A computer numerical control (CNC) milling machine is an advanced milling machine that automates the machining process by using a digital control system. It uses a rotating cutting tool (milling cutter) to remove material from a workpiece to create complex parts and assemblies. The operation of the CNC precision milling machine can be controlled by a special computer program, which reduces the need for manual operation and improves the accuracy and efficiency of machining.
The control system of a CNC milling machine consists of a program controller (PC), as well as digital servo drives and motors for controlling the movement of the axes. Designers can use CAD (computer-aided design) software to create product models and related production information and convert them into CNC programs. The custom CNC machining program includes instructions such as cutting path, depth of cut, cutting speed and feed rate, which can control the movement of the milling machine through the computer program.
The main advantages of CNC milling machines include high precision, high efficiency and flexibility. It automates a wide variety of machining tasks, including drilling, grooving, chamfering and curve cutting. CNC milling machines can also use a variety of cutting tools for processing, such as ball-end cutters, twist cutters and saw blades, etc., to meet different processing needs.
In conclusion, CNC milling machine is a highly automated processing equipment with the advantages of high efficiency, high precision and flexibility, and is widely used in industries such as automobile, aerospace, medical and electronics.
