How much does the Supertec G25A-35CNC cost?
Price estimate
We do not have a price for the Supertec G25A-35CNC 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 Supertec G25A-35CNC is an angular-type CNC cylindrical grinder for parts up to Ø250 mm (Ø10 in) in diameter and 350 mm (14 in) between centers. Its Ø455 × 50 × Ø127 mm (Ø18 × 2 × Ø5 in) wheel is large for a machine of this length and runs at 1,650 rpm.
Why pick it over the plunge machine of the same swing? The G25P-50CNC offers 500 mm (20 in) between centers; this model gives up some of that length. In exchange it belongs to the angular family, the configuration normally chosen when a shoulder has to be ground square to a journal in the same cycle. If the parts are plain diameters, the plunge machine is the more flexible buy.
Behind the wheel is a 5 kW (6.7 hp) motor. Supertec's text for this page describes hydrostatic and hydrodynamic spindle bearings carried on a high pressure oil film, with an interlock that stops the spindle if oil pressure fails. The specification table itself records the spindle simply as bearing type, so confirm which construction is supplied.
Net weight is 3,100 kg (6,820 lb) and gross 3,500 kg (7,716 lb), in a crate of 2,970 × 2,250 × 2,250 mm (117 × 89 × 89 in). The table swivels 10°, the tailstock center is MT 3, and 80 kg (176 lb) is the most the centers will carry.

Strengths & Limitations
Strengths
- Ø455 × 50 × Ø127 mm (Ø18 × 2 × Ø5 in) wheel on a compact 350 mm (14 in) machine
- Maximum grinding diameter equals the swing at Ø250 mm (Ø10 in)
- 5 kW (6.7 hp) wheel spindle motor with 160 mm (6.3 in) of infeed travel
- Oil-pressure interlock on the wheel spindle, as Supertec describes it
- Crate size of 2,970 × 2,250 × 2,250 mm (117 × 89 × 89 in) at 3,500 kg (7,716 lb) gross
Limitations
- 350 mm (14 in) between centers, shorter than the 500 mm (20 in) of the G25P-50CNC
- Only 80 kg (176 lb) between centers
- The page's text and its table describe the wheel spindle bearings differently
- Automatic sizing, gap control, crash control and touch probe are optional equipment

Frequently Asked Questions
01
Up to Ø250 mm (Ø10 in) in diameter and 350 mm (14 in) between centers, with a maximum of 80 kg (176 lb) held between centers. The tailstock quill travels 25 mm (1 in) and takes an MT 3 center.
02
The grinding wheel is Ø455 × 50 × Ø127 mm (Ø18 × 2 × Ø5 in), turning at 1,650 rpm. Supertec states a maximum peripheral speed range of 2,000~3,600 m/min and a wheel spindle motor of 5 kW (6.7 hp).
03
3,100 kg (6,820 lb) net and 3,500 kg (7,716 lb) gross. The packing dimension is 2,970 × 2,250 × 2,250 mm (117 × 89 × 89 in). Hydraulic, coolant and lubrication units are separate from the machine base and need their own floor space.
04
Yes. The G20A-30CNC shares the 5 kW (6.7 hp) wheel motor and 160 mm (6.3 in) infeed travel but swings Ø200 mm (Ø8 in) over 300 mm (12 in) between centers, with a Ø405 × 50 × Ø127 mm (Ø16 × 2 × Ø5 in) wheel at 1,800 rpm.
