Overview
Ø1,200 mm swing over bed, 3,000 to 6,000 mm between centers
The MEGA+120 is a flat-bed horizontal CNC lathe for large shaft work such as main shafts and large-diameter pipe in shipbuilding, wind power, aerospace and general industry. It has a 2-way bed with integrated saddle and tailstock ways and a high-rigidity box-way feed system, and Hwacheon designed it to keep thermal displacement low over long runs. Swing over bed is Ø1,200 mm, distance between centers runs 3,000 to 6,000 mm, and the spindle takes an 18 inch chuck with a Ø155, Ø255 or Ø320 mm bore. It runs on FANUC 0i-TF Plus or SIEMENS 828D.

Features
- 012-way flat bedOne bed with two ways carries the saddle and the tailstock on integrated ways. Bed width is 700 mm and bed length runs 5,410 to 8,410 mm across the four lengths.
- 02Box-way feedHwacheon uses a high-rigidity box-way feed system for heavy cutting. X travels 625 mm, rapid traverse is 6 m/min on X and Z (5 m/min Z on the 6000), and cutting feed reaches 3,000 mm/min.
- 03Three spindle boresØ155 mm (A2-15, 5 to 750 rpm, No.170 metric taper), Ø255 mm (A2-15, 5 to 650 rpm, No.260) or Ø320 mm (A2-20, 5 to 400 rpm). Speed ranges shift automatically in 3 steps.
- 04Built-in tailstockThe tailstock has an Ø200 mm quill, MT No.6 taper and 260 mm of quill travel.
- 054-way manual tool postA 4-station manual tool post takes □32 mm tools. Swing over the cross slide is Ø840 mm.
- 06FANUC or SIEMENSHwacheon lists FANUC 0i-TF Plus and SIEMENS 828D. The spindle motor is 45 / 37 kW with FANUC and 55.5 / 37 kW with SIEMENS.
