Definition and Function of Programmable Controller for CNC Machine Tools
Programmable Logic Controller (PLC) is a new type of industrial control device based on microprocessor technology and integrating computer, automation, and communication technologies.
Programmable Logic Controller (PLC) is a new type of industrial control device based on microprocessor technology and integrating computer, automation, and communication technologies.
A programmable controller is an electronic system that operates through digital operations, using programmable memory to store programs internally, execute user oriented instructions such as logic operations, sequential control, timing, counting, and arithmetic operations, and control various types of machines or production processes through digital or analog input/output methods.
Programmable controllers have strong logical computing capabilities, and the input/output interfaces of PLCs meet the needs of industrial processes. They have the function of power amplification and can operate directly under load. This is why PLCs are superior to ordinary microcomputers in industrial control.
Function: - Complete various auxiliary functions
>The start stop, forward and reverse control of the machine tool spindle, as well as the control of spindle speed and the selection of magnification.
>Switching on and off the cooling and lubrication systems of the machine tool.
>The start and stop of the machine tool tool magazine, as well as the selection and replacement of the tool.
>Clamping and loosening of machine tool chucks.
>Opening and closing of automatic doors on machine tools.
>Start stop, forward, and backward control of the machine tool tailstock and sleeve.
>Control of auxiliary devices such as chip removal in machine tools
