CNC Milling is to use the rotating multitool to cut workpieces, such processing method is efficient. Tool rotate (background) while working, and the workpieces move (as a feed movement), workpieces can also be fixed, but at the moment, rotate tool must also move (at the same time to complete the main motion and feed motion).Milling machine has a horizontal milling machine or vertical milling machine, large gantry milling machine.The machine tool can be ordinary machine tool, can also be a nc machine tools. With rotating cutter as a cutting tool.Milling is generally conducted on milling and boring machine, suitable for processing plane, groove, all kinds of forming surface (such as spline gear and thread) and special shape mould surface, etc

After the production is completed, the company will add 360,000 tons of polyvinyl chloride resin, 300,000 tons of ion-exchange membrane caustic soda production capacity and 175 million kWh of electricity generation capacity each year. After the project is put into production, it is expected to achieve an annual operating income of approximately 2.99 billion yuan, and an average annual after-tax net profit of approximately 500 million yuan.
The characteristic of the CNC Milling is:
(1) cutter blade periodically participate in continuous cutting.
(2) each blade in the process of cutting, cutting thickness is variable.
(3) each tooth feeding alpha f (mm/teeth), said cutter every turn a blade workpieces relative displacement of time.
