The Swiss Screw Machine was initially developed in the late 1800’s to create the high precision, subminiature watch parts at a rate faster than could be done manually. The quality of the watch was the direct result of the high precision that was built into it’s components. Today, Swiss screw machines use that high precision capability in much more diversified applications.  High precision Swiss screw machine components can be found in almost any industry –  aerospace, medical/dental, automotive, electronic and mechanical to name just a few.

Today, Swiss precision machining uses either the traditional single spindle cam operated or a CNC machine to produce sophisticated, tight tolerance 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, Peek and Nylon can also be turned on the  Swiss screw machine.

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. Exceptionally tight tolerances components made at a high speed are the advantages of Swiss screw machine, resulting in competitive pricing with outstanding quality.

The ESCOMATIC machine is a slight variation on the bar fed single spindle 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. The advantages?  Tight tolerance components, high speed production with absolutely NO cutoff burr.
