What CNC system is good for CNC boring machine?

FANUC and Siemens are widely used now. Others include Mitsubishi, Heidenham, Fage, and domestic Huazhong CNC. I suggest you consider FANUC and Siemens. The user groups of these two systems are very large.

FANUC operation is relatively simple and easy to learn, mainly engaged in mid-range CNC systems, but also high-grade, high-grade will not be sold to China, there is a blockade.

Siemens' system is a bit troublesome to operate, and so is getting used to it. Mainly engaged in high-end numerical control system, sold to China is at best mid-range.

Personally, I prefer FANUC. Almost all the students trained by China Technical School are FANUC people.
