Overview

Big bore box-way lathe, Ø300 or Ø375 mm spindle bore, Ø920 mm turning diameter

The Hi-TECH 850BB and 850BB+ are big bore heavy duty turning centers for large pipe and long shafts, on a 45 degree slant unibody bed with box ways on all guide surfaces. The 850BB has a 300 mm spindle through hole with 295 mm bar capacity to 1,000 rpm; the 850BB+ opens to 375 mm with 370 mm bar capacity to 750 rpm, both on A2-20 noses driven by a 45 / 37 kW motor through a gearbox. They swing 1,050 mm, cut up to 920 mm in diameter, and come with 2,650, 3,650 or 5,250 mm of Z stroke. MC versions add a turnmill with a C axis, and YMC versions add a 220 mm Y axis.

Features

01300 or 375 mm spindle boreThe 850BB passes bar up to 295 mm through a 300 mm bore; the 850BB+ passes up to 370 mm through a 375 mm bore on 440 mm bearings.
02Up to 8,590.7 Nm in low gearThe 850BB gives 4,694.4 Nm up to 341 rpm in low gear and the 850BB+ 8,590.7 Nm up to 200 rpm (30 minute ratings). Bearings are oil-jet lubricated and the gearbox is oil cooled.
03Chucks at both ends of the spindleOptional air chucks mount in front of the spindle, 630 mm on the 850BB and 850 mm on the 850BB+, and optional 24 or 28 in. manual chucks at the rear, so long pipe is held at both ends.
0480 x 800 mm boring barThe 12-station turret uses a wide disc as standard, takes boring bars up to 80 mm by 800 mm and indexes in 0.3 seconds per step.
05Y axis on YMC versionsYMC versions add 220 mm (±110 mm) of Y travel, and the 11 / 7.5 kW turnmill delivers 210 Nm (30 minute rating), so turning and milling finish in one setup.
06Loading from the rear, thread repairThe side cover opens so hoist-lifted parts can be loaded from the rear of the spindle. Manual Guide i includes a thread repair function, and L-HTLD tool load detection is standard.
