Fields of Application
Finishing systems for power generation plant and turbines
Turbine overhaul, casting rework and plant maintenance involve heavy stock removal, descaling and polish on large components — often with limited access inside running plant.
LUPFIGS supplies matched SUHNER ROTOmax and ROTAR flexible-shaft systems, heavy abrasives and continuous-duty drives for turbine work and large castings — helping maintenance teams achieve reliable finishes under demanding duty cycles.
Industry Demands
What power plant finishing requires
Every turbine component and plant surface places strict limits on removal rate, duty cycle, access and final condition.
Heavy Stock RemovalHigh-power drives and coarse abrasives for castings, welds and scaled surfaces
Continuous DutyReliable flexible-shaft systems rated for long maintenance shifts
Confined Plant AccessLong-reach handpieces for housings, pipework and enclosed turbine zones
Descaling & CleanupRemove oxide, scale and weld repair without damaging base material
Surface IntegrityControlled polish and blend on high-value turbine and runner surfaces
Typical Work Areas
Where our systems are used
From turbine runners to plant pipework, each task needs heavy-duty drives matched to material, scale and access constraints.
01
Turbine Components
Grinding and polish on turbine parts
Runners, blades, casings and shaft features need controlled removal and surface restoration during overhaul and repair.
Blade Refinement
Surface cleanup and polish on precision turbine airfoils.
Casing Access
Finishing inside housings and around bearing and seal zones.
02
Large Castings
Heavy finishing on cast steel and iron components
Valve bodies, pump casings and structural castings need aggressive grinding to remove foundry scale, defects and weld build-up.
Scale Removal
Coarse abrasives for foundry scale and heat-affected zones.
Defect Repair
Blend welded repairs into surrounding cast surfaces.
Machine Match
Fair ground areas into machined fits and sealing faces.
03
Descaling & Cleanup
Plant maintenance and outage cleanup
Outage work on boiler areas, pipework and structural steel often means removing years of scale, rust and weld overlay.
Scale & Rust
Aggressive removal on pipe, supports and access steel.
Weld Overlay
Grind and blend hard-facing and repair welds on plant components.
Prep for Coating
Surface condition ready for paint, lining or inspection.
04
Confined Plant Access
Flexible-shaft work in restricted spaces
Running plant and tight turbine enclosures need long-reach flexible drives with interchangeable handpieces and abrasives.
ROTOmax / ROTAR
High-power flexible drives for extended maintenance sessions.
Long Handpieces
Reach into housings, manways and narrow plant corridors.
Quick Change
Swap abrasives and heads without losing outage time.
Recommended Systems

Flexible Drive
Flexible Shaft / ROTOmax, ROTAR
High-power flexible drives for turbine and plant maintenance.
Consumables
Abrasives
Coarse to fine abrasives for castings, scale and turbine polish.
Air Tools
Pneumatic Tools
Heavy-duty air grinders for outage and workshop overhaul work.

Application Approach
Build a controlled power plant finishing process
We help maintenance teams define a clear sequence from outage assessment through to validated surface condition.
01
Assess Component
Identify material, damage type, access limits and outage window.
02
Match Power
Select flexible-shaft drive or fixed tool for removal rate and duty.
03
Remove & Descale
Apply coarse abrasives for scale, weld and defect stock removal.
04
Blend & Polish
Progress through grits to restore specified turbine or sealing surfaces.
05
Inspect & Sign Off
Confirm dimensions, surface condition and document for next outage.
