A: Swiss CNC machining is a precision turning process where the workpiece is supported by a guide bushing close to the cutting tool, allowing for tight tolerances and long, slender parts.
A: Common materials include stainless steel, aluminum, titanium, brass, copper, and engineering plastics.
A: Typical tolerances up to ±0.01 mm, depending on part geometry and material.
A: Medical, aerospace, automotive, electronics, robotics, semiconductor, and precision instrumentation are primary users.
A: Swiss CNC uses a guide bushing for support, allowing precise machining of small-diameter, long parts with minimal deflection, unlike standard CNC turning.
A: Yes, Swiss CNC machines can handle multi-step, intricate, and high-precision features, including threads, grooves, and micro-holes.
A: Swiss CNC is suitable for single prototypes, small batches, and high-volume production runs, offering flexibility across volumes.
A: Options include polishing, anodizing, plating, passivation, PVD coating, black oxide, and bead blasting,etc.
A: We are very flexible with quantities. There is no strict MOQ – we can support single prototypes, small batches, and high-volume production. Our goal is to grow with our customers from the prototype stage to mass production.
A: Provide complete dimensions, tolerances, material specifications, surface finish requirements, and any special post-processing instructions.
5-Axis CNC Machining Services simplify complex part production by reducing setups, improving accuracy, and enabling efficient machining of difficult geometries.
