Below are downloadable Simulation Files in DXF format (half-round line drawings) to accompany Harvey Tool products. Each file is specifically scaled to the geometry of the tool to help simulate running parameters and create tool paths. Like our speeds & feeds charts, these files will be continuously updated with the introduction of new products and new catalogs to assist operating the majority of our tools. Simulation files can also be accessed by searching for a specific tool number on the left-hand side of the website and then clicking on the Simulation table in the product table.

Rating StarRating StarRating StarRating StarRating Star   I have a 30K spindle...

By DD .. Ogden, UT, United States, March 17, 2014

but the .093 8x-loc is in my 14k machine... making super pretty side wall cuts... Would recommend holding these tools as tight as you possibly can, the axial pull is huge on these little monsters..

Rating StarRating StarRating StarRating StarRating Star   Solution to insufficient SFM

By James C. Peabody, MA, United States, January 13, 2014

After speaking with the tech at Harvey. We discovered the problem was not the SFM but the contact of the tool to the bottom of the slot. I was plunging .001 in the z depth to finish the bottom of the slot. While the tool is end cutting the face gash is very small and the .001 that I was plunging was just too much for such a small diameter to handle the solution was to ramp down very lightly and the tool worked fine. Great finish and no chatter.

Rating StarRating StarRating StarRating StarRating Star   Anyone have a machine that can run 29000 RPM

By James C. Peabody, MA, United States, May 29, 2012

I ordered the .078 5 flt with .406 loc. The reccomended SFM is 1000 as I am cutting 6061 with a chip load of .001/tooth. The machine I have can only obtain 14000 or 300SFM. I used a lower chip load .0005/tooth. The tool broke almost on contact. The holder I am using has only about .0003 runout so no it was not that. I seem to have better luck with the 3flt mills when I get that small. Anyone have any luck with these?

After receiving this review, a member of Harvey Tool’s technical team contacted James to discuss potential solutions for his application. The 3 flute tool was certainly a suitable solution for his slotting application, while one of our multi flute tools would be ideal for finishing his slot.
