Overview

Ø2,000 mm ram-type vertical turning on a Ø1,650 mm table

The VT-1650 is a ram-type vertical turning center with a Ø1,650 mm table that cuts up to Ø2,000 mm and 1,300 mm high, and takes workpieces up to 1,800 mm tall. Hwacheon builds it for heavy machining of large parts in shipbuilding, wind power and plant work, on an integrated column with box way guides on X, Z and W. The geared table runs to 250 rpm on 45 / 37 kW with 27,587 Nm and carries 10,000 kgf. The MC version adds a 26 / 22 kW BT-50 milling spindle to 3,000 rpm and a C axis indexed to 0.001 degree, for turning and milling in one setup.

Features

01□250 mm milling ramThe ram is 250 mm square with 1,000 mm of Z travel. Turning tools clamp on a curvic coupling with four pull studs.
02Ø1,650 mm geared tableThe table runs 1 to 64 rpm in low range and 65 to 250 rpm in high, with programmable gear change. It delivers 27,587 Nm and carries 10,000 kgf on thrust ball and cylindrical roller bearings.
03Moving cross railThe cross rail travels 800 mm on Turcite-lined box ways, driven through twin ball screws under NC servo control (5.5 kW W-axis motor), and locks with a 4-point hydraulic brake.
04Turning and milling in one setupThe MC version adds a 26 / 22 kW BT-50 milling spindle to 3,000 rpm and a C axis with a zero-backlash double pinion drive, indexed to 0.001 degree.
0516-tool ATC, angle head optionA drum ATC holds 16 BT-50 tools as standard, and Hwacheon lists 24 and 34-tool magazines as options. The optional angle head is changed automatically by the ATC.
