A Brief Explanation of Principles and Mechanisms<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Laser processing is a processing method for drilling and cutting by irradiating a laser beam generated by a laser oscillator or other processing machine onto a material.<\/p>\n\n\n\n<p>The principles of this process are directivity (directivity) and monochromaticity.<\/p>\n\n\n\n<p>Because lasers are highly directional and monochromatic, they generate high-density energy when focused by a lens or other means.<br>Materials such as metals can be processed by converging lasers in a dedicated processing machine and irradiating high-density energy onto the material.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\"

oscillator.<\/p>\n\n\n\n<p>Different types of materials are suitable for different types of processing, so it is important to select the appropriate one.<\/p>\n\n\n\n<p>The features of each type used in laser processing are summarized below.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Types of Lasers<\/td><td>feature<\/td><td>Target materials and

processing machine<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The following is a list of the main laser processing machines used for laser processing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Laser oscillator system<\/h3>\n\n\n\n<p>A laser oscillator system is a device for oscillating light.<\/p>\n\n\n\n<p>An excitation light source such as a lamp is irradiated onto a medium such as an individual or gas, and the light is repeated by mirrors in a resonator to emit light as a laser.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">process optics<\/h3>\n\n\n\n<p>The processing engineering system is used to focus the laser generated by the laser oscillator and irradiate it to the table.<\/p>\n\n\n\n<p>There are two main types: one that uses reflective mirrors and the other that uses optical fibers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Processed material system<\/h3>\n\n\n\n<p>The process material system consists of the table on which the workpiece is fixed and the workpiece itself.<\/p>\n\n\n\n<p>In laser processing, the following engineering and thermal properties affect the workmanship of the workpiece.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reflectance of workpiece<\/li>\n\n\n\n<li>Absorption rate<\/li>\n\n\n\n<li>transmittance<\/li>\n<\/ul>\n\n\n\n<p>The processing material system is responsible for controlling the light collector system and Taevil and setting the appropriate speed, which is necessary when processing while moving the irradiation position.<\/p>\n\n\n\n<p>There are two types of processed material systems<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>system<\/td><td>feature<\/td><\/tr><tr><td>staged<\/td><td>The laser is fixed

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>This section explains the various advantages of laser processing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">High processing efficiency<\/h3>\n\n\n\n<p>Laser light has higher energy than other heat sources used in thermal processing and has the advantage of speedy processing due to its high heat input efficiency.<\/p>\n\n\n\n<p>Compared to other processing methods, cutting, surface treatment, and other processing speeds are faster, leading to increased efficiency in overall processing operations.<\/p>\n\n\n\n<p>No dies are required for cutting as in press cutting, eliminating the need for die replacement and management.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Complex processing and high flexibility in processing<\/h3>\n\n\n\n<p>In addition to using graphic data, laser processing enables fine and complex processing by adjusting irradiation position and power.<\/p>\n\n\n\n<p>Specifically, the following processing is supported<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>processing method<\/td><td>feature<\/td><\/tr><tr><td>Laser Removal<\/td><td>A process in which an object is melted by heat, blown away, or otherwise evaporated by high energy in a short period of time. It can cut materials, make holes, and engrave designs.<\/td><\/tr><tr><td>laser welding<\/td><td>A process for joining heated metals and resins by melting them. We support overlap welding, butt welding, and other welding methods.<\/td><\/tr><tr><td>Laser Modification<\/td><td>Processes include quenching, annealing, marking, and cladding, in which the surface of a material is heated and cooled rapidly to change its surface composition and improve its properties.<\/td><\/tr><tr><td>Laser deformation<\/td><td>Bending process using thermal stress of irradiated material. Requires advanced technology.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Because the laser beam is narrow, the laser is also good at fine processing other than cutting.<\/p>\n\n\n\n<p>For example, it is possible to drill holes in fine areas that are not possible with other processing methods, reproduce complex kanji characters and fine patterns, and process complex curves.<\/p>\n\n\n\n<p>It is used not only for finishing, but also for applying a rust-resistant finish to the surface.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Various materials can be

post-processing such as polishing to remove burrs and chips is also unnecessary.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Hassle-free maintenance of processing machines<\/h3>\n\n\n\n<p>In laser processing, there is no contact between the material and the tool during processing.<\/p>\n\n\n\n<p>Therefore, there is no wear and tear on knives, tools, grinders, etc., as with other processing methods, and the advantage is that maintenance is less time-consuming.<\/p>\n\n\n\n<p>No dust or chips will be generated when cutting materials, which will save time and effort in removal.<\/p>\n\n\n\n<p>The only maintenance required is simple, such as cleaning mirrors and lenses, cleaning assist air, etc.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>While laser processing has some advantages, it also has disadvantages.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Many materials cannot be processed.<\/h3>\n\n\n\n<p>In some cases, the following materials cannot be laser processed.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Thick material<\/li>\n\n\n\n<li>Highly reflective material<\/li>\n\n\n\n<li>Materials that generate hazardous substances<\/li>\n<\/ul>\n\n\n\n<p>This is because thicker materials tend to move away from the focal distance of the laser beam, reducing its power and making it impossible to process.<\/p>\n\n\n\n<p>In addition, highly reflective materials such as copper and aluminum will repel laser light.<br>However, by selecting the appropriate laser processing machine, it may be possible to process even highly reflective materials.<\/p>\n\n\n\n<p>Other materials that cannot be processed include polyvinyl chloride, which emits toxic gases when exposed to laser beams, and Teflon and fluorine, which emit toxic substances.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Slightly higher processing costs<\/h3>\n\n\n\n<p>In addition to the cost of the processing machine itself, the following costs are incurred for laser processing.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>electric utility expense<\/li>\n\n\n\n<li>gas money<\/li>\n\n\n\n<li>Consumables such as focal lenses and mirrors<\/li>\n<\/ul>\n\n\n\n<p>In addition to being expensive, laser processing machines with high-performance laser oscillators and controllers incur many running costs.<\/p>\n\n\n\n<p>Therefore, it is more cost-effective to hire a processing company than to install processing equipment in-house.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Processing takes time<\/h3>\n\n\n\n<p>Laser processing is a method of processing materials by pinpoint irradiation and melting them.<\/p>\n\n\n\n<p>Compared to other processing methods such as pressing and cutting, machining takes longer.<br>Note that although increasing the power increases the cutting speed of the laser cutting machine, it also increases the tendency for burrs and dross to occur.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"%E3%81%BE%E3%81%A8%E3%82%81\"><\/span>Summary<span
