L5100LY Heavy-Duty Cutting, Large Work Capacity, CNC Turning Center

The L5100LY, Y-axis CNC turning center designed with HYUNDAI WIA's engineering expertise to maximize productivity by enhancing rigidity and accuracy of machining.

Heavy Duty, Large Capacity, Y-axis CNC Turning Center

  • Secures superior rigidity by applying wedge type Y-axis
  • Specialized in heavy cutting by applying 2 Step Gear Box Type Main Spindle (Max. Torque 2,990 N·m)
  • Secures rigidity with box guideways for each shaft
  • Max. Turning Length 2,070 mm Long Bed Structure
  • High-performance Large BMT75 Turret

Y-axis Machining

Secures superior rigidity by applying wedge type Y-axis


1Y-axis Machining

Wedge Type Y-axis Structure

Designed with a compensating Y-axis structure that is fed by the simultaneous operation of the YS-axis and the X-axis, L5100LY features a tool rest of superior rigidity which demonstrates excellent performance for heavy-duty product machining. In particular, off-center machining is available, which is not possible with general lathes, so that high added value products can be manufactured without additional post-processing.


BMT75 Turret

The large 12-station large BMT turret enables the L5100LY to perform high accuracy milling operations in a single setup.
As an option, a 24-angle turret can be applied to increase the tooling range.

  • 12 angles
    Rotation of 30 degrees per side
  • 24 angles
    Rotation of 15 degrees per side

Increased Tool Rest Rigidity

Unlike other holders, the internal holder features a structure which stabilizes two more shafts along the Z-axis, and rigidity along the Z-axis is increased by 5% compared to the previous model.

Gear Driven Spindle For Heavy Duty Cutting



Spindle Ideal for Heavy Cutting

High-precision double-row cylindrical roller bearings and angular contact bearings offer increasement in rigidity of the spindle.
In addition, the two-step gearbox guarantees strong torque at low speed and stable machining capability at high speed.

C-Axis Control

The C-axis can be controlled to 0.001° which makes it possible to process various shapes.


Max. Turning Length 2,070 mm (81.5″)
Max. Turning Dia. Ø610 mm (Ø24″)
Bar Capacity Ø165 mm (Ø6.5″)

Guideway & Tailstock

Structure for Heavy Duty Cutting & Long-axis Machining



Box Guideway

The L5100LY, specialized in machining large products, features box guideways in all axes and gear driven main spindle.
Box Guideways show great performance in offsetting vibrations caused by heavy duty cutting.

Long Bed Structure

L5100LY is designed with a long bed structure with a maximum machining length of 2,070mm, enabling efficient machining of large shafts.

Improved Saddle Rigidity

Rigidity has increased by 23% compared to the previous model by increasing the area of contact between the saddle and the column.

Rapid Traverse Rate (X/Y/Z) 20/12/18 m/min
Travel (X/Y/Z) 360/150/2,120 mm



Large Live-center Tailstock

The L5100LY comes with a standard of tailstock with a large live center of MT#6 and an option of a built-in tailstock of MT#5, enabling stable machining of large or long workpieces.

Quill Dia. Ø120 mm (Ø4.7″)
Quill Travel 120 mm (4.7″)
Tail Stock Travel 2,115 mm (83.3″)
