The iron is fine.It is the controls that aged

The survey comes first: geometry, backlash, spindle and screw condition are checked before anything is quoted, and if the iron is not worth retrofitting we will say so. Where it is, the control is designed around that machine — controller, drives and motors sized to it, schematics and an I/O list issued before anything is ordered. The panel is built and tested in our own works, so the machine is out of production for the installation rather than for the whole job.

• Survey and feasibility before a price, including the honest answer
• Controller, drives and motors sized to the machine, not to a catalogue
• Panel manufactured and tested in our works before it reaches your floor
• Axes aligned, tuned and backlash compensated on installation
• Accuracy verified against test cuts at handover
• Operators and maintenance trained on the control they now have

One failed board can idle an obsolete machine for weeks, because the part no longer exists. A current control platform puts spares back on a shelf and support back on a phone line. We fit the control to suit the work the machine does and the people who run it — a turning centre that makes the same part all day and a toolroom mill do not want the same interface.

• Obsolete and unsupported controls replaced with current platforms
• NC-to-CNC conversion where the machine never had a CNC to begin with
• Operator panel and HMI chosen for the work, not the datasheet
• Machine I/O, limits and interlocks rebuilt rather than patched through
• Parameters, PLC program and backups handed over with the machine

A servo axis is a drive, a motor, a feedback device and a mechanical load that have to agree with each other. Swapping one for the nearest equivalent and leaving the loop at its defaults is how a machine comes back with a following error or a finish nobody accepts. We size the replacement against the axis as it is — inertia, duty, travel — then tune it on the machine and prove it on a cut.

• Drive and motor sized against the real axis inertia and duty
• Encoder and position feedback replaced and re-referenced
• Spindle drives and VFDs, including orientation and rigid tapping
• Loops tuned on the machine rather than left at factory defaults
• Brake, limit and overtravel circuits proven before handover

Four different problems arrive as the same phone call. Sometimes the part is current and simply needs buying. Sometimes the failed unit is worth repairing and returning. Sometimes the machine cannot wait for either, and an exchange unit goes out while yours comes in. And sometimes the maker stopped supporting the control a decade ago — which is the point at which a retrofit is worth costing against another year of hunting, and we will tell you which way the numbers fall.

• New parts sourced from the maker or an authorised channel
• Failed boards, drives and motors repaired and tested before they go back
• Exchange units from stock where the downtime costs more than the part
• Obsolete parts traced for controls the maker no longer supports
• Tested under power, not just continuity-checked, before dispatch
• Told plainly when a retrofit is cheaper than the next five repairs

A special purpose machine earns its cost by doing one thing faster, more repeatably or more safely than a general machine can. So the design starts from the operation and the rate it has to run at, and works back to the mechanics — not from a standard frame that the job is then bent to fit. Where a standard machine would do, we will say so; that is a cheaper answer and it keeps its resale value. We take the whole package: frame and motions, drives and motors, PLC, HMI, pneumatics and the safety circuit, designed together and commissioned by the people who designed them. It leaves us documented like any other machine, and your maintenance people are trained on it before we go.

• Built around one operation and the cycle time it has to hold
• Sized to the floor space and the material flow around it
• Told when a standard machine would do the job for less
• Mechanical, electrical and control engineering under one scope
• PLC, HMI and safety designed in from the start, not added at the end
• Schematics, I/O list and a spares list at handover
• Your maintenance team trained on the machine before we leave
• Built from components that are current and can be sourced again
