Small laser engraving machine

1. Product introduction:

       Laser cutting of small laser engraving machines is an accurate method of cutting a given material using a CAD file. The parameters of the laser cutting process play an important role in the quality characteristics of the cutting edge. However, lasers have major barriers to their widespread use in conventional material processing, such as beam size limitations, high installation and replacement costs, and expensive fittings that require skilled workers. The researchers studied the effects of different laser parameters on trim quality, cut size, roughness and surface finish. Factors related to the study parameters of this process, such as laser power, spot size and size, and cutting speed versus the size of the resulting incision. We studied the effects of laser power and oxygen pressure on the change in slit width. The cutting quality of the small laser engraving machine is positively related to the cutting speed, power, pulse frequency and cutting speed. The machine can be inserted into five axes simultaneously. This machine is a complex form designed for cutting and its programming is much more complicated than in the case of 2D. Cutting can be performed in two-dimensional (two-dimensional), such as on a metal sheet, or in three-dimensional (three-dimensional) components that require cutting in width, length, and height. The most widely used industrial laser-cut sheet metal is gaseous carbon dioxide, solid Nd:YAG and the nearest fiber. Gas laser CO2 and solid state Nd:YAG lasers have the advantages of low beam power, high efficiency and good beam quality. Fiber has gained too much interest and development recently. In recent years, the application of pulsed yttrium aluminum garnet lasers has become more and more interesting for precision-cut sheet metal due to its high strength, low average beam power, good focusing characteristics, and narrow heat affected zone. Small laser engraving machines are usually better than ordinary laser Nd:YAG lasers Sivarao et al. The CO2 laser system has a fairly good beam with high output power quality enough to meet the requirements of thick section metal cutting.



2. Small laser engraving machine: a machine for cutting high-gloss materials

       High precision and good surface finish. Used to engrave a variety of non-metallic materials, such as acrylic, bamboo products, cloth, plastic, marble, glasses, wood, PVC. Wait for this engraver to process Plessy glassware, acrylic panels, woodcarvings, woodcarving flowers, advertised product advertising products, crystal characters, boxes, models, toys and furniture. The specifications of the laser cutting machine.

Experimental Materials:

       Acrylic acid is a plastic made from one or more acrylic acid derivatives. Polymethyl methacrylate, acrylic acid, or PMMA, due to its special weatherability, is a more widely used acrylic, strength, clarity and versatility. PMMA acrylic sheets have glass-like properties - clarity, gloss, transparency, translucency - in half the weight with up to 10 times the impact resistance. Because it is thermoplastic and softened at very high temperatures, acrylic can form almost any shape. Unbelievably durable, acrylic is a solution for a wide temperature range and has excellent weatherability compared to other plastics.

Experimental details:

       The Taguchi method is a technique for optimizing the process or design of a small laser engraving machine using multiple parameters. Researchers should always be fully aware of the various experimental methods in order to properly experiment and apply them to a single study to maximize efficiency and research results. The complete Taguchi method is actually composed of three main phases, all of which are intended to be offline. These three phases include system design, parametric design, and tolerance design. The parameter design phase of Taguchi is a stage commonly used in research. This stage requires known factors and production should be in progress. The main goal is to improve the performance of the production process by adjusting control factors. Three process parameters were studied: cutting speed (A), feed rate (B), and depth of cut (C). Based on the establishment of an L9 orthogonal array (OA) method, there are nine different experiments.

Why does the engraving machine cast iron bed need to be tempered?

        For the engraving machine that needs to process high strength and high precision, it needs to use cast iron bed. Why does the engraving machine body casting need tempering treatment: steel is the most widely used material in the mechanical industry. The steel microstructure is complex and can be controlled by heat treatment. Therefore, the heat treatment of steel is the main content of metal heat treatment. In order to make the machine tool castings have the required mechanical properties, physical properties and chemical properties, in addition to the rational selection of materials and various forming processes, the heat treatment process is indispensable. In addition, aluminum, copper, magnesium, titanium, and the like can also be modified by heat treatment to obtain different mechanical properties, physical properties, and chemical properties. The overall heat treatment is a metal heat treatment process that heats the cast iron plate, cast iron bent plate or machine bed castings and then cools them at an appropriate speed to change the overall mechanical properties of cast iron platforms, flat plates, cast iron plates or machine bed castings.

     

        Machine tool bed casting products as a large casting must be aged to improve its performance and improve the inherent quality of the bed castings. The overall heat treatment of castings such as machine bed castings, bed columns, and machine table is roughly four basic processes of annealing, normalizing, quenching and tempering. When the casting of the machine bed is tempered, the tempering process should be strictly observed. Supporting ribs should be added to the dense or easily deformed parts to prevent deformation and breakage due to tempering temperature. There should be someone to look after the tempering furnace thermometer to control the temperature in time to prevent the temperature from being too high or too low, which will have a great impact on the tempered workpiece.
