The milling machine is a machine tool primarily used for metal cutting, created in 1818 by a number of American mechanical engineers including Eli Whitney.
Machine column: Provides straight support. The column of some machines also provides the ability to move the headstock up and down.
Workbench: Supports and fixes the workpiece in processing. Some machines, such as sawing machines, also have tables that provide the ability to feed workpieces.
Saddles, beds (bases), slides, etc.: Support other components and sometimes provide freedom of feeding.
Computer Numerical Control (CNC) Master Machine Main Article: CNC Machine Tool and Numerical Control A CNC lathe with milling function.
The master machine can not only be directly operated manually, but also can participate in active control. Numerical control machine tools and more advanced computer numerical control machine tools have become an important part of the industry. The advantages and disadvantages of CNC Compared with traditional machine tools and special machines for mass production, CNC machine tools are more suitable for the production of a small number of or medium-volume high-quality CNC turning and milling composite processing quality fine parts, and are also more accustomed to the production of various products. Functional advantages: high accuracy. high quality. Materials are easy to store and modify.
Can be chamfered, chamfered, and bored. There are also carpenter milling machines, which are used to process various shaped surfaces and concave and convex grooves of wood. Machining time tool machines refer to power manufacturing machinery and equipment, which are generally used for fine cutting metals to produce other machines or CNC turning and milling composite processing. metal parts. To machine the workpiece, the machine tool creates a relative movement between the workpiece and the tool. This movement can be divided into main movement and feed movement.
CNC turning and milling compound machining
A metal is a substance with properties such as luster (strong reflection of visible light), ductility, simple electrical conductivity, and heat transfer. CNC machine tool refers to a machine tool that can perform active processing through accurate instructions modified in advance. At present, most of the numerical control machine tools are computer numerical control machine tools (CNC), and the computer plays the role of integrated control. In modern computer numerical control systems, the planning of workpieces is highly dependent on software such as computer-aided planning (CAD) and computer-aided manufacturing (CAM).
The computer-assisted manufacturing software analyzes the planning model and calculates the movement instructions in the processing process. Through the post-processor, the movement instructions and other auxiliary CNC processing single-piece instructions that need to be used in the processing process are converted into a format that can be read by the numerical control system. Load the files generated by the post-processor into the computer numerical control tool machine for workpiece processing. After inputting the program command into the memory of the numerical control system, it is compiled and calculated by the computer. Through the displacement control system, the information is transmitted to the driver to drive the process of the motor, and the CNC turning and milling compound machining is used to cut the planned parts. The above properties of metals are related to the free electrons contained in the metal crystal.
