CNC turning milling parts OEM

Compared with the machining center, the CNC milling machine in addition to the lack of an automatic tool change function and tool library, other aspects are similar to the processing center, can also drill, expand, hinge, trance and file hole processing and tapping, but it is mainly used for the workpiece milling processing, here the main processing objects and classification is also from the perspective of milling processing to consider.

(1) Plane parts

The parts whose processing surface is parallel, perpendicular to the horizontal plane, or the Angle between the processing surface and the horizontal plane are called plane parts.

At present, the vast majority of the parts processed in CNC milling machines belong to plane parts. The feature of planar parts is that the surface of each processing unit is a plane or can be expanded into a plane. For example, the curve contour surface M and the correct table surface N in the figure are all planes after expansion.

Plane parts are the most simple type of CNC milling objects. Generally, they can be processed by using the two-coordinate linkage of a 3 coordinate CNC milling machine.

(2) variable bevel parts

The Angle between the processing surface and the horizontal surface is continuously changed parts called variable Angle parts. Most of these parts are aircraft parts, such as the overall beam, frame, edge, and ribs on the aircraft, in addition to the inspection fixture and assembly frame. The variable bevel machining surface of the variable bevel parts can not be expanded into a plane, but in the processing, the machining surface and the milling cutter circumference contact moment is a straight lines. It is best to use 4-coordinate and 5-coordinate CNC milling machine swing Angle processing, in the absence of the above machine, can also be used on the 3-coordinate CNC milling machine for 2. 5 coordinate approximate processing.

(3) Surface class (three-dimensional class) parts

Machining surface for space surface parts called surface parts.

One of the features of the parts is that the processing surface can not be expanded into a plane; The second is the machining surface and the milling cutter is always in point contact. These kinds of parts generally use a 3 coordinate CNC milling machine.
