The CNC machine tool manipulator will change, amplify and adjust according to the received displacement and speed instructions, and then transfer it to the motion unit. The running status is detected in real time through the optical fiber sensor. During the high-speed handling process, the moving parts are in a very short time. It can reach a given speed within a high-speed stroke, and can stop instantly in high-speed travel. Through the interpolation operation of a high-resolution absolute encoder, the influence of mechanical errors and measurement errors on motion accuracy is controlled. Because the workpieces to be conveyed are different and the quality is also different, there are many specifications and series of CNC machine tool manipulators. When selecting, it is selected according to the quality of the conveyed workpiece and the processing beat. However, the arm of the manipulator and the clamping method are designed according to the shape and structure of the workpiece to be conveyed and the clamping method of the machine tool fixture.
When choosing a CNC machine tool system, a variety of factors need to be integrated, such as the use environment, workpiece conditions, processing technology, procurement budget, etc. For example, when choosing a three-axis vertical machining mold, you can choose Fanuc0iMD-A or Mitsubishi M70-A to process the product. At the time, you can choose Fanuc0iMD-B or Mitsubishi M70-B. It is recommended to choose Siemens 840D or Fanuc31i when choosing the five-axis overtime system. If it is used for teaching, you can choose the five-axis of Huazhong or Guangshu. In occasions where processing requirements are not high and budgets are limited, domestic CNC systems or Taiwan systems can be selected.
According to investigations, poor lubrication is one of the main causes of premature bearing damage. The main reasons include: not filling lubricant or lubricant in time; lubricant or lubricant not filling in place; improper selection of lubricant or lubricant; incorrect lubrication method, etc. Recommendation: Choose the correct lubricant or lubricating oil, and use the correct lubrication filling method. Contamination can also cause premature damage to the bearing. Contamination means that sand, dust, metal chips, etc. enter the inside of the bearing. The main reasons include: opening the bearing package too early before use, causing pollution; the working environment is not clean during installation, causing pollution; the working environment of the bearing is not clean, and the working medium is polluted.
