Swiss screw machining services use specialized CNC equipment to produce turned parts with high-quality finishes that are comparable to ground finishes. They can also produce small-diameter parts with high-finish, close-tolerance, bearing surfaces. Swiss screw machines were originally developed to produce collets for watch balance springs. Today, they are used to manufacture mathematically precise parts for aerospace, defense, and electronics applications. Swiss screw machining services can also produce miniature screws, grommets and bobbins, contact pins for electronics components, and fasteners used in surgical and medical applications. Material capabilities for Swiss screw machining services include aluminum, brass, bronze, copper, nickel, nickel alloys, plastics, precious metals, steel, stainless steel, steel alloys, and titanium.
Swiss screw machining services may provide additional services such as CAD/CAM support, design assistance, just-in-time (JIT) delivery, rapid prototyping, low-volume production, and high-volume production. Computer aided design or drafting (CAD) is used to design parts quickly and accurately. Computer aided manufacturing (CAM) is used to fabricate products directly from CAD outputs. Swiss screw machining services that provide design assistance can help customers with concepts, manufacturing costs, manufacturing techniques and material considerations such as sourcing. They may also be able to assist with upgrading, redesigning, reevaluating or modernizing existing products to increase performance and/or reduce manufacturing costs. Some Swiss screw machining services have just-in-time (JIT) manufacturing capabilities or can provide prototypes for use in presentations or functional testing. Others provide low-volume or high-volume production.
Swiss screw machining services are located across the United States and around the world. They adhere to a variety of certifications, regulatory requirements, and quality standards. Swiss screw machining services follow four main specifications from the International Standards Organization (ISO): ISO 9001:2000, ISO 13485:2003, ISO 14001, and ISO/TS 16949:2002. AS 9000, AS 9100, and QS-9000 are industry-specific quality standards that are based on ISO 9001. Both AS 9000 and AS 9001 define quality management system (QMS) requirements for suppliers to the aerospace industry. QS-9000 is a quality standard for suppliers of DaimlerChrysler Corporation, Ford Motor Company, and General Motors Corporation. Some Swiss screw machining services are registered with the Food and Drug Administration (FDA), or comply with U.S. military specifications (MIL-SPEC). Others meet internal company specifications or requirements from original equipment manufacturers (OEM).
