Overview
The Hardinge GS-42 is a 42 mm (1.65 in) bar-capacity CNC lathe with a 12-station VDI turret, X travel of 165 mm (6.50 in) and Z travel of 350 mm (13.78 in). It can run from bar through a 5C or 16C collet, or as a chucker with the listed 6 inch (165 mm) hydraulic chuck, up to 260 mm (10.24 in) in turning diameter.
Look at how the numbers sit against each other. The maximum turning length equals the Z travel at 350 mm (13.78 in), so a part near that length leaves no spare stroke for tool clearance or a long drill. The 260 mm (10.24 in) turning diameter is well beyond what a 6 inch chuck normally grips, so the practical chucking range is smaller than the envelope suggests.
At the spindle the listed figures are 6,000 RPM, 11 kW (15 HP) continuous and 119 Nm (88 ft-lb) through an A2-5 nose. Those are light-cut numbers, matched to bar of this diameter. Collet runout is given as 2.5 microns (0.0001 in) or better.
The machine weighs 3,200 kg (7,055 lb) and rides on hardened and ground box ways, moving in rapid at 20 m/min (787 IPM) in X and 24 m/min (945 IPM) in Z. A Fanuc 0i-TF Plus control is listed. Live tooling, C-axis, tailstock and sub-spindle are not mentioned anywhere in the listed figures, so ask the seller what is fitted and have the rest of the table confirmed at the same time.

Strengths & Limitations
Strengths
- Runs bar up to 42 mm (1.65 in) in 5C or 16C collets, or chucked parts in a 6 inch (165 mm) hydraulic chuck
- 12-station VDI turret, room for a full set of turning, boring and drilling tools on bar work
- Collet runout of 2.5 microns (0.0001 in) or better is listed
- Box ways, hardened and ground, under a 6,000 RPM spindle
Limitations
- Maximum turning length equals the 350 mm (13.78 in) Z travel, leaving no extra stroke on full-length parts
- 119 Nm (88 ft-lb) and 11 kW (15 HP) continuous rule out heavy roughing
- The listed figures do not mention live tooling, C-axis, tailstock or sub-spindle

Frequently Asked Questions
01
It is listed for both. Bar capacity is 42 mm (1.65 in) and the spindle is 5C / 16C collet-ready, which covers bar feeding and collet second operations. A 6 inch (165 mm) hydraulic chuck is also listed, for blanks too large for the spindle, within a 260 mm (10.24 in) maximum turning diameter.
02
Maximum turning length is listed as 350 mm (13.78 in), the same as the Z travel. No tailstock is mentioned in the listed figures, so a slender part of that length would be unsupported at the free end. Stiff, short parts are the safer fit.
03
The turret is a 12-station VDI type. The listed figures do not give the VDI shank size or say whether any stations are driven, so check both on the machine before ordering tool holders.
04
Machine weight is listed as 3,200 kg (7,055 lb). Rapid traverse is 20 m/min (787 IPM) in X and 24 m/min (945 IPM) in Z, on hardened and ground box ways. The spindle tops out at 6,000 RPM.
