This paper describes a grinding technology with minimum coolant, that is ECOLOG grinding. This grinding system is a process using a slight small amount of coolant and a little oil mist. We hope that the process is effective for costs saving regarding coolant, energy saving, cleaner environment of production line. We applied this process in the grinding processing that used CBN wheel, and examined the grinding ability. At first we performed processing test with material removal rate Z'=7 and found that ECOLOG grinding had same grinding ability as that of coolant grinding. In order to aim at improvement of material removal rate, we increased wheel peripheral speed from 80m/s to 120m/s and performed processing test and found that maximum material removal rate improved from Z'=7 to Z'=9 without decrease of hardness of workpiece after processing.
