Job shops and component manufacturers live on spindle hours. A CNC lathe or machining centre that stops in the middle of a batch holds up every order queued behind it, and the faults that stop these machines are mostly electrical: a spindle drive alarm, an axis servo that trips under load, an encoder error after a crash, or a control that has lost its parameters when a backup battery ran flat.
Accuracy problems are the slower kind of failure. Ballscrew backlash creeps up, way lubrication stops reaching the slides, the spindle warms more than it used to, and parts drift out of tolerance gradually enough that nobody notices until a batch is rejected. Catching that drift early is mostly a matter of measuring and logging the same few things on a schedule.
01 / Equipment
Machines we work on in cnc & manufacturing plants
- CNC Lathes & Turning Centres

02 / Work
What the work usually involves
- Spindle and axis drive alarm diagnosis
- Servo motor and encoder replacement
- CNC control parameter backup and restore
- Backlash and accuracy checks
- Electrical cabinet heat and wiring clean-up
- Control retrofit on mechanically sound machines
03 / A typical fault
A fault pattern worth knowing
A machine that throws a servo overload alarm only on long, heavy cuts usually has a mechanical cause behind an electrical symptom: a tight ballscrew support bearing, a way-lube shortage or a gib adjusted too hard. The drive is reporting the extra load honestly, and replacing it fixes nothing. Checking the axis load meter at a known feed before and after a mechanical check is what separates the two.

05 / How it works
What happens when you get in touch
- 01Call or WhatsApp us with the machine, the fault code if there is one, and where the plant is.
- 02We match a technician who works on this kind of equipment, and they review the code before setting out.
- 03On site they make it safe, diagnose, and tell you what has failed and what the repair involves before starting.
- 04After the repair they run the machine with you, and you sign off a job card and get a report for your records.
06 / Questions
CNC & Manufacturing: common questions
Can you work on older CNC machines with obsolete controls?+
Yes. Older controls can often be repaired at board level, and where spares have run out, the control can be replaced while the machine's mechanics, tooling and fixtures are kept. Back up the parameters and programs first if the control still boots.
Our parts are drifting out of tolerance. Is that an electrical or a mechanical fault?+
It can be either. Gradual drift over a shift points to heat growth; sudden steps point to a lost reference or encoder problem; drift that grows over months points to backlash or ballscrew wear. Measuring backlash and comparing it with earlier readings is usually the first check.
How do we get a technician for a breakdown in a cnc & manufacturing plant?+
Send the machine, the fault code or symptom and the plant location by WhatsApp or phone. We match a technician who works on that equipment and tell you who is available and when before you confirm.
Can we set up scheduled maintenance instead of calling for breakdowns?+
Yes. A planned maintenance schedule covers the machines you choose, with visit frequency set by how much each machine's failure costs you.
What happens if parts are needed during a repair?+
The technician lists the parts needed and the sourcing options before anything is fitted. Parts are quoted separately from labour.
