4. according to the position of the cutter body 6 on the workbench of the machine tool, a workpiece 10 to be machined is placed at a proper position of the workbench (safety must be ensured, the workpiece is forbidden to be placed at the edge of the workbench, otherwise, the machine tool needs to be replaced, and the machine tool with the proper area of the workbench is selected), and a main shaft of the machine tool is manually moved up and down, so that a positioning mandrel at the front end of the cutter body 6 is aligned to and inserted into a pre-hole of the workpiece to be machined;

5. locking a machine tool workbench, and then properly limiting and clamping the workpiece 10 to be processed;

6. starting the machine tool, starting the cooling liquid at the same time, moving a main shaft of the manual machine tool downwards, starting the processing of the counter bore, and setting a stroke limit on the machine tool according to the depth requirement of the counter bore;
