Steel

Steel processing demands precision, power, and speed. Whether you’re cutting beams, grinding welds, or polishing stainless parts, the quality of the abrasive directly impacts productivity, tool wear, and surface integrity. CUMI stainless steel abrasives are built for heavy-duty performance—supporting fast material removal, consistent finishes, and longer abrasive life across carbon steel, Mild steel, stainless, and speciality alloys.

Stainless Steel Abrasive Applications & Solutions

Cutting​

Precision cutting of bars, sheets, pipes, and profiles in Mild steel, carbon steel, stainless steel, and alloy grades. Designed for minimal burr, low heat zones, and fast feed rates. Compatible with chop saw machines,angle grinders, cutting wheels, and high-speed cutting machines.

Product Options:

  1. Cutting wheels
  2. Reinforced cutting wheels (RFC)
Grinding​

Heavy stock removal on weld seams, castings, and rough surfaces. Suitable for fabrication shops, foundries, and structural steel prep. Abrasives are designed for durability and cool cutting to avoid temper loss.

Product Options:

  1. Grinding wheels
  2. Flap discs
  3. Fibre discs
  4. Depressed centre wheel
Polishing

Fine finishing of stainless steel, appliance parts, and ornamental steelwork. Uniform surface refinement before painting, powder coating, or final assembly. Available for flat panels, curved profiles, and cylindrical parts.

Product Options:

  1. Bore mops
  2. Flap wheels
  3. Spindle mops
Buffing

CUMI’s best steel buffing wheels and compounds deliver swirl-free, mirror-like finishes. Commonly used on stainless steel components, pipes, kitchenware, and railings.

Product Options:

  1. Flap disc
  2. Sheets & Rolls

Why Choose CUMI Abrasives For Stainless Steel Manufacturing

Durability

High grain retention and bonding strength mean longer life and fewer tool changes under high-pressure conditions.

Flexibility

Whether your blades and grinders run carbon steel cutting, weld blending, deburring, or fine finishing, CUMI formats perform seamlessly, without risk of cross-metal glazing or contamination.

Consistent Quality

Our sealed production and strict QC ensure every batch meets grit, bond, and bonding consistency, reducing process variation and rework across high-throughput lines.

Tailored Solutions

Custom grit combinations, disc sizes, and bonds are designed to match specific machines, materials, and finish goals.

FAQ’s On Using Stainless Steel Abrasives

Use a high-performance zirconia or ceramic grain disc for stainless steel and an alumina-based disc for mild steel. CUMI offers both options, with resin-bonded options to control heat.

Non-woven or fine grit flap wheels (e.g., 240–320 grit) prepare the surface without over-smoothing—ideal for better coating adhesion.

It's not recommended. Stainless requires abrasives that resist glazing and contamination. CUMI provides grade-specific products to avoid cross-contamination.

To extend abrasive life in high-volume operations:

  • Choose the right abrasive type based on material hardness and application (e.g., zirconia for stainless, alumina for mild steel)
  • Maintain optimal pressure and speed — excessive force reduces lifespan and affects finish
  • Use proper cooling or dust extraction to prevent heat buildup and clogging
  • Ensure correct storage — moisture and contamination can degrade performance
  • Switch to high-performance steel abrasives with stronger bonding and grain retention, like CUMI’s long-life bonded systems
