I just recently Finishing restoring an Enco BP Clone for the shop and am a new to milling. I have had a lathe for years and am understand feeds and speeds ect. The machine is in almost new shape, .005 or less backlash in the screws, Hard chromed ways with no wear, Nice and tight. 5hp 3phase motor on an allen bradley VFD, so HP is not a problem with this girl,
Most of what i do is general Repair and one off parts, Mostly work in steel.
I have worn out several HSS end mills on the last couple parts i have made and there has to be a tough general ruffing tool that will work well with out scraping an expensive end mills.
The last parts i just did were Cast iron someone had nickel welded steel reinforcements over a crack, I milled all the crap back to the original surface with a Niagara cutter Ruffing HSS end mill and it was dull by the end.
I also did some buildup TIG brazing Aluminum bronze to build up missing tabs on a wells band saw guide arm. And it ATE end mills. Like an average or 2-3 mins of cutting before totally destroyed.
On the lathe i use Sharp Brazed carbide tools for things like this and have a carbide grinder to resharpen then and it cost next to nothing to do things like this, But at $20-30 each for a good end mill it costing a lot in tooling to machine this stuff. I got this job done but got to be a better way.
I have a 2in facing mill with round incerts that works great but on this stuff there was no to get into tight ares with it.
Any recomendations for a good general pourpse tool for jobs like this?
