Mega III

Built to order. Ask for lead time.

Overview

Ø2,000 mm turning diameter, 6,000 to 17,000 mm between centers

The MEGAIII-200 is the middle model of Hwacheon's Mega III heavy-duty flat-bed lathes, built for large shafts, pipe and turbine parts in shipbuilding, wind power, aerospace and general industry. Its 2,000 mm wide 3-way bed carries the saddle and a geared-motor tailstock on separate box ways. It swings Ø2,050 mm and turns Ø2,000 mm, with 900 mm of X travel and 6,000 to 17,000 mm between centers, and carries 25 tons (40 optional). The spindle drives a 63 in chuck at 1 to 130 rpm through three automatic ranges, with 136 / 92 kW and 12,713 kgf·m of torque, on a Siemens 828D.

Features

013-way bed with separate waysThe 2,000 mm wide 3-way bed carries the saddle and tailstock on separate ways. It comes apart into units for easier connection, and its vertical chip drop eases chip removal and fitting a chip conveyor.
02Spindle drive12,713 kgf·m at 136 / 92 kW and 1 to 130 rpm on the standard 25 ton build, which drives the spindle by V-belt. The optional 40 ton build comes with a V-belt or direct drive.
03Geared-motor tailstockThe built-in tailstock travels by rack and pinion on a geared motor, with 3-point support and double safety equipment. It has a Ø450 mm quill (Ø600 mm optional), a Ø160 x 75° dead center and 300 mm of quill travel.
04Tailstock load meteringA tailstock load meter is standard. The optional extra operating panel with a load cell measures the work's axial thrust to set clamping force and protect the tailstock drive.
05Feed drivesX runs on a direct ball screw. Z uses a ball screw below 8,000 mm and a ball screw or rack and pinion above 8,000 mm.
06Control optionsA Siemens 828D with a 10.4 in display is standard. Sinumerik One, FANUC 0i-TF Plus and FANUC 32i-B are options, along with X / Z linear scales.
