CNC Turning Design Guidelines
To ensure the best balance between manufacturing cost and high precision, we recommend following these design standards for your CNC-machined parts.
Maintaining adequate wall thickness is critical to prevent part deformation during machining.
Metals: Recommended minimum 0.8mm (0.030″).
Plastics: Recommended minimum 1.5mm (0.060″).
Optimization Tip: Thinner walls increase vibration and reduce machining accuracy.
CNC milling tools are round, meaning vertical internal corners will always have a radius.
Recommended Radius: At least 1/3 of the cavity depth.
Best Practice: Use a radius slightly larger than the standard tool size (e.g., if a 6mm tool is used, use a 3.2mm radius) to reduce tool stress.
Optimization Tip: Avoid sharp 90-degree internal corners as they require expensive EDM (Electrical Discharge Machining).
Deep pockets can lead to tool deflection and chip evacuation issues.
Limit: Depth should ideally be no more than 4x the cavity width.
Maximum: Up to 10x width if using specialized tooling (increases cost).
Deep pockets can lead to tool deflection and chip evacuation issues.
Limit: Depth should ideally be no more than 4x the cavity width.
Maximum: Up to 10x width if using specialized tooling (increases cost).
Our standard machining tolerance is ISO 2768-m (Medium).
Standard: ± 0.125mm (± 0.005″).
Precision: Up to ± 0.005mm (± 0.0002″) upon request for critical features.
Advice: Only specify tight tolerances for critical mating surfaces to minimize unnecessary costs.
Our advanced CNC centers can handle parts up to:
CNC Milling: 1500mm x 800mm x 500mm (59″ x 31″ x 19″)
CNC Turning: 500mm (Diameter) x 1000mm (Length)
Why Choose Our CNC Turning?
Concentricity Mastery: Our technical team ensures perfect alignment of multi-diameter features, critical for rotating assemblies.
Surface Finish Excellence: Achieving Ra 0.4μm to 0.8μm “as-turned” finishes, reducing the need for secondary grinding.
Material Expertise: Proficient in turning tough alloys like Titanium, Stainless Steel 316, and engineering plastics like PEEK.
DFM for Turning: We analyze your drawings to suggest cost-saving threading and grooving optimizations.
What is CNC Turning and How Does it Work?
CNC turning is a subtractive manufacturing process that rotates a material bar in a chuck while a cutting tool removes material to create cylindrical shapes. By optimizing G-code toolpaths, our advanced CNC lathes rapidly produce high-precision parts with superior concentricity.
To further improve consistency and production efficiency, our CNC turning lines are equipped with robotic arm automation for fast and stable loading and unloading. This automated workflow helps reduce manual handling, supports higher-volume production, and ensures more reliable part-to-part repeatability throughout the machining process.
Whether you require standard “as-turned” finishes or functional post-processing like Anodizing (Type II/III), we ensure every component is thoroughly inspected and boxed for immediate assembly upon arrival.
CNC Turned Parts
Shafts & Axles: High-concentricity drive shafts, motor rotors, and precision axles.
Bushings & Spacers: Custom metal and plastic bushings with superior surface finishes for wear resistance.
Fittings & Connectors: Threaded connectors, nozzles, and fluid fittings with leak-proof precision.
Bolts & Fasteners: Custom high-strength fasteners and specialized screws for aerospace and industrial use.
FAQs
A: Our CNC turning centers are equipped to handle a wide range of cylindrical components, from simple shafts to complex geometries. We feature multi-axis lathes (including Y-axis and sub-spindle capabilities) that allow for eccentric drilling, tapping, and milling in a single setup, ensuring high coaxiality and reduced handling.
A: We have extensive experience machining both metals and engineering plastics, including:
Metals: Aluminum (6061, 7075), Stainless Steel (303, 304, 316, 17-4 PH), Carbon Steel, Brass, Copper, and Titanium.
Plastics: PEEK, POM (Delrin), Nylon, and PTFE.
Specialty Alloys: Inconel and Cobalt-Chrome for high-temperature or medical applications.
A: Our equipment can accommodate diameters ranging from 2 mm to 350 mm. For high-precision requirements, we can maintain tolerances as tight as ±0.005 mm (0.0002"), depending on the material and part dimensions. We utilize calibrated micrometers and CMM (Coordinate Measuring Machines) to verify every critical dimension.
A: Yes, we provide a "one-stop" solution. Beyond the "as-machined" finish, we offer various post-processing treatments including:
Anodizing (Clear, Color, Hard coat)
Passivation and Electro-polishing
Plating (Zinc, Nickel, Chrome, Gold)
Heat Treatment and Black Oxide coating
A: For mass production, we implement a strict SPC (Statistical Process Control) workflow. This includes initial sample inspection (FAIR), hourly in-process checks by operators, and a final OQC (Outgoing Quality Control) based on AQL standards. Every shipment is accompanied by a Material Mill Certificate and a detailed Dimension Inspection Report.
