Swiss Screw Machining

The Swiss Screw Machine originated in Switzerland and was initially developed to create collets for watch balance springs. Today, Swiss screw machines are used to produced micro precision custom components for the aerospace, medical/dental, automotive, electronic, mechanical, and military industries. Swiss machined parts include miniature screws, fittings, pins, shafts, connectors,contacts, bushings and more.

Swiss precision machining uses either a single spindle cam operated or CNC machine to produce sophisticated, tight toleranced components with a high surface finish. Many materials can be used in Swiss screw machining including brass, aluminum, nickel, bronze, copper, titanium, steel, and stainless steel. Many plastics, such as Delrin and Nylon can also be turned in Swiss screw machining. In production, bar stock is fed through the Swiss screw machine to be cut as it is moved. The movement and depth of the cuts are determined by the speed at which the material spins and the design/shape of the cams on the Swiss screw machine. The Swiss screw machine advantages are close tolerance components that can be made in large volumes, at extremely competitive pricing. 

Another type of Swiss screw machine is the ESCOMATIC machine. While utilizing the same concept of traditional Swiss screw machine, the ESCOMATIC machine's cutting tools spin while the coil stock material remains stationary during the machining process. The precision material advances only when the next high precision component is ready to be produced. Our Escomatics can produce a tight toleranced components with absolutely NO cutoff burr.
