Usually use artificial diamond instead, because of artificial diamond wear resistance, so the table drilling more, watch relatively long life.
But watch gear processed by diamond such hard material, it can only use the steel material as a shaft, watch the smaller book, shaft, the more fine, every day tens of thousands of revolutions completely rely on in drilling trace amounts of oil to reduce wear and tear, once the oil dry, wheel and axle in dry wear and a few years down, the life of this table has arrived.
The latest market dynamics at any time to see, please pay attention to.
