What is CNC Machining?
CNC machining is a kind of automatic manufacturing technology which controls the machine tool movement through computer program and realizes the operation of cutting, drilling, milling and turning of various materials.
The main types of CNC machining are: CNC milling, CNC turning, CNC drilling, CNC grinding, CNC laser cutting, CNC EDM and other processing methods.
This technology is generally mainly used in the medical industry, electronics industry, mold manufacturing, automotive industry
What are advantages of cnc machining?
High precision, good consistency
One of the most significant advantages of CNC machining in our factory compared to manual machining is precision. Without the constant attention of a skilled operator, once programmed, CNC machines are able to maintain a high degree of consistent part quality in mass production.
Efficiency and productivity
One of the advantages of CNC machining at Starway Shanghai is that it is faster. In the use of CNC machine tools, because CNC machine tools can be mass-produced 24 hours without fatigue, the operator can be more efficient
Flexibility and adaptability
The CNC machining in Shanghai Starway factory can complete any mechanical part you can think of, just be able to give the product drawings, they are different from the traditional machine production process, because the CNC machine can be programmed to adapt to different design requirements or production tasks, so its products are very adaptable
More detailed processing
The CNC machining at the Shanghai Starway plant can achieve very fine tolerances and is suitable for high-precision engineering requirements. It can also be machined to a smooth surface, reducing the need for subsequent finishing.
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.
CNC applies to materials and surface treatment processes
CNC material type
CNC machine can be compatible with a variety of materials, including but not limited to: aluminum alloy, steel alloy, copper alloy, zinc alloy, silver, PVC, PP, PE and other materials processing custom
CNC surface treatment process
Common surface treatment methods include: sandblasting, polishing, electroplating, oxidation treatment, spraying, anodizing, heat treatment, electroless plating, passivation treatment, laser etching and other methods to operate
