CNC Retrofit

 A CNC retrofit involves replacing the CNC control, servo and spindle motors, drives, electrical components along with the existing wiring on a machine. KRC can conduct a CNC retrofit on any mechanically sound machine with outdated controls.

• Economic alternative to buying a new machine
• Today’s controls are more forgiving of symptoms of mechanical error and with the right CNC control, you can electronically compensate for these errors in a worn machine
• Retrofits can be done at the machine site taking out the need for rigging and transportation cost
• Faster part program cycle times due to more powerful CNC control processors
• Better part finishes through new control options like tool tip programming
• The amount of time the machine is out of commission is drastically less than the delivery for a new machine
• A one-year parts and labor warranty, plus an additional year parts warranty for Siemens and Fanuc retrofits

KRC has made a commitment to dedicate our time to the 2 best controls on the market today giving us expertise on Fanuc & Siemens controls. KRC has met the requirements to provide certified retrofitting to Fanuc & Siemens controls, and proud to announce we are a Siemens Solution Partner & Fanuc Authorized CNC System Integrator.

1. KRC performs an onsite engineering trip to gather data on the machine to prepare for the retrofit and begin the software development
2. The control kit and new electrical cabinet are built at KRC and then shipped to the customer
3. Once KRC gets onsite to begin the actual integration, old wires are pulled and replaced with brand new along with the old control and motors. The new control system is integrated and tested
4. Final machine alignments and laser calibration are performed
5. Finally- KRC provides training on the new control and presents new documentation including:
   
   • Machine Operator Manual
   • Electrical Connection Drawings
   • PMC Ladder Logic Diagram
   • Fanuc control, servo/spindle, I/O manuals

Machines We Retrofit

KRC Machine Tool Solutions specializes in retrofitting CNC machines for a wide range of large-format industrial machines. If your machine is mechanically sound but running on outdated or failing controls, a retrofit can restore and even enhance its full performance potential.

We provide CNC retrofit services for:

• Milling & Routing Machines: 

  • From vertical and horizontal machining centers to large gantry routers, we retrofit milling and routing machines with modern Fanuc and Siemens controls for faster cycle times and improved precision.

• Waterjet Machines:

  • Extend the life of your waterjet cutting machine with an updated CNC control system that improves cut accuracy and simplifies operation.

• Grinding Machines:

  • Our CNC control retrofits for grinding machines reduce manual adjustments and improve surface finish quality — giving your equipment a new level of consistency and reliability.

• Turning Machines:

  • Breathe new life into aging lathes and turning centers with a modern CNC retrofit that improves part accuracy, reduces downtime, and supports today's advanced programming capabilities.

The best candidates for a CNC retrofit with KRC are large-format machines that are mechanically sound but running on outdated or failing controls, typically with a replacement value of $500,000–$600,000 or more. If sourcing parts for your current control has become difficult, or unplanned downtime is affecting productivity, a retrofit is often the fastest and most cost-effective path forward, eliminating the long lead times and high cost of purchasing a new machine. Not sure if your machine qualifies? KRC performs an on-site engineering evaluation to assess your equipment before any commitment is made.
