To those who suggest turning the OD,I gotta say give your
head a shake.Impossible
This "can " is 100 inches long and 30+ inches OD. 3/16 wall
thickness.The runout can easily exceed the thickness of mat'l.
Since it is rolled from plate, a nice OD means a nice ID.
Since "actual" diameter is...
My company is involved in the rebuild of a magnetic
drum separator.Why are we having trouble with the
actual "can"?
This drum is slightly more than 8 feet long and is
30.25 ID.Material is 3/16 thick stainless plate
It is very difficult to get an accurately rolled can.
We do have SOME latitude...
I have read this thread with some interest.The technique
of injecting manure into the soil could help with disposal
and contribute to soil quality.Does anyone have data on
soil tolerance to this injection?how much manure could be
placed per acre? Does the equipment exist to do this.
Thanks...
The most common formula for speed(RPM)is
4X cutting speed(of work material)
divided by diameter(of workpiece or cutter)
this is easily worked out mentally
Any machinist should be able to hit this tolerance.
Especially if it's a "one of" situation.
CNC equipment can repeatedly do this all day long.
If this is a regular lip seal,this tolerance req.is
probably a typo.Four tenthousandths is not necessary
for proper sealing action
