Waterjet PRATICA - Water jet cutting machine with one or two tanks and 3 or 5 axes

The waterjet Pratica has double table and rotating arm (which are both optional) enable to zero downtime for piece loading and unloading (patent pending). This system enables to load the pieces to be machined on one tank in complete safety, while the machine cuts the pieces from the slab on the other tank.

Accessories

1 - Automatic system to evacuate sludge, which is sucked by a centrifugal pump and filtered by a hydro cyclone. 

A piping system with special nozzles (installed on the bottom of the tank) keeps the sludge in suspension.

2 - Head with 5 interpolated axes for inclined cutting, which is required, for instance, to cut the 45° grooves. "C" axis with continuous rotation and "A" axis with inclination of ± 69°.
Provided with ITC function for the continuous automatic compensation of the jet tapering.
In order to get grooves with precise dimensions, the head is provided with an instrument for automatic slab thickness measurement.

 3 - KMT Neoline IV high-pressure pump (30 kW, 3800 bar) with 2 ceramic pistons designed for high pressure, and hydraulic station with radial pistons.
Oil/water intensification ratio: 1:20

Details

4 - The movement accuracy of each single machine is tested and checked through laser and Renishaw ball bar test. 

5 – The cutting unit may be (on request) fitted with a vacuometer, laser pointer and automatic thickness detector.

 

6 - Arm supporting the operating head with precise movement on recirculating ball screws and linear runner blocks.

7 - The device for rotating the arm that supports the operating head guarantees its perfect locking in place.

 

Using MOSAIC™ software (optional) it is possible to select the quantities and different pieces to be inserted in one or more slabs. 

The Automatic Nesting function is much helpful for optimizing production and minimizing waste.

 

 

You can see waterjet Pratica at COVERINGS fair - Orlando (FL) from April 17 to 20.

Breton & Waterjet Corporation

Waterjet Corporation is the well-known Italian company that has been producing for many years water jet cutting machines used in the stone and metal machining fields, the latter being a sector which requires top performances and precision.

In order to complete its range of machines for natural and compound stone processing fabshops, Breton entered into a cooperation agreement with Waterjet Corporation aimed at marketing and supplying their cutting machines, all of which are precise, powerful, fast and offer the possibility of being equipped with a pump of up to 6200 bar.

The optional KMT Streamline PRO 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 square metre is cut down.

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 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).

WaterCad™, is the software specially developed for the 2D processing; it generates simply and quickly any cutting path with a variety of options: automatic looping and tags insertion, automatic standard cut, small bridges for a one-run cut.


Using WaterCad™, it is possible to select the quantities and different pieces to be inserted in one or more slabs. The Automatic Nesting function is much helpful for optimizing production and minimizing waste.
