Importance of Repeat Positioning Accuracy for CNC Automatic Drilling Machines
In the operation and processing of CNC automatic drilling machine, repeat positioning accuracy plays a crucial role, which directly affects the processing quality, production efficiency, cost control and the overall performance of the equipment. From the point of view of processing quality, repeat positioning accuracy is the key to ensure the consistency of parts. When the CNC automatic drilling machine for a batch of the same parts for drilling processing, if the repeat positioning accuracy is high, then the positional deviation of the corresponding holes in each part will be very small, and can strictly comply with the requirements of the design drawings. This is particularly important for those parts with assembly requirements, such as in mechanical assembly, multiple parts of the holes need to be accurately aligned in order to achieve a good fit, if the positional deviation of the holes is too large, it will lead to difficulties in assembly, or even can not be assembled, which seriously affects the quality and performance of the product. On the contrary, if the repetitive positioning accuracy is low, the position of the holes on the parts will have large fluctuations, which will not only reduce the product qualification rate, but also may lead to the subsequent process can not be carried out normally. In terms of production efficiency, high repetitive positioning accuracy can reduce unnecessary adjustment and inspection time. When the repetitive positioning accuracy of the equipment is guaranteed, the operator only needs to carry out an accurate tool setting and parameter setting before mass production, and the subsequent machining process can be carried out stably without frequent downtime for adjustment. If the repeatability of positioning accuracy is poor, every few parts may be processed because the hole position deviation exceeds the standard and need to stop the machine to…
