Quality, accurate machining of stainless steel, brass, plastic and aluminum parts Swiss Technologies of New England makes the parts you need from brass, aluminum, tellurium copper, cold rolled steel, 316 and 17-4 stainless, plastics, and even some nickel alloys, but the material we use most commonly is 303 stainless steel. We also offer a wide variety of shop services and materials for small jobs. Do not hesitate to contact us about the unique particulars of the special job you have. The parts you need, the size you want, the quantity that's right. Our vast range of CNC Swiss screw machines runs the gamut from short runs of 1-1000 parts to long runs of 10,000 or more, so we are more than prepared to deliver any quantity you should desire. From small diameter parts of .010" all the way to large diameter parts of 1.25", we are your convenient and complete source for high-volume custom machined parts.

How do our Swiss-type screw machines produce such quality CNC machining?

The Swiss-type screw machines we use are automatic lathes that feature a sliding headstock and guide bushing. The bar stock, most commonly 12-foot metal or plastic bars, are held and rotated by the sliding headstock. This is the part of the machine that holds and rotates the bar stock at speeds ranging from 1000 RPM all the way to 10,000 RPM. The RPM for each project is determined by the diameter and type of material used. The cutting tools we employ, made of brazed carbide turning tools, cut-off tools or insert tools, make precision movements in and out of the material while the headstock moves the material forward. Together, they create the required lengths and diameters of your parts with unsurpassed precision.

Why are our Swiss-type screw machines superior to conventional lathes??

A conventional lathe simply cannot produce the parts a Swiss-type screw machine of the kind used by Swiss Technologies of New England can. Here's why: In a Swiss-type screw machine, the headstock contains a component that clamps the material, called the collet. The material is then fed through a guide bushing, which in most cases is made of carbide. This bushing is custom-adjusted to each project: loose enough so that the material can slide smoothly through it, but tight enough to keep the material from flexing away from the cutting tool.

This guide bushing is what separates Swiss-Type screw machines from conventional lathes. It allows Swiss-type machines to maintain very tight tolerances in relation to part diameter-even over long lengths. We are talking about plus or minus .0001" kind of precision. To take an example, if you needed to turn a .100" diameter over a 3" length, a Swiss-type screw machine is truly your only option. The material would bend away from the cutting tool on a conventional lathe, but a Swiss-type screw machine handles this job with ease. That's why Swiss-type machines are vital to creating the kinds of parts required by the many complex jobs of today.
