12 | TRANSTURN TT312 Wirth et Gruffat

12 stations
Turret equipped with 12 electrospindles
22 cross slides with numeric control
Logic control : SIEMENS
Total turret indexing in 1,35 sec.
Indexing precision : +/- 3"
Complete machining
- Automatic feed from bar or with robot
- All conventional second operations such as milling, drilling, tapping ...
- Turning with "part revolving" (10 kw spindle)
Precision
- Turret positioning secured by treble Hirth crown coupling
-Tool slides on ball bearing sliding plates, movements controlled by NC
and absolute encoder.
- 3-segrnents clamping (chuck or collets)
- Integrated refrigeration system for spindles and coolant
- C-axis
- No need for correcting operations : accurate concentricity and perfect face of reference
Productivity
- Global indexing time : 1,35 sec.
- 22 simultaneous machining operations minimum
- High turning power
- The ergonomy of the machine makes the tools changing easier
- No more intermediate operations hence no more intermediate stocks
Flexibility
- All tool slides are identical and have beendesigned to accept
fixed and rota ring tools (see our rangr of W&G quills)
- Reduced setting times
- Intergangeable clamping devices
User-friendliness
- Of the numeric control
- Of the change of series of parts
- Of the maintenance work :
- With handheld console for NC control
- With specific design of the doors to be leakproof and also drip free when opening
to a great accesibihty of the inner elements of the machine
