Simply place the arch gauge on the surface of the object to be measured and the radius of curvature immediately appears on the display. <\/p>\n\n<p class=\"wp-block-paragraph\"><strong>Accurate bend measurement<\/strong> is essential on any tube or profile bending machine. Investing in a reliable arc gauge can help you get the most out of the bending operation, ensuring that all bends are precise and comply with the required specifications. Arc gauges measure the arc length from one end of the bend to the other, enabling extremely precise measurements compared with manual methods.  <\/p>\n\n<!--more-->\n\n<div style=\"height:40px\"

<strong>objects with curved geometry such as tubes, sheet metal, glass and profiles. <\/strong>Their technology makes it possible to calculate the curvature of such materials with extreme precision. <\/p>\n\n<p class=\"wp-block-paragraph\">Using these instruments, professionals and enthusiasts in fields such as <strong>mechanical engineering, steelwork, joinery, glass production and furnishing elements<\/strong> can create objects and parts with perfectly calibrated, uniform curves, guaranteeing a high-quality end result.<\/p>\n\n<p class=\"wp-block-paragraph\">Arch gauges make it possible to determine the precise curvature of every single tube or profile, <strong>avoiding problems during positioning and installation.<\/strong><\/p>\n\n<p class=\"wp-block-paragraph\">Sheet metal and glass also require particular curvature, especially in architecture and in the furniture industry. <\/p>\n\n<p class=\"wp-block-paragraph\">Arch gauges allow curvature to be measured precisely and uniformly, avoiding the risk of chipping or breaking the material during processing and positioning. <\/p>\n\n<p class=\"wp-block-paragraph\">These instruments also make it possible to <strong>calibrate the curvature of sheet metal and glass perfectly<\/strong>, guaranteeing an end result that is both attractive and functional.<\/p>\n\n<p class=\"wp-block-paragraph\">Lastly, arch gauges are widely used <strong>in the metalworking industry for bending metal profiles<\/strong>. They allow the most accurate possible measurement, avoiding errors that could compromise the stability and functionality of the products made.  <\/p>\n\n<p class=\"wp-block-paragraph\">What is more, the measurements taken with arch gauges make it possible to guarantee <strong>uniform curvature throughout production<\/strong>, assuring customers of an excellent end result.<\/p>\n\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n<div class=\"schema-faq wp-block-yoast-faq-block\"><div class=\"schema-faq-section\" id=\"faq-question-1783344515424\"><strong class=\"schema-faq-question\">How is bending checked on tube and profile bending machines?<\/strong> <p class=\"schema-faq-answer\">With a DIACHECK-CT digital arc gauge: placed on the part, it measures the radius of curvature using the three-point circle method and shows the value on the display, verifying that the bend complies.<\/p> <\/div><div class=\"schema-faq-section\" id=\"faq-question-1783344515425\"><strong class=\"schema-faq-question\">What is the measuring range?<\/strong> <p class=\"schema-faq-answer\">From 100 to 10000 mm, for internal and external radii and diameters.<\/p> <\/div><div class=\"schema-faq-section\" id=\"faq-question-1783344515426\"><strong class=\"schema-faq-question\">Why is it more precise than manual methods?<\/strong> <p class=\"schema-faq-answer\">The arc gauge measures the arc between the contact points directly, eliminating the approximations of templates and manual comparisons.<\/p> <\/div><div class=\"schema-faq-section\" id=\"faq-question-1783344515427\"><strong class=\"schema-faq-question\">Can it be connected to a PC or PLC?<\/strong> <p class=\"schema-faq-answer\">Yes: via Bluetooth connection the instrument can transmit the measurement to a PC or PLC for recording and process control.<\/p> <\/div><div class=\"schema-faq-section\" id=\"faq-question-1783344515428\"><strong class=\"schema-faq-question\">Is it suitable for use on the production line?<\/strong> <p class=\"schema-faq-answer\">Yes: it is portable, robust and protected by a case, with an interchangeable arc attachment to suit small, medium and large radii.<\/p> <\/div><\/div>\n\n<div style=\"height:50px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h4 class=\"wp-block-heading has-ti-accent-color has-text-color has-link-color wp-elements-2\">Contacts &amp; Information<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Contact for general information : <a href=\"mailto:info@roder.it\">info@roder.it<\/a><br\/><br\/>Machine Vision Division of RODER : <a href=\"http:\/\/www.rodervision.com\">www.rodervision.com<\/a><br\/>RODER Instruments Division : <a href=\"http:\/\/www.rodervision.com\">www.innovacheck.com<\/a><br\/>More about RODER : <a href=\"https:\/\/roder.it\/en\/contacts\/\">about us<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The information contained in this website is provided for information purposes only.
