In case of bevel cutting, applications from 35 \u2013 40 mm thick tend to be the limit for plasma already: thicker mild steels are traditionally bevel cut by oxyfuel triple torches which allow making two or three cuts at once, creating Y, X or K&nbsp;cut edges in one go. Triple torch technology has certain drawbacks though \u2013 the geometry of the torch setup doesn\u2019t allow cutting some types of contours (especially internal beveled edges), the bevel angle is limited to max. 50\u00b0 and, overall, the maximum material thickness for bevel cuts is usually limited to 80 \u2013 100 mm, making it suitable just for certain applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To overcome these limitations, MicroStep came up with an elegant solution: why not integrate an oxyfuel torch into the company&#8217;s&nbsp;existing rotary bevel head design and enjoy the already developed and established features from plasma also for oxyfuel?<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/hqVpbz-f102-52490-1024x768.jpg\" alt=\"\" class=\"wp-image-5696\" style=\"aspect-ratio:16\/9;object-fit:cover\" srcset=\"https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/hqVpbz-f102-52490-1024x768.jpg 1024w, https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/hqVpbz-f102-52490-300x225.jpg 300w, https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/hqVpbz-f102-52490-768x576.jpg 768w, https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/hqVpbz-f102-52490.jpg 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Oxyfuel triple torches make K-cuts in one go but lack the ability to cut really thick (Italy)<\/figcaption><\/figure>\n<\/div><\/div>\n\n\n\n<div style=\"height:var(--wp--preset--spacing--80)\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading has-text-align-center\"><strong><strong>Introducing the oxyfuel rotator<\/strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The MicroStep rotator is a&nbsp;5-axis 3D bevel head with endless rotation and a&nbsp;tilt up to 52\u00b0 (for plasma torches) that has proven itself in hundreds of installations worldwide. Thanks to the torch pivot point being aligned with its rotary axis, the design is well suited for cutting a&nbsp;great range of bevel shapes including internal contours, variable bevels as well as multiple bevel contours Y, X or K. For oxyfuel, the head has been modified to include an endless gas transmitter, a&nbsp;tactile height measurement system and, most significantly, the torch tilt was increased to 67\u00b0 which allowed to make use of the generally narrower and pointier oxyfuel torch for cutting material at bigger angles. Compared to triple torch cutting, the advantages are obvious: maximum material thickness for direct beveling increased above 120 mm (depending on application and bevel angle even up to 200 mm), the cut angle increased to a&nbsp;full 0\u00b0 \u2013 60\u00b0 range compared to the 20\u00b0 \u2013 50\u00b0 range for triple torch. The AC geometry of the bevel head allows to cut significantly smaller radiuses on holes and internal contours, e.g. for thick pipe intersections. Furthermore, oxyfuel rotator with an integrated laser scanner can use Additional Beveling Process (ABP) which greatly expands the possibilities of beveling thick sheets on a&nbsp;cutting machine.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-style-default\"><img loading=\"lazy\" decoding=\"async\" width=\"1280\" height=\"720\" src=\"https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/PznxFx-f102-52491.jpg\" alt=\"\" class=\"wp-image-5697\" srcset=\"https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/PznxFx-f102-52491.jpg 1280w, https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/PznxFx-f102-52491-300x169.jpg 300w, https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/PznxFx-f102-52491-1024x576.jpg 1024w, https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/PznxFx-f102-52491-768x432.jpg 768w\" sizes=\"auto, (max-width: 1280px) 100vw, 1280px\" \/><figcaption class=\"wp-element-caption\">Advantages of additional beveling with oxyfuel \u2013 minimum waste, smooth cut surfaces, precise cut contours also for bigger bevel angles, as showcased on the above parts 90 mm thick, Y cut with land size 20 mm, bevel angle 60\u00b0, cut with MicroStep ABP technology for a&nbsp;South African customer<\/figcaption><\/figure>\n<\/div><\/div>\n\n\n\n<div style=\"height:var(--wp--preset--spacing--80)\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n<h2 class=\"wp-block-heading has-text-align-center\"><strong><strong><strong>Multiple material and gas savings with ABP<\/strong><\/strong><\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The principle of additional beveling is that the part is firstly cut straight, afterwards it is taken out of the sheet, placed on a&nbsp;free spot on the cutting table, scanned for exact contour\/position and, subsequently, bevel cuts are added to the contour. For oxyfuel this means that really thick parts (~250 \u2013 300 mm) can be produced with clean bevels with angles ranging up to 60 \u2013 65 degrees \u2013 with great saving of gas and material. For Y or K&nbsp;cuts, with ABP the effective bevel cut thickness is significantly smaller compared to direct beveling into a&nbsp;full sheet, which allows to cut bevels much faster and with multiple saving of the cutting gas. Higher cutting speeds also mean that there is a&nbsp;smaller heat-effected zone in the material, i.e. better quality of the final part. The necessary additional part handling times with ABP can be offset by having a&nbsp;machine with multiple straight gas torches, and using ABP on multiple parts in one sequence.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"412\" src=\"https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/yGWt6Q-f0-52493-1024x412.jpg\" alt=\"\" class=\"wp-image-5698\" srcset=\"https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/yGWt6Q-f0-52493-1024x412.jpg 1024w, https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/yGWt6Q-f0-52493-300x121.jpg 300w, https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/yGWt6Q-f0-52493-768x309.jpg 768w, https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/yGWt6Q-f0-52493.jpg 1306w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Comparison of direct and additional beveling: Same part with K-type edge profile, cut directly (DBP) into full sheet, produces much more material waste around the part (displayed in pink color), and additionally the effective cut thickness is much bigger which means far greater gas consumption, slower cutting, and bigger heat affected zone around the cut edge. In this case, ABP has clear advantage&nbsp;<\/figcaption><\/figure>\n\n\n\n<div style=\"height:var(--wp--preset--spacing--80)\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Secondly, with ABP there is no additional material waste from the unused part of the bevel cuts because the beveling is done on an already cut contour with no material around it. This presents a&nbsp;significant material saving especially for bigger thicknesses and higher bevel angles. Not to mention that compared to other methods of additional beveling \u2013 e.g. using one cutting machine for straight cutting and a&nbsp;separate robot workplace for beveling \u2013 the use of one machine for all operations is much more efficient and comes with much lower initial cost. A&nbsp;real case study from Spain has shown that with such a&nbsp;combined MicroStep machine for thick sheet cutting it was possible to achieve time savings in production of up to 85%.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-style-default\"><img loading=\"lazy\" decoding=\"async\" width=\"1280\" height=\"960\" src=\"https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/G6xp6m-f102-52492.jpg\" alt=\"\" class=\"wp-image-5700\" style=\"aspect-ratio:16\/9;object-fit:cover\" srcset=\"https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/G6xp6m-f102-52492.jpg 1280w, https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/G6xp6m-f102-52492-300x225.jpg 300w, https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/G6xp6m-f102-52492-1024x768.jpg 1024w, https:\/\/www.pmsl.sk\/microstep\/wp-content\/uploads\/2024\/12\/G6xp6m-f102-52492-768x576.jpg 768w\" sizes=\"auto, (max-width: 1280px) 100vw, 1280px\" \/><figcaption class=\"wp-element-caption\">The leading Spanish machine manufacturer Solintal took advantage of MicroStep&#8217;s&nbsp;oxyfuel rotator and ABP in a&nbsp;big way: the needed steel parts of up to 160 mm thickness with complex bevels on non-linear contours that previously took 6 hours to produce are now ready in 45 minutes.<\/figcaption><\/figure>\n<\/div><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"featured_media":5694,"template":"","meta":{"_acf_changed":true},"product-shape":[27],"product-process":[67],"solution-layout":[167],"cutting-method":[22],"class_list":["post-5067","solutions","type-solutions","status-publish","has-post-thumbnail","hentry","product-shape-plate","product-process-3d-cutting","solution-layout-simple","cutting-method-oxyfuel"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.pmsl.sk\/microstep\/wp-json\/wp\/v2\/solutions\/5067","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.pmsl.sk\/microstep\/wp-json\/wp\/v2\/solutions"}],"about":[{"href":"https:\/\/www.pmsl.sk\/microstep\/wp-json\/wp\/v2\/types\/solutions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.pmsl.sk\/microstep\/wp-json\/wp\/v2\/media\/5694"}],"wp:attachment":[{"href":"https:\/\/www.pmsl.sk\/microstep\/wp-json\/wp\/v2\/media?parent=5067"}],"wp:term":[{"taxonomy":"product-shape","embeddable":true,"href":"https:\/\/www.pmsl.sk\/microstep\/wp-json\/wp\/v2\/product-shape?post=5067"},{"taxonomy":"product-process","embeddable":true,"href":"https:\/\/www.pmsl.sk\/microstep\/wp-json\/wp\/v2\/product-process?post=5067"},{"taxonomy":"solution-layout","embeddable":true,"href":"https:\/\/www.pmsl.sk\/microstep\/wp-json\/wp\/v2\/solution-layout?post=5067"},{"taxonomy":"cutting-method","embeddable":true,"href":"https:\/\/www.pmsl.sk\/microstep\/wp-json\/wp\/v2\/cutting-method?post=5067"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
