When designing the control circuit system for a CNC lathe manufacturer’s press, it is essential to base the design on functional requirements while fully considering factors such as user safety, ease of maintenance, and good production performance. The key focus is to ensure the reliable and safe stopping of the press, and to develop a plan for the control circuit system. Below is an introduction to the control circuit flow by the CNC lathe manufacturer:The plan for selecting the control circuit system must ensure that once the press receives a stop command, it will quickly cut off all power, swiftly and correctly disengage the clutch and brake, and ensure that all components are unable to start a stroke in case of a fault. If any component of the control circuit fails during the downward stroke of the ram, the punch will stop working immediately, preventing the ram from continuing to descend. While meeting the punching function and ensuring safety, the control circuit system should be simplified as much as possible to minimize both the quantity and variety of components used. Below are some typical control circuits that illustrate the requirements for functionality and safety in CNC lathe control circuits.
The control circuit for the initial punching operation is relatively simple. This circuit only meets the four operational methods that a press should generally satisfy: single stroke, automatic stroke, continuous stroke, and jog stroke, without considering more thoughtful issues.Based on the operational characteristics of a single stroke and the requirements for various pressure processing, designers seek an ideal safety control system, which is not only an important goal but also a good opportunity to showcase their technical skills.To this end, many designers have put considerable effort into the design of the control system and have gradually improved the control circuit system based on continuous summarization of production and practical experience.
