The contents and methods of geometric accuracy adjustment in the application of deep hole drilling machine are as follows:

1. The adjustment of sizing block and anchor bolt is mainly to adjust the geometric accuracy of the machine tool through sizing block and anchor bolt. If necessary, the accuracy requirements can be achieved by slightly changing the insert strip and pre tightening roller on the guide rail.

2. Adjust the relative position between the manipulator and the spindle and the tool magazine, so that the machine tool automatically runs to the tool change position, complete the tool exchange step by step manually, and check whether the actions such as tool grasping, tool loading, tool pulling, and rotation exchange are accurate and stable.

3. Adjust the relative position of the pallet and the exchange worktable This machine tool is a dual worktable or multi worktable. The relative position of the pallet and the exchange worktable should be adjusted to ensure that the worktable is stable and reliable during automatic exchange.

The application scope of deep hole drilling machine mainly includes the following three aspects:

1. Parts that are not easy to process on the general machine tool, or need to be equipped with complex special fixtures on the general machine tool and need a long adjustment time to process;

2. Parts that require small batch and multi batch production (generally less than 100 pieces), mold parts with complex curves and surfaces with complex contour shapes, high machining accuracy requirements or that must be solved by digital methods, and parts that are prepared for multiple retrofit designs;

3. Precise parts with high value that need to be jointly processed by multiple processes such as boring, milling, drilling, expanding, reaming, spot facing, tapping and can be completed at one time.
