Helix Series: 2050 | 2070 | 2550 | 2570

Helix Series machines are made with single-piece inclined bed cum saddle. They are built with heavy-duty LM guideways for rigidity and precise ball screws for higher accuracy.
The Servo turret of BMT 65 is provided as standard and it is the newest technology for turning mill center for more rigid solutions.
Spindle, turret, and tail stock axes are parallel to each other. It enables higher depth of cut.

Combining turning & milling technologies BFW developed a turn-mill version of the Helix series. Single setup, done-in-one to reduce lead time, achieves component accuracy & maximum efficiency. Ideally suited for a Wide array Of multi-process machining applications.

Helix Turn-mill, options to provide customer flexibility for fixture design to meet demands of cylindrical parts and simple interfacing that allows a wide range of machining applications. Best choice for completely processed prismatic work pieces.
Machines have been built with optimized structural rigidity and stiffness for ultimate performance and consistent results.
Adding Y axes with a Helix turn-mill for off-center operations like drilling, milling, tapping & eccentric boring, etc. Y moment is generated by interpolating to linear axes to increase the linear motion capability & achieve production advantage for your competitive manufacturing.
