Hello everybody, it is my first thread!
I am a beginner in CNC world, so excuse me in advance for no technical words

As i told i would like to start with a CNC machine to engrave stainless steel, i am a 3D designer (i know artcam). I have seen many machines from 100$ to >20.000$ my goal is to create a kind of punches to stamp design over brass or alluminum, (i think steel is a good material for that right?), so my job is to create "stamps".

I will not use this machine many times, i will create 2-3 punches/stamps every month. I know there are companies that create custom punch based on the customer design but i would like to learn it myself.
Can anyone help me to find a cnc machine to start my works? If someone want to sell an old machine i am interested in buying it too. but keep in mind it will be my first CNC so i cannot buy machine > 1000$

Thank you so much!
