  in the topic CNC machine tools in the forum Suggestions

  Compared with ordinary machine tools, CNC machine tools have the following characteristics: ●High processing accuracy, with stable processing quality; ●It can carry out multi-coordinate linkage and can process parts with complex shapes; ●When the processed parts are changed, generally only the CNC program needs to be changed, which can save the production preparation time; ●The machine tool itself has high precision, large rigidity, can choose favorable processing amount, high productivity (generally 3~5 times of ordinary machine tools); ●The machine tool has a high degree of automation, which can reduce labor intensity; ●Higher requirements for the quality of operators, higher technical requirements for maintenance personnel.     https://jvanplant.com/cnc-turning-service/ تم إجراء تعديل على هذة المشاركة بواسطة : h921732261 ، في : ١٨ نوفمبر، ٢٠٢٢ ١:٠٧:٣٢ ص PST

  1.CNC machine tools and CNC systems The meaning of CNC is computer numerical control. 1. CNC machine tools (1), metal cutting for hole machining, tapping, boring, milling, turning, thread cutting, cutting plane, contour machining, surface grinding, external cylindrical grinding, internal cylindrical grinding, etc. (2) Wire electrode cutting machine. (3) Punching, step punching, stamping, metal forming, pipe bending and other machine tools. (4) Industrial robots. (5) Injection molding machine. (6) Detection and measuring machine. (7) Woodworking machinery. (8) Special material processing machinery: such as processing stone, glass, emission minerals, etc. (9) Special processing machinery: laser processing machine, gas cutting machine, welding machine, drawing machine, printing machine, etc. With the development of electronic technology and computer technology and IT technology, at present, these machine tools and processing equipment can be controlled by numerical computer with numerical data, called CNC control.

CNC system The meaning of CNC system is computer numerical control system.  The CNC control of the machine tool is a comprehensive control technology that integrates multiple disciplines.  A CNC system includes: (1), CNC control unit (numerical controller part). (2) Servo drive unit and feed servo motor. (3) Spindle drive unit and spindle motor. (4) PMC (PLC) controller. (5) The input/output (I/O) unit of the control signal of the strong electric cabinet (including tool magazine) of the machine tool. (6) Machine tool position measurement and feedback unit (usually included in the servo drive unit). (7) External axis (mechanical) control unit. Such as: tool magazine, exchange table, loading and unloading manipulator drive shaft. (8) Information input/output equipment. Such as computers, disk units, memory cards, keyboards, special information equipment, etc. (9) Network. Such as Ethernet, HSSB (high-speed data transmission port), RS-232C port, etc. and the local area network of the processing site. Excerpted from Plastics Forum Details can be found on Baidu Encyclopedia...  The hardware of the CNC unit (controller part) is actually a dedicated microcomputer. It is the core of the CNC equipment manufacturer's own design and production for the control of machine tools.
