Abstract
The abrasive property of ML belts is superior to endless belts.In recent years,they are used for grinding a train rail.The train rail grinding machine has developed and the abrasive property has been investigated with the ML belt.The ML belts grinding is superior to the face grinding by grinding wheel at a point of Quantity and efficiency.In this study,the ML belt was improved with the target of more effective grinding.The 3B belt was a kind of the ML belt and was consist of Zirconium abrasive cloth and CBN abrasive cloth.The abrasion experiment using seven kinds of belts including this 3B belt was carried out and the quantity of abrasion was compared.The quantity to grind with the 3B belt which the ratio of Zirconium abrasive cloth and CBN abrasive cloth was 2 to 1 was most of all belts.
