CNC Turning Services

What is CNC Turning? / /

To manufacture parts with cylindrical features, CNC turning is used. During the CNC turning process, the raw material is rotated at a high speed as a single point cutting tool subtracts material. CNC turning is common for both metals and plastics. The advantages of CNC turning include high levels of accuracy, repeatability, speed and cost.

Differences Between CNC Turning and Milling / /

There are multiple differences between CNC turning and CNC milling. During CNC turning, the workpiece rotates while a cutting tool subtracts material. CNC milling uses a different approach, moving the tool along a stationary workpiece. CNC turning is good for projects that need cylindrical part, whereas CNC milling should be used for projects where cylindrical features are not required. CNC milling may be used as a secondary finish to add definition. Complex parts that require prismatic and cylindrical features may use a combination of milling and turning.

CNC Turning Specifications and Tolerances / /

Below are the specs and tolerances specific to CNC turning:

• Metal materials +/- 0.005
• Plastic materials +/- 0.008
• Pre-merger CNC machinery chart:

There are multiple important factors to consider when designing for a CNC turning project. The part’s desired geometry can affect how it will be positioned inside the CNC machine in addition to set up time. If the part must be manually repositioned, the accuracy and cost of a project can increase. Loose tolerances are possible as the tool used to cut can vibrate during operation. The workpiece may also vibrate due to temperatures and cutting forces, which may result in deformation. The shape of the part is also affected by the geometry of the tool used. Lastly, if the tool cannot reach a surface, it cannot be machined, making it impossible to create hidden internal geometries.

CNC Turning Finishes Available / /

• Bead Blasting: Bead blasting adds a satin or matte finish to a CNC part. The matte finish is accomplished by using a pressurized air gun to shoot glass beads at a part.
• Powder Coating: Following powder coating, the part has a thin protective layer that adds strength and wear-resistance. During the powder coating process, the part is first primed using a chromating or phosphating coat. Next, the part receives a dry powder coating from an electrostatic spray gun. Lastly, the part is cured in an oven.
• Anodizing: Once a CNC part has been anodized, it has an oxide layer that increases its density, thickness, and durability. Anodization also makes a part electrically non-conductive. During the anodizing process, the part is placed into an acid electrolyte bath which serves as an anode. A cathode is added to the part, and an electrical current is passed through the acid. Oxygen ions from the electrolyte and atoms from the alloy are combined along the surface of the part.
• As-Milled: As-milled or as-machined products do not require a secondary process. They will still have visible blemishes and may have a rough surface.
• Surface Grinding: Surface grinding produces a smooth finish. Surface grinding removes material by using a high-speed abrasive wheel as a cutting tool. The surface grinding process is used when a specific size or precision finish is required.
• Polishing: Polishing improves the dimensions and accuracy of a part while producing a mirror gloss finish. Polishing tools and abrasive materials are used to achieve a smooth surface.
• Passivate: After a CNC machined part has completed the passivation process, its corrosion resistance is improved. Passivation may include spray application, circulation in a chemical solution, gel application, or tank immersion.
• Chemfilm: Chemfilm finishing is a chemical conversion coat that adds corrosion resistance to aluminum substrates, acting as a base for organic coatings. The part is dipped, brushed, or sprayed with the chemfilm layer.
• Vacuum Metallization: The vacuum metallization process adds a mirror-like or decorative uniform finish while also improving thermal, air, light, or water barrier properties. In the vacuum metallization process, the part is placed inside a closed chamber where a metal vapor adheres and coats the part.
• Silkscreen: Screen printing is used to transfer a design or logo to a part. When a part is silk-screened, a mesh is used to apply ink onto the surface, but only to permeable areas that are not covered by a blocking stencil.
• Plating: Plating results in corrosion and abrasion resistance, conductivity, and reflectivity to parts. While electroplating, the part is submerged into an electrolyte bath with the material that will be used for the metal coating. An electrical charge causes the material to transfer to the part, resulting in a uniform metal coating.
• Tumbled: Tumbling or ultrasonic polishing removes any sharp points or edges from a machined part. During the tumbling process, the part is placed inside a barrel along with media, water, and detergent. The barrel tumbles at different speeds depending on the desired finish.
• Painting: Painting a part adds color, varnish, or ink. The painting process may include powder coating, liquid coating, or e-coating. Powder coating uses an electrostatically charged powder which produces a scratch-resistant and uniform coat on the metal part. When a part is liquid coated, wet paint is applied. The e-coating process involves dipping the part into a bath of paint where both the part and paint are electrified, causing the paint to adhere to the part.
