Finished leveling the water drain channel
6 mm thickness of steel plate using a hacksaw
Testing the dial indicator, 0.01 mm unit.
Checking run out of the power drill’s shaft
Checking run out of the drill press’s spindle
The owner’s manual of Rexon DP-200A doesn’t explain about the run out limit of spindle. The run out reading of the drill press was between 0.01 mm and 0.02 mm. It was over 0.10 mm so I replaced the old bearing of spindle assembly.
Checking run out of the spindle assembly after replacing the old bearing. I made a mistake mixing new KBC bearing – 6203 – and old unnamed bearing, apparently which caused excessive run out of the spindle.
Rechecked run out of the spindle after assembly, which was between 0.02 mm and 0.03 mm.
