WJA II Type

WATER JET CUTTING CENTER TYPE WJA II

 

LDSA, French leader, Designer and Manufacturer of the Water Jet Cutting Centre, presents its new generation of table type “WJA II” 3, 4 or 5 axis.

Heart of LDSA range, it is compatible with all the options and can evolve in time!

The assembly is driven by a latest generation CNC FANUC (No.1 Global) allowing ease of use and offering a previously unequalled level of Reliability and Precision. The very high pressure water supply (4000B – 6200B), is supplied by a BFT pump (European No. 1)
or KMT (No.1 Global).

The Human/Machine interface is customizable, like the CNC it is fully programmed internally by our Design Office, and managed under Windows 7 PRO. The system is intended to operate autonomously..

The numerous sensors allow control and remote control of the system via a computer network and via the internet.

The equipment is very compact and uses only high quality mechanical and electrical components for increased reliability.

5 AXES FEATURES

Thanks to the new WJAII 5X (3D) and 5X ACTIVE (2.5D) series cutting tables, water jet cutting technology can now extend its range of applications and achieves previously unattainable performance levels.

The main feature of the 5-axis WJAII is the addition of two rotary cutting head movements to the 3 traditional Cartesian axes. The System also uses a probe.

The 5 X/Y/Z/A/C axes are digitised and simultaneous. (A and C drive head rotation and inclination). The useful cutting stroke in Z is increased to 350mm, for increased ergonomics.

In this way, the jet can cut in all directions, the A axis being limited electronically to
45° electronically for safety reasons (+/- 90° possible). This guarantees a high level of precision and also allows the use of the 2D system with the same performance and the same costs as a traditional 3-axis machine.

Finally, the use of the 5 axes allows for automatic angle compensation and perfect geometry, at higher speeds than with a 3-axis model.
