Oil-immersed Diamond Core Drill Machine
Oil immersed diamond drilling machine is a new type of drilling machine which can drill holes in reinforces concrete, masonry, rock, ceramics, and refractory materials tools. It is a applicable to equipment installation, hydropower installation, tunnel and other construction and installation fields. The aluminium parts of the oil immersed machine are processed with high precision, which has good sealing performance for liquid oil and the expansion force of the seal will not leak oil phenomenon. The liquid oil of the oil immersed machine can increase the service like of the high-speed rotating gear by 2-3 times, and there is no noise when the gear is engaged sound. The seal of oil immersed machine has the characteristics of high speed, high temperature, wear resistance and long service life.
