(1) Curve contours on the workpiece, straight lines, arcs, thread or spiral curves, especially non-circular curves and list curves given by mathematical expressions.
(2) The spatial curve or surface of the mathematical model has been given.
(3) Although the shape is simple, but the size is various and the detection is difficult.
(4) Inner cavities and box interiors that are difficult to observe, control and detect when processed by ordinary machine tools.
(5) Holes or planes with strict size requirements.
(6) A simple surface or shape that can be processed in one clamping.
(7) General processing content that can effectively improve productivity and reduce labor intensity by using CNC milling processing.
The main processing objects suitable for CNC milling include the following categories: plane contour parts, variable bevel parts, spatial surface contour parts, holes and threads, etc.
