| 1) The tool is just deepening the hole, like in ordinary sinking, and does not make a thread. |
• The base foot wasn’t pulled down.
• The base foot wasn’t fixed well.
See page 10 step H on the manual
|
| 2) The tool descended the whole 42mm very fast and would not make any etching. |
• The scale wasn’t set, but rather left tightened and no horizontal movement occurred. Refer to page 12 stage J and set the scale.
See page 12 step H on the manual |
| 3) It seems that the thread is not concentric to the pilot hole. |
• Check first whether the thread is indeed not concentric – see below or, the case is that the process stopped in the middle – refer to 4.
• The centering process was made with scale screw not tightened - refer to page 10 F.
See page 10 step H on the manual
• The machine table moved after centering.
• The whole tool is not attached firmly. |
| 4) Only partial thread was produced. |
• The process stopped in the middle because the setting of the head descending was not done properly. Allow the head to descend 42mm (1.65”) after the base foot touches the table.
• The head reached its limit before ending the 42mm (1.65”). |
| 5) I am trying to center the electrode, but I have received different results when repeating the process. |
• The scale screw is not tightened.
• The whole tool is not attached firmly.
• The work-piece is not fixed. |
| 6) The etching process finished but the screw would not enter the thread. |
• The scale wasn’t opened enough. Open the scale some more.
• The electrode is worn, or the machine conditions caused fast electrode wear-out, especially at the tips. Open the scale some more or replace an electrode. See notes of replacing electrode during process.
See notes of replacing electrode during process – manual page 16 para. 2-2.1
• The electrode pitch is wrong – choose the right one. see … |
