Overview

15 / 18 / 21 in. geared box-way lathe, Ø600 x 3,208 mm turning capacity

The Hi-TECH 650 is a heavy duty turning center for medium-size long shafts and cylinders, with box ways on all guide surfaces, a trapezoidal-section bed and a two-speed gearbox as standard. The 650A runs an A2-11 spindle to 2,000 rpm with 3,071 Nm and a 132 mm through hole; the 650B runs an A2-15 spindle to 1,500 rpm with 4,108 Nm and a 185 mm through hole. Both swing 940 mm and cut up to 600 mm in diameter, and the 650A cuts up to 1,108, 2,108 or 3,208 mm long on the standard, L and XL beds. MC versions add a BMT 75 turnmill with a C axis, and YMC versions add a ±80 mm Y axis for combined turning and milling.

Features

01Two-speed gearbox standardPower reaches the spindle through a two-speed transmission, giving 3,071 Nm on the 37 / 30 kW 650A and 4,108 Nm on the 45 / 37 kW 650B while keeping high spindle speeds available.
02Y axis on YMC versionsYMC versions add ±80 mm of Y travel, which Hwacheon uses for combined turning and milling to cut process time. The turnmill delivers 95.5 Nm, or 140 Nm as an option.
0312-station turret with external coolant passagesThe turret takes 32 mm square OD tools and 60 mm boring bars, and its coolant passages run outside the turret body so coolant cannot leak inside. Hwacheon increased curvic clamp force by 48% in this turret design, and a 200 mm wide disc for long boring bars is optional.
04Front coolant tank, two-stage filteringThe coolant tank sits at the front of the machine for cleaning and pump service, with a two-stage chip filter. A 0.6 MPa pump is standard and 1.5, 3 and 7 MPa pumps are options; tanks hold 250, 300 or 370 L by bed length.
05Hwacheon lathe software standardL-HTLD tool load detection, HLVC vibration control that detects chatter and reduces it automatically, the L-CAL cutting calculator and L-COUNT work and tool counters are standard.
