Advantages of CNC Turning
SelenPreci provides custom CNC turning services for precision shafts, bushings, fittings, and other rotational parts. We support prototype and production orders with consistent quality and machining accuracy. Key advantages of our CNC turning services include:
Efficiency in Producing Symmetrical Parts
CNC turning produces cylindrical parts such as shafts, pins, and bushings. The workpiece rotates while cutting tools shape it, making the process efficient for consistent, high-volume production.
Cost-Effectiveness for Large Batches
CNC turning reduces labor and production costs through automated machining and continuous cutting. It is well suited for cost-effective, high-volume production of consistent parts.
Precision and Consistent Quality
CNC turning delivers consistent dimensional accuracy for precision parts. Tolerances can reach ±0.005 mm, depending on part design and requirements.
Superior Surface Finish
CNC turning produces smooth surface finishes that can reduce the need for secondary processing. Surface quality can be tailored to the requirements of each part.
Versatility in Materials
SelenPreci offers CNC turning in metals such as aluminum, stainless steel, brass, and titanium, as well as engineering plastics including POM, PTFE, and Nylon. Material selection is based on your part's application and performance requirements.
Reduction in Setup Time and Tool Changes
CNC turning can combine operations such as turning, drilling, and threading in one machining cycle, reducing setup time and improving production efficiency.
Precision Inspection for CNC Turned Parts
We inspect critical diameters, concentricity, and surface finish to verify CNC turned parts against drawing specifications.
▪ Diameter measurement
▪ Concentricity inspection
▪ Surface finish verification
