Quality of carbide now as compared to 2 years ago
The overall consistancy of carbide in newer inserts, endmills, and tooling of all types from mutiple companies seems to have gone down in quality over the previous months. Talking to techincal support lines about suggested feeds, speeds, depths of cut, and even what type of holder to put the tool into has done little to avoid snapping inserts and endmills. Doing as technicians suggested ,verbatim, it may work or not at first .
Then the tool breaks down from suggested feeds to fast or snaps an endmill on contact with to metal to be machined due to poor carbide chemistry. Tooling Co's say order another tool same exact tool and the tool screams and has all sorts of vibration that loosens the holder pulling the tool out. FRUSTRATED we finally just had to cut the part with an older tool we had lying around the shop with much slower feeds and speeds.
It just seems that maybe do to the recession and competition that tool companies are cutting costs? BUYING THE WRONG
CARBIDE BLANKS!
