Horizontal Milling Machine Work

Описание: Several short clips of jobs that I have done on my horizontal milling machine.

The first job was to clean up the bore of a pin hole on a newly made hydraulic cylinder. I was worried about this as the bar overhang was 7.5 times the bar diameter and usually the rule of thumb is to keep it under 5 times. To reduce the chance of chatter I used a piece of high speed steel with lots of rake angle and then honed it to a nearly razor sharp edge. This seemed to do the trick as the bar cut without chatter.

The second job was to chamfer some pressure vessel steel plates to prepare them to be coupons for weld testing.

The third job was on the horizontal milling machines own vertical head attachment. A threaded retaining ring had become seized and could not be removed. It needed to come out so the head could be disassembled, cleaned and rebuilt. It was then machined out and a new ring was made to replace it.

The final job was to saddle out some steel tubes to allow DOM tubes to be welded in place. The DOM tube is sitting on the end of the mill table. This was done after the vertical head mentioned above had been stripped, cleaned and reassembled with the new threaded ring.
