Shout out to NYCCNC for the blue tape method. It's saving me a lot of time with composites, which I was already gluing. The tape makes a better hold and way easier cleanup
Well Done! Talking through the cutting process is a really helpful learning tool. I need to try some Harvey Tools on my 1100 they are right down the street from me.
Grade 2 CP is soft as butter and not what people would cut if they are knife makers. Grade 5 TI-6-4 alloy is what people mean when they ask if it will cut Titanium. I was curious to know what speeds and feeds you'd use for that. On my 440 with flood coolant 10-15 IPM at 8000 rpm with 1/8 end Mills I get decent results. Flood is Mandatory on the alloys as they have very low thermal conductivity so heat dissapation is a problem.
Great question Robert! Grade 5 is a higher hardness, so we would need to back down the surface footage. Harvey Tool recommends a surface footage of 125 for materials in the 300-350 HBn range. Jason recommends leaving the chip load and everything else the same. We are planning on cutting more titanium, including some 6Al-4V in future videos.
Out of curiosity how come you don’t run flood coolant? Most of your videos you use a mister. I have a CNC Bridgeport clone and I run lots of coolant. I made a pump system out of a sump pump.
It is preferable to run coolant when cutting titanium, but we run the fog buster on this for clarity in the video. The fog buster did a good job, but coolant would have prevented us from burning up a tool.
Interesting. A huge 'waste' of material and time. Very impressed with the Harvey tooling. The details of machining the titanium are very informative, and watching that tool go cherry and toast from chips was very interesting. Certainly a challenge to make a name plate, but making a mechanical part is far more satisfying since you could have made the name out of aluminum. Great video.
That was a SMW fixture plate! It isn't a standard option with the M series, but they are available on our website... www.tormach.com/store/index.php?app=ecom&ns=prodshow&ref=38209
