Cnc Milling Service

What is CNC milling?

CNC milling refers to the use of a rotating multi-blade tool to cut a workpiece and is a highly efficient machining method. When working, the tool rotates (main motion), the workpiece moves (for feed motion), and the workpiece can also be fixed, but at this time, the rotating tool must also move (complete the main motion and feed motion at the same time). Milling machines include horizontal milling machines or vertical milling machines, as well as large gantry milling machines. These machine tools can be ordinary machine tools or CNC machine tools. Cutting with a rotating milling cutter as a tool. Milling is generally carried out on a milling machine or a boring machine, and is suitable for processing planes, grooves, various forming surfaces (such as splines, gears and threads) and special shapes of molds.

What can CNC milling produce?

CNC milling usually includes the following main types of machining parts:

1. Box and shell parts, referred to as: box and shell.

2. Fork and bracket parts, referred to as fork bracket.

3. Shaft parts, such as spline shafts (spline milling machines). And the keyway on the shaft, the backstop washer groove, etc. (keyway milling machine).

What are the advantages of CNC milling?

1. It is processed by multi-blade tools, the blades are alternately cut, the tool cooling effect is good, and the durability is high.

2. Milling has high production efficiency and wide processing range. Various milling cutters can be used on ordinary milling machines to complete the processing of planes (parallel surfaces, vertical surfaces, inclined surfaces), steps, grooves (right-angle grooves, V-shaped grooves, Processing tasks such as T-shaped grooves, dovetail grooves and other special-shaped grooves) and special-shaped surfaces. Coupled with the use of milling machine accessories such as indexing head, it can also complete the milling of workpieces such as spline shafts, helical shafts, and tooth clutches.

3. Milling has high machining accuracy, its economic machining accuracy is generally IT9-IT7, and the surface roughness Ra value is generally 12.5-1.6um. The precision of fine milling can reach IT5, and the surface roughness Ra value can reach 0.20um.
