CNC Milling FAQs

Zintilon has vertical CNC milling machines, horizontal CNC milling machines and multi-axis CNC milling machines. Vertical CNC mills are cost effective and have a wide range of applications. Horizontal CNC mills are used to cut grooves and slots in products and are ideal for cutting geared workpieces. Multi-axis CNC mills are CNC mills that can operate on more than four axes, allowing for the manufacture of more complex and precise parts.

CNC milling is suitable for machining parts with complex shapes, feature planes and irregular surfaces, such as grooves, gears, threads and special molded surfaces for dies and molds.

CNC milling machines are compatible with a wide range of materials, including metals, plastics and composites. Most commonly used are metals such as brass, titanium, aluminum or steel, and plastics such as PVC, ABS, polycarbonate and polypropylene.

3 Axis vs 4 Axis vs 5 Axis CNC Milling: Differences Contrast

Multi-axis milling, as the number of axes increases, the machining capacity is also enhanced accordingly, and more complex part designs can be processed. 5-axis CNC milling allows the largest machining range and flexibility, while 3-axis and 4-axis are relatively low.

3-axis CNC milling

  • Definition: The most basic CNC milling configuration with three linear moving axes (X, Y, Z axes).
  • Machining capabilities: Suitable for plane milling, grooves, bosses and other simple three-dimensional shapes.
  • Application range: Widely used in mold manufacturing, automobiles, aerospace and other industries.
  • Limitations: Complex bevel or curved surface machining is not easy because the tool axis is fixed.

4-axis CNC milling

  • Definition: A rotary axis is added to the 3-axis, usually the A axis (rotation around the X axis) or the B axis (rotation around the Y axis). Machining capabilities: Capable of more complex bevel machining, but still limited to a single rotary axis.
  • Application range: Suitable for machining parts with inclined surfaces or specific angle requirements.
  • Advantages: Improved machining flexibility and can reduce the re-clamping of workpieces.

5-axis CNC milling:

  • Definition: It has three linear moving axes (X, Y, Z axes) and two rotation axes (usually A axis and B axis or C axis).
  • Machining capabilities: It can perform complex three-dimensional surface machining, including inclined planes, curves and complex spatial surfaces.
  • Application range: It is very suitable for industries such as aerospace, medical equipment, and mold manufacturing, and is used to machine complex parts such as impellers, molds, etc.
  • Advantages: It provides extremely high machining flexibility and precision, and can complete the machining of the entire part in one clamping.
