What is CNC Machining?

From Digital CAD Model to Physical Part

• Automated Manufacturing: Computer Numerical Control (CNC) technology uses pre-programmed instructions to control machines.

• Subtractive Process: Precisely cuts away and removes excess material from a solid block of raw material to form the desired part.

• Digitally Driven: Directly transforms digital CAD models (e.g., STEP, IGES files) into high-precision physical components.

• Customized Production: Capable of producing highly customized, complex-shaped parts, whether for prototypes or large-scale production.

Key Advantages: Precision, Speed, and Versatility

• High Precision & Tolerances: Achieves extremely high dimensional accuracy and tight tolerance control, meeting the most demanding design requirements.

• Fast Turnaround: Shortens production cycles, accelerating prototype development and time-to-market.

• Wide Material Range: Can machine various metals and engineering plastics, offering great flexibility for product design.

• Complex Geometries: Capable of handling intricate internal structures and external contours that are challenging with traditional methods.

• Excellent Repeatability: Ensures consistency and stable quality for every part in batch production.

CNC Milling Services for Complex Geometries

• Multi-axis Machining: Uses a rotating multi-point cutting tool to remove material along X, Y, Z, and even more axes.

• Suitable For: Producing parts with complex 3D shapes, pockets, slots, flat surfaces, and various features.

• Extensive Applications: Provides high-precision milling solutions for everything from prototyping to mass production.

CNC Turning Services for Cylindrical Components

• Turning Principle: The workpiece spins at high speed while a stationary cutting tool moves along the workpiece's axis to remove material.

• Specialized In: Designed specifically for producing parts with circular or cylindrical features, such as shafts, pins, bushings, and connectors.

• Efficient & Precise: Offers fast and high-precision cylindrical machining capabilities.

Advanced 5-Axis CNC Machining for Ultimate Precision

• 5-Axis Machining: The tool or workpiece can move simultaneously along five axes, allowing multi-sided machining in a single setup.

• Manufacturing Complex Parts: Ideal for machining parts with free-form surfaces, complex angled features, and irregular geometries.

• Reduced Setups: Significantly reduces the need for multiple setups, improving machining efficiency and surface finish.

• Higher Accuracy: Eliminates cumulative errors, ensuring tighter tolerances and superior part quality.

Secondary Processing: Multi-faceted Surface Finish

Finish Services is a secondary process for improving a part's surface function, including appearance, corrosion resistance, wear resistance, and electrical conductivity. It includes: anodizing, sandblasting (bead blasting), brushing, polishing, electroplating, passivation, painting (powder coating), heat treatment, laser marking, and chemical plating.

While there are many options, not all are suitable for all materials. For example, anodizing is good for used aluminum alloys, while passivation is used for stainless steel.

The choice depends on the part's application, material, design requirements, cost, and specific appearance and performance requirements. Compatibility issues may exist between different surface treatments, so selection requires a case-by-case approach.
