Bearing Sleeve with Radius Formation ID

09/21/2009 1:34 AM

Dear all,

Well i have to manufacture a bearing sleeve with process involving cutting, machining, Marking, Heat Treatment, External and internal grinding.

I have a problem in internal grinding. I need a radius of 5240 in ID and also to finish its length at the same time.

Can any one suggest me a tooling to do this operation with machining or grinding process.

Hello there,

Is the radius .5240". Would you consider Die sinker EDM and final polishing. The electrode manufacture and the EDM process is easy to control as you can measure with gages etc as you go.

With a really fine finishing cut you will have little recast layer from the EDM and the material removal during polishing is very predictable.

Good luck.
