How much does the Drake GS:TE400-2000 cost?
Price estimate
We do not have a price for the Drake GS:TE400-2000 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:TE400-2000 is the long-bed external thread grinder for screws: 2,100 mm (82.7 in) between centers, for parts up to 400 mm (15.7 in) in diameter. Drake's brochure gives the length as 2,100 mm even though the model name suggests less, so the table is the figure to plan with.
On a shaft this long the travel is what decides cycle time and lead error. The axes are driven by linear motors on linear roller ways, rapid return is up to 40 m/min (1,575 ipm), and Drake states linear positioning accuracy of <0.004 mm (<0.00016 in) over length of travel. Repeatability is <0.002 mm (<0.00008 in). Closed-loop precision feedback is on the brochure's standard list.
The grinding end is the same as on the shorter 4-axis machines. The wheel spindle row reads 12 kW / 16 kW (16.1 hp / 21.5 hp) at 8,000 rpm, for a surface speed of up to 120 m/sec, with wheels of ≤400 mm (15.7 in) outside diameter and a 160 mm (6.3 in) bore. The workhead has an A2-8 nose and turns at up to 300 rpm continuous.
The bed is where the mass goes. This machine weighs 16,000 kg (35,273 lb) and measures 6.5 m W x 2.6 m D (255.9 in x 102.4 in), against 9,600 kg (21,164 lb) for the GS:TE400-750. Electrical supply stays at 200-600 V and 30-45 kVA. Plan the building around the width, the rigging route and the room needed to load a long screw between centers.

Strengths & Limitations
Strengths
- 2,100 mm (82.7 in) between centers for long ball screws and lead screws
- Linear positioning accuracy of <0.004 mm (<0.00016 in) over length of travel is stated over the length of travel
- Linear motor axes with rapid return of up to 40 m/min (1,575 ipm)
- Same wheel package as the shorter machines: ≤400 mm (15.7 in) outside diameter, 160 mm (6.3 in) bore
- Electrical requirement stays at 30-45 kVA despite the longer bed
Limitations
- Needs 6.5 m W x 2.6 m D (255.9 in x 102.4 in) of floor and weighs 16,000 kg (35,273 lb)
- Maximum part diameter is 400 mm (15.7 in); the GS:TE445-4000 takes 445 mm (17.5 in)
- Workhead speed is up to 300 rpm continuous
- Steady rests and other long-part supports are not described in the brochure table

Frequently Asked Questions
01
Drake lists the length between centers as 2,100 mm (82.7 in). That is the distance available for the part between the workhead and tailstock centers with the wheel at zero helix; the ground thread length depends on the part and its drive end.
02
Linear positioning accuracy is <0.004 mm (<0.00016 in) over length of travel and linear positioning repeatability is <0.002 mm (<0.00008 in). The brochure gives the same two figures for every GS:TE machine, including this one.
03
The row reads 12 kW / 16 kW (16.1 hp / 21.5 hp) at 8,000 rpm, with a surface speed of up to 120 m/sec. Wheel width is 10-25 mm (0.4-1.0 in); optional ≤60 mm (2.4 in). The brochure does not say which of the two powers is standard.
04
The GS:TE445-4000 is listed at 4,000 mm (157.5 in) between centers, weighs 32,000 kg (70,547 lb) and has an A2-15 workhead nose. The GS:TE400-2000 weighs 16,000 kg (35,273 lb) and uses an A2-8 nose. Both have 4 CNC axes and the same wheel spindle row.
05
A machine of 16,000 kg (35,273 lb) on 6.5 m W x 2.6 m D (255.9 in x 102.4 in), with the work held 1.2 m (47.2 in) above the floor. Supply is 200-600 V at 30-45 kVA. Coolant figures are not in the brochure table.
