Portable machining
Field Machining
In-place machining for embedded components, sole plates, bearings, discharge rings, stay rings, head covers, bottom rings, and shaft-related components. HRS supports line boring, facing, drilling, tapping, fit restoration, and custom machining when components cannot practically leave the site.
For hydro plant teams
Where this fits.
For outage planners and maintenance managers who need precision machining performed where the component sits, without losing schedule to removal and transport.
Failure modes
- Worn bores, fits, seats, and mating surfaces
- Damaged flanges or faces discovered during disassembly
- Alignment or fit-up problems that block reassembly
- Components too large or schedule-critical to send out
Field methods
- Portable milling, facing, boring, and turning setups
- Pre-machining measurements and setup verification
- In-process dimensional checks
- Final fit and documentation data
Documentation
- Setup photos and dimensional records
- As-found and final measurement data
- Machining summary tied to the repair scope
- Exceptions and recommendations for future work
Call HRS when
- Stay Ring flange is out of tolerance
- A large component cannot leave the plant on the outage schedule
- Owner acceptance depends on clear dimensional evidence
- A repair needs machining and welding coordinated by one field team
