hi all,

this situation is on a surface grinder.

sometimes i get this assingments, where i have a 3 step type tooling part.
1st step is @ .5000 second step at 1.0000 and the 3rd step @2.0000
and they have to be within .0005 and this involves side wheeling each step also, but i need this for the step part of it.

have you, or do you know of a none mag base i can attach my test indicator to, and slide it back and forth from the .500 gauge block and then onto the part for accuracy while the mag on chuck is it on?

or maybe how do i go about making one of something that is non magnetic

thanks all

Use a mag base with the magnet turned off. For better accuracy use a height
gauge.

hi all

i cannot release the magnet on the chuck, this is a surface grinder.
i want to be able to move my test indicator back and forth from the gauge block and the tooling im trying to measure.

having a mag base on off , the chuck on the surface grinder will suck it down cause its on.

any other suggestions

any material maybe i can glue onto the base that is not/or will get magnitized??while the chuck is on.
thanks all

Why don't you put your DTI onto a mag base and clamp it to the wheel guard, and
indicate the piece from above by traversing the table?

Make up a composite disc formed of a disc of 1/4" mild steel
stuck to a 1/.4" disk of brass or light alloy.

With the mag base turned on the mild steel side will stick to
the mag base and the brass side will happily slide on an
energised mag chuck.

Every time the spindle is moved down for a grind you lose your reference.

original poster stated he was using a gage block to compare the heights
, so clamping to the wheel guard is quite workable
