Lathe, small i.d. gooving

[Threept82]

Hi Guys,

I need to put in a .060 wide x Ø.220 i.d. grv

in a part that needs to be .760 deep. I have a Ø.198 dia. hole. Doe's anyone in MC Lathe land know of any place that has solid carbide groove bars that would accommodate this? Micro-100's smallest is a min. hole of Ø.250.

Iscar PICCO R005.0150-20

 

.197 min bore

.039 max groove depth

.827 deep

.059 wide groove

 

We use these PICCO series from Iscar all the time. If they don't have what you want its pretty easy to modify them.

Thanks MichaelJ.

Looks like they have one I can modify a small bit to work.

I've got a similar part and I use the .250 micro-100 bars and then grind down the backside so they'll fit in a smaller hole. Kinda ghetto but it works!

My kind of tooling. I'll look in to that. (up in the hood)

Circle is another option for small holes; that's pretty much their bag.

 

Scientific Cutting Tools will custom make you pretty much anything you need but the delivery is more suited for repeat jobs than one-timers.

Look in the PH Horn catalog. It's a German company that has really great micro I.D. stuff for lathes. They have a system that clamps their small tools that you can take out the boring bit and put it back in and bore a hole and it's within .0001 of the previous hole size.
