How to use the button bit more reasonable
The service life of the button bit is determined by the internal quality of the product, scientific selection and correct use method. Drill bit products are inherently inferior in quality, no matter how they are selected and carefully operated and used, the drilling footage (life) will not be high. On the contrary, no matter how good the quality of the product is, no matter how scientific the choice is, improper methods in the operation and use of the product will also cause the product to fail prematurely and fail to perform to its expected level.
The drill bit product bears great strain stress during rock drilling, so it cannot be reckless. It requires careful operation and use to get the maximum benefit. Drill bit products should reduce the propulsion and impact energy during use, and use a lot of flushing water, otherwise the waterless opening will increase the temperature of the bit. Once the flushing water is turned on, the bit alloy will produce micro-cracks. Unusual failure occurs, and dry drilling will cause the risk of sticking, which will cause the water hole of the drill bit to be blocked. During the use of the drill bit product, the use condition of the drill bit should be observed in time, especially the hard rock, when used for a period of time, it is necessary to judge whether the product needs grinding. The method can be judged according to the following conditions:
1. The rock drilling equipment is stable, and the rock drilling speed is significantly reduced by 30%.
2. A worn platform appears on the alloy teeth, and the platform diameter has reached 1/3-1/2 of the tooth diameter.
3. The alloy teeth appear "snake skin" or cracks.
When the product appears one of the above three, it indicates that the drill bit needs to be ground, otherwise the drilling efficiency will be reduced, the reaction force of the rock will increase, and the stress can be increased by 50-100%, which will not only cause alloy fracture, but also cause the drill bit body Even the damage of other supporting drilling tools accelerates the wear of rock drilling equipment. The column tooth bit is regularly ground to restore its original shape, which helps prevent alloy teeth from chipping, reduces the cost of rock drilling, increases the service life of the bit, and maximizes the performance of the product
