Price estimate
We do not have a price for the Drake GS:TE670-750 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 Drake GS:TE670-750 puts the largest swing of the GS:TE external thread grinders on a short bed: 670 mm (26.4 in) over the table with 750 mm (29.5 in) between centers. That shape suits parts that are large in diameter and short, such as thread rolls and rotor components, more than long screws.
It shares its bed length, wheel package and footprint with the GS:TE400-750. The differences in Drake's tables are the swing, which is 400 mm (15.7 in) on the GS:TE400-750, a workholding height of 1.3 m (51.2 in) above the floor, and a weight of 9,850 kg (21,715 lb). The higher work centerline is worth a look if parts are loaded by hand or by an existing gantry.
The wheel spindle row reads 12 kW / 16 kW (16.1 hp / 21.5 hp) at 8,000 rpm, with wheels of ≤400 mm (15.7 in) outside diameter, 10-25 mm (0.4-1.0 in); optional ≤60 mm (2.4 in) wide, on a 160 mm (6.3 in) bore. Dresser rolls are 115-152 mm (4.5-6.0 in) in diameter and up to 32 mm (1.3 in) wide. The workhead nose is A2-8, and there are 4 CNC axes.
Coolant is specified in three rows: 114 lpm @ 7 bar (30.1 gpm @ 101.5 psi) for the grind, 76 lpm @ 2 bar (20.1 gpm @ 29.0 psi) for bed wash, and a total flow of 114 lpm (30 gpm). The total repeats the grind figure, so ask Drake whether bed wash is counted in it before sizing a pump. Discharge is 0.55 m (21.7 in) above the floor. Electrical supply is 200-600 V at 30-45 kVA, and the machine stands on 3.2 m W x 2.6 m D (126.0 in x 102.4 in).

Strengths & Limitations
Strengths
- 670 mm (26.4 in) of swing over the table, the largest in the GS:TE tables
- Same 3.2 m W x 2.6 m D (126.0 in x 102.4 in) floor area as the GS:TE400-750
- Dresser rolls from 115-152 mm (4.5-6.0 in) in diameter
- Optional wheel width of ≤60 mm (2.4 in) for wide forms
- Linear motors and linear roller ways, with rapid return of up to 40 m/min (1,575 ipm)
Limitations
- Length between centers is only 750 mm (29.5 in); long screws need the GS:TE400-2000 at 2,100 mm (82.7 in)
- Workholding height is 1.3 m (51.2 in) above the floor, higher than the 1.2 m (47.2 in) above the floor of the GS:TE400-750
- The total coolant flow row repeats the grind figure, which leaves the bed wash demand unclear
- Lead angle is listed only as variable, with no figure

Frequently Asked Questions
01
Maximum swing over the table is 670 mm (26.4 in), with 750 mm (29.5 in) between centers. Swing is a clearance figure for the part and its fixture; Drake's page does not give a separate maximum grinding diameter for this model.
02
The GS:TE400-750 swings 400 mm (15.7 in), holds the work 1.2 m (47.2 in) above the floor and weighs 9,600 kg (21,164 lb). The GS:TE670-750 swings 670 mm (26.4 in), holds the work 1.3 m (51.2 in) above the floor and weighs 9,850 kg (21,715 lb). Both stand on the same footprint.
03
A diamond dresser roll of 115-152 mm (4.5-6.0 in) diameter, up to 32 mm (1.3 in) wide. Drake's page lists diamond roll truing under standard features for its external thread grinders, though its brochure lists the same item as an upgrade, so confirm what is included.
04
The page lists 114 lpm @ 7 bar (30.1 gpm @ 101.5 psi) for the grind and 76 lpm @ 2 bar (20.1 gpm @ 29.0 psi) for bed wash, and gives total flow as 114 lpm (30 gpm). Coolant discharge height is 0.55 m (21.7 in) above the floor.
05
Approximate weight is 9,850 kg (21,715 lb) and overall dimensions are 3.2 m W x 2.6 m D (126.0 in x 102.4 in). The electrical requirement is 30-45 kVA on a 200-600 V supply.
