For CNC machine shops

OEE monitoring for CNC machine shops

Spindle-level visibility on the machines you already run — Fanuc, Siemens, Haas, Mazak and the older ones nobody wants to touch.

How do you monitor OEE in a CNC machine shop?

A gateway reads cycle starts, stops, alarms and programme changes from the existing CNC control — no programme rewrite and no new PLC. Coneqt OEE then reports availability, performance, quality and spindle utilisation per machine, with reason-coded downtime that separates setup and programme change from genuine breakdown. Pricing is ₹499–1,499 per machine per month.

What it reads off a CNC

Cycle start, cycle complete and cycle time per part
Spindle run state and utilisation
Programme number and programme change events
Alarm and fault codes from the control
Feed and rapid override where the control exposes it
Part counts, good and reject

Which losses show up first

Setup and first-off

Job-shop floors usually discover that setup, not breakdown, is the largest single loss — and that it varies threefold between operators on the same machine.

Programme change

Time between one programme ending and the next cutting, measured rather than estimated.

Tool change and tool break

Separated from setup, so tooling policy can be argued with numbers.

Unmanned-shift stoppage

A lights-out machine that stopped at 01:20 and sat idle until 06:00 is the most expensive hour in the shop.

What does it cost for 8 machines?

List pricing, nothing else. 8 machines on the Professional tier at ₹999 per machine per month, billed monthly with no lock-in. Gateway hardware, where a site needs it, is quoted separately and confirmed in writing before installation.

Questions

What people in this sector ask first

Does it work with old CNC controls?

Usually yes. Where a control exposes no data channel, we read cycle and state non-intrusively at the machine instead. The asset list gets checked one by one during scoping rather than promised in advance.

Will it interfere with the machine?

No. The gateway sits alongside the control and reads; it is not in the control path and does not modify programmes.

Can it separate setup from breakdown?

Yes — that is what reason-coded downtime is for, and it is included from the Professional tier.
