How much does the Hyundai WIA HD3100LY/LYA cost?
Estimated price range
Our best estimate for a cnc lathes / turning center in this class — not a quote from Hyundai WIA. Configuration moves it a long way.
Overview
The Hyundai WIA HD3100LY/LYA is a long Y-axis turning centre: 265 / 120 / 1,350 mm of travel in X / Y / Z, a maximum machining length of 1,280 mm and a maximum machining diameter of 420 mm, on a bed set at 30 degrees. Two models share these figures. The HD3100LY takes a 12 in chuck and the HD3100LYA a 10 in chuck.
Set beside the HD3100 Series, the trade is easy to see. Spindle power is the same 26 / 18.5 kW through a belt drive. Z travel goes from the 830 mm (32.7 in) of the HD3100 Series to 1,350 mm, and machining length from the 780 mm (30.7 in) of the HD3100 Series to 1,280 mm. Diameter goes the other way: 420 mm here against 500 mm (19.7 in) on the HD3100 Series.
The Y axis has 120 mm of travel and a 10 m/min rapid, against 24 m/min in X and 30 m/min in Z. A Y axis exists for milling and drilling off the centreline, yet Hyundai WIA's table for this pair states no live-tool speed, so the driven-tool figures have to come from the quotation. The turret holds 12 tools.
Spindle speed and torque are also missing from the table. In the shorter machines the 12 in HD3100 Series lists 1,123 / 657 N·m (828.3 / 484.6 ft-lbf) and the 10 in HD3100A/MA lists 734 / 522 Nm, so it is reasonable to ask whether the LY and LYA divide the same way before choosing a chuck size.

Strengths & Limitations
Strengths
- 1,350 mm of Z travel and 1,280 mm of machining length with a Y axis
- 120 mm of Y travel for off-centre milling and drilling on long parts
- 26 / 18.5 kW belt-driven spindle, the same power the HD3100 Series lists
- Choice of chuck: 12 in on the HD3100LY, 10 in on the HD3100LYA
- 12 tools, where the HD3100 Series lists 10 stations as standard
Limitations
- Maximum machining diameter is 420 mm, less than the 500 mm (19.7 in) of the HD3100 Series
- The Y rapid is 10 m/min, well under the 24 m/min of X and 30 m/min of Z
- The table states no spindle speed, torque or live-tool speed for either model
- No tailstock or steady rest data is given for a machine with 1,280 mm of machining length

Frequently Asked Questions
01
Chuck size is the only difference Hyundai WIA's table shows: 12 in on the HD3100LY and 10 in on the HD3100LYA. Travels of 265 / 120 / 1,350 mm, the 26 / 18.5 kW spindle power, the 12 tools and the rapids are listed once for both. Ask for the spindle speed and torque of each, since the table gives neither.
02
It is longer and has a Y axis. Z travel is 1,350 mm against 830 mm (32.7 in) on the HD3100 Series, and there is 120 mm of Y travel. X travel is 265 mm on both. Maximum machining diameter is 420 mm, where the HD3100 Series turns 500 mm (19.7 in).
03
Maximum machining length is 1,280 mm on 1,350 mm of Z travel, and maximum machining diameter is 420 mm. Parts near full length are slender relative to the chuck, so confirm the tailstock and any steady rest with Hyundai WIA; the table does not list them.
04
24 m/min in X, 10 m/min in Y and 30 m/min in Z. At 30 m/min the carriage covers the 1,350 mm Z stroke quickly enough that tool changes at the far end of a long shaft are not a major part of the cycle. Y moves are short, 120 mm at most, so the lower Y rate costs little.
