*This label is your assurance that the product has passed rigorous internal testing and meets CUMI highest quality and safety expectations.
Each CUMI grinding wheel that passes the CXS process will be labelled with this.
Every year, many accidents happen due to the use of abrasive products and grinding tools, especially when customers choose low-quality, cheap options that put their safety at risk. To keep users safe, CUMI is committed to making high-quality abrasive products using strict quality control measures. All our products are manufactured and tested according to approved safety standards, as well as CUMI’s own internal safety standards, which include tolerances up to 75% tighter than the EN standards to ensure superior safety and reliability.
CUMI’s internal safety standards are designed to provide extra protection for users by going beyond industry requirements to ensure safety and trust. These standards ensure consistent product quality, they also reflect our real-world experience and understanding of customer needs. Most importantly, it demonstrates CUMI’s strong commitment to safety and reliability. By following safety and testing standards, we make sure our abrasive products are not just good, but among the safest and most reliable available in the market.
Weight, Outer Dia, Inner Dia to ensure the Density of the wheel. Young’s Modulus (YM) value: It’s verified with the defined set of values to ensure there exists no cracks inside the wheels. Metal detector is used to ensure that all the Wheels have a ring inside which is kept during the molding process
This test measures the lateral deviation or wobble on the grinding wheel’s side surface during rotation, ensuring stability and precision in operation. CUMI maintains a tolerance that is 75% tighter than the standard specification, ensuring significantly reduced side-to-side movement for improved performance and safety.
Each grinding wheel undergoes individual inspection to ensure proper balance and performance. CUMI applies tighter diameter tolerances than EN standards. These stricter controls help guarantee well-balanced wheels, promoting uniform grinding performance and consistent wear characteristics.
This test measures irregularities on the outer circumference of the grinding wheel to ensure smooth and even rotation during operation. By detecting any unevenness, it helps maintain consistent performance and reduces vibration for safer, more precise grinding.
The Ring Test needs to be carried out with a light, non-metallic implement material on the Wheel at periphery and 45 degrees to either side of the wheel’s vertical centerline and ensure it gives a clear bell sound to ensure that the wheel has no cracks on it.
The wheel is made to run at a speed of 1.5 times the specified RPM to verify whether the wheel could be able to withstand the rotation.
Determines the wheel’s resistance to wear and load, helping select the right wheel for specific materials and for right application.
To test at what speed the wheel bursts while speed goes on increasing, this will clearly show the strength & Durability of wheel during abuse also.
Identifies ferrous contamination in the wheel, which can impact non-ferrous grinding and lead to sparking.
CUMI operates with a thickness tolerance that is 30% tighter than the EN standard specification.
Ensures the grinding wheel maintains its designed contour and edge shape for precise applications.
Abrasive products improperly used can be hazardous.
Be aware of the hazards likely during the use of abrasive products and observe the recommended precautions to be taken:
At Carborundum Universal Limited (CUMI), we pledge our commitment to all our stakeholders by consistently delivering products and services of the highest quality, safety, and reliability.
Through our robust CUMI Quality Management System (CQMS), we align with globally recognized standard benchmarks such as EN 12413, EN 13743, IS 715, oSa standards, and ISO 9001:2015, but we also go beyond them. With the integration of Total Productive Maintenance (TPM) and our own internally developed CUMI Excellence Standard, we uphold performance criteria that are significantly more stringent than industry norms.
This pledge reflects our ongoing commitment to excellence, innovation, and integrity — making sure every CUMI product stands for trust, precision, and safety.
