Hwacheon Hi-TECH 700

Heavy duty horizontal turning center

Hi-TECH Series

Built to order. Ask for lead time.

Overview

15 in. geared box-way lathe, Ø680 x 1,986 mm turning capacity

The Hi-TECH 700 is a heavy duty turning center for large workpieces, built on a one-piece 45 degree slant bed with box ways on every guide surface. An automatic transmission gives high torque for heavy turning at low speed and still runs the A2-11 spindle to 1,800 rpm on a 37 / 30 kW motor. It swings 900 mm, cuts up to 680 mm in diameter and 1,986 mm long (1,866 mm on the MC), and passes 116 mm bar through a 132 mm spindle bore. The 12-station turret indexes in 0.4 seconds, a programmable hydraulic tailstock is standard, and the MC adds a turnmill with a C axis.

Features

01One-piece 45 degree slant bedThe bed is a single 45 degree slant casting in fine-grain Meehanite with a heavily ribbed torque tube design, meant to resist twisting and limit heat distortion. All guide ways are solid box ways.
02180 mm spindle bearings, jet lubricatedThe front of the spindle runs on 180 mm double-row cylindrical roller bearings with duplex angular thrust bearings. Jet lubrication and a circulating cooling jacket carry heat away from the spindle.
03Programmable hydraulic tailstock standardThe tailstock body moves by program and the quill by foot pedal or program. Quill diameter is 150 mm with 150 mm of stroke, tailstock travel is 1,878 mm and the center is MT #5.
04Turret disc optionsThe standard turret disc is 135 mm wide and the MC disc 166 mm; a 200 mm wide disc is optional. A VDI 60 turret is also listed as an option.
05Tool load monitoring standardL-HTLD watches tool load during the cut: at the first limit it holds the feed, at the second it stops the machine. A 45 / 37 kW spindle motor upgrade is optional.
