    Spindle Speed in Dead Zone

    I'm all new to this so I'm just using the program as a starting point. I don't mind experimenting. What I'm asking is what should I look out for that will tell me I'm doing something wrong?

    Spindle Speed in Dead Zone

    I apologize for learning out load - the more I play with this calculator the more it seems to be varying everything else to keep the cutting force and chip thickness constant. Is that right? does that mean I can use any value that makes the specified chip?

    Spindle Speed in Dead Zone

    This is where I'm totally ignorant. The calculator lets me vary the spindle speed. If I start with 3" width it recommends 582rpm and 16in/min. If I manually increase spindle speed to 1000rpm the calculator says to feed at 27in/min. that seems like a high feed rate to me but I honestly don't...

    Spindle Speed in Dead Zone

    I figured it wouldn't be that simple. I'm cutting mild steel with indexed facemills. The worst seems to be an ISCAR FS45ST3.0 with with SEKT43-AF-R inserts. The calculator recommends 582 rpm/16in/min at 3" width and .03" DOC. This is supposed to take 1.16hp. In high range my 3hp motor...

    Spindle Speed in Dead Zone

    Hi, I have an Acer 3VS mill with a digital head. I'm new to milling and have been using FSWizard for calculating speeds and feeds. My mill runs 0-450 rpm in low range and is advertised at 0-4500 in high. My problem is that some of my face mills call for using 600-650 rpm and at that speed...

    Burke / Powermatic Horizontal and Vertical Milling machine with Rusnok model 70 head

    1979 USA Burke mill in excellent condition with all original factory options and a Rusnok 70 head. It's small but was perfect for me when I was limited in space. Comes with the original factory vertical milling attachment and all the original horizontal milling parts including spare arbors and...

    Advice on insert style mill cutters

    That's the plan - 45 degree cutter that takes SEKN inserts. I've been poking around. So far I've seen Shars and the cheapo ebay in that configuration. Still looking.

    Advice on insert style mill cutters

    I was just playing with a 3 insert 45 degree cutter that I has in a drawer. It uses TPU 322 inserts and it worked when facing mild steel tube but the result wasn't what I hoped for. You said the TPU style wasn't good for milling - can you recommend a 45 degree insert that's common and works well?

    Advice on insert style mill cutters

    Ahhhh...thanks! For now I'm looking to face off flat surfaces. So a 45 degree cutter that uses the APKT style inserts? I'm starting to see that there are a lot of different APKT inserts so like you said, I may not get the interchangeability even within that style.

    Advice on insert style mill cutters

    I honestly don't know the difference between the 45s and the 90s. Is it that the 90 is stronger and will cut deeper? Most of what I do is mild steel or stainless I appreciate the links, I've been roving ebay but would like to develop more reliable suppliers.

    Advice on insert style mill cutters

    I was hoping to avoid the learning curve I went through with lathe inserts but this looks much the same. I found a reference for the APKT inserts. They look good - cheap and available. Any recommends on a source for reasonably priced cutters?

    Advice on insert style mill cutters

    I've been working with a mini-mill for years and finally bought a full size knee mill. Now that I have the ability to use larger cutters I'm moving toward the type that use carbide inserts. How can I maximize interchangeability? My first thought is to limit the number of shapes, pick a common...

    Anyone familiar with Moore toll and equipment?

    Hi, I'm considering a new Acer knee mill. Best price I can find is through Moore tool in Goodyear AZ. If anybody has dealt with them I'd like to know how you're experience was. Thanks!

    WTB Manual Mill in Southern VA

    That's what I'm seeing. PA, NY, NJ are full of machinery but nothing close. By the time I get to Charlotte and back I've got a long day invested just to look.

    WTB Manual Mill in Southern VA

    I've been looking for a decent vertical mill but not much available where I live (southern Virginia). I'm willing to pay a fair price that depends on quality, features and tooling. I need something that's ready to cut chips not a project. If anyone has one please contact me.

    Advice on TRAK TRM Mill

    This was my main concern. I like the idea of "extra" features just in case I want to CNC but the complexity comes at a cost. Do you find manual operation any more cumbersome than it would be on on a BP clone?

    Advice on TRAK TRM Mill

    Hi, I've been looking for a knee mill for some time now. Not much local and what I do see usually needs some "easy fix". My use is hobby machining and making parts around the farm. I can use a manual machine but have no experience with CNC. My original thought was a Bridgeport or clone...

    Help getting Powermatic 87 back in service

    SMT, I understand your concerns. I'm 62 and been working with my hands since early teens. I have a lot of good stories but have managed to get through with all the pieces attached. I'm a lot slower and more deliberate these days. I'm leaning toward a block or file just because there isn't...

    Help getting Powermatic 87 back in service

    Stephen, My best guess is that this was used somewhere that had a machine shop. The transmission case has been repaired and the final drive bearing replaced. It looks like they turned the wheel shaft and added a bushing. That's the copper colored pipe in the picture. I think the wheel turns...
