Overview
24 / 32 in. four-speed box-way lathe, Ø825 x 5,100 mm turning capacity
The Hi-TECH 850 is a 24 or 32 inch chucker for large parts and tough materials, built on a one-piece 45 degree slant bed with box ways on every guide surface. It swings 1,050 mm and turns 920 mm in diameter over a 385 mm length, or 825 mm in diameter over the full 2,500, 3,500 or 5,100 mm cutting length. A four-speed gearbox drives the A2-15 spindle on a 45 / 37 kW motor to 1,500 rpm, with a 185 mm through hole and 164 mm bar capacity. MC versions add a turnmill with a C axis, and YMC versions add a 220 mm (±110 mm) Y axis.

Features
- 01Four-speed gear-driven spindleA four-speed transmission gives high torque at low speed for heavy, large-diameter work. The bearings are oil-jet cooled and the gearbox temperature is held by circulating oil.
- 02825 mm by 5,100 mm turning envelopeThe spindle, tailstock and steady rests are sized to support heavy work: 920 mm diameter over 385 mm of length, or 825 mm diameter over the full 5,100 mm on the XL bed.
- 0380 x 800 mm boring barThe 12-station turret has a 350 mm disc that takes boring bars up to 80 mm diameter and 800 mm long, and indexes in 0.3 seconds per step.
- 04Up to two steady rests (option)As an option, up to two hydraulic steady rests can be fitted, each holding work up to 510 mm in diameter. The programmable steady rest base can be ordered on its own.
- 05Y axis on YMC versionsYMC versions add 220 mm (±110 mm) of Y travel with spindle indexing to 0.0001 degree, so turning and milling of large parts finish in one setup.
- 06Programmable tailstock, tool load monitoringA programmable hydraulic tailstock with a 160 mm quill and MT #6 center travels 2,500, 3,500 or 4,800 mm. L-HTLD tool load detection is standard.
