Thank you guys for replies...I am new at this but would like to build my own cnc machine [ I like building stuff], my main consideration is doing some parts with small dimensions like 5inch x10inch in a 2inch thick plates , and say about 3 feet x 1 foot x max of 1foot [billet engine head]. these are just some projects I am working on own. most of the work is in aluminium and may be steel / iron some times.
I can spend about $900 to $1000 on the parts for the machine. It would be helpful to know what type of cnc should I bulid for this type of work and some spec like power of the motor ,max rpm for the same, Should I go in for servo or stepper motors.what should be the ratings for these control motors.
Also if I need to bulid something different for gear cutting what should I build, specs for that. Gears will be of the size found in cars and light pickups. I have no idea about this, I have a friend who helps me with the design part [he is a mechanical engineer]. |
