What is CNC milling?

 

Milling is a metal cutting process widely used in the manufacturing industry, a common metal cold processing method, and turning is different in the milling processing tool under the spindle drive high-speed rotation, while the workpiece is relatively static. It achieves the desired shape, size and surface quality by using a rotating milling cutter to remove material from the workpiece. Milling is the most commonly used process in machining, with the advantages of high efficiency, precision, flexibility, etc., widely used in aviation, automotive, mold, machinery and other industries.

 

Milling machine tools are horizontal or vertical milling machines, there are also large gantry milling machines. These machine tools can be ordinary machine tools, can also be CNC machine tools. Cutting with a rotary milling cutter as a tool. Milling is generally carried out on a milling machine or boring machine, suitable for machining planes, grooves, various forming surfaces (such as splines, gears and threads) and special shape surfaces of the die.

Processing objects: plane (horizontal plane, vertical plane, inclined plane), groove (right Angle groove, keyway, V groove, dovetail groove, T groove, arc groove, spiral groove), forming surface, hole (drilling, reaming, reaming, milling) and indexing work.

The difference between turning and milling:

Turning is used to process rotary parts, the parts are clamped on the machine tool spindle through the three-grip chuck, and high-speed rotation, and then use the turning tool according to the bus bar of the rotary body to cut out the product shape. The lathe can also be used for inner hole, thread, bite, etc., the latter two are low-speed processing.
