  1. Re: Finishing passes with 1/2" carbide ball end mills in steel

    That's not a bad idea, I'll talk to a local supplier and see what they recommend for the job. Thanks again for the insight, you've been very helpful.
  2. Re: Finishing passes with 1/2" carbide ball end mills in steel

    Thanks for the in depth response! I actually intend to leave the machined finish on the blade if I can get it smooth enough.

    Unfortunately my Tormach doesn't have the ability to tilt it's head,...
  3. Finishing passes with 1/2" carbide ball end mills in steel

    I'm trying to run toolpaths in some high carbon stainless steels to make knife bevels, hardness is about 255BHN. I'm getting my speeds/feeds from Gwizard calc, running a Tormach 770 for my mill,...
  4. Speeds and feeds for 1018 steel are chipping my endmills!

    I'm using GWIZARD calculator to get my speeds and feeds. Haven't had any problems until last night. I tried to cut some 1018 hot rolled steel at 2mm deep with a half inch thick, four flute TiAIN...
  5. HELP NEEDED! Slotting Tool steel, worried about chipping tooling.

    Like the title says! I'm working with annealed CPM-M4 tool steel, whose PDF detailing it's physical properties can be found here. I've been using the GWizard calculator for speeds/feeds for prior...
  6. 1095 steel stock bowing after facing .25mm

    As the title says. I am working with 2" x 10" x 5/32" 1095 steel, the stock is very flat before beginning work. However, after the first side had 0.25mm faced off, I noticed a severe curve, as the...

    Re: Question about vise jaws

    For now it's only a few pieces, but I'm expecting this to become somewhat routine soon. I'm not set up as a machine shop yet, and right now this is more of a hobby than anything else. All the same, I...

    Re: Question about vise jaws

    That... actually sounds like it could work fairly well, but I wouldn't want too much upward force, as the plate is getting milled down a decent amount.



    Glad to hear. Would 6061 aluminum be...

    Re: Question about vise jaws

    Those look like they'd be very useful, but I'm just considering the vise jaws for the time being, as I don't have the time to setup a new pallet system right now. However, they look like they'd be...

    Re: Question about vise jaws

    That was my first idea, CadRhino, I originally wanted to get a second vise to compliment my first, but it looks like that particular model is sold out, and I haven't had any luck finding any locally....

    Re: Question about vise jaws

    Looks like they have a 7" long version I could try. The appeal of making them myself is that I could have them made and ready to go faster than I could get Monster-Jaws to ship them to me, and a lot...

    Question about vise jaws

    Ok, so I tried facing a 10" long plate of aluminum on my 5" vise, and got some pretty severe chatter. Tried with steel before, didn't have a problem.

    I wanted to ask if making new 10" step jaws to...

    Re: Superfly cutter issues; mild steel

    Good advice on the set screws! For width of cut, I was using the full width of the fly cutter, with the bar set at its shortest length, 2.5". My stock had some mild scale of some kind but didn't give...

    Re: Superfly cutter issues; mild steel

    Thanks for the suggestion; speeding it up to 1750rpm seems to have done it! I just need to adjust my depth of cut to avoid another hangup (I'm doing something a little weird with my tool pathing, one...

    I am having problems getting my superfly cutter working with my 770 machine and some low carbon steel, and was hoping someone may have some insight.

    I'm trying to face my stock before I begin work...
