Danobat CG-1800

Q: How much does the Danobat CG-1800 cost?

The price estimate for the Danobat CG-1800 is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/danobat-cg-1800#price; the request is passed to Danobat or an authorised dealer.

Uncertain

We do not have a price for the Danobat CG-1800 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.

Overview

The Danobat CG-1800 stretches the CG production grinder to 1,800 mm (70.9 in) between centers and is the only CG model that grinds up to 540 mm (21 in) in diameter. Weight between centers stays at 500 kg (1,100 lb), so it is a machine for long parts of moderate mass: rotor shafts, ball screws, long spindles.

Its closest relative is not another CG but the CGX. Both share the envelope of 1,800 mm, 540 mm and 500 kg. They differ at the wheel. The CG-1800 takes a wheel up to Ø610 x 160 mm (Ø24 x 6.29 in) and Danobat quotes up to 25 kW (33.5 hp) for the CG wheelhead; the CGX lists a Ø508 x 80 mm (Ø20 x 3.14 in) wheel on a 15 kW (20.1 hp) external spindle. Put simply, this is the higher-stock-removal machine of the two.

Long, slender parts bring their own problems, and several listed features answer them. Synchronous tailstocks drive the shaft from both ends. Taper adjustment corrects a part that grinds larger at one end. The MDM in- and post-process gauge is described as scanning slender parts and is quoted at ±1.5 μm accuracy and 1 μm repeatability. None of this is called standard; it sits under customisation.

Maximum wheel peripheral speed is 80 m/s (15,750 sfpm) with constant peripheral speed control. The bed is natural granite and the axes run on linear motors. Before ordering, check the 500 kg (1,100 lb) limit against the heaviest shaft plus its drivers: the limit does not rise with the bed length.

Strengths & Limitations

Strengths

1,800 mm (70.9 in) between centers, the longest of the CG models
Grinds up to 540 mm (21 in) in diameter, against 440 mm (17 in) on the CG-600 and CG-1000
Ø610 x 160 mm (Ø24 x 6.29 in) wheel with up to 25 kW (33.5 hp)
Synchronous tailstocks and taper adjustment are available for long shafts
MDM gauge quoted at ±1.5 μm accuracy and 1 μm repeatability

Limitations

500 kg (1,100 lb) between centers is low for a part 1,800 mm (70.9 in) long and 540 mm (21 in) across
Steady rests are not named in Danobat's CG option lists, which matters for slender shafts
Peripheral speed limit of 80 m/s (15,750 sfpm)
The published table omits machine weight, footprint and axis travels

Best For

Rotor and stub shafts, long ball screws and machine tool spindle shafts Long parts up to 500 kg (1,100 lb) that need a wide, large-diameter wheel Screw compressor and electric motor shafts in series production Shops comparing a production-oriented wheelhead with the three-wheel CGX

Frequently Asked Questions

01 What are the main capacities of the CG-1800?

1,800 mm (70.9 in) maximum distance between centers, 540 mm (21 in) maximum diameter to be ground and 500 kg (1,100 lb) maximum weight between centers. The largest wheel is Ø610 x 160 mm (Ø24 x 6.29 in) and the maximum wheel peripheral speed is 80 m/s (15,750 sfpm).

02 CG-1800 or CGX: which one fits my parts?

Both grind parts up to 1,800 mm long, 540 mm in diameter and 500 kg. The CG-1800 has the larger wheel at Ø610 x 160 mm (Ø24 x 6.29 in). The CGX has a Ø508 x 80 mm (Ø20 x 3.14 in) wheel, a 15 kW (20.1 hp) external grinding spindle and a three-wheel configuration with two OD wheels and one ID wheel, so it leans towards versatility.

03 Can the CG-1800 measure parts in the machine?

Yes, as an option. Danobat lists a touch probe, in-process, post-process and non-contact measuring and the MDM automatic in- and post-process gauge. The MDM produces metrological reports covering roundness, radial run-out, cylindricity and diameters, and is quoted at ±1.5 μm accuracy and 1 μm repeatability.

04 Which tailstock options exist for long shafts on the CG-1800?

Manual and hydraulic tailstocks, synchronous tailstocks and taper adjustment are listed. The tailstock quill ranges from 80 to 170 mm (3.1 to 6.7 in) and tailstock axes with strokes of up to 600 mm (23.6 in) are available, which helps when the same machine grinds shafts of several lengths.
