Our machines create halftone images on any hard surface (stone, glass, metal) by means of mechanical etching with diamond-tipped needles?.
The application of halftone images is performed with the offset method (256 levels of gray), as well as different algorithms for rasterisation. More...
The machine is equipped with a stabilization system which compensates for uneven height of material surface. Also the machine is equipped with electronic automatic mechanism for placing the working gap, which significantly reduces the number of manual operations?.

The machine is installed permanently.Adjustable rubber-metal props are provided for rigid installation.
Prepared workpiece is placed inside the machine on a cart (cart with the rail track is not included in the kit).
The positioning of mechanism is performed by means of ball screw pairs (BSP) with the installation of moving parts on the guiding rails.
Ball screws and guide rails, manufactured by Isel Germany AG (Germany), are characterized by high accuracy, long life, and are easy to maintain.
There is a specially designed control system, which is compact, has low power consumption and high reliability.
The machine is equipped with a stabilization system which compensates for the height of uneven surface.
Also the machine is equipped with electronic automatic mechanism for placing the working gap, which significantly reduces the number of manual operations.
Interface of connectivity to computer - USB is the most affordable at the present time.
Management program works directly under OS Windows® XP/Vista/7. While image is processed on the machine computer can be used in parallel to prepare the next image. Several engraving machines of series Granite can be connected to a single computer (software limit of 15 machines per one computer).
Stability, durability and reliability.
Usage of an industrial pulsed power supply ensures the stability of work of the machine with significant fluctuations of supply voltage.
To perform even a single image the mechanism of machine has to move the engraving head thousands of times. At the same time cables, track energy channels and connectors have significant load. The most important factor for long service of the machine is to use cables specifically designed for use in robotics. Mounted cable connectors of the industrial performance were widely used and applied in the most crucial applications.
Applied track energy releases produced by Igus® (Germany) and Kabelschlepp® (USA) have shown their reliability and durability.
Location of cable runs on the machine is compact, not protruding beyond the outer edge of the machine, this provides an even load, which is a guarantee of their long operating life.
