From automotive metal castings to architectural hardware and complex moulds forged under pressure, every step demands abrasive tools that deliver precision, speed, and durability. CUMI’s foundry and forging abrasive solutions are crafted to handle aggressive riser removal, microstructural analysis, and precision grinding—ensuring defect-free surfaces and production-ready components across foundry and forging processes.
DC wheel, Resinoid, Belt
Rapid material removal from cast or forged components to meet dimensional and surface specs — ideal for shaping large parts and removing excess bulk.
Product Options:
Removes unwanted burrs from cast or forged edges for precision fitment and safer handling in downstream operations.
Product Options:
Precisely cuts and smooths leftover feeder channels in castings, ensuring clean part separation without damaging the component.
Product Options:
Custom abrasives for complex castings and forged parts.
High-strength bonds withstand shock, heat, and impact.
Reduced wear and downtime in aggressive operations.
Every wheel is speed-tested and meets global safety benchmarks
Breakage often results from improper RPM, misalignment, thermal stress, or sudden side pressure. Always choose reinforced, safety-rated tools, inspect before use, and maintain proper mounting and feed control. Use CUMI’s reinforced cut-off wheels for added safety and longer life.
Check for cracks with a “ring test” before mounting, verify that the RPM on your grinder does not exceed the wheel’s rated speed, and ensure the wheel is within its expiry date. CUMI grinding wheels come with clear labeling and traceability to simplify these checks.
Wheel breakage usually comes from improper mounting, running the wheel at speeds above its rated RPM, or applying excessive side pressure. At CUMI, all grinding wheels are speed-tested and safety-certified, but operators should always use proper flanges, guards, and follow mounting instructions.
Yes. Use ceramic grain or superabrasive wheels for high-density iron or alloy castings.They grip harder materials while resisting heat and wear longer.
Replace discs or tools once cut rate drops significantly or geometry is distorted—typically every few hours in continuous operations. Monitor edge sharpness and shape retention to decide timely replacement.
Poor wheel balance and high tool load contribute to vibration. Choose CUMI Resin-Bonded Wheels with precision balancing and low-vibration formulations for smoother, longer grinding sessions.
Variations in grit quality or bonding integrity.
CUMI ensures batch-controlled foundry forging abrasives with tight tolerances and consistent grain distribution, reducing rework and scrap.
