CNC Machine Repair & Upgrades
Save Your CNC. Save Your Bottom Line.
Your CNC machines are the backbone of your operation. When a controller fails, a drive shorts out, or a system grinds to a halt, everything else falls behind schedule—and the costs add up fast.
Replacing a CNC controller or full system can cost upwards of $50,000 or more—and that’s before factoring in the lead time, installation delays, and lost productivity.
But here’s the good news:
In most cases, you don’t have to replace your CNC. You just need the right team to repair, upgrade, and optimize it.
At Altech Process and Control, we specialize in extending the life of CNC machines through expert repair, retrofitting, and preventative maintenance. We help you avoid unnecessary replacements, cut costs dramatically, and keep your operations running at full speed.
When others tell you to replace your system, we find a better way.


What We Repair, Replace, and Upgrade:
CNC controllers (all major brands)
Servo and spindle drives
Operator interfaces and HMI screens
Motion control systems
PLC-integrated CNC platforms
Feedback systems (encoders, resolvers)
Whether your machine is new, aging, or considered “obsolete” by the OEM, we can often repair or retrofit the system for a fraction of the replacement cost—and in a fraction of the time.
