itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><p><strong>The versatile and efficient production machine with CNC control<\/strong><\/p>\n<p>The Series 4 CNC round bending machines have two linearly adjustable bending rolls in addition to the top and bottom rolls. This design ensures high-quality rounding with minimized bending end. In combination with our CNC control, this is the most flexible round bending concept on the market and allows a high variety of parts without tooling costs. These machines are used both in simple manufacturing environments and in complex networked production plants.<\/p>\n<p>The machines feature a robust electromechanical drive concept with asynchronous three-phase motors and frequency converters in all linear axes. The same concept is used for the rotary drive, where all rollers are additionally synchronized via a gear train. The machine body consists of a stable steel structure that absorbs the bending forces. The 4 rollers are made of highly tempered steel; the roller surface is hardened and ground. The top roller is firmly mounted on the drive side in the quick-change device, which enables the top roller to be replaced within a very short time. The folding bearing is pneumatically operated.<\/p>\n<p>The modern CNC control has a graphical programming interface that enables automatic program creation by means of technology tables. These tables are pre-filled by our process engineers using modern analysis concepts, so that the customer already has a basic set of technology data for his specific plates at the time of delivery. The design and manufacture is carried out in accordance with the current CE specifications.<\/p>\n<\/div><\/section>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":4590,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-4593","page","type-page","status-publish","hentry"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/lechner-net.de\/en\/wp-json\/wp\/v2\/pages\/4593","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lechner-net.de\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/lechner-net.de\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/lechner-net.de\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lechner-net.de\/en\/wp-json\/wp\/v2\/comments?post=4593"}],"version-history":[{"count":0,"href":"https:\/\/lechner-net.de\/en\/wp-json\/wp\/v2\/pages\/4593\/revisions"}],"up":[{"embeddable":true,"href":"https:\/\/lechner-net.de\/en\/wp-json\/wp\/v2\/pages\/4590"}],"wp:attachment":[{"href":"https:\/\/lechner-net.de\/en\/wp-json\/wp\/v2\/media?parent=4593"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
