klingelnberg C 30 is a bevel gear cutting machine for workpieces up to Ø 280 mm, with a normal module range of 1.5 – 6.5 mm and a maximum tooth width of 58 mm. One table covers both cutting methods: continuous indexing with cutter heads of 39 – 105 mm and 5 – 19 blade groups, and single indexing with cutter heads of 3.25" – 7.5".
Spindle speed is what separates it from its larger relative. The cutter head spindle and the workpiece spindle each run to 1,500 rpm, against 450 rpm on both spindles of the C 50. Small cutter heads need high rotational speed to reach a workable cutting speed, and a 39 mm head is small, so the fast spindles and the small-module range belong together. Geometry limits are wide for the size: spiral angles from 0° to 60°, 6 to 180 teeth and gear ratios from 1:1 to 1:10, which puts zero-spiral-angle designs and high-ratio sets inside the stated range.
Check the tooling interfaces before ordering arbors or moving work from another machine. The cutter head spindle has a Ø 58.227 mm seat, a Gleason outer cone No. 14 with a 1:24 taper. The workpiece spindle offers an Oerlikon outer cone of Ø 140.11 mm (1:4) and an Oerlikon inner cone No. 39 of Ø 99.258 mm, and its Ø 93 mm opening caps the shank diameter that can pass through.
For installation, Klingelnberg lists a total connected load of 40 kVA without the filter system, a weight of approx. 20,000 kg and outside dimensions of approx. 4,500 x 3,410 x 2,900 mm. The filter system adds to the electrical load and needs its own place in the layout.

Strengths & Limitations
Strengths
- Cutter head spindle and workpiece spindle both run to 1,500 rpm, against 450 rpm on the C 50
- Covers continuous indexing (cutter heads 39 – 105 mm, 5 – 19 blade groups) and single indexing (cutter heads 3.25" – 7.5")
- Spiral angles from 0° to 60°, 6 to 180 teeth and gear ratios from 1:1 to 1:10
- Workpiece spindle has both an Oerlikon outer cone (Ø 140.11 mm) and an Oerlikon inner cone No. 39 (Ø 99.258 mm)
- At approx. 20,000 kg it is a much lighter installation than the C 50 at approx. 33,500 kg
Limitations
- Workpiece diameter stops at Ø 280 mm and normal module at 6.5 mm
- Maximum tooth width is 58 mm, which rules out wide-face gear sets
- The 40 kVA connected load is stated without the filter system, so the full electrical demand is higher than the table figure
- Workpiece spindle opening is Ø 93 mm, which limits the shank that can pass through the spindle

Frequently Asked Questions
01
Klingelnberg lists a maximum workpiece diameter of Ø 280 mm, a normal module range of 1.5 – 6.5 mm and a maximum tooth width of 58 mm. Tooth counts run from 6 to 180 and gear ratios from 1:1 to 1:10, with spiral angles from 0° to 60°.
02
For continuous indexing the cutter head diameter is 39 – 105 mm with 5 – 19 blade groups. For single indexing the cutter heads are 3.25" – 7.5". The cutter head spindle seat is Ø 58.227 mm, a Gleason outer cone No. 14 with a 1:24 taper, and the spindle runs to 1,500 rpm.
03
The C 30 is the smaller and faster machine. It takes workpieces to Ø 280 mm and runs both spindles to 1,500 rpm, while the C 50 takes Ø 500 mm at 450 rpm. The C 30 weighs approx. 20,000 kg against approx. 33,500 kg for the C 50.
04
The total connected load is 40 kVA, stated without the filter system. The machine weighs approx. 20,000 kg and measures approx. 4,500 x 3,410 x 2,900 mm (L x W x H). Allow extra power for the filter system and ask whether the dimensions include it, since the table does not say.
05
Two seats are listed: an Oerlikon outer cone of Ø 140.11 mm with a 1:4 taper, and an Oerlikon inner cone No. 39 of Ø 99.258 mm. The spindle opening is Ø 93 mm and the workpiece spindle runs to 1,500 rpm.
