CNC Machining Process
  • Drawings and CAD Data preparation
    First, it is necessary to ensure that detailed part drawings and CAD (Computer-Aided Design) data are available. This data will be directly used for programming and machining on the CNC machine.
  • Material Preparation
    Select suitable raw materials based on the drawing requirements and perform necessary pre-processing, such as cutting the material blocks to the appropriate size and removing burrs.
  • Programming
    Use CAM (Computer-Aided Manufacturing) software to read the CAD files and generate G-code (numerical control programming language). The G-code precisely describes the tool path, speed, feed rate, and other machining parameters.
  • Machine Power-on Inspection
    After powering on the CNC machine, it is necessary to perform a three-axis home return and check the lubrication of the guide rails, spindle hydraulic oil, etc., to ensure the machine is in good working condition.
  • Tool Presetting
    Before machining, tool presetting must be performed. The purpose of tool presetting is to determine the accurate position of the tool within the machine coordinate system, ensuring machining accuracy. Common tool presetting methods include using a tool setter and directly referencing the workpiece surface.
  • After Machining
    Cleaning and Deburring:
    After machining, the parts need to be cleaned to remove any cutting fluid, oil, and burrs from the surface.
     
  • Quality Inspection
    Use measuring instruments or measurement equipments to inspect the machined parts for dimensional accuracy, shape accuracy, and surface roughness, ensuring the part quality meets the design requirements. The measuring instruments we have in house are ZEISS CMM, 2D Projector, Micrometer, Height gauge, Calipers, Pin Gauge,Thread gauge, Roughness tester, Ring gauge, ID Groove Gage, Hardness instrument, etc.
  • Anti-corrosion Surface Treatment
    Perform anti-corrosion treatment on the qualified parts to prevent rusting during storage and transportation.
    Sandblasting, Bead blasting, Spray paint, Anodic Oxidation, Electro-plating, Electroless-plating, passivation, chemical conversation, electrolyte polishing,
  • Packaging and Shipment
    The qualified parts that have passed the quality inspection are packaged, and the corresponding quality certificates are included. Then, they are shipped out according to the customer's requirements via Fedex/ DHL/ UPS express, etc.

3 Axis,4 axis cnc milling services

In the realm of modern manufacturing, CNC (Computer Numerical Control) precision machining stands as a cornerstone of innovation and quality. This advanced manufacturing process leverages computer-controlled machines to produce components with exceptional accuracy, consistency, and complexity. From aerospace and automotive to medical and electronics, CNC precision machining has become indispensable for industries that demand the highest levels of performance and reliability. In this article, we delve into the defining characteristics of CNC precision machining products and explore why they are integral to today’s industrial landscape.

The Characteristics of CNC Precision Machining parts

CNC precision machining is a subtractive manufacturing process where the movement of factory tools and machinery is controlled by pre-programmed computer software. This process includes cutting, milling, turning, drilling, and grinding raw materials such as metal, plastic, or composites to create highly accurate and intricate parts. The precision and repeatability of CNC machines make them ideal for producing components with tight tolerances and complex geometries.

At Shangchen, our CNC machining factory is equipped with over 200 industry-leading Fanuc 3-axis and 4-axis CNC machines. These high-quality machines operate by processing 3D CAD data, allowing for the rapid production of machined parts and prototypes. This results in a high production rate and exceptional accuracy, using strong and durable materials suitable for testing.
Exceptional Accuracy
One of the most defining features of CNC precision machining is its ability to produce parts with extremely tight tolerances of +/0.01mm. This level of accuracy ensures that components fit perfectly into assemblies, function as intended, and meet stringent industry standards. Whether it’s a medical implant or an aerospace component, precision is non-negotiable.
Complex Geometries
CNC machines excel at creating intricate shapes and complex geometries that would be challenging or impossible to achieve with manual machining. From 3D contours and fine details to undercuts and thin walls, CNC precision machining unlocks new possibilities in design and functionality.
 
 
Superior Surface Finish
The advanced tooling and controlled movements of CNC machines result in smooth, high-quality surface finishes. This reduces the need for additional post-processing steps, such as polishing, grinding, anodising, electro plating, passivation, oxide etc, and ensures that parts are ready for immediate use or assembly.
 
Consistency and Repeatability
CNC precision machining ensures that every part produced is identical to the last. This repeatability is critical for mass production, where consistency is key to maintaining quality and reducing waste. Once a design is programmed, the CNC machine can replicate it flawlessly, batch after batch.
 
Material Versatility
Shangchen is able to cnc manufacture with a great many different materials including; plastics ( ABS, PC, PMMA (Acrylic), PA (Nylon), PA+GF, PP, PE, PU, PS, POM, PVC, Bakelite, Chemical, Solid Wood.), metals (Copper, Aluminium,steel,brass,magnesium,Iron,zinc alloy etc) wood and other specialist materials.
 
High Strength and Durability
CNC precision machining produces parts with excellent structural integrity, making them highly durable and capable of withstanding extreme conditions. This is particularly important for components used in industries like aerospace, automotive, and energy, where reliability is paramount.
