Very high grinding allowances, and at the same time, superior surface finsih requirements on the components; Although easy to describe, what is challenging in this application is the ability to maintain form, size and finish produced by the wheels while removing very high amount of stock
CUMI offers Creep-feed grinding wheels which are designed to perform well in high material removal operations without compromise on the form and finish, Be it continous dressing or conventional intermediate dressing when it comes to creep-feed grinding, CUMI wheels achieve reduced dressing by superior form holding while removing material at high feed rates.
