Avoiding Retapping at Assembly line
In heavy machinery parts we often use M10~M42 taps in various components and they are kept in queue in paint shop, cr plating shops or in stores for weeks.
When we try to assemble the same in assembly bolts are not entering
causes:
1) Dust and other particles inside.
2) Cleaning is tough in tapped holes
Effect :
1) Retapping - leading to oversize of threads,
2) Assembly time lost.
Options tried:
1) Plastic plugs - Costly (equal to steel plugs- when bought in low volumes)
2) Steel plugs (if not properly stored threads get damaged and spoils thread in next jobs)
Do we have any good solution to avoid this NVA.
Is there any tool for truncating small ID threads !
[QUOTE=Georgefam;10958]Kelly is right. Any material on the threads will create a problem. Another solution might be to cut threads after coatings have been applied.[/QUOTE]
Do we have any possibility and tool to truncate the internal threads weak starting threads.
