With the continuous development of science and technology, higher and higher requirements are put forward for the quality and productivity of ceramic machinery products, and the upgrading of products is also accelerating. Therefore, the transformation of CNC machine tools is more important. The design of CNC machine tools And transformation has also become an important aspect of industrial development. Milling machines Al2o3 Ceramic are widely used, mainly for machining or forming surfaces. To process special planes such as arcs and cams on a vertical milling machine, it is necessary to use machine tool accessories such as a circular table and an indexing head, and to adjust the machine tool as a whole. The machining accuracy is low, and the basic adjustment work is laborious. Therefore, in order to improve the machining accuracy of the workpiece, ensure the quality of the product, and facilitate the processing of the arc surface and the curved surface of the cam, the CNC method can be used to carry out the numerical control transformation of the milling machine. Conditions for NC Transformation of Ordinary Milling Machines
Not all ordinary machine tools are suitable for CNC retrofit. The modified machine tool should meet the following conditions:
The basic parts of precision machine tools must have sufficient rigidity
CNC machine tools Al2o3 Ceramic are high-precision machine tools and require high moving accuracy. Usually the pulse equivalent of a closed-loop system is 0.001mm, and the pulse equivalent of an open-loop system is 0.005mm or 0.01mm. High positioning accuracy and contour machining accuracy require that the basic parts of the machine tool have high dynamic and static rigidity. If the rigidity of the basic parts is not good, it is easy to deform after being subjected to force, and this deformation has great uncertainty, so the numerical control system cannot be used. compensation function in . Therefore, the machine tool with poor basic rigidity is not suitable to be transformed into a CNC machine tool.
The cost of ceramic renovation is reasonable and economical
The cost of machine tool renovation is divided into two parts: machine tool and electrical. On the one hand, it is to repair and modify the original machine tool part and replace the worn parts; on the other hand, it is to replace the original machine tool control cabinet and replace it with a new numerical Al2o3 Ceramic control system and a strong electric device. The cost of transformation is related to how much the original machine parts are used and what kind of control system is used. Due to economic considerations, economical CNC systems driven by stepper motors are usually used for machine tool transformation. How much the total cost of transformation is appropriate depends on the user. Generally speaking, it is economically appropriate if it does not exceed half the price of equipment with similar specifications.
