Overview
The Klingelnberg C 50 Bevel Gear Cutting Machine is an Oerlikon bevel gear cutting machine with 6-axis CNC, built for dry cutting of workpieces up to Ø 500 mm. Its normal module range depends on the method: 1.5 – 9 mm in continuous indexing and 1.5 – 11 mm in single indexing, with a maximum tooth width of 90 mm.
Dry cutting shapes the rest of the specification. With no cutting oil to carry chips and heat away, that job falls to extraction and filtration, and Klingelnberg states the 50 kVA total connected load without the filter system. Budget electrical supply and floor space for that unit as well as for the machine. The same goes for loading: the outside dimensions of 4,860 x 3,300 x 3,350 mm are given without integrated workpiece loading.
Both spindles top out at 450 rpm. That is low next to the 1,500 rpm of the C 30, and it fits the tooling. The cutter head row gives 88 – 181 mm, with 6 to 16 in sizes shown in brackets, and the continuous indexing heads carry 5 – 19 blade groups. Large heads reach their cutting speed at modest rpm; what they ask of the machine is torque and stiffness, and the net weight of 33,500 kg (approx.) is the figure that speaks to stiffness here.
Gear geometry runs from a spiral angle of 0° to 60°, from 6 to 180 teeth and from a 1:1 to a 1:10 ratio. The cutter head seat is a Gleason outer cone No. 14 (1:24, Ø 58.227 mm). On the work side the spindle takes an Oerlikon inner cone No. 80 (1:16, Ø 203.218 mm) and has a Ø 190 mm opening, which leaves room for long pinion shanks and draw rods.

Strengths & Limitations
Strengths
- Dry cutting on a 6-axis CNC machine, as stated in the machine type row
- Single indexing extends the normal module range to 11 mm; continuous indexing covers 1.5 – 9 mm
- Workpiece spindle opening of Ø 190 mm behind an Oerlikon inner cone No. 80 seat
- Net weight of 33,500 kg (approx.) behind a Ø 500 mm workpiece capacity and a 90 mm tooth width
- 5 – 19 blade groups in continuous indexing with cutter heads of 88 – 181 mm
Limitations
- Both spindles are limited to 450 rpm, so small cutter heads cannot reach the 1,500 rpm available on the C 30
- The 50 kVA connected load excludes the filter system that dry cutting depends on
- Listed dimensions of 4,860 x 3,300 x 3,350 mm exclude integrated workpiece loading, so an automated cell needs more floor
- Continuous indexing stops at 9 mm normal module; anything coarser up to 11 mm has to be cut by single indexing

Frequently Asked Questions
01
Klingelnberg's machine type row describes the C 50 as an Oerlikon bevel gear cutting machine with 6-axis CNC for dry cutting. The 50 kVA connected load is stated without the filter system, so that unit has to be planned for separately.
02
It depends on the method. In continuous indexing the normal module range is 1.5 – 9 mm. In single indexing it is 1.5 – 11 mm. In both cases the maximum workpiece diameter is Ø 500 mm and the maximum tooth width is 90 mm.
03
The cutter head spindle and the workpiece spindle are each listed at a maximum of 450 rpm. The C 30 runs both of its spindles to 1,500 rpm, so the smaller machine is the one for small, fast cutter heads.
04
The machine measures 4,860 x 3,300 x 3,350 mm (L x W x H, approx.) without integrated workpiece loading and has a net weight of 33,500 kg (approx.). Total connected load is 50 kVA without the filter system. Both exclusions add to the real footprint and supply.
05
The workpiece spindle seat is an Oerlikon inner cone No. 80 with a 1:16 taper and a diameter of Ø 203.218 mm. The spindle opening is Ø 190 mm. On the tool side the cutter head spindle seat is a Gleason outer cone No. 14, 1:24, Ø 58.227 mm.
