  1. Re: What is the minimum ceiling height needed for an 1100?

    Depends on if you need their stand or full enclosure. The starter package is just the bare mill with no base or enclosure. That's how I bought mine. I built a stand to save money and ended up...

    Re: Endmills with Longer Cutting Length

    Resurrecting and old thread, but SpeTool on Amazon has 1/8" O-Flute carbide bits in 3/4" (5pack $25) cutting length. Since they are single flute they don't pack up with chips as bad. You would have...

    Re: bits 1/8 vs 1/4

    ummm, still not sure what type of answer you are looking for. My CNC has 100x more side load than a handheld router would ever see.

    The strength of the bit is the cube of the diameter. So a 1/4...
  4. Re: Newbie questions regarding aluminum cutting

    Shapeoko could produce molds as long as you were ok with low tolerances and a lot of hand finishing. Something like a prototype fishing lure where exact dimensions aren't critical. You could end up...
  5. Re: Flat end turns melting hot on machining rusted steel

    There is a huge difference in speeds and feeds depending on the type of steel and heat treat condition. 300rpm should be fine. If that's AR500 plate you are work hardening it instantly. If it's just...

    Re: CNC Cutting Aluminum - Newbie Question

    It all depends on what you mean by precision. You can't make in in this business without exact dimensions and tolerances. To many 1/100th of an inch is more precise than they have ever seen, a...
  7. Re: I need Help with Carbide Tool Nomenclature - Designations

    DC11, TC11 are how some Chinese vendors label the inserts and it's not correct. The proper designation is something like DCMT11T302N
    There are two different naming systems, ANSI and ISO. ISO is...
  8. Re: Machining out parts, how long to do each part

    Just the time per part?, not including them time to cad them up, generate the cam, and create any needed fixtures? And you are missing tolerances. 0.001" is easy. 0.0001" is going to take forever....

    Re: Beginner questions

    It's one of the things that no one tells you, but fixturing can be one of the most complicated problems to solve.

    Using a drilled hole to probe for the x-y on op 2 is a very common technique. ...

    Re: CNC Router Chip Weld/Pile Up

    Chip welding in aluminum is something that all of us have struggled with from time to time.

    Sounds like something changed and you have to hunt that down.
    1) Number one on my list is the raw...
  11. Re: best size/type bit for milling aluminum on desktop cnc?

    Start off with 1/8" bits. That is all your machine is rigid enough to handle. While you can run 3/16" and 1/4" you simply can't run them in an optimum range.

    A lot of people will say that we...

    Re: PCNC1100 considering a 5" vise

    Thanks for the input everyone. I was really dead set on a Shars 550V 5" vise for $295 but I didn't hear any strong reasons not to go with a 6". The Shars 690V seemed a lot bulkier and I really...

    PCNC1100 considering a 5" vise

    I've had my PCNC 1100 for about a decade now and I've always clamped directly to the bed or used a 3" screwless grinding vise.
    I've hit the point where I really need softjaws so I'm considering a...
