Waterjet CLASSICA 5 axis

Hello everybody,
Today I’d like to talk again about Waterjet machines
.These videos showing the machining of two pieces forming a marble chandelier will make you realize how great the potential of Waterjet CLASSICA with 5-axes head is.

The way how it works on curved surfaces is simply amazing! 
Thanks to its 450° rotation around the “C” axis and ±69° inclination on the “A” axis, the Waterjet cutting head with 5 interpolated axes perfectly follows the surface of the piece to be cut.

Numerical control, 3-axes water jet saw to cut marble, granite and compound stone.

- The movement accuracy of each single machine is tested and checked through laser and Renishaw ball bar test. 
- The walls of the tank are made of stainless steel, while its bottom consists of a steel plate 8 mm thick.
- The axes movements are through hardened helical racks and pinions (Alpha Wittestein, Germany) and linear slideways with preloaded bearings (Bosch Rexroth).

- Another optional outfit is the I.T.C.™ system that corrects the natural tapering of the cut by compensating the high pressure water jet through the Numerical Control. The I.T.C.™ system guarantees the realization of top quality products. When the compensation of the I.T.C.™ system is running, the water jet is also directed against the advance direction so as to minimize the so-called “tail effect”, thus reducing the acceleration and deceleration ramps near the corners for a faster and more economical cutting cycle. 
- The optional KMT Streamline PRO 2-60-ISO pump with a maximum pressure of 6200 bar can be supplied as an alternative to the KMT Streamline pump of 4.130 bar. With 6200 bar, other conditions being equal, the cutting speed increases remarkably and the cutting cost per linear metre is cut down.

- Head with 5 interpolated axes for  inclined cutting required,  for instance, to obtain the 45° grooves. C axis with 450° rotation and A axis with +/- 69° inclination. This device can be equipped  with ITC system for automatic  jet tapering compensation and  with continuous rotation.

  Waterjet CLASSICA is available in 3 models:
