Casting cleanup & weld prep
Fields of Application
Finishing systems for foundries, forges and steel fabrication
Casting and fabrication work demands high material removal rates, durable tooling and reliable power on large, irregular workpieces — from sand casting cleanup to weld preparation and descaling on fabricated structures.
LUPFIGS supplies matched SUHNER flexible-shaft, pneumatic and electric drives with heavy-duty abrasives for casting cleaning, heavy stock removal, weld preparation and descaling in foundry and fabrication environments.
Industry Demands
What foundry and fabrication finishing requires
Every heavy-industry task places different demands on power, durability, access and surface condition before further processing.
Heavy RemovalHigh-power drives and coarse abrasives for rapid stock removal on castings and welds
Casting CleanupEffective removal of sand, scale, flash and riser material from cast surfaces
Weld PreparationGrinding and blending on structural joints before inspection and coating
Continuous DutyFlexible-shaft and pneumatic systems built for long production runs
Process ReliabilityConsistent consumables and tool platforms that keep heavy work moving
Typical Work Areas
Where our systems are used
From casting cleanup to weld prep and descaling, each zone needs a different combination of drive, handpiece and abrasive.
01
Casting Cleaning
Removal of sand, flash and riser material
Heavy grinding and cutting on sand castings, investment castings and forged blanks to remove excess material and prepare surfaces for machining or inspection.
Surface Cleaning
Descaling and cleaning before machining or further fabrication.
Large Castings
Flexible-shaft drives for extended reach on bulky workpieces.
02
Heavy Stock Removal
High-rate grinding on large metal sections
Rapid material removal on weld build-up, oversized sections and rough-machined areas using high-power electric and pneumatic systems.
Weld Build-Up
Coarse grinding to reduce excess weld metal before blending.
Section Reduction
Heavy cut on plate, beam and structural fabrications.
Power Platforms
ROTOmax and LSE/LSE grinders for sustained heavy work.
03
Weld Preparation
Grinding and blending on fabricated joints
Preparation of weld seams, root passes and structural joints on steel fabrications before NDT, coating or final assembly.
Seam Grinding
Reduction and fairing of MIG, TIG and submerged-arc welds.
Root Access
Grinders and mounted points for confined weld zones.
Inspection Prep
Clean surfaces ready for visual and ultrasonic inspection.
04
Descaling & Finish
Scale removal and surface refinement
Descaling of hot-rolled and heat-treated surfaces, followed by blending and finish grinding before coating or shipment.
Scale Removal
Coarse abrasives for mill scale, heat tint and oxidation.
Surface Blending
Transition from heavy cut to acceptable finish condition.
Large Components
Flexible-shaft systems for turbines, castings and heavy fabrications.

Application Approach
Build a controlled foundry and fabrication process
We help teams define a clear sequence from casting or weld assessment through to inspection-ready finish.
01
Assess the Workpiece
Identify casting type, weld condition, scale and required surface outcome.
02
Match Power
Select flexible-shaft, pneumatic or electric drives for the removal rate needed.
03
Control Removal
Use the right abrasive and pressure to avoid gouging or excessive heat.
04
Refine Finish
Blend, clean and prepare surfaces for machining, coating or inspection.
05
Validate & Support
Confirm the method, train operators and keep consumables consistent.
