Gmetal CNC Turning Service

At Gmetal, we provide CNC Turning Services by imported turning tools and precision machining capabilities, as well as various computerized CNC turning centers that can be programmed according to your exact requirements! No matter how simple or complex the products are. Whether you need a prototype or a large number of CNC production turning, you can get it at a competitive cost.

In addition to our multi-axis and multi-surface milling machines and lathes, we also provide internal CNC lathe turning services. The benefits of using CNC lathes for custom metal parts include reduced delivery time, tight tolerances, and excellent material compatibility. Gmetal have in-house facilities, originality, and knowledge to provide you with the results you need.


The Advantages of CNC Turning

High Precision: CNC lathes are capable of high levels of precision and accuracy. The use of computer control enables precise tool movements and close tolerances, resulting in parts with consistent dimensions and excellent surface finish.

Versatility: CNC turning can machine a wide range of materials including metals, plastics and composites. It can accommodate a variety of different part sizes and shapes, making it suitable for manufacturing simple and complex components.

Cost Effective: Once a CNC program is developed, CNC turning becomes a cost effective option for mass production. Automating the process reduces labor costs and increases efficiency, resulting in lower production costs per part.

Fast Production: CNC lathes can operate at high speeds, allowing parts to be produced quickly. This makes it ideal for meeting tight production deadlines and large order quantities.

Complex geometries: CNC turning can machine complex part geometries, including threads, tapers, chamfers, and other complex features. The ability to program precise tool movements enables the creation of detailed and complex assemblies.

The Surface Finishes of GMP CNC Turning

Whether Metal Fasternings of Metal Stampings are often exposed to harsh environments, moisture, chemicals, and atmospheric conditions that can lead to corrosion and degradation. So Gmetal provides different kinds of surface treatments for Metal stamping and machining parts, and the following are the surface finishes that we have:

  • Plain
  • Zinc Plated
  •  Hot Dipped Galvanized
  •  Powder Coating
  • Copper Plated

Tolerance of GMP CNC Turning

Dimensional Tolerance: The dimensional tolerance refers to the allowable variation in the size and geometry of the machined part. Common dimensional tolerances in CNC turning can range from +/- 0.005 mm (0.0002 inches) to +/- 0.1 mm (0.004 inches) or even tighter, depending on the specific requirements of the part.

Positional Tolerance: Positional tolerance refers to the allowable deviation in the location of a feature or the alignment between multiple features on a part. It ensures that the relative positions of features are within the specified tolerance zone. Common positional tolerances in CNC turning can range from a few tenths of a millimeter to a few millimeters, depending on the feature size and the required positional accuracy.

Gmetalparts offers Turning Parts with tolerances for feature size:

  • Standard:+/- .005
  • Minimum:+/- .002

Gmetalparts offers Turning Parts with tolerances for hole diameter:

  • Standard: +/- .005
  • Minimum: +/- .001

CNC Bending

CNC bending involves the use of a CNC machine that controls the movement of a hydraulic or electric press brake to bend the metal accurately and consistently according to programmed specifications.

The Process of CNC Turning

  1. Design and Programming: A 2D or 3D model is created, specifying the dimensions, features, and tolerances of the part.
  2. Workpiece Setup: The workpiece, usually a cylindrical bar of metal or other material, is securely mounted in the CNC lathe. The workpiece is held in place by a chuck or collet, which allows it to rotate while maintaining stability during machining.
  3. Tool Selection and Setup: The appropriate cutting tools are selected based on the desired machining operations and the material being machined.
  4. Workpiece Positioning: The CNC machine is programmed to position the cutting tool relative to the workpiece.
  5. Material Removal: The cutting tool is then fed into the rotating workpiece, removing material and shaping the part according to the programmed instructions.
  6. Secondary Operations: Additional machining operations, such as drilling, threading, grooving, or parting off, may be performed using specialized tools and techniques.
  7. Coolant and Chip Control: Coolant, typically in the form of cutting fluid, is used to lubricate and cool the cutting tool and workpiece during machining.
  8. Quality Control: Throughout the CNC turning process, periodic checks and measurements are performed to ensure the part meets the required specifications and tolerances.
  9. Finishing and Deburring: After the turning process is complete, the finished part may undergo deburring or additional finishing operations to remove any sharp edges, burrs, or surface imperfections.
