Unlike older cam-operated lathes, these machines allow programming of complex geometries, tolerance control in the micron range, and consistent repeatability part after part, even in <a href=\"https:\/\/estampacionenfrio.com\/en\/blog\/what-does-mass-production-of-metal-parts-consist-of\/\">medium and long production runs.<\/a> <\/p>\n\n<p class=\"wp-block-paragraph\">Not all CNC lathes are the same. The headstock architecture, bed rigidity, number of axes, and control system determine what type of part can be reliably manufactured. That is why at Estampaciones Lemec we work with two world-leading platforms: <strong>Star Micronics<\/strong> and <strong><a href=\"https:\/\/es.dmgmori.com\/\">DMG MORI.<\/a><\/strong>  <\/p>\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"654\" height=\"436\" src=\"https:\/\/estampacionenfrio.com\/wp-content\/uploads\/2026\/06\/equipos-decoletaje-cnc-star-micronics-dmg-mori.jpg\" alt=\"\" class=\"wp-image-2653\" srcset=\"https:\/\/estampacionenfrio.com\/wp-content\/uploads\/2026\/06\/equipos-decoletaje-cnc-star-micronics-dmg-mori.jpg 654w, https:\/\/estampacionenfrio.com\/wp-content\/uploads\/2026\/06\/equipos-decoletaje-cnc-star-micronics-dmg-mori-300x200.jpg 300w\" sizes=\"auto, (max-width: 654px) 100vw, 654px\" \/><\/figure>\n<\/div>\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h2 id=\"tornos-cnc-de-cabezal-movil-star-micronics\" class=\"wp-block-heading\">Sliding Headstock CNC Lathes: Star Micronics<br\/><\/h2>\n\n<p class=\"wp-block-paragraph\"><strong>Sliding headstock CNC lathes<\/strong>, also known as <em>Swiss-type<\/em> lathes, are the benchmark for slender, small-diameter parts requiring <strong>extreme-precision screw machining.<\/strong><\/p>\n\n<h4 id=\"como-trabajan-en-nuestra-planta\" class=\"wp-block-heading\"><strong>How They Work in Our Plant<\/strong><\/h4>\n\n<p class=\"wp-block-paragraph\">At Estampaciones Lemec, we use STAR machines with the following capabilities:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Meehanite cast iron bed <\/strong>that absorbs vibrations and maintains dimensional stability during extended cycles.<\/li>\n\n\n\n<li><strong>Dovetail guides<\/strong> on the tool post, ideal for demanding cuts in stainless steels and tough materials.<br\/><br\/><\/li>\n\n\n\n<li><strong>Step Cycle Pro<\/strong> system for chip breaking through synchronized vibration, enabling unattended 24\/7 production without stops due to chip buildup.<br\/><br\/><\/li>\n\n\n\n<li>Ability to work with multiple tools simultaneously, reducing cycle times.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">These are the machines we use to manufacture special screws, bushings, connectors, and small-diameter parts where material deflection would compromise quality on a conventional lathe.<\/p>\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h2 id=\"tornos-cnc-de-cabezal-fijo-dmg-mori\" class=\"wp-block-heading\">Fixed Headstock CNC Lathes: DMG MORI<\/h2>\n\n<p class=\"wp-block-paragraph\"><strong>Fixed headstock CNC lathes<\/strong> are the solution for larger-diameter parts, robust geometries, and combined turning and milling operations in a single setup.<\/p>\n\n<h4 id=\"que-aportan-a-nuestra-produccion\" class=\"wp-block-heading\"><strong>What They Bring to Our Production<\/strong><\/h4>\n\n<p class=\"wp-block-paragraph\">In our plant, DMG MORI machines allow us to:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><strong>Complete machining in a single setup<\/strong>, eliminating secondary operations and reducing errors from repositioning.<\/li>\n\n\n\n<li><strong>MASTER family spindles <\/strong>with a 36-month warranty with no hour limit, ensuring stability and production continuity.<\/li>\n\n\n\n<li><strong>CELOS digital management system<\/strong>, which optimizes setup times and enables full traceability of every batch.<\/li>\n\n\n\n<li><strong>Capacity up to 92 mm diameter <\/strong>with automatic bar feeders, covering a wide range of series-produced parts.<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">The combination of DMG MORI fixed headstock with Star Micronics sliding headstock gives us a versatility that few screw machining workshops in Spain can offer.<\/p>\n\n<div style=\"height:30px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n<h2 id=\"tornos-automaticos-de-decoletaje-por-que-importa-tener-ambas-arquitecturas\" class=\"wp-block-heading\">Automatic Screw Machining Lathes: Why Having Both Architectures Matters<\/h2>\n\n<p class=\"wp-block-paragraph\">Many suppliers work with only one technology.
