CNC Machine Service & Retrofitting for SMEs: 2026 Guide
MST Automation's direct answer: CNC retrofitting upgrades legacy machine tools with modern CNC controllers (Fanuc/Siemens), servomotors, and drives. It reduces cycle times by up to 30% and costs 60% less than buying a new machine. It is the fastest ROI path for SMEs to restore machine precision and integrate with modern CAD/CAM software.
Why Retrofit Instead of Replace?
The mechanical iron of a 20-year-old machine is often superior to modern entry-level cast iron. The component that fails is the obsolete control system. By replacing the outdated electronics, we give the machine another 15 years of productive life.
- Cost Savings: Typically 1/3rd the cost of a comparable new machine.
- Familiar Footprint: Requires no changes to your shop floor layout or existing foundations.
- Modern Capabilities: High-speed machining, rigid tapping, and ethernet DNC capabilities.
Our Retrofitting Process
1. Mechanical Assessment
We test ball screws, linear guides, and spindle runout. If the iron is good, we proceed.
2. Panel Building
A completely new electrical cabinet is manufactured in our facility, completely tested before shipping.
3. Interfacing & Tuning
On-site wiring, PLC ladder development, and servo tuning for optimal surface finish.
