Deep hole boring machine manufacturers think that there are possible reasons for errors in the processing of deep hole boring machine. The manufacturing error of deep hole boring machine. The manufacturing errors of deep hole drilling and boring machine mainly include spindle reversal error, guide rail error and transmission chain error. Spindle reversal error refers to the change of the practical axis of the spindle in each instant relative to its uniform axis, which will directly affect the accuracy of the workpiece to be processed.
The main causes of the spindle reversal error are the coaxiality error of the spindle, the error of the bearing itself, the coaxiality error between the bearings, the spindle winding, etc. The guide rail is the benchmark for confirming the relative orientation of the components of the deep hole boring machine on the deep hole boring machine, and also the benchmark for the movement of the deep hole boring machine.
The manufacturing error of the guide rail itself, the uneven wear of the guide rail and the quality of the device are the important factors to form the guide rail error. Transmission chain error refers to the relative movement error between the transmission elements at both ends of the transmission chain. It is caused by the manufacturing and installation errors of each component in the drive chain, as well as the wear in the use process.
Several errors of the tool. Any tool will inevitably wear in the process of cutting, which will lead to changes in the size and shape of the workpiece. The influence of several errors of cutting tools on machining errors varies with the variety of cutting tools: when selecting fixed-scale cutting tools for machining, the manufacturing errors of cutting tools will directly affect the machining accuracy of workpieces; while for general cutting tools (such as turning tools), the manufacturing errors have no direct impact on machining errors.
