CNC Machine Retrofitting, Re-engineering and Module Repair

Give an older machine a reliable future. We re-engineer, rebuild and retrofit CNC machines, integrate controls, build control panels and repair NC/CNC modules for machine shops in Chennai and across India.

CNC machine retrofit and control work

What we do

Retrofit and Repair Services

Retrofitting & rebuilding

Replace obsolete controls, drives and motors while keeping a sound machine structure. Experience with Siemens, Fanuc, Mitsubishi and Heidenhain machines.

Controls & software integration

Software integration for Siemens and Heidenhain controls, and bespoke NC/CNC controls for special machines.

Control panels

Custom control panels and VFD panels, wired and tested to your specification.

Module repair & maintenance

Repair of NC/CNC modules and maintenance support, backed by our spares stock and exchange programme.

When Does a Retrofit Make Sense?

A retrofit is worth considering when the mechanical machine is still sound but the electronics are holding it back:

  • Spares for the control, drives or motors are obsolete or very slow to source.
  • Breakdowns are frequent and each one stops production for days.
  • The control cannot run the programs, communication or features you now need.
  • Energy use, accuracy or cycle time no longer match newer machines.

If the bed, slides and spindle are worn, a mechanical rebuild may be needed as well. We assess both before recommending a route.

How a Retrofit Project Runs

  1. Survey: we record the machine, control, drives, motors, I/O and the faults you see.
  2. Proposal: options for the control, drives, motors and panel, with what is replaced and what is kept.
  3. Build: panels are wired and checked before installation to reduce downtime.
  4. Install and commission: axes, spindle and machine functions are set up and tested.
  5. Handover: documentation, backups and support for the new system.

Repair or Replace?

A single failed module does not always mean a retrofit. For many drives, power supplies, boards and displays, repair or an exchange unit is faster and cheaper. Send the part number and fault and we will tell you which options exist.

Your next step

Discuss your machine

Send the machine make and model, the control, and what is going wrong. Photos of the panel help.

Buyer questions

Frequently Asked Questions

Which machines can you retrofit?

Our past work includes re-engineering, rebuilding and retrofitting used Siemens, Fanuc, Mitsubishi and Heidenhain machines. Send the machine make, model and control so we can confirm what is possible for your machine.

How long does a retrofit take?

It depends on the machine and the scope. Building and testing the control panel before the machine is stopped keeps downtime to a minimum. The proposal states the expected schedule.

Can you repair a module instead of replacing it?

Often, yes. Module repair of NC and CNC equipment is part of our work. Where repair is not practical, we offer reconditioned or exchange units.

Do you build control panels to our drawings?

Yes. We build custom control panels and VFD panels to your specification or drawings, or we can design the panel from your requirement.

What should I send to get a retrofit proposal?

The machine make, model and year, the control and drive models, photos of the electrical cabinet and nameplates, a description of the faults, and what you want the machine to do after the retrofit.

From requirement to quotation

Have a part number or a machine down?

Send the model, nameplate photo or a short description. We check availability, compatible alternatives and lead time, then reply with a quotation.
