Many times, we may have some unexpected situations when using the drill bit, so how to deal with these situations? Just follow me,
we, a professional rock drilling equipment manufacturer & drill rig factory supplier in China will give you the right answer.
Although the tungsten carbide bit can be autonomously grinned, in order to get a higher penetration speed and longer working life,
the buttons need to be sharpened. The main failures of bits include: gauge buttons wear to flat, button cracks or button drop out,
etc. If the damaged bits are not grinded timely. The penetration speed would decrease and bit tends to worn out easily.
1. Bit button failures
A. Gauge button cracks. Although one or two-button cracks won’t affect continuous drilling, it would aggravate other buttons’
failure and reduce the button bit life.
B. Bit body or bits head surface damages usually lead to front buttons and gauge buttons drop out.
C. Due to too long service life of tungsten carbide, a snakeskin patterned cracking might show up on carbide surface. If the bit
continues serving, the cracks would expand until final failure.
2. Sharpening Standard
Regardless of any sharpening rules, once the button is flat or a snakeskin pattern shows up, Bit needs to be sharpened. The
ultimate diameter of flatted carbide is half its original diameter; while in hard formations, it’s less than 5 mm.
3. Sharpening process
A. Tungsten carbide sharpening. When sharpening, sketch a linear line in the central of the carbide flat face. Under orientation
of the linear mark, grinding the carbide sides to round shape by a pneumatic grinding wheel, after that, rounding the carbide
along the line. The rotation speed of the grinding wheel should be 20000-25000 r/min.
B. Flushing slot grinding. Bit body metal can’t be removed too much; otherwise, the supported around carbide becomes too weak,
which easily results in button drops.
C. Pay more attention to the gauge button the support around carbide becomes angles and if bit body metal exceeds too weak, which
easily results in the gauge button, the exceeded button drops section should be removed.
