How much does the Drake GS:DS cost?
Price estimate
We do not have a price for the Drake GS:DS 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:DS is a dual spindle grinder: one machine with an external grinding spindle and an internal grinding spindle, and 5 CNC axes. Drake's case for it is that several operations are ground in one fixture setup, so threads stay aligned to the other ground datums of the part.
The external side resembles a short GS:TE machine. It has 360 mm (14.2 in) between centers, 580 mm (22.8 in) of swing and a wheel spindle listed as 12 kW / 16 kW (16.1 hp / 21.5 hp) at 8,000 rpm, with wheels of ≤400 mm (15.7 in) outside diameter on a 160 mm (6.3 in) bore. Its helix range is ±30° from horizontal.
The internal side uses wheels of ≤100 mm (3.9 in) outside diameter and 5-20 mm (0.2-0.8 in) wide, with 560 mm (22.0 in) of swing. Its lead angle range is +25° / -30° from horizontal, and its spindle power is listed as various. Both sides share an A2-8 workhead and dress with diamond rolls of 115-152 mm (4.5-6.0 in) diameter.
All of this fits the footprint of a single internal grinder: 2.2 m W x 2.7 m D (86.6 in x 106.3 in), at 7,300 kg (16,093 lb). The part is not re-chucked between the internal and external operations, which removes one source of runout between them. The cost is a more complex machine and process. Supply is 200-600 V at 45 kVA, and the work is held 1.2 m (47.2 in) above the floor.

Strengths & Limitations
Strengths
- External and internal grinding spindles in one machine with 5 CNC axes
- Multiple operations in one fixture setup, which Drake says improves alignment of threads to other datums
- External helix range of ±30° from horizontal
- Footprint of 2.2 m W x 2.7 m D (86.6 in x 106.3 in), the same as a GS:TI280
- External wheels of ≤400 mm (15.7 in) outside diameter at 8,000 rpm
Limitations
- External length between centers is 360 mm (14.2 in); the GS:DS-1000 is the longer version
- Internal wheel spindle power is listed only as various
- Internal lead angle range is asymmetric: +25° / -30° from horizontal
- No workhead speed or accuracy figure appears in the table

Frequently Asked Questions
01
The machine carries two grinding spindles, one for external and one for internal work, and Drake's table gives a column of figures for each. With 5 CNC axes it can grind several operations on a part in one fixture setup.
02
Length between centers is 360 mm (14.2 in) and swing over the table is 580 mm (22.8 in). The wheel spindle row reads 12 kW / 16 kW (16.1 hp / 21.5 hp) at 8,000 rpm, with a wheel width of 10-25 mm (0.4-1.0 in); optional ≤60 mm (2.4 in).
03
Swing over the table is 560 mm (22.0 in). Standard wheels are ≤100 mm (3.9 in) in outside diameter and 5-20 mm (0.2-0.8 in) wide, and the lead angle range is +25° / -30° from horizontal. Spindle power and wheel bore are listed as various.
04
Overall dimensions are 2.2 m W x 2.7 m D (86.6 in x 106.3 in) and approximate weight is 7,300 kg (16,093 lb). Workholding height is 1.2 m (47.2 in) above the floor. The electrical requirement is 45 kVA on a 200-600 V supply.
05
The GS:DS-1000 has 1,000 mm (39.4 in) between centers and weighs 19,000 kg (41,887 lb). The GS:DS has 360 mm (14.2 in) and weighs 7,300 kg (16,093 lb). Wheel ranges, workhead nose and axis count are the same in both tables.
