Title: Flycutter / Boring Head - not for the faint hearted
Post by: John Stevenson on January 02, 2010, 10:05:03 AM
Thought I'd post this as an example of working outside the box.

Some while ago whilst working sub contract for an engineering company we sent a large steel plate out to be faced and have a large locating pin hole bored in and an 'O' ring groove for a seal machined in.

When I came back and we came to assemble it [ against the clock as usual ] we realised that the 'O' ring groove had been missed out. this plate was far to big to go on any of our machines so I came up with this.

Big steel disk with a 5/8" shank screwed and pinned into the back face, onto this was bolted a scrap top slide off a Myford ML7 with a tool block / holder  screwed to this.

This was fitted to a large magnetic drill, clamped for extra safety  and lined up on the plate and the groove machined in.

Worked a treat and provided the revs were kept down it works well.

I wonder if there is an eqivelent in metal machining to what we used to do
when I served my time as a joiner when starting a machine up with new cutters orsomething a bit different  we would always get a Piece of 9 x 3 x 3ft long and place in front of any cutter block on spindels when starting for the first time , it would not have stopped it but ( bit like tv when they get behind a car door when someone is shooting a 357 magnum at them)  you felt better.
