Overview

15 / 18 / 21 / 24 in. geared box-way lathe, Ø760 x 4,250 mm turning capacity

The Hi-TECH 750 is a heavy duty turning center for large long shafts and cylinders, with box ways on all guide surfaces, a trapezoidal-section bed and a built-in gear drive that lets it cut at full diameter. The 750A runs an A2-11 spindle to 1,800 rpm with 3,071 Nm; the 750B runs an A2-15 spindle to 1,500 rpm with 6,112 Nm and a 185 mm through hole. Both swing 1,200 mm over the bed and cut up to 760 mm in diameter, and the 750A cuts up to 2,250, 3,250 or 4,250 mm long on the standard, L and XL beds. MC versions add a BMT 85 turnmill with a C axis, and YMC versions add a ±100 mm Y axis.

Features

01Gear-driven spindle, oil cooledThe spindle is gear driven, with oil-jet lubrication for its bearings and gears and an oil cooler as standard. Torque is 3,071 Nm on the 750A (3,735 Nm optional) and 6,112 Nm on the 750B.
02280 mm wide turret discThe 12-station turret disc is 280 mm wide and takes an 80 mm boring bar up to 800 mm long, with a pocket in the cover so the bar clears. Coolant runs through an external block so it cannot leak into the turret.
03210 Nm turnmill, ±100 mm Y axisMC and YMC versions carry an 11 / 7.5 kW turnmill rated at up to 210 Nm and 3,000 rpm on BMT 85 holders. YMC adds ±100 mm of Y travel for off-center milling and multi-face work.
04Programmable tailstock, MT #6The tailstock moves by program and its quill by foot switch or program, with a 160 mm cylinder, 150 mm quill stroke and 2,300, 3,300 or 4,300 mm of travel.
05Heavy bed, separated drive areaThe bed alone weighs 11.6 t on the 4,250 mm model, and the machining area is separated from the feed drives to limit thermal growth.
06Front coolant tank, three-stage filteringThe coolant tank sits at the front for cleaning and pump service, behind a three-stage mesh chip filter. A 0.6 MPa pump is standard with 1.5, 3 and 7 MPa options, and the optional lift-up conveyor raises the chip outlet to 1,200 mm.
