CNC process

 

 

CNC Milling

CNC milling uses a rotary milling cutter to cut the workpiece. The tool can be moved along multiple axes to remove material and form complex geometries. Application scope of Shanghai Starway CNC machining: Suitable for machining planes, grooves, holes, surfaces and various complex shapes. Often used in the manufacture of molds, mechanical parts, etc.

CNC Turning

On a CNC lathe, the workpiece rotates along its axis while the tool moves in different directions to remove the material. Turning is mainly used to process cylindrical, conical and symmetrical parts.
Scope of application of Shanghai Starway CNC machining: Commonly used in the production of shaft, sleeve and various symmetrical shape components.

CNC Drilling

CNC drilling is the use of a drill bit to drill the workpiece accurately. The drill bit can be moved along the X and Y axes to achieve drilling at different depths and locations.
Shanghai Starway CNC machining scope: suitable for metal, plastic and other materials hole processing, widely used in electronics, automotive, machinery manufacturing and other industries.

CNC Grinding

The surface of the workpiece is carefully machined using grinding machines and abrasive tools to improve surface finish and dimensional accuracy.

Scope of application: Suitable for high-precision surface processing, especially for hard materials and precision parts.

CNC Laser Cutting

High-intensity laser beams are used for precise cutting of materials. The laser beam can be controlled very finely, enabling high speed and high precision cutting.

Scope of application: Suitable for cutting metal, plastic and other materials, widely used in sign making, furniture manufacturing and mechanical parts processing.

CNC Laser Engraving

A laser beam is used to etch the surface of a material, often for marking and decoration. Laser engraving can create detailed patterns and text.

Scope of application: Suitable for metal, plastic and other materials, widely used in product marking, personalized customization and art production.

FAQ

Q: What is the difference between CNC machining and traditional machining?

A:Compared to traditional machining, CNC machining is controlled by computer programs and can provide greater accuracy, consistency, safety, applicability and automation. It enables the efficient production of complex parts and components, and reduces manual operations and errors.

Q: What are the types of CNC machine tools?

A: Common CNC machine types include: CNC milling machine CNC lathe CNC drilling machine CNC grinding machine CNC laser cutting machine CNC water knife cutting machine

Q: What is the price of CNC machining customization?

A: Most of the prices of CNC custom processing are closely related to the materials that the product needs to be made of, what to do, the processing process to use those, the quantity of production and whether the surface needs to be treated to test these factors, in short, the price of CNC machining custom varies due to a variety of factors, you can contact us for details to get an accurate quote.

Q: Can you customize CNC machining samples?

A: Yes, CNC machining can usually start with a sample. There are several benefits to making one or more samples before production: 1, Verify the design: samples can help you check whether the design meets expectations and whether there are any adjustments that need to be made. 2, check the quality of processing: Through the sample, you can evaluate the precision and quality of CNC machining to ensure that the final product meets the requirements. 3, cost savings: Before mass production, making samples can help you find potential problems and avoid wasting materials and time in mass production. Sample making usually involves detailed communication with the manufacturer to ensure that they understand your design requirements and can process according to them.
