Test of NIAGARA 3FL HP End mill for Aluminum

February 27, 2012, 11:02 pm by Eldar Gerfanov

Recenty ordered a 3Flute High Performance End Mill From NIAGARA.
Was very glad and slightly surprised that when punched in all of the endmill's data into my Calculator nothing broke down.I had a rason: At 5000RPM and 3/8" Deep slot cut. The feed came to around 92.0IPM. Chips were making this nice ringing noise that sounds like money.

Setup:
HAAS VM-3
Hudrolic Tribos Holder
3/4" 45DegHelix 3Flute 1.625FluteLen, 2.375"Overhang TICN HP End mill

S:5000RPM
F:92.0IPM
DOC: 0.375" Slotting
Coolant:FLOOD

The calculation was pretty much dead on.


Tapping Hardox Rc 45-50

February 27, 2012, 10:43 pm by Eldar Gerfanov

A need arouse to drill and tap lots of blind 1/4-20 holes in 3/4" thick hardox 45-50RC hard plate.

So if you ever need to do this use:

1) DRILL
Tap hole: >0.202" or bigger.  5/8 deep.
Drill used: Tialn coated carbide drill.
S=1418 RPM
F=2.6 IPM
NO Peck, No Coolant

2)TAP

Renishaw OTS tool probe cycle for HAAS can set both length and diameter offsets.

Too bad there is no choice: it only puts absolute measured diameter of the tool into D- diameter offset and makes wear offset=0

But if your programming is done with the center of the cutter, then you actually only need the difference between actual and programmed diameters of the tool.


I.E.: When probing 5/8Dia end mill, we get D=0.6248. You would normally have to subtract 5/8 from it and leave the -0.0002 difference.

But there is an easier way
