Cnc Milling: Alloy And Plastic

Cnc Milling is a common cold metal machining method. The difference from turning is that during milling, the tool rotates at high speed under the driving of the spindle, while the workpiece is relatively stationary.

Machining Process

The main machining objects suitable for CNC milling are the following categories: flat contour parts, chamfered parts, space curved contour parts, holes and threads.

  1. Curve contours on the workpiece, such as straight, circular arc, thread or spiral curves, especially non-circular and list curves given by mathematical expressions.
  2. The space curve or surface of the mathematical model has been given.
  3. Although the shape is simple, it has many sizes and is difficult to detect.
  4. The inner cavity and the inside of the box, which are difficult to observe, control and detect when processing with ordinary machine tools.
  5. Holes or planes with strict size requirements.
  6. Simple surfaces or shapes that can be machined in one setup.
  7. General machining content that can effectively increase productivity and reduce labor intensity by using CNC milling.

CNC milling is one of our strengths at PTJ Prototype Shop near Dongguan, CN. We are a full service machine shop, and we have acquired the milling knowledge, tradition, and experience to accommodate all your CNC milling needs. As we like to say here on our shop floor, “If you can draw, we can make it”. If you have solid or surface CAD drawings, we have the capability of machining directly from your files. This can eliminate errors that sometimes occur when programming from paper drawings.
