Curve contour on workpiece, straight line, arc, thread or spiral curve, especially non-circular curve and list curve given by mathematical expression; space curve or curved surface of given mathematical model; parts with simple shape but various sizes and difficult detection; inner cavity and box which are difficult to observe, control and detect when processing with ordinary machine tool Internal, etc;
What Is The Main Processing Range Of CNC Milling
The main processing objects suitable for CNC milling are as follows: plane profile parts, variable angle parts, space surface profile parts, holes and threads, etc.
The main machining objects suitable for CNC milling are plane profile parts, variable angle parts, space surface profile parts, holes and threads.
Plane parts are characterized by the fact that the machined surface can be parallel to the horizontal plane, perpendicular to the horizontal plane, or at a fixed angle with the horizontal plane; most of the parts belong to plane parts, which are the simplest parts in CNC milling. Generally, they can be machined only by using the two-axis linkage or three-axis linkage of the three-axis CNC milling machine.
The feature of curved surface parts is that the machined surface is a space curved surface. In the process of machining, the machined surface and the milling cutter are always in point contact. Ball end milling cutter is often used for surface finishing. It is very important to optimize the cutting process by selecting special tool size, groove shape and brand combination, cutting parameters and appropriate milling strategy.
Rough machining process: round blade milling cutter, ball end milling cutter and end milling cutter with large tip arc radius.
Semi finishing process: round blade milling cutter (diameter range of 10-25 mm round blade milling cutter), ball end milling cutter.
Finishing process: round blade milling cutter, ball end milling cutter.
Residual milling process: round blade milling cutter, ball end milling cutter, vertical milling cutter.
Milling is usually carried out on milling machine or boring machine, which is suitable for machining plane, groove, various forming surfaces (such as spline, gear and thread) and special surface of die.

Plane parts
The characteristics of plane parts are that the surface can be parallel to the horizontal plane, or perpendicular to the horizontal plane, or at a fixed angle with the horizontal plane; most of the parts processed on the CNC milling machine belong to plane parts, and plane parts are the simplest parts in the CNC milling process, which generally only need the two-axis linkage or three-axis linkage of the three-axis CNC milling machine It can be processed. In the process of machining, the machining surface is in contact with the cutter, and the end milling cutter or nose cutter can be used for both rough and finish machining.
Surface parts
The feature of curved surface parts is that the machined surface is a space curved surface. In the process of machining, the machined surface and the milling cutter are always in point contact. Ball end milling cutter is often used for surface finishing
