emco pc mill 50 & similar

[hutchison]

hello all, my first post here. I'm a u.k based machinist and just picked up a few bench top machines. One is the emco pc mill 50, i'd like to start a small thread for any that wants to add information regarding these machines or similar wether good / no good, faults and remedies, programming tips even.
im not experienced in cnc programming and have been a manual toolmaker for 11 years now, this is the first step on the ladder to learning the art of cnc.

with this particular machine i have the use of two different control systems, the emco wincam cad/cam/nc software and also an emulated Ge Fanuc 0 type control which is emulated accurately via the emco Pc program 'winNc'' and controlled via keyboard input so i have the choice of both which will be handy im sure. i have a working area of 190X , 90Y and 190Z, and program controlled spindle speeds of upto 2500rpm. feedrate max of 750mm/min. i appreciate its not a multi-pallet mitsubishi with 2sec cTc !.. but its mine and i'm happy with the chance to get going. i'd also like to learn of other similar machines like the home built cnc's so a better gauge of capability can be had you know i might be better off outing it and getting another set-up etc.

ive noted allready a few things which are going to be a small issue to overcome. these are the toolholders which are from what i can understand not freely available in the tooling world MT30 spindle taper i think (will check). i do have 4 of them so i can tool up for small jobs etc, but at the moment they are all esx-25 type collet holders.. now im sure this is the same as ER25 so ive just ordered a set of er's' in the hope they fit. with regards to holding other tools like face mills or morse taper shanks i guess i'm stuck.

heres a picture of the machine installed in my workshop i'm tooling it up slowly to get ready for some cutting what experience have you of these?

Hi I have the same machine in my workshop/basement.

I think its a wonderfull machine to work with. Its not the quickest but forr me its sufficient.

I only have an ancient version of winnc so if i could have a copy of your software I'll be happy as a baby hahah


Good luck in hobbying with your emco.

Best regards

Hi

I have the same machine and i think ts great, maybe not the fastest butr its working for me.

I myself have 8 tool holders and a holder for a side rough tool.
The ER-25 collets work fine in the emco tool holders.

If you need some more holders try and search for SK-30 holders and make a couple of Ball-tips with your lathe on top of the holders. That should work.

Personally I have an ancient version of winnc so If I could get a copy of you Ill be happy as a baby.


Good luck with your emco,

I hope it will bring you as much pleasure as it has me.


Best regards

Binski

Hi Hutchison and welcome to the zone

I have neither of those machines so wont be much use there but will keep an eye on your thread and if you have any questions I may be able to help you with will jump in.

Good luck,
John

hello and welcome
i also have niether of these machines
as for tooling post up dims in your collets/holders and i'll see what i've got that might be suitable

I have an Emco PC Mill 30 and it still works great even though it programs in DOS. I plan to rip out the control system and add a new driver so I can use MACH 3.

I picked up an Emco F1 CNC and plan to change it over to a Mach3 controller. I am trying to determine what stepper (or servo) motors to switch over to if I ditch the factory ones. I do not know their condition yet.

I can post as I make progress - perhaps there may be some overlapping interests.

I have found a few www links that have Emco manuals (main, pics, etc.) I can post those too if interested. I was looking for F1 info but there may be others.

Good luck with the project!

thanks for the support, i was beginning to think i was on a small island

mike, i have found the standard er25 collets to fit the emco 'mt30' holders, which themselves are apparently the same as sk30 but with a pull stud which im sure i can knock up on lathe, i will hopefully buy some sk30's soon if anyone has any? do they have a thread up the back end? and what new tool holding possibilties do they bring?. for now I'm limited to the ER collet sizes of which is 1-16.

I picked up a nice 0-10 with jt2 (jacobs taper) twist grip chuck and had them make me up a 16mm straight shank to jt2 adaptor for use on the mill, not a bad price all in around £44 that included the jacobs manufacture of the adaptor, its not a rohm but for the price i was happy. i also picked one up for the lathe 0-8 twist jacobs ball bearing again, and jt1 fitment so a jt1 to morse taper 1 adaptor was had off the shelf at J&L.


one thing id like to add to this mill is constant suds, at the moment it does not have any and was not manufactured with the provision!, only a spray mist type coolant option was available that isn't really any good except on cold headers in my experience, has anyone applied a system succesfully / spray mist even..how does it perform with steel/alluminium? what type of pump i.e; what pressure does it want to run, i was toying with a 12v fish tank pump & transformer power supply type set-up...

please go right ahead with the links and would like to hear more about that project for sure. so whats the differences to using mach3 and say the normal emco cad/cam software?.. at the moment i'm illiterate with cam systems although i've a few years use on 3d software like solidworks etc. is the mach 3d programming capable?. i've thought about licom alpha cam control etc, as a post processor is available for the 50 .. i got as far as the price!.

These links are simply from some Google searching - but they may help others. There are some manuals (programming and maintenance), pics, etc among the sites:

http://www.smoregrava.net/cncdownloads.htm
http://www.kb1.ca/2007/06/emco-f1-cn...on-manual.html

I am looking at the Mach3 controller conversion because I do not have the Emco controller. I am by no standard an expert (perhaps not even marginally informed!) on CNC, yet I have managed to mostly convince myself the Mach3 approach is the route I will take.

The Mach3 is the controller replacement. For generating the G code I will use another piece of software that I have yet to identify.

Motor drivers, etc are also in the plan.

I'll let you know how it goes.

good information in there for the F1.

here is a user manual for the wincam software, pretty pointless as if you have the software it will allready have this built in as the help file!, never the less:

Wow,
I just found you guys. I have been researching for the local High School whether it is possible to upgrade their PC Mill 50 and their Emco Compact 5 CNC Lathe. Both appear to work as delivered 15 years ago. The Mill appears to be the better candidate since it is PC based. So far I have found a dedicated interface card in an old PC that appears to exchange data with the Mills controller using a serial interface. I use Mach 3 at home (on my Taig Mill) and was hoping to be able to use it at school since its user interface is very graphical as well as instructional. Unfortunately Mach does not use a serial interface.
Sorry for the rambling. I guess what I would be interested in finding is what upgrades (software/computer) folks use that is easier and more modern than what was delivered with the system 15 years ago.

thanks in advance Rik
