Overview

Ø5,000 mm ram-type vertical turning on a Ø4,500 mm table

The VT-4500 is a ram-type vertical turning center with a Ø4,500 mm table that cuts up to Ø5,000 mm in diameter and 2,500 mm in length. It is built on an integrated bed with a double-pinion C axis and a 350 mm square milling ram, on box ways on X, Z and W. The table runs 1 to 50 rpm in two steps on a 129 / 105 kW motor and carries 40,000 kgf, and the BT-50 milling spindle runs to 1,500 rpm. Hwacheon lists a Siemens 840D sl control and a machine weight of 140,000 kg.

Features

01Ø4,500 mm table, 40,000 kgfThe table runs 1 to 20 rpm in low range and 21 to 50 rpm in high, with programmable gear change, and carries 40,000 kgf.
02□350 mm milling ramThe ram is 350 mm square with 1,500 mm of Z travel and a BT-50 milling spindle to 1,500 rpm.
032,000 mm cross rail travelThe cross rail moves 2,000 mm on box ways, driven by twin ball screws, and locks with a 20-point hydraulic brake.
04Double-pinion C axisThe table indexes as a C axis in 0.001 degree steps through a double-pinion drive. Hwacheon asks for a technical review with its R&D team before X-C contouring or pocketing.
0512-tool BT-50 ATCThe ATC holds 12 BT-50 tools, with 50 mm square turning tools, tools up to 415 mm long and 100 kgf.
