FAQ
Swiss Machining FAQ
What information should I provide for a Swiss machining quote?
Please send your 2D drawing and/or 3D CAD file together with the required material, quantity, tolerances, surface finish, and any critical inspection requirements. The more clearly these requirements are defined, the more accurately we can review the part before quoting.
What size parts can JeaSnn produce with Swiss machining?
Our Swiss turning capability supports parts up to Ø20 mm in diameter and 200 mm in length. Final machinability is reviewed based on the complete part geometry and drawing requirements.
What tolerances can you achieve on Swiss machined parts?
Our machining tolerance capability ranges from ±0.01 mm down to ±0.005 mm. Actual achievable tolerances depend on part geometry, material, dimensions, and the specific features being controlled.
Can you machine complex features in addition to turning?
Yes. Depending on the part design, Swiss machining can produce features such as threads, grooves, bores, cross holes, stepped diameters, and other detailed features. Send us the drawing so we can review the complete feature requirements.
Can you work with the material specified on my drawing?
JeaSnn supports 50+ engineering-grade metals and plastics. Material availability and suitability are confirmed based on the specified grade, part geometry, and machining requirements.
How do I know if my part is suitable for Swiss machining?
Send us your drawing or CAD file. We will review the part size, geometry, material, tolerances, critical features, and quantity to determine whether Swiss machining is an appropriate production method for your part.
