PSM series rubber roller lathe grinder is specially designed and manufactured to replace the past roller processing method by metallic manufacturing equipment. Mounted grinding head on the engine lathe is the past method to manufacture roller, which the quality of roller is difficult to reach the requirement of the present standard. The main reason lies in the structure of lathe. After all, it is not the grinding machine; the moving spaces of the big and medium carriage table are larger than that of grinding machine. Therefore, vibration may be produced while in the grinding processing, which will generate ripple at the surface of processing rollers. Further, due to the width limit of the guide-rail of lathe, the way of mounted grinding head is hardly to ensure the stability while in operation.
The structure of PSM series lathe grinder is to be designed to make up for the shortage of present lathe. By means of assembly two medium carriage tables, the grinding machine enjoys the advantages of more functions than engine lathe and its performance and operating stability have reached the accuracy requirement. Then why the modern rubber roller professional manufacturing technology gradually stops to use cylindrical grinding machine? It is because of the low rotation speed of grinding wheel, the linear velocity is only 40m per second. That is the reason that causes low production efficiency. Further, while in grinding the stiff and wearable rubbers, and when the grinding from one side to the other, the geometric size of both ends of roller is hardly to keep consistency due to the abrasion of vitrified abrasive wheels. The generating heat in the course of grinding will be accumulated in the vitrified wheels which are difficult to radiate, therefore, the vitrified wheels have the hazard to explosive, more seriously, and it may cause fatal accident.
PSM series lathe grinder adopts high-speed grinding head, equipped with the first-grade alloy grinding wheels for rubber, the permissible maximum linear speed can reach more than 90m per second. Not only the production efficiency increases, but the geometric size of the roller’s surface is also can be guaranteed. As for the surface finish of rollers, it can be realized by adjusting the speed of grinding wheel. Moreover, while in the processing, the online measuring is also a kind of highly specialized skill. For the roller is an elastic body, even with the same measuring tool, the various people can get different value, errors would occur. For the purpose to overwhelm the difficulty, the advanced measuring device is assembled on the PSM series grinding machine, not only it can timely measure the size of processed parts, but also can provide effective help to control the grinding size. In a word, PSM series grinding machine is ideal professional equipment for the modern processing of rubber roller.
