Generally, WFL manufactures small as well as big spindles in very precise way on a MILLTURN. In the range of spindle manufacturing especially the machine models M30 MILLTURN to M50 MILLTURN are used. While in the course of the conventional process chain the machining operations turning, deep hole drilling, alignment, milling and deburring have to be carried out in individual operations one after the other, in complete machining in a MILLTURN this process takes place as a single machining operation. Thus, spindle machining in a MILLTURN is characterized by a process saving of 75 %.
Flanx-Spline is suitable for straight or helical shaping of external and internal gears. Conventional slotting tools are used here too, which can be larger, even usable together with prismatic tool holders. The graphically supported programming simplifies use and achieves the same level of quality as special gear shaping machines.
Gear hobbing, i.e. Flanx-Hob, is used for straight and helical external gears (cylindrical or crowned). In addition, Flanx-Hob comes with “radius end”, “conical” and “variable feed” special solutions. Flanx-Hob uses conventional gear hobs - either solid HSS or carbide cutters or with indexable inserted concepts.
Deep hole drilling, gun and ejector drilling with high pressure or high volume coolant supply in axial, radial or inclined position. No need for clamping workpieces into various machines and thereby losing accuracy. Gun drilling with up to 80 bar (1100 psi) and ejector drilling with e.g. 400 l/min (106 gal/min) coolant supply. An important advantage especially for deep hole drilling is the comparatively high performances, torques and feed forces of the drives at 100% duty cycle.
Advantages when manufacturing spindles on a MILLTURN:
- Clamp once - machine complete (including all turning, boring, deep hole drilling and gear cutting processes)
- Fully automated correction of run outs by integrated measurement
- There is no need for multiple clamping which leads to optimised geometric dimensioning and tolerancing
- Process monitoring by WFL iControl
- Automatic loading/unloading
- Optimised coolant supply and pumping process
- Precise results despite use of hard material
- No limit regarding part length
- Automatic tool change
- Highest accuracy & quality
- Balancing holes
- Perfect machine capacity
- Short lead times and set-up times
- Longevity while maintaining precision
