FAQ
CNC Turning FAQs
What types of parts are best suited for CNC turning?
CNC turning is best suited for round or rotational parts such as shafts, bushings, sleeves, pins, spacers, fittings, connectors, and threaded components. It is also suitable for parts that require precise diameters, bores, grooves, shoulders, tapers, and internal or external threads.
What tolerances can CNC turning achieve?
CNC turning can achieve tight tolerances, but the achievable accuracy depends on the material, part size, geometry, and critical features. For reference, JeaSnn's CNC machining capability ranges from ±0.01 mm down to ±0.005 mm for suitable parts and features.
What materials can be used for CNC turning?
CNC turning supports a wide range of metals and engineering plastics. Common materials include aluminum, stainless steel, steel, brass, copper, bronze, titanium, POM, nylon, PTFE, and PEEK. Material selection usually depends on the required strength, corrosion resistance, weight, wear resistance, and application of the part.
What affects the cost of CNC turned parts?
The cost of CNC turned parts is mainly affected by material, part size, geometry, tolerances, quantity, surface finishing, and inspection requirements. Parts with complex features or very tight tolerances may require additional machining and inspection time, which can increase the manufacturing cost.
Is CNC turning suitable for prototypes and production runs?
Yes. CNC turning can be used for prototypes, small batches, and repeat production. Because the machining process is CNC-controlled, the same program and process can be used to maintain consistent dimensions and features across repeated production runs.
What information is needed to quote CNC turned parts?
An accurate CNC turning quote typically requires a 2D drawing or 3D CAD model, along with the material, quantity, tolerances, threads, surface finish, and inspection requirements where applicable. Providing complete specifications helps the manufacturer evaluate the machining requirements and quote the part more accurately.
