With 20 years of research and testing, we ensure the quality of our products. A wealth of trial experience guarantees the advantages of our products. Our steel rail grinding wheels are made from zirconia and resin powder as raw materials, with the use of zirconia significantly enhancing the wear and cutting performance. We strictly control the mixing, hot pressing, and balance testing processes, and further stabilize the product quality through the addition of glass fiber winding, secondary curing, rotary testing, and oven treatment.
