Guidance & support from CUMI experts to help improve performance and reduce costs.
Built to perform under pressure, across foundries, and fabrication lines.
Fettling is more aggressive—used primarily in foundries to remove flash, fins, and gating material from castings. It demands tougher abrasives with higher cut rates and impact resistance compared to standard surface grinding.
It depends on the metal type and task. For general steel grinding, zirconia and ceramic discs offer durability and speed. Use flap discs for buffing and surface finishing, and fiber discs for aggressive stock removal.
Recommendations:
Check the instructions and specification info regarding substrate types and machine speed. Avoid side pressure, always secure the workpiece, and inspect for damage or imbalance before use. Improper mounting or overfeeding can lead to dangerous breakage. Work at the right position and angle so the blade runs smoothly without uneven force.
Yes. Over time, metal cutting and grinding abrasive bonds can degrade, especially if stored in humid or poorly ventilated conditions. Check for the expiry date, if it is 2 years since its manufactured then try not to use it unless it is inspected thoroughly by the technician. Always check for cracks, warping, or damage before use, and store products in dry, stable environments. CUMI Reinforced and Vitrified Wheels maintain stability over extended periods. Always inspect before use.
Soft metals like aluminum tend to load abrasive surfaces. To counter this, use specially formulated products like CUMI’s non-loading Fibre Discs or resin-bonded abrasives for non-ferrous metals, which resist gumming and offer smoother cuts.
