STUDY OF THE TECHNOLOGY OF PROCESSING WOOD MATERIALS WITH THE HELP OF A BAND (METABO) SAW MACHINE IN TECHNOLOGY LESSONS.

Аннотация

This article provides information about the Band (Metabo) saw machine for processing wood. Information is provided about the layout of the band saw machine, safety rules, advantages and disadvantages. Keywords:Bandsaw (Metabo), wood, The main goal of the large-scale work currently being carried out in our Republic to improve the public education and higher education system to a modern level is to create all the conditions for educating the younger generation, improving its quality and efficiency, raising themas loyal children oftheir country and acquiring solid knowledge. A new person is coming of age, a producer who combines physical and mental labor in all respects, with a high professional level and skills, who deeply understands the polytechnical foundations of today's production, and who is able to quickly master the latest machines and technological processes. At the same time, it is necessary to conscientiously demonstrate efficiency and work effectively, so that he himself is inspired and others are pleased with his work. They are cultivating the qualities of creative initiative and activity in work. This allows themto improve boththemselves and theiractions to creative maturity. Based on the concept of the President of theRepublic of Uzbekistan dated October 8,2019, No. PF-5847 “Development of the higher education system of the Republic of Uzbekistan until 2030”, dated October 29, 2020, No. PF-6097 “Development of science until 2030”. Students of the 60111300 technology direction “Technology of processing metal and non-metallic materials” are required to study woodworking technology on modern machine tools. The multi-edged woodworking Bandsaw (Metabo) has two cutting speeds (410 and 880 m/min). This allows you to work with a variety of wood materials. A band saw (Metabo) is a machine that uses band-shaped saw teeth to cut wood into various shapes and angles. It is widely used in furniture production, woodworking, construction, and other industries. Themain parts of aband saw (Metabo) are: Saw band – equipped with steel or primary carbide (bimetallic)teeth; Motor–forrotating theband (0.5–5kW); https://ijmri.de/index.php/jmsi volume 4,issue4,2025 307 Workbench –for mountingthematerial, itis bent using bends; Dustcollector –for cleaning waste from thework process; Tensioningmechanism –ensures thecorrect tension of theband. It guarantees high-quality and accurate cutting of wood materials. A ring guide with three steel rollers at the top and bottom is used to adjust the angle of the saw table, which allows you to perform a wide range of tasks, such as fine-angle cutting. An LED light illuminating the cutting area ensures highaccuracy. A quick-release lever and tool-free door opening allow for quick saw blade changes. The presence of a rotating table extension allows you to work with large workpieces. The asynchronous type motor does not require special maintenance and guarantees low noise levels. A special box for collecting sawdust, as well as an adapter for connecting anexternal suction device, ensure aclean workplace. The Metabo band saw bench is easy to operate with two buttons to start and stop the saw. This makes the control process as easy as possibleforstudents. Theparallel stop issecurely fixed and does notmove during operation, which allows you to process identical workpieces without preliminary markings. The supporting legs of the stand provide the necessary rigidity and stability of the structure, and the wheels provide ease of transportation. Advantages of the band saw (Metabo) - a fine and precise cut compared to other saws, the ability to cut wood of great thickness (up to 300 mm), it is convenient to make curved and complex shapes. Disadvantages - the tape breaks quickly, especially onhard wood. Cuttingmethods Straight cutting – standard work, cutting thick wood, plates and beams. Curved cutting – used in the production of furniture details, decorativeelements. https://ijmri.de/index.php/jmsi volume 4,issue4,2025 308 For maximum cutting quality, high accuracy and stability, the belt should run smoothly due to balanced rollers with rubber coating, and for high accuracy, there should be a fine saw blade guide withthree HSS steel rollers at the topand bottom. The most common and functional woodworking machine in demand among various enterprises working with wood. The main part of the design of the band saw is a closed flexible steel belt with teeth, which in this case is the cutting element. It is located vertically or horizontally. The workpiece is fed to the work table. The tilt of the table allows you to cut at an angle. The machinestart buttonsare located onthebody, which simplifies operation. Upper roller tilt regulator (saw blade adjustment) for band saws. Three HSS steel rollers are located at the top and bottom for high accuracy. The regulator allows you to change the tilt of the upper roller of the band saw. By changing the inclination, the saw blade is aligned so that it iscenter
