How much does the Drake GS:TE240-330MH cost?
Price estimate
We do not have a price for the Drake GS:TE240-330MH 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:TE240-330MH is the external machine in Drake's MH pair of thread grinders: 330 mm (13.0 in) between centers, 240 mm (9.4 in) of swing over the table and 3 CNC axes. Drake describes the MH models as manual helix machines, which points to a wheel head that is set to the lead angle by hand while the CNC runs the grinding axes.
That is the main difference from the GS:TE240-360, which has 4 CNC axes and 360 mm (14.2 in) between centers. The MH machine lists a helix range of ±20°. For a shop that grinds one thread family in long runs, a manually set helix matters at changeover and not during the cycle.
The workhead is the fast part of this machine. Drake lists up to 800 rpm continuous through an A2-6 nose, against up to 300 rpm continuous on the GS:TE240-360. The wheel spindle is rated 12 kW (16.1 hp) at 8,000 rpm, and the form is dressed with a diamond roll 115 mm (4.5 in) in diameter and up to 32 mm (1.3 in) wide. Diamond roll truing, linear motors, a cast polymer base and PartSmart menu-driven screens are all on the handout's feature list.
Check the electrical supply early. The handout lists 380-480 V at 30-45 kVA, where the GS:TE240-360 is listed for 200-600 V. Floor space is 1.9 m W x 2.6 m D (74.8 in x 102.4 in). The handout gives no weight and no grinding wheel size, so those figures have to come from Drake.

Strengths & Limitations
Strengths
- Workhead speed of up to 800 rpm continuous, against up to 300 rpm continuous on the GS:TE240-360
- Wheel spindle rated 12 kW (16.1 hp) at 8,000 rpm
- Lead angle range of ±20°, wider than the ±10° from horizontal of the GS:TEM
- Linear motors, a cast polymer base and diamond roll truing are on the feature list
- Rapid return of up to 40 m/min (1,575 ipm) on a footprint of 1.9 m W x 2.6 m D (74.8 in x 102.4 in)
Limitations
- Manual helix: 3 CNC axes, where the GS:TE240-360 has 4
- Listed for a 380-480 V supply only; the GS:TE240-360 is listed for 200-600 V
- Length between centers stops at 330 mm (13.0 in)
- The handout gives no weight, grinding wheel range or accuracy figure for this model

Frequently Asked Questions
01
Manual helix. Drake calls the MH models manual helix machines, and the table shows 3 CNC axes where the GS:TE240-360 shows 4. The lead angle range is ±20°. If changeover time matters to you, ask Drake how the helix is set and locked on the current build.
02
The handout lists 330 mm (13.0 in) between centers and a maximum swing over the table of 240 mm (9.4 in). Lead is listed as various, meaning it depends on the part and on the grinding process Drake delivers with the machine.
03
Wheel spindle power is 12 kW (16.1 hp) and wheel spindle speed is 8,000 rpm. The standard diamond dresser roll is 115 mm (4.5 in) in diameter and up to 32 mm (1.3 in) wide. The handout does not give a grinding wheel size for this model.
04
380-480 V at 30-45 kVA, and 1.9 m W x 2.6 m D (74.8 in x 102.4 in) of floor. The handout notes that machine specifications are subject to change contingent on part requirements, so confirm the final figures on Drake's proposal for your part.
05
The GS:TI240MH is the internal grinder of the pair, with a maximum internal grind length of 190 mm (7.5 in) and the same 240 mm (9.4 in) swing over the table. Both have 3 CNC axes, an A2-6 workhead nose and a workhead speed of up to 800 rpm continuous. Only the external machine has a stated wheel spindle rating.
