What Is an NC Milling Machinery?
NC (Numerically Controlled) milling machinery is a type of NC machine tool used in metalworking. These machines are controlled by an arithmetic device, allowing for automated and precise operations. Machining programs are pre-loaded into the machine, enabling the production of high-precision workpieces. Milling refers to the process where the tool rotates to cut the material.
Uses of NC Milling Machinery
NC milling machines are primarily utilized for metal cutting tasks. Equipped with a computerized NC control system, these machines can process multiple parts uniformly, reducing variations caused by different operators. This capability is particularly valuable for machine tool manufacturers and mold producers who require high-volume, consistent output.
Principles of NC Milling Machinery
The NC milling machine comprises an “NC device” for machine control and an “NC program” for command execution. The NC device is responsible for translating processing instructions into machine movements.
This device includes a panel for operator interactions, a central unit for numerical calculations, a sequencing mechanism for sensor and peripheral device control, and a servo mechanism for precise movement control.
The central part of the NC machine tool employs numerical operations based on the “G code,” a programming language consisting of simple commands and coordinates. The sequencing mechanism ensures the correct operation of sensors and peripheral devices, while the servo mechanism controls the servo motor, directing the machine to the required cutting position and speed.
