Nov 03, 2008 What you are describing is a common but obsolete way to express a grade of machining finish. The idea was to represent rough or first machining operation by one triangle (triangle symbolizes the turning cutting tool). Two triangles meaning two passes of the tool and hence finer finish. Normally four triangles require a grinding operation and a roughness of between 32-16 ….elgi ultra wet grinder price in uae Fote Mining Machinery Co
