Overview

The Klingelnberg G 60 is an Oerlikon bevel gear grinding machine — a hard-finishing machine, not a gear cutter. It grinds hardened bevel gears up to 600 mm workpiece diameter, at normal modules from 2 to 12 mm, with a maximum facewidth of 110 mm and tooth counts to 360. The basic angle setting range of ±90° gives it the geometric reach to cover a wide spread of bevel gear designs on one setup family.

Grinding is driven by a 22 kW nominal grinding wheel drive with a grinding spindle running to 4,500 rpm. Wheels from 102 to 406 mm (4–16 in) diameter mount on an HSK-E63 E tool spindle seat to DIN 69893-5, with a maximum wheel height of 135 mm including the base plate. The eccentric axis runs to 3,800 rpm, and the dresser to 6,000 rpm — form dressing is integrated into the machine, so wheel geometry is restored in place rather than by swapping to a pre-formed wheel.

The workpiece side is built around a spindle with a 203.218 mm (8 in) inner cone seating diameter, a 150 mm bore, and 740 mm of work spindle depth, turning at up to 40 rpm. That depth and bore combination is what lets shaft-type pinions pass into the spindle rather than being held on an overhung fixture, which matters for the pinion half of a bevel gear set as much as the ring gear half.

Site requirements are substantial. The machine weighs approximately 22,900 kg net without the filter system, and the published envelope of roughly 5,620 x 4,500 x 3,190 mm includes the filter system. Total connected load is 57 kVA, quoted without the filter system — grinding coolant filtration is an addition to that figure.

The G 60 occupies the hard-finishing station in a bevel gear line. The tooth form is generated upstream by a cutting machine on a soft blank; the blank is then carburized or case hardened, which distorts it; and the G 60 grinds the hardened flanks back to final geometry and surface finish. It removes heat treatment distortion, which is work that no amount of cutting accuracy upstream can substitute for.

Strengths & Limitations

Strengths

600 mm grinding capacity with modules from 2 to 12 mm, facewidth to 110 mm, and tooth counts to 360
22 kW nominal grinding wheel drive with a grinding spindle to 4,500 rpm
Accepts a wide wheel range — 102 to 406 mm (4–16 in) diameter, up to 135 mm height including base plate — on an HSK-E63 E tool spindle seat to DIN 69893-5
Integrated dressing with dresser speeds to 6,000 rpm restores wheel form in place, without swapping to pre-formed wheels
150 mm work spindle bore with 740 mm of spindle depth accommodates shaft-type pinions rather than only disc-type ring gears
Plus/minus 90 degrees basic angle setting range covers a broad bevel gear geometry envelope

Limitations

Approximately 22,900 kg net and an envelope of roughly 5,620 x 4,500 x 3,190 mm require dedicated, reinforced floor space with crane access
The 57 kVA total connected load is quoted without the filter system, so grinding coolant filtration adds to the electrical and space budget
600 mm workpiece diameter and 110 mm facewidth cap the size of gear set it can finish
As a hard-finishing station it depends on upstream soft cutting and heat treatment — it is one machine in a chain, not a standalone route from blank to finished gear

Best For

Hard finishing of carburized bevel gear sets up to 600 mm diameter and 110 mm facewidth Truck axle, construction equipment, marine, and industrial gearbox producers grinding large ring gears and pinions Shops needing wheel diameters across the 102–406 mm range with integrated dressing to handle varied gear geometries Pinion grinding where the 150 mm bore and 740 mm work spindle depth are needed to hold shaft-type parts

Frequently Asked Questions

01 Does the Klingelnberg G 60 cut bevel gears or grind them?

It grinds. The G 60 is an Oerlikon bevel gear grinding machine, specified with a 22 kW nominal grinding wheel drive, a grinding spindle to 4,500 rpm, wheels from 102 to 406 mm diameter, and an integrated dresser running to 6,000 rpm. The tooth form is produced upstream by a cutting machine; the G 60 finishes it after heat treatment.

02 What size bevel gears can the G 60 grind?

Up to 600 mm workpiece diameter, with normal modules from 2 to 12 mm, a maximum facewidth of 110 mm, and up to 360 teeth. The basic angle setting range is ±90°.

03 What grinding wheels and dressing does the G 60 use?

Wheels from 102 to 406 mm (4–16 in) diameter, up to 135 mm high including the base plate, mounted on an HSK-E63 E tool spindle seat to DIN 69893-5. Maximum grinding spindle speed is 4,500 rpm, the eccentric runs to 3,800 rpm, and the integrated dresser to 6,000 rpm.

04 Can the G 60 hold shaft-type pinions as well as ring gears?

The workpiece spindle has a 203.218 mm (8 in) inner cone seating diameter, a 150 mm bore, and 740 mm of spindle depth, running to a maximum of 40 rpm. That bore and depth allow shaft-type pinions to be taken into the spindle rather than held entirely overhung.

05 What are the G 60's installation requirements?

Approximately 22,900 kg net without the filter system, in an envelope of roughly 5,620 x 4,500 x 3,190 mm including the filter system. Total connected load is 57 kVA without the filter system, so grinding coolant filtration must be budgeted on top of that.
