I've never heard of the "conception cnc machine", and I doubt very many of us here have either. Can you provide a link to what you're talking about? By "engine", do you mean the motors that drive the axes, the spindle, or something else?

[Rita lay]

thank you for your answer, i meant by engine: motors that drives the axes

[awerby]

Okay, but what are you driving? You need to match the axis motors to the machine they are supposed to move, but we have no idea what your "conception" is or what you're planning to do with it.

I think the answer is 42 ,..

hey Rita.
what kind of problems you are facing?
Can you explain here perhaps somebody helps you.

For the Axes, i recommend yaskawa, KEB or Siboni. For the Spindle Giordano Colombo, Hiteco or HSD.

I think rita is from a country that far from English..
dictionaries suggesting the plan and concept in same meaning..

cars has engine, but in many language used the motor word..


rita

what you are going to mill ?
wood? plastic?

I think you are planning a router..

go to alibaba dot com and you can find drives and motors..

if machine 1.25 meter x 2.5 meter then look for nema34

steppers are working good for this purpose..

================================================== ===================
these are for a larger router

Nema34 CNC controller kit - Shop Cheap Nema34 CNC controller kit from China Nema34 CNC controller kit Suppliers at Changzhou Rattm Motor Co., Ltd. on Aliexpress.com

and these are for smaller router.. like 50x100 cm work area

Nema23 CNC controller kit - Shop Cheap Nema23 CNC controller kit from China Nema23 CNC controller kit Suppliers at Changzhou Rattm Motor Co., Ltd. on Aliexpress.com




try to choose controller with individual drives, as they are performing better than compact all in one drives..


of course there are many other seller... take your time to find the best nmatching for you..
and don't hesitate to asking...


by the way, what country you are from?

[Service SCM BR]

I nor recommend stepper engine for the axis how X,Y,Z. Stepper engine use only tool changer. For the axes use servomotor with encoder or magnetic tape.
Because it will offer more accuracy in desired measures and minors Tolerancing

Sorry for my english.

true all you wrote.. scm

however folks who just plan to build a cncrouter they might can not spend all their money only on the control..

some control, like scm group build in into their equipment , that cost might more than a good car..

companies who planning production they are don't asking help on cnczone, they have own engineers to figuring the necessary equipment..

again, that is very true you wrote.. a linear encoder """tape"" cost itself more than a whole control..


on a welded structure due to high expanding it just doesn't work really..

another point is, very rare the home router builder who can measure 8 feet within 0.001 tolerance :-) so that extreme precision falling out of the demand..
