Hi-TECH 850

Extra-Large Horizontal Turning Center

Highly Rigid & Heavy Duty Machining

Hi-TECH 850 is capable of handling a variety of complex jobs from turning to milling in a single process. Its extra-wide and extra-rigid turret, the stability provided by the one piece casting bed and built-in box way design are ideal for turning of large sized workpieces.

  • High-precision powerful turning spindle: 45/37 kW
  • Rigid box way slide design
  • Class leading milling power: 11/7.5 kW
  • Y-axis multiplex machining: 220 mm travel; 10 m/min feedrate
  • Jet lubrication spindle bearing cooling system
  • Boring capacity at ø80×800 mm standard (others on request)

Product Description

Highly Rigid Spindle Design
Hi-TECH 850 has an integrated 45-degree slant bed frame to minimize heat distortion, all guide way are designed as solid Box guide ways to maintain rigidity and precision even during prolonged operations. Its automatic transmission system allows low-speed, high-torque turning as well as high-speed machining, the optional Y-axis ensures process integrated operations of complex large workpieces in one setting.

The largest cutting diameter and cutting length in its class (Ø825/2500/3500/5100 MM)

The spindle, the tailstock and the steady rest system is designed and built to support heavy, large-diameter workpieces. The integrated 45 degree slant bed frame minimizes thermal distortion, all guide ways are in a rectangular box way design, to maintain rigidity and precision even after hours of operation.

Gear-driven Spindle System
The four-speed transmission with the high performance gear decelerator provides extreme high amount of torque at low speed. The bearing assembly is cooled and lubricated by Hwacheon’s unique Oil-Jet cooling system, the gear box temperature is regulated by oil circulation for consistent spindle performance. This four-speed spindle performs best when turning heavy and large workpieces.

Extra-long Boring Bar
Standard maximum diameter / length of the boring bar: D = Ø80 mm / L = 800 mm (others on request).
Maximize your productivity by adding a Y-axis to your Hi-TECH 850 center. This is an ideal option if you want to complete complex processes including turning and milling in a single setting. An added Y-axis will save time and avoid secondary clamping of your part, eliminating down time and increase your profit.

User Friendly Design, A Wide Range of Optional Features
Hi-TECH 850 is designed with the end user in mind. Its user-friendly machine design and a variety of supplementary features ensure a stronger, faster and more precise machining performance.
