Hwacheon UPR-600B

Ultra-precision roll machining flat-bed horizontal CNC lathe

Built to order. Ask for lead time.

Overview

Ø180 to Ø600 mm rolls, 3,000 mm between centers, linear motor axes

The UPR-600B is Hwacheon's ultra-precision roll lathe, a flat-bed horizontal CNC lathe for machining rolls. Both feed axes run on linear motors to keep vibration down, and the in-house built-in spindle and the feed motors are cooled to limit thermal displacement over long cycles. It turns Ø180 to Ø600 mm with 3,000 mm between centers and carries up to 1,500 kgf, with a least input increment of 0.0001 mm on X and Z. The spindle runs 1 to 300 rpm at 22 / 18.5 kW on a FANUC 31i-B.

Features

01Linear motor axesX and Z run on linear motors (2.4 / 5.3 kW) to keep vibration down, with 15 / 20 m/min rapids.
02In-house built-in spindleHwacheon's own built-in spindle runs 1 to 300 rpm in three automatic ranges at 22 / 18.5 kW on grease-lubricated bearings.
03Cooled spindle and motorsJacket cooling with an oil cooler on the spindle, plus cooling of the feed-axis motors, limits thermal displacement during long runs.
040.0001 mm incrementsLeast input increment is 0.0001 mm on X and Z and 0.0001 deg on C, on a FANUC 31i-B.
05Roll capacityRolls from Ø180 to Ø600 mm, 3,000 mm between centers and up to 1,500 kgf. The spindle has an A2-8 nose and takes a 14 in chuck.
