Helix Y

Helix Series: 2050 Y | 2550 Y

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

Combining turning & milling technologies BFW developed turn-mill version of 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, its 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 build with optimized structural rigidity and stiffness for ultimate performance and consistent results.
Adding Y axes with 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 & achieves production advantage for your competitive manufacturing.
