Engraving machine controller
The engraving machine control system, the core part of the engraving machine, is the brain and the soul. A good body is available with a good bed. To make him move and create more profits for you, you need to give it a smart brain, a pure soul. The controller has three parts, one, the driver, the inverter, the engraving controller and the host computer software.
1, the driver, its function is to accept the pulse signal provided by the controller to drive the stepper motor motion. One of the main functions of the drive is pulse subdivision. Each stepper motor produces a complete square wave pulse signal that produces a fixed step. Take a common two-phase hybrid motor as an example. Each time the motor receives a pulse signal, it produces a step angle of 1.8O. It takes 200 steps to rotate the motor one revolution. But when the drive is subdivided, it takes 200*8=1600 steps per revolution. It is further inferred that when the linear displacement of the conduction device per revolution is 10 mm, the pulse equivalent is 10 mm / 1600 pulses = 0.00625 mm / pulse. This is the theoretical minimum engraving accuracy of this machine.
2. Inverter, its main function is to accept the controller signal and output high-speed pulse device. As we all know, the mains used in our country is 50HZ. The main function of the inverter is to adjust the running speed of the spindle by adjusting the power supply frequency. There are many suppliers of inverters, and the main brands in the industry are Fuling and Sifang.
3. The engraving machine controller is the core part of the engraving machine control system. His main function is to execute computer software commands and control the drive, the drive works. The earliest people blindly worship imported products, such as: Siemens, Fanak, Baoyuan, new generation, etc., but as practice found, these powerful CNC machine controllers are not very practical for engraving machines. Now more end users prefer domestic products because it conforms to the working method of the engraving machine and is more user-friendly. The best supplier of engraving machine controllers in China is Jinan Exhibition Company. Its product stability and speed are very good, the biggest advantage is the extremely high cost performance.
What are the accuracy of the engraving machine?
The method of judging the engraving quality of the engraving machine is mainly observed from two aspects, one is the accuracy of the size, and the other is the roughness of the surface. Many factors will affect the quality of the engraving machine. Experienced operators have summarized this in their long-term work experience, which can help us effectively avoid these conditions and improve processing efficiency and quality.
First, the tool is one of the main factors affecting the processing quality of the engraving machine. There are many types of engraving machine tools. We should choose the tool suitable for the current machining material when selecting, and at the same time ensure the quality of the tool. The tool with poor quality not only affects the props. The service life will also be insufficient due to the lack of sharpness.
Second, whether the use of cutting fluid will also affect the quality of engraving machine engraving. The cutting fluid mainly functions to lubricate the tool and the workpiece, and also has good cooling performance. The application of the cutting fluid can greatly improve the processing efficiency, and the friction and resistance during processing are reduced, so that the processing surface is processed more. For the delicate.
Third, the rigidity of the process system, the rigidity of the fixture, machine tool, workpiece and tool. It also determines the accuracy of the engraving machine, and the rigidity of the tool will not affect the overall processing effect. The choice of tool is determined by the material being machined.
Fourth, the system is set up. Now the engraving machine we are applying is generally the CNC engraving machine controlled by the computer numerical control system. Check whether the parameter setting is correct, whether there is no problem with the setting of the route, and whether the setting of the speed is appropriate, these will affect the engraving machine. The quality of the engraving is accurate.
In addition to the above mentioned points, there are many factors that will have a certain impact on the quality of the engraving, such as the occurrence of downtime, power failure, rail jam and other external factors.
