Advantage
1. The water supply at the back of the main shaft is adopted to prevent the cooling water from entering the bearing and reducer, so as to improve the service life of the equipment. 2. When drilling, the rotary resistance is reduced and the drilling torque is increased. 3. The drilling time is shortened and the production efficiency is improved.
