Hi-TECH 850BB / BB+
HIGH RIGID BIG BORE TURNING CENTER
Designed For Most Demanding Industrial Applications
The BigBore model (BB und BB+) of the box guideway-based Hi-TECH 550, Hi-TECH 700 and Hi-TECH 850 lathes is distinguished by its extra-large spindle bore (Big Bore), which permits diameters of 190 – 370 mm to be clamped in the spindle. In addition, the BigBore model has a widened turret which has two BMT tool holders, one behind the other. This means that long tools, which are often used for working inside pipes, can be optimally stabilized, significantly reducing vibration. The main spindle can also be equipped with two pneumatic chucks – one in the working space and the other at the rear of the spindle. This allows pipes to be optimally supported in the spindle whilst also being fed in and unloaded from behind.

High Performance Spindle
The performance spindle delivers high torque at low speed, supported by the gear box system. The bearings at spindle assembly are oil cooled, with Hwacheon’s unique Oil Jet Cooling technology; the gearbox temperature is efficiently regulated with the circulating oil coolant for precision results at all time. This spindle system is specially effective for large size, heavy duty jobs especially for oil and gas applications.
High Performance Turret
Entire process from turning to milling can be performed with a single setting. This helps maintain your quality, and eliminates down time in between jobs by getting rid of unnecessary loading and unloading of work pieces. It’s like having two machines in one, which means you’ll be twice as productive.
Multitasking
Run by a powerful AC spindle motor, the turnmill system can accurately axis-index the spindle to perfectly mill, tap, or drill. Different types of milling or turning job can be performed with a single chucking.
User Friendly Design, A Wide Range Of Optional Features
The BB-series of turning centers are designed with end users in mind. Its user-friendly machine design and a variety of supplementary features ensure a stronger, faster and more precise machining performance.
