The Main Components Of CNC Machine Tools

Modern CNC machine tools are CNC machine tools, which are generally composed of CNC operating systems and machine tool bodies. The equipment specially used for processing metal or wood mainly consists of the following parts.

  • 1) CNC device: The computer numerical control device (ie, CNC device) is the core of the CNC system, which is composed of a microprocessor (CPU), memory, various I / O interfaces (interface), and peripheral logic (Logic) circuits.
  • 2) Numerical control panel: The numerical control panel is the control panel of the numerical control system, which is mainly composed of a display and a keyboard. Through the keyboard and display system management and CNC program (procedure) and related data input and editing (Editor) modification.
  • 3) Programmable logic (Logic) controller (PLC): PLC is a general-purpose automatic control device based on a microprocessor, used to complete various logical operations and sequences of CNC machine tools (attributes: automated machine tools) control. In numerical control processing, the control system sends out instructions to make the cutter perform various movements that meet the requirements, and expresses the processing of technical requirements and processing requirements such as the shape and size of the workpiece in the form of numbers and letters. It generally refers to the process of processing parts on CNC machine tools. In order to improve production automation, shorten programming time and reduce CNC machining costs, a series of advanced CNC machining technologies have also been developed and used in the aerospace industry. For example: auxiliary operations such as starting and stopping of the spindle, replacement of tools, and switching of anti-freezing cooling fluid.
  • 4) Machine tool operation panel: General CNC machine tools (attribute: automatic machine tool) are all equipped with a machine tool operation panel, which is used to perform some necessary operations on the machine tool in manual mode and to perform necessary interventions on the operation of the machine tool in automatic mode. Various required buttons and switches are arranged on it.
  • 5) Servo system: The servo system is divided into a feed servo system and a spindle servo system. The feed servo system mainly consists of a feed servo unit and a servo feed motor. CNC machining generally CNC machining usually refers to computer digitally controlled precision machining, CNC machining lathe, CNC machining milling machine, CNC machining boring and milling machine, etc. The feed route for finishing is basically carried out along the contour of its parts. Therefore, the work of determining the feed route is to determine the feed route for rough machining and empty stroke. It is used to complete various movements of the knife holder and the workbench. The spindle servo system is used for the spindle drive of CNC machine tools (attribute: automatic machine tools), which is generally adjusted by constant torque and constant power. To meet certain processing requirements, the spindle and feed drive can also be controlled synchronously.
  • 6) Machine tool body: The design and manufacture of the machine tool body should first meet the needs of CNC machining. It has the characteristics of high rigidity, high accuracy (accuracy), and can adapt to automatic operation. Because of the general use of stepless speed regulation technology, the machine tool The gearing mechanism of the feed motion and main drive is greatly simplified or even canceled. In order to meet the requirements of high-precision transmission, high-precision transmissions such as ball screws and rolling guide rails (TTW guide) are widely used. In numerical control processing, the control system sends out instructions to make the cutter perform various movements that meet the requirements, and expresses the processing of technical requirements and processing requirements such as the shape and size of the workpiece in the form of numbers and letters. It generally refers to the process of processing parts on CNC machine tools. In order to improve production automation, shorten programming time and reduce CNC machining costs, a series of advanced CNC machining technologies have also been developed and used in the aerospace industry. In order to improve productivity and meet the requirements of automatic processing, automatic tool holders and automatic fixtures that can automatically replace workpieces are also used.
