Is the clear specification for discussing the drilling volume of CNC cylindrical grinders clear?
Reasonably clarifying the drilling volume of CNC cylindrical grinders is of great practical significance for increasing labor productivity and ensuring production and manufacturing quality. Generally speaking, drilling is a precision machining production process. Compared with other milling methods, its milling efficiency is much higher and lower. Excessive surplus will reduce cost and efficiency, and increase the power installation project consumption of sand wheels and machining centers.
In some cases, the quality of the parts may continue to decrease again, such as for cast iron parts that have undergone surface high-frequency quenching and high-frequency heat treatment. Their surface compressive strength is high, but the compressive strength decreases as they move inward. If the volume is large before polishing, the compressive strength of the surface after drilling does not meet the requirements. Of course, the volume cannot be set too small, otherwise the production scratches or defect layers left by the previous process flow cannot be ground off.
Therefore, the basic premise for clarifying the drilling volume of CNC cylindrical grinders should be that, while ensuring the surface quality of cast iron parts after drilling, the lower the drilling volume, the better. Due to the complexity of factors affecting cutting speed, it is not possible to establish a unified method for using electronic computers. Generally, adjustments are made based on relevant manuals, tables, and specific on-site conditions. When drilling the inner hole of the roller bearing ring, due to the fact that both internal threads are drilled and manufactured, attention should be paid to the distribution of volume on the surface of both ends during the machining process, in order to reasonably remove the drilling volume of each internal thread.
