Production cell with 6 main spindles for flange drivers
Optimised for quantity + flexibility:
- Simultaneous machining of two geometrically identical or different flanges
- Fast, flexible loading of the system by 2 robots
The concept: productivity gain through simultaneous machining of different flanges on one machine bed
The manufacturing cell has an x-axis carrier as its base, on which two machine tables are guided. The tables with their hydraulic clamping elements move the workpiece independently of each other to the positions of the main spindles. These, designed as motor spindles, are arranged in pairs opposite each other and result in 3 machining stations.
At both ends of the x-axis, the raw and finished parts are inserted into/from the clamping devices of the tables. For the greatest possible flexibility in production, the precision machining centre has 4 tool magazines with 12 places each for the external main spindles. All common manufacturing processes are possible: milling, turning, drilling, countersinking, thread cutting, reaming, spindling and many more.
Application – suitable for:
- Flange drivers
- Drive shafts
- Fork flanges
- End machining of shafts, tubes

More InformationHigh cycle rate: loading and unloading
The system is loaded and unloaded via two independent stations:
- One robot is assigned to each of the two work tables.
- The loading and unloading of the hydraulic clamping devices on the two work tables is carried out by the robots at staggered intervals.
- Up to 4 main spindles are engaged at the same time.
Conveyor belts for loading and unloading serve as workpiece storage.

The editing
The manufacturing cell has three machining stations, each with opposing main spindles.
The advantages of the machine concept become apparent: the simultaneous machining of 2 flange drivers on their two cheeks.
Loading/unloading
The clamping device picks up the workpiece to be machined.
Station 1
The machine simultaneously drills two holes “into the solid” (eye holes) on both cheeks of the blank – the blank does not yet have any holes. In addition, both outer plane surfaces are mirrored.
Station 2
The contours as well as an additional groove are precisely introduced into both eye bores with facing slides.
Station 3
The inner diameters of the two bores are reamed.

Production of different workpieces – during operation
Four 12-cavity tool magazines exchange tools with the external main spindles via changing devices in order to produce different workpieces during operation.
The machining of the two eye bores is carried out without tool change with the attachment tools of the facing slide. Diameters from 42 mm to 65 mm can be machined continuously.
