Button bits has higher technology, much longer primary grinding time
and higher drilling efficiency while comparing with taper chisel
bits and taper cross bits, so that the button bit is popular among
the users.
According to the tungsten carbide insert, button bits can be divided
into the types of hemispherical button, conical button and parabolic
button, etc.
Button bits with hemispherical button is for high bearing capacity
and abrasive resistance while conical button and parabolic button
are for high drilling speed and low abrasive resistance.
When drilling, adjust the parameters of impulse and rotary with the
standards of no jamming, high drilling speed and no bend of tapered
drill rods.
Check the rock drill bits after each drilling. If the buttons are
seriously worn, replace the button bits timely to ensure the
drilling speed. If it¡¯s possible, grind the button bit for reusing.
Replace the button bits once the taper worn, otherwise the buttons
would be seriously abraded and even jammed. ¡¡ |
