Price estimate
We do not have a price for the Drake GS:TE400-750 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:TE400-750 is the mid-size external thread grinder of the GS:TE range, with 750 mm (29.5 in) between centers and 400 mm (15.7 in) of swing over the table. It has 4 CNC axes, an A2-8 workhead spindle nose and a wheel spindle listed as 12 kW / 16 kW (16.1 hp / 21.5 hp) at 8,000 rpm.
This is the size at which the range moves from tap and gage work to shafts. The GS:TE240-360 stops at 360 mm (14.2 in), and its workhead nose is A2-6.
Drake's page publishes the coolant side of the installation for this model, which helps when sizing a filtration system. The minimum is 114 lpm @ 7 bar (30.1 gpm @ 101.5 psi) at the grind and 76 lpm @ 2 bar (20.1 gpm @ 29.0 psi) for bed wash. Coolant leaves the machine 0.55 m (21.7 in) above the floor, so a gravity return needs a tank inlet below that level.
Wheels are ≤400 mm (15.7 in) in outside diameter on a 160 mm (6.3 in) bore, 10-25 mm (0.4-1.0 in); optional ≤60 mm (2.4 in) wide. The machine weighs 9,600 kg (21,164 lb) and measures 3.2 m W x 2.6 m D (126.0 in x 102.4 in), with the work held 1.2 m (47.2 in) above the floor. If the part swings more than this machine allows, the GS:TE670-750 offers 670 mm (26.4 in) on the same length between centers and the same floor area.
Supply is 200-600 V at 30-45 kVA. Linear motors on linear roller ways drive the axes, and rapid return is up to 40 m/min (1,575 ipm).

Strengths & Limitations
Strengths
- 750 mm (29.5 in) between centers with 400 mm (15.7 in) of swing
- Coolant requirements are published: 114 lpm @ 7 bar (30.1 gpm @ 101.5 psi) for grinding
- A2-8 workhead spindle nose, a size up from the A2-6 of the GS:TE240-360
- Wheels of ≤400 mm (15.7 in) outside diameter at 8,000 rpm
- Listed for a 200-600 V supply at 30-45 kVA
Limitations
- Swing over the table is 400 mm (15.7 in); the GS:TE670-750 has 670 mm (26.4 in)
- Needs a coolant supply of 114 lpm @ 7 bar (30.1 gpm @ 101.5 psi) plus 76 lpm @ 2 bar (20.1 gpm @ 29.0 psi) for bed wash
- At 9,600 kg (21,164 lb) the floor and the rigging route need checking
- The table lists two wheel spindle powers without saying which is standard

Frequently Asked Questions
01
The length between centers is 750 mm (29.5 in), and the maximum swing over the table is 400 mm (15.7 in). For longer shafts the same swing is available on the GS:TE400-2000, which Drake lists at 2,100 mm (82.7 in).
02
Drake lists minimum grind coolant requirements of 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. The coolant discharge height is 0.55 m (21.7 in) above the floor, which sets how low the return to the filtration unit has to be.
03
Swing. The GS:TE670-750 swings 670 mm (26.4 in) over the table and weighs 9,850 kg (21,715 lb); the GS:TE400-750 swings 400 mm (15.7 in) and weighs 9,600 kg (21,164 lb). Length between centers, wheel package, footprint and electrical supply are the same in Drake's tables.
04
The standard wheel range is ≤400 mm (15.7 in) in outside diameter with a 160 mm (6.3 in) bore. Width is 10-25 mm (0.4-1.0 in); optional ≤60 mm (2.4 in). Wheel spindle speed is 8,000 rpm and the power row reads 12 kW / 16 kW (16.1 hp / 21.5 hp).
05
Overall dimensions are 3.2 m W x 2.6 m D (126.0 in x 102.4 in), at a weight of 9,600 kg (21,164 lb). Workholding height is 1.2 m (47.2 in) above the floor. The electrical requirement is 30-45 kVA on a 200-600 V supply.
