The guard combined sliding doors, a viewing window and chip-discharge openings around a CNC machine.
The customer’s challenge
Coolant escaped the guard, doors jammed and spray obscured the observation window.
Material and fabrication route
1.5 mm Q235 steel; tempered-glass observation window.
Process route: Laser cutting → bending → welding → powder coating → rail assembly → seal inspection.
Manufacturing changes
Revised seals, heavy-duty rails and rollers, window clearing and splash control at the discharge opening addressed the operating problems.
Engineering analysis
The door, viewing window and chip-discharge opening were all potential interruptions in the machine guard. The changes addressed movement and containment together: rails supported repeatable door travel, seals controlled escaping coolant, and window clearing maintained visibility. The door-cycle result should be read as an endurance result for the tested arrangement. It does not replace checking access and guarding requirements for a different machine.
Inspection and project results
The project eliminated observed coolant escape, restored smooth door movement and maintained a clear viewing area.
| Project measurement or production detail | Recorded value |
|---|---|
| Protection test | IP54 |
| Door-cycle test | ≥100,000 cycles |
| Window size | 300 × 200 mm |
| Machine travel | ≥500 mm |
These figures describe the project configuration and production scope above. Dimensional, material and production details are identified separately from performance tests. For a new order, the inspection method and acceptance criteria should be agreed against the released drawings.
Planning a similar OEM component
A useful RFQ for this application should make the following interfaces and acceptance requirements clear:
- Machine travel and service envelope.
- Coolant and chip-discharge paths.
- Door mass, rails and cycle requirement.
- Window visibility and seal interfaces.
Include the current drawing revision, mating-component information, quantities and required delivery sequence. Identifying unresolved requirements at quotation stage helps distinguish fabrication work from the equipment-level checks that the project needs.
