Swiss Screw Machining Services
Swiss screw machining is a high-precision manufacturing process that removes small amounts of material using cutting or milling tools. Unlike conventional machining equipment, Swiss screw machines use a special guide bushing that supports the workpiece very close to the cutting tool. This short distance greatly reduces deflection and vibration, allowing the tool to cut with much higher accuracy and produce finer surface finishes.
Common Materials for Swiss Screw Machining
Swiss screw machining handle a wide range of materials, including metals like brass, stainless steel, aluminum, titanium, copper alloys, and various exotic alloys, as well as plastics and other special materials. We offer Swiss machining capabilities across all these materials to deliver high-precision, small-diameter parts with tight tolerances and excellent surface finishes, no matter your industry or application needs.

FAQs
Why do we often get long, stringy chips that tangle and cause issues?
This is one of the top challenges in Swiss screw machining, especially with ductile materials (e.g., stainless steel, titanium, aluminum alloys). Long “bird’s nest” chips tangle around tools, workpieces, or spindles, leading to poor surface finish, dimensional variation, tool jams, or frequent machine stops for clearing. Swiss setups use high speeds, oil coolant, and an enclosed environment, which worsens chip evacuation compared to conventional turning.
Why do part dimensions vary or go out of tolerance during a production run?
Inconsistent part sizes (especially on long, thin, or small-diameter features) are very common. Key causes include: worn or improperly adjusted guide bushing, inconsistent or crooked bar stock diameter/straightness, thermal expansion from heat buildup, insufficient material support, or loose collet. Even s
What causes poor surface finish (chatter marks, roughness, or scratches)?
Rough or inconsistent finishes often result from vibration/chatter, dull or improperly selected tools, incorrect speeds/feeds, chip entanglement scratching the part, or guide bushing issues (e.g., too tight/loose clearance causing bar drag or marks). Heat and poor chip control in Swiss operations amplify these problems.
