How much does the Huron DX 200-7 A cost?
Price estimate
We do not have a price for the Huron DX 200-7 A 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 Huron DX 200-7 A stretches the DX 200 platform to 700 mm (27.6 in) of turning length. With a 365 mm maximum turning diameter and an A2-6 spindle it is a medium shaft lathe on a base that weighs 4,300 kg (9,480 lb).
A longer bed changes the machine more than the capacity table suggests. Length grows to 3,125 mm and width to 1,800 mm, and mass rises from the 3,400 kg of the DX 200-5 A. Huron's stated positioning also moves, from 0.007 mm on the DX 200-5 A to 0.01 mm here, while repeatability holds at 0.005 mm.
Between centres, a 700 mm part needs steady support. The tailstock has an 85 mm hydraulic quill with 120 mm of stroke and up to 500 kgf of thrust. Spindle speed range is 50-4,000 rpm with 13.5/9 kW from the Siemens motor or 11/9 kW from the Fanuc motor. Bar up to 52 mm passes the 70 mm bore.
Tooling is unchanged: an 8-station bi-directional servo turret for 25 x 25 mm shanks and boring bars up to 40 mm. X travel is 200 mm and both axes rapid at 24 m/min. Huron lists efficient chip disposal, which matters more as the bed and the chips per part get longer.

Strengths & Limitations
Strengths
- 700 mm of turning length and Z travel
- 365 mm maximum turning diameter
- 500 kgf tailstock thrust on an 85 mm quill
- 4,300 kg (9,480 lb) machine weight
- 50-4,000 rpm with the A2-6 spindle
Limitations
- Positioning is stated as 0.01 mm, against 0.007 mm on the DX 200-5 A
- Bar capacity is 52 mm; the DX 200-7 B takes 75 mm
- Machine length of 3,125 mm
- Quill stroke is 120 mm, so the tailstock body must be repositioned for different part lengths
