How much does the Chevalier FRG-1000S cost?

Price estimate

Uncertain

We do not have a price for the Chevalier FRG-1000S 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 Chevalier FRG-1000S is the largest rotary surface grinder Chevalier lists, with a hydrostatic turntable of Ø39.4 in (Ø1000 mm) and a table load of 2,644 lb (1,200 kg). Maximum grinding radius is R20.7 in (R525 mm).

It shares its frame with the FRG-800S, and the weights show how little separates them: 14,320 lb (6,500 kg) here, 14,100 lb (6,400 kg) for the FRG-800S. Cross travel is the same 25 in (635 mm) on both. A buyer choosing between the two is really choosing a table, and the larger one costs nothing in travel or spindle.

At this diameter the limits are worth reading closely. Table speed is 10 to 80 rpm. The rim of a part the full width of the table moves quickly at those speeds while the centre barely moves, so finish across the face depends on the control varying the cycle; Chevalier describes an adaptive finish program that adjusts table rotation, infeed speed and grinding wheel speed. Grinding height is 15.7 in (400 mm), enough for rings and plates but not for tall housings.

The spindle is rated 15 hp (11 kW) at 600 to 3,600 rpm and carries a Ø16 in x 2 in x Ø5 (Ø405 x 50 x Ø127 mm) wheel. Wheelhead elevation is 19.7 in (500 mm) at 0 to 12.5 fpm (0 to 3,800 mm/min). The machine runs on the SMART iControl.

Strengths & Limitations

Strengths

Ø39.4 in (Ø1000 mm) table, the largest in the FRG range
2,644 lb (1,200 kg) table load
Grinding radius of R20.7 in (R525 mm) reaches past the table edge
Same 25 in (635 mm) cross travel and 15 hp (11 kW) spindle as the FRG-800S at almost the same weight
Hydrostatic table bearings and in-machine dynamic wheel balancing

Limitations

Maximum grinding height is 15.7 in (400 mm)
Table speed is limited to 80 rpm
Spindle power stays at 15 hp (11 kW) despite the larger table
The maker's floor space row has contradictory inch and metric figures and is not shown

Best For

Rings and plates up to Ø39.4 in (Ø1000 mm) Large rotary tables, chuck bodies and face plates Turbine and pump discs up to 2,644 lb (1,200 kg) Batches of small parts ground together on one large chuck

Frequently Asked Questions

01 How big is the FRG-1000S table?

The rotary table is Ø39.4 in (Ø1000 mm) and is rated for 2,644 lb (1,200 kg). It turns at 10 to 80 rpm on hydrostatic bearings. Maximum grinding radius is R20.7 in (R525 mm).

02 Is the FRG-1000S a bigger machine than the FRG-800S?

Only in the table. Net weight is 14,320 lb (6,500 kg) against 14,100 lb (6,400 kg) for the FRG-800S, and the two list the same travels, spindle and wheel. The FRG-800S table is Ø31.5 in (Ø800 mm) with a 2,204 lb (1,000 kg) load.

03 What control does it use?

The specification names the SMART iControl, Chevalier's own grinder control. The maker lists an adaptive finish program on it that adjusts table rotation, infeed speed and grinding wheel speed for a better finish.

04 How fast do the wheelhead axes move?

The transverse movement (Z) feeds at 0 to 13 fpm (0 to 4,000 mm/min) over 25 in (635 mm). The wheelhead elevation (Y) feeds at 0 to 12.5 fpm (0 to 3,800 mm/min) over 19.7 in (500 mm). Both are driven through ballscrews by servo motors, and the cross feed uses two ballscrews.
