    Setup and tooling advice for newby

    My point is (in your example) that if I could find those covers modified by someone else who specializes in that 'style' of work for $2, I can sell them to the customer for the standard $2.25 price (or even less) then I'm still making money doing essentially no work. I can instead spend that...

    Setup and tooling advice for newby

    Something worth learning is how to get your customers parts efficiently. In some cases that may mean you don't actually cut anything... Why is he getting parts 90% done and adding one hole? Why not have them mill everything. Or better yet why not get them laser cut complete? A fiber laser will...

    Need a suggestion for large part workholding

    If you can use the existing op 1 fixture and some existing long tools to cut clamping features or bore bolt holes like Trevor360 mentioned that's going to be more efficient, in this case with low volumes and high margins that probably makes sense to buy tools if they didn't have them. Just...

    Need a suggestion for large part workholding

    Could you use a dovetail bit in a hand router to mimick Marcus' idea and give you a positive locking feature without any pre-op machining or oddball tools? Router and bit from horror freight probably cost <$50 if you don't have anything on hand... I've seen a shop that runs all their blanks...

    Ganty HMC recommendations please

    At a previous shop we had a pair of 100'*20' articulating head 5 axis mills. The building was constructed around the machines. Accuracy in the envelope was as poor as 1/8" because the building would shrink and grow over time. Rails had trouble staying flat and straight. The heads also had their...

    Lathe slug stick out

    As mentioned before this lathe is small, like really small...95mm 3 jaw chuck or a 5c collet. I really like the idea of using versa grips and may try that in the future, but I don't have any soft jaws for the chuck right now. I used to have access to a fiber laser and I think even with the...

    Lathe slug stick out

    Marcus, good point about the parting vs. saw cutting. I had a bigger lathe but got these because small lathes would be perfect for the little widgets I usually need but typical now that I have small lathes I've got some bigger parts... Hahn, I kind of generalized the shape of the parts, the...

    Lathe slug stick out

    I do have a little 95mm Rohm 3 jaw but the drawbar for the collet chuck on the machine I'd like to do this on is kinda stuck so I was hoping to avoid changing that out... What kind of clamp:stickout ratio is advisable for that kind of setup? And some kind of reduction in spindle speed as well?

    Lathe slug stick out

    I have a batch of 6061 parts to make that I have always done on my mill despite being obvious lathe parts. I finally managed to get my Emco 220P lathes running and would like to turn them loose on this job. Problem is these lathes have a 1" bore, and these parts are made from 2" bar... There...

    Modular Fixturing for one-off prototype parts

    Moreside M200? Very tempted to try one, would be perfect for indexing jobbies https://moresidefixture.com/model-200

    Emco 220P Lathes

    Somehow I have about 15 manuals for these two machines, but there just doesn't appear to be much about the process of setting up offsets in any of them. I would expect to drive a tool up to the spindle face and measure the tool Z, or touch off the side of a part to set tool X. I just can't seem...

    Emco 220P Lathes

    I included the controller models. One is Emco TM1 and one is a TM2. The particular lathe models are 220P, just different years. I have manuals but they don't really explain how to set offsets, they just say how you use them in programming. I was told they program similar to Fanuc but the...

    Damaged BT30 spindle. grrr

    I've only had one pull stud break on my Brother and it was a Maritool as well. 3/8 endmill taking light passes in steel, though I never checked them for signs of wear. Will definitely be paying more attention to them in the future. For high production shops do they routinely replace studs...

    Emco 220P Lathes

    Picked up a pair of these from another PM member before he moved out of the country. They were kind of a right place/price purchase to fill some space after I just sold off a larger lathe. More of a side project than mission critical equipment... I've gotten air and power to them, and verified...

    Machining formed (bent) plate

    Tubes are generally .035 to .049" wall. These parts will all get machined down to .049-.065" thick with ribs throughout, hence it being so thick to start so the ribs can be taller/stiffer. Bearing seats are fine, using jigs and a methodical weld sequence I can maintain tight enough tolerance...

    Machining formed (bent) plate

    Right, machining tools to make a prototype carbon frame sounds like a much easier solution... Horses for courses. Steel frames are very popular (I've made and ridden lots of them) sometimes designs just don't play well with straight tubes, and sometimes I get an itch to try something different.

    Machining formed (bent) plate

    It's part of a mountain bike bike frame, it has some precision bores for suspension bearings, so the bearings seat has to be right, as does the position. I'm not super picky about where the top ends up, I will grind or fill whatever I need to make it fit to the tube, I'm mostly just wondering...

    Machining formed (bent) plate

    I am designing a welded steel frame that needs to have two parallel plates bow away, and then back towards each other to encompass a component. The plates are approx. 1/4" thk, 2" wide, and 12" tall, the bends are maybe 25* and add about 1" to the overall width of the structure. These brackets...

    Fanuc 0T Tool Setting and Work Shift Help

    That is the Fanuc control panel, the rest if it is the W&S specific control So to call up a tool when I want to set I should use T__00 (ex. T1=T0100, or T12=T1200)? Ang every program should call up a G50 like I use a G54 on a mill? I have just been using the turret fwd/rev buttons after I...
