National Technologies provides a full line of CNC turning capacity. An extensive complement of Hardinge & Haas super-precision CNC turning centers employing the latest technologies, provides the precision advantage National Technologies brings to its CNC turning customers. Close tolerances, tight concentricities, fine finishes and complex features are all part of National Technologies CNC turning expertise. The best in CNC equipment, engineering and experience make National Technologies the performance leader in CNC turning.
Our CNC milling is an extensive part of the machining capabilities that National Technologies provides to its customers. With CNC milling made possible via our vertical machining centers with capacity ranging from small drill-tap VMCs, to large multi-axis auto load equipment, and in-house fixture design, National Technologies engineers and produces the most effective CNC milling processes to provide cost effective solutions for long and short run production lots. With in-house tool design, quick turn-around capabilities and the expertise to provide maximum reliability; National Technologies can take your CNC milling opportunities and get results that work for you.
National Technologies has been a leader in the screw machining industry since 1959. Our capabilities in high-volume, multiple-spindle screw machining, as well as lower volume single-spindle production, combined with six-spindle chucker machining and a full array of secondary operations, make National Technologies the performance leader in screw machining and production parts. National Technologies’ extensive screw machining experience with varied materials, finishes, tolerances and complex features provides solutions and quick-turn-around for even the toughest screw machining projects. If screw machining is what you want, National Technologies is the quality, price and delivery source you need.
National Technologies provides a full array of Value Added Services and finish machining capabilities. These services complement our core capabilities and provide a “one-stop shop” where our customers can get a complete part and save themselves the hassle of managing numerous operations. Our supply chain management team oversees all aspects of production to ensure the job is done according to the customer’s specifications and expectations.
We guarantee quality. Our disciplined approach ensures a consistently good product.
For each machining sequence, operators complete a formal start-up report, ensuring that they understand their part of the process - and subsequent processing relevant to their operation. This report improves material flow and eliminates the potential for operator error.
Identification documents are attached to all lots ensuring complete traceability.
Each part is sampled by ASQ-certified inspectors. If the part doesn't pass our AQL criteria (C=0 1.0 AQL), it doesn't leave the dock. Period.
Your order begins at a pre-production engineering meeting. Nothing at National Technologies is done "on the fly." Our engineers review your prints and decide upon the most efficient process for production.
Next, our engineering department issues process documents that highlight details important to each machinist. These drawings clarify specifications, secure conversions, and highlight critical dimensions. This extra step eliminates any potential for operator error as the part moves through production.
Plus, our pre-engineering protects the integrity of each part's critical dimensions in a second way - by anticipating distortions and preventing them. Processes, such as heat treating or plating, may affect material ...
