Shtrikh 013

TECHNICAL DESCRIPTION

Purpose

The Shtrikh 013 laser engraving system is designed for high precision processing of workpieces with heights of up to 100 mm made of various materials. It provides the ability to apply high-quality raster and vector images to the surface of products. The system can be used for deep and 3D engraving, and also for cutting and perforating thin sheet materials.

The materials used for processing include rubber, sheet plastics (polycarbonate, PVC, ABS), metals, coated metals, paper, cardboard, ceramics, stone, foil, leather and others.

Features

• Shtrikh 013 is equipped with high precision object positioning system that moves the object stage along the X and Y axes. By using this system and applying the method of sequential engraving of image fragments, it is possible to process the workpieces with dimensions of up to 285 × 475 mm. High precision engraving is carried out in automatic mode according to the processing program specified by the operator


• The algorithm of automatic layer-by-layer engraving and the use of a high-precision mechanism for moving the scanning head along the Z coordinate make it possible to form highly detailed 3D images for workpieces made of various metals (steel, brass, aluminum, titanium, etc.)


• Object processing is performed automatically without operator participation. This is especially important when carrying out layer-by-layer engraving of deep 3D images that sometimes lasts for several hours

Operation principle

The system uses fiber ytterbium pulsed lasers of the latest generation with an average radiation power from 20 W to 50 W. These lasers do not require water cooling and periodic maintenance, and are distinguished by high reliability and durability. The pulse repetition rate can vary from 50 kHz to 1000 kHz, which makes it possible to select the optimal processing conditions for a wide range of materials.

Processing of materials in the system is performed by a focused laser beam. Focusing and scanning of the laser beam is carried out using an optical system that contains two galvanometric scanners and an F-θ objective lens (laser head). Shtrikh 013 is equipped with a software-controlled system for moving the laser head along the Z axis, which provides the ability to accurately focus the laser beam and to implement the 3D engraving mode. The minimum movement step is 2 µm.

In the main engraving mode, the laser beam scanning is performed without moving the object stage. In this mode, depending on the objective lens being used, an object area with the size from 50 mm × 50 mm to 175 mm × 175 mm can be processed. If it is necessary to engrave larger images, the original image is divided into fragments, which are engraved sequentially. Shtrikh 013 is equipped with a two-coordinate high-precision positioning system, with the help of which the object stage can move along the X and Y axes at distances of up to 200 mm and up to 300 mm, respectively. Therefore, sequentially engraving fragments of the image and moving the object stage, it is possible to process a workpiece with the size of up to 285 mm × 475 mm.

Flexible workpieces (rubber, plastic, cardboard, etc.) can be fixed on the object stage using a vacuum clamping system.

When processing metals and similar materials, the resolution of up to 5 000 dpi is provided. The system includes a processing center and a control unit with a built-in computer. Control of the system operation and creation of tasks are carried out using a personal computer. The software package supplied with the system provides compatibility with the most popular raster and vector graphic formats (BMP, GIF, JPG, TIFF, PNG and others).
