From the original fitter, to general machine tools, to today39。s CNC machine tools, production operations tools in a rapidly changing updated. For finishing, a CNC turning, milling, boring, grinding, there are special processing, EDM。 while no margin for surface machining, you need to use a sandblasting machine. Blasting machine types can be divided into: suction blasting machine, pressureblasting machine, liquid sandblasting machine, sandblasting machine cooling. Currently, work is mostly sand blasting machines use relays, switches and buttons to control。 therefore, sandblasting machine there are some flaws. For example, relays, buttons, switches fatigue damage, susceptible to corrosion, malfunction, and many failures, sandblasting machine body is not good enough seal leakage could easily lead to abrasive recycling difficult, and environmental pollution. In summary, for the abovementioned drawbacks, in this design for sandblasting machine modern improvements。 with PLC, touch screen technology bined to modernize and improve its use and work to make it wider application, to conform to modern, intelligent control requirements. Sand in partment to absorb and reuse. In this design, the use made simple Mitsubishi FX series PLC, MCGS and touch screen bination of simulation intelligent control blasting machine is running。 take advantage of a variety of sensors for automatic operation.
