What Is CNC Turning
CNC Turning, also known as Computer Numerical Control Turning, is a manufacturing process that involves securing bars of material within a chuck and rotating them while a tool is progressively fed towards the material to remove excess material, thus shaping it into the desired form. A central turret, as depicted in the center, carries tooling attachments and is programmed to move towards the raw material bar, selectively removing material to achieve the programmed outcome. This process is often referred to as "subtraction machining" because it centers on material removal. In cases where the machining center possesses both turning and milling capabilities, like the one described above, the rotation can be halted to facilitate milling operations for creating different shapes.

Surface Finishes for CNC Turning
We offers a diverse range of surface finishes to enhance the quality of your CNC turned parts. These finishes are applied with the objective of improving appearance, surface hardness, roughness, chemical and corrosion resistance, among other benefits. Additionally, they help conceal any visible tool marks resulting from areas cut with live tooling. Here are some of our top choices for surface finishes:
Grinding: Grinding using abrasive tools can achieve a very smooth surface, eliminating any traces and irregularities that may have been left during the cutting process.
Polishing: Polishing involves the use of polishing agents and tools to enhance the surface gloss and smoothness, making it more even and reflective.
Sandblasting: Sandblasting is the process of spraying fine particles onto the surface of the part to remove roughness and create a uniform matte effect.
Electropolishing: This method improves surface smoothness and uniformity by treating the part in an electrolyte solution.
Chemical Etching: Chemical etching involves using specific chemical liquids to etch the surface of the part, allowing for the processing of details, patterns, and improving surface quality.
Laser Marking: Laser marking uses a laser beam to engrave patterns, text, or markings on the part's surface, achieving high-precision marking and decorative effects.
Hardening: Hardening involves heat or chemical treatment of the part's surface to enhance hardness and wear resistance.
Coating: Coating involves applying a layer of special material, such as chrome plating, nickel plating, zinc plating, etc., to provide additional protection and improve the part's corrosion resistance.
Anodizing: An electrochemical treatment that forms a protective and corrosion-resistant oxide layer on the surface.
Our High Standards For CNC Turning
We prioritize the production of your custom parts in strict compliance with rigorous manufacturing standards, ensuring adherence to the strict standard. To ensure quality, we conduct thorough verification of these requirements and include an inspection report with each order we ship.
Following the completion of the turning process, the parts can be left in their turned state or undergo post-processing as specified in the customer's requirements outlined in the purchase order (PO). This post-processing aims to enhance surface properties and achieve a visually appealing cosmetic appearance.
Our in-house quality checks are conducted before the Manufacturing Partner (MP) sends the custom parts to our facilities or their final destinations. These checks guarantee that every part adheres to the specifications outlined in the order and meets the high standards set by Lingshantech. Any requested documentation is also completed at this stage, ensuring the conformity of the parts before they are shipped out.
ThesunIndustry upholds a 100% commitment to quality according to ISO9001 and IATF 16949 standards. We maintain strict quality control throughout every step of the production process, from incoming quality inspection of materials to outgoing quality inspection.
We take great pride in our dedication to rigorous quality control and providing exceptional customer service. Our goal is to exceed customer expectations in all aspects of the product manufacturing process, recognizing the significant responsibility we have towards our customers.
