Germany

The VARIOGRAV is a machine for large Area Laser Engraving of 2D and 3D pictures inside transparent materials as glass or plastic.
The technical concept is based on the design of VARIOPLOT. The Tool Head is a diode pumped ND YAG Laser with a Galvo Head which deflects the laser beam in a high speed and focuses it inside the surface of the transparent material. Optionally the laser tool head can be exchanged against a Milling Head. This Tool Head gives addition possibility of Milling Surfaces of plastic.

Main Applications:

• Large Scale Engraving of 2D and 3D samples in transparent materials
• Engraving of window elwments
• Engraving of Glass Cubes
• Engraving of transparent fassades
• Engraving of Table Tops, Desks, Design Elements in the Furniture Industry
• Engraving of Advertising Material with 2D or 3D pictures of machines etc.
• Engraving of different 3D information as for instance technical drawings from architects for 3D visualization
• Engraving of transparent Advertising plates
• Gifts

Standard Sizes

Width: 1,3 m; 1,6 m; 2 m
Length: 1 m; 1,7 m; 2,3 m; 3m
Each width can be combined with each length
For instance VARIOGRAV 1317; Working Area: 1,3 m x 1,7 m

Main Features of the VARIOGRAV

Machine:

Controlled z-Axis; Tool Heads easy to exchange within 30 sec; Table Surface can be machined by Milling Module for extremely flatness; Space for material thickness up to 60 mm; excellent dynamic

Vacuum System:

High efficient vacuum zones with multiple connections and Pressure Balancing System (PBS)

Control System:

2 PC for machine control and Data Base

Automatic Tool Measuring

Tools are automatically measured and referenced with respect to length in the case of optional Milling Tool.

Service Concept

Easy to exchange Modules enable the operator to exchange function groups by himself.

Process

The ND YAG Laser Beam is generated in a diode pumped module and guided to the mirrors of an integrated galvo head. The mirrors deflect the beam in x and y direction at high speed and focuses the laser beam inside the transparent material. Image dots are generated inside the transparent material. The combination of the high speed deflection in x and y axis for short distances and the movement of the machine axis in x y and z direction for large distances creates large scale 2D or 3D pictures inside the transparent material. Illumination of the transparent material increases the visual brilliance of the engraved pictures.

RSAS

Remote Service and Analysing System RSAS gives the advantage of immediate support via the internet connection.
Varioplotter is delivered also with a camera System which provides the possibility of visual inspection over big distances.

The Control System

• Import of CF2 and DXF Files as well as BMP files, LAS files etc. JPEG Files of digital cameras can be modified and exported by external programs
• Nesting of different files: Multi Import of different files, Rotation in steps of 90 degrees, linear Movement.
• Flexible Setting of Line Types and Tools.
• Flexible Parameter Setting for Laser Operation
• Step and Repeat Process
• Enter of real material size for easy positioning of files
• Data Base for different Material / Customers for easy reproduction of parameters.
• Simulation of the Process
• RSAS: remote Service and Analysing of the complete System by Internet, software upgrades.
• Manual Movement of axis, Setting Zero Point at different positions
