GRAVOSTAR is a high performance marking head, the smart alternative to conventional engraving that can be easily integrated with robots or other automated processes.
GRAVOSTAR is a high speed etching tool that utilizes an oscillating etching needle principle. Unlike engraving tools, the etching procedure involves no material removal as the process is accomplished by fine point compression of the material.
Powered by compressed air supply, the etching needle begins to oscillate vertically at a frequency of approximately 300 cycles per second which produces marking points that are so closely lined up they cannot be individually recognized. All functional elements of the impulse steering system are integrated in the etching head. Based on the high swinging frequency of the needle, the result is a deepened “continuous” etch line.
The GRAVOSTAR has a marking speed up to 5 metres/min and has integrated height compensation of up to 5 mm to accommodate writing on round or uneven surfaces of practically all materials such as aluminium, coloured metals (anodized etc), tool and high grade steels of different alloys with hardness to about 62 HRC.
Manufactured with renowned Swiss quality and precision, the writing needles can be re-sharpened thus reducing consumable costs.
