Hi-TECH Series

Built to order. Ask for lead time.

Overview

15 / 18 in. box-way lathe, Ø590 x 3,200 mm turning capacity

The Hi-TECH 550 is Hwacheon's 15 or 18 inch heavy duty turning center, built on hand-scraped box ways for hard turning and long workpieces. It comes as the 550A with a 15 inch chuck or the 550B with an 18 inch chuck, each on a standard, long (L) or extra long (XL) bed, and MC versions add a turnmill turret with a C axis. It swings 800 mm over the bed, cuts up to 590 mm in diameter and 1,100, 2,100 or 3,200 mm long, and runs an A2-11 spindle to 2,000 rpm with a 132 mm through hole and 116 mm bar capacity. Spindle power is 30 / 22 kW, and the 10-station turret (12 on MC versions) indexes in 0.2 seconds on a FANUC 0i-TF Plus control.

Features

01Hand-scraped box waysThe guide ways are box ways, hand-scraped and polished to reduce vibration and hold a precise feed under heavy cuts. The long and extra long beds take work up to 3,200 mm.
020.2 second turret indexThe turret indexes in 0.2 seconds per step and takes 32 mm square OD tools and 60 mm boring bars. 10 stations are standard with 12 optional; MC versions carry 12 with live tooling.
03Programmable tailstock standardThe tailstock body positions itself by program and the quill runs by foot switch or program, with 980, 1,980 or 3,080 mm of travel by bed length. A steady rest is optional for long work.
04Optional gearbox for low-speed torqueThe standard spindle motor is 30 / 22 kW. The optional gearbox with a 37 / 30 kW motor gives 3,071 Nm at low speed (30 minute rating), and the gearbox and motor sit away from the spindle to limit heat and vibration transfer.
05Tool load monitoring standardL-HTLD tracks tool load during the cut: at the first limit it holds the feed, at the second it stops the machine. Linear scales on all axes and a tool presetter that sets each tool in under 15 seconds are options.
