LCJET III TYPE

WATER JET CUTTING CENTRE TYPE LCJET III

LDSA, the French leader, Designer and Manufacturer of the Water Jet Cutting Centre, presents its High Precision Model, type “LCJET III” 3 or 5 axes.
The system is based on a homogenous and user-friendly assembly which uses all the current state-of-the-art techniques.

The stainless steel and modular Housing + Chassis are well adapted to the teaching environment and environmental concerns in the workshop!

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 10. 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.

STANDARD CHARACTERISTICS

Cutting speed limited to 20 000 mm/min.
Repeatability: +/- 0.02 mm.
Absolute precision: +/- 0.03 mm.

CHARACTERISTICS 5 AXIS

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

The main feature of the LCJET III 5-axis 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 axis 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 axis A 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.
