The Next Level of Machining: Certified High-Precision CNC Milling
HKAA sets the standard for complex, high-tolerance CNC milling. From rapid prototypes to global production runs, we ensure Precision Without Compromise, Delivered Worldwide
What is CNC milling?
CNC milling is a process that uses computer numerical control (CNC) technology to cut and process workpieces through rotating tools. According to computer instructions, the CNC milling machine controls the tool to move along a predetermined path, removes excess material from the workpiece, and forms the desired shape and size.
Why choose CNC milling?
High precision: CNC milling can achieve extremely high processing accuracy and meet the stringent requirements for part size and shape.
High efficiency: With a high degree of automation, the processing efficiency is much higher than traditional manual processing.
Complex shapes: Various parts with complex shapes can be processed, including curved surfaces, inclined surfaces, etc.
Mass production: Suitable for mass production to ensure product consistency.
Wide range of materials: Can process a variety of materials such as metals and plastics.
CNC milling material options
CNC milling can process a wide range of materials, the most common ones are:
Metal materials: aluminum alloy, stainless steel, copper, titanium alloy, etc.
Engineering plastics: ABS, PC, POM, PEEK etc.
Composite materials: carbon fiber, glass fiber, etc.
Different types of CNC milling machines
Based on the number and configuration of axes, CNC milling machines can be divided into the following categories:
Three-axis milling machine: Three linear axes X, Y, and Z, suitable for processing flat parts.
Four-axis milling machine: Add a rotary axis on the basis of three axes, which can process inclined surfaces and partial curved surfaces.
Five-axis milling machine: With two rotary axes, it has the strongest processing capacity and can process various complex curved surfaces.
