Grinding HSS to use in Jones and Shipman Holders

(1/2) > >>

appletree:
Hi I have a number of J&S and Armstrong tool holders which take 1/4 square HSS bits. Does anyone know of any data on optimum grinding of HSS to use in these holders? I use indexible tooling or 1/2 inch square most of the time but I do like the adaptabi;city of HSS. Phil

RobWilson:
Hi Phil


The tool profile all depends on what material your turning and whether its a finishing or roughing tool   :dremel:   so giz a clue  :)


Rob

Also is there any relief angle already built into the tool holder ?

appletree:
Hi Rob,I knew that would come back to bite me, I thought when i posted and I fully appreciate the question and the reason for it. Mostly I machine aluminium and fairly free machining stainless, what I was asking is if there were any J&S data sheets which take in the inbuilt angles in the holders. Phil

 :Doh: WHAT A CLOWN ! ,,,,,,,,,, I forgot to upload the photo/attachment  Phil


Just stick a tool bit in and you will see if there is any built in relief angle .

Thanks for that Rob will have a look at the inbuilt angles, I have one of those digital angle gauges, will do some measuring. Phil
