What Are The Uses Of CNC Milling Machine
May 28, 2018

A CNC milling machine is a machine tool with a wide range of applications. It is mainly used for the machining of various complex plane, curved and shell parts. For example, milling of various types of cams, dies, connecting rods, blades, propellers, and boxes etc. Processing, but also for drilling, expansion, Germany, hinge, tapping, punching and other processing · for machining cabinets, cavities, molds and other parts, the same specifications of the CNC milling machine and machining center can meet the basic processing requirements, However, the prices of the two kinds of machine tools are far apart. Therefore, in the processing of the above-mentioned parts, only the processes that need to change the tools very frequently select the machining center, and if a tool is fixed for milling for a long time, the plane can be machined on the milling machine (horizontal plane). , vertical surface), grooves (keyways, T-slots, dovetails, etc.), toothed parts (gears, spline shafts, sprockets, spiral surfaces (threads, spiral grooves), and various surfaces. In addition, It can be used for the surface, internal hole machining and cutting work of the rotary body, etc. When the milling machine is working, the workpiece is mounted on the workbench or the attachments such as the dividing head and the milling cutter rotates as the main motion. With the feed motion of the table or milling head, the workpiece can obtain the required machining surface.Because of multi-knife interrupted cutting, the productivity of the milling machine is high.

The use of CNC milling machine. CNC milling machine main processing objects are the following.

(1) Plane Parts

The parts whose angle is perpendicular to the horizontal plane or the processing plane and the horizontal plane of the numerical control processing surface are called plane parts. Its feature is that the faces of each machining unit are parallel planes or can be expanded into planes. Most of the parts that are processed by CNC milling machines belong to flat-type parts.

(2) Surface Parts

Surfaces with curved surfaces are called surface parts, also known as stereotypes · their features are that the dry surface cannot be expanded into a flat surface, and the processing surface is always in contact with the milling tool point. The CNC milling machine that processes curved surface parts generally uses three. Coordinated CNC milling machine.

(3) Beveled parts

The included angle between the processing surface and the horizontal plane is continuously changed, and the zero flare angle is zero. There are many such parts. For the aircraft parts, the processing plane cannot be unrolled to the plane · however, it is a straight line at the moment when the machining surface is in contact with the circumference of the milling cutter. It is best to use the four-CNC milling machine coordinate system or the five-axis CNC milling machine for machining the good parts. If there is no such machine, you can use the three-axis CNC milling machine to process the two-axis half-coordinates.
