Advantages Of Tianying Rotary Rock Bit :
Rotary drill bits are manufactured using aircraft quality steel and
premium carbide grades developed to suit the toughest
application.Computerized designs using solid modeling, computerized
manufacturing processes using the latest in CNC equipment and
computer process controlled heat treatment ensure consistent, high
quality, drill bits. A tailor made cutting structure provides our
customer with the best combination of bit life and rate of
penetration to yield the lowest cost per meter. The gauge will have
Carbide Gauge Inserts to prevent early erosion of the steel. In
very harsh or abrasive conditions additional protection is offered
by applying Hard Facing alloy material to reinforce critical wear
areas of the bit.
Quality Control
In manufacturing, each process goes through an extensive and
painstaking testing ,
quality control is a process that ensures customers receive
products free from defects and meet their needs.
1, Raw material selection:To make a good drill bit, it is necessary
to select the best material and gatekeeping the quality of the
material. We purchase the high-quality steel and strictly control
the material composition and size, it main includes the detection
of the shape, diameter, reamed diameter, length composition, and
flaw of the raw material, Tungsten Carbide and Grease are also the
best raw materials on the market.Besides, we marked every different
piece of materials before transferred to the warehouse.
2, In strict accordance with the ISO9001 international standards
for production.
Carefully control every step of the production, complete each of
the production process,
the production process is including blanking, forging, rough
turning, heat treatment,fine turning, quenching, assembling,
welding, painting, then storage.
Each working process was full inspected, after the qualification,
then move to next working process, which to ensure the 100%
qualified rate.
3, Sampling observation, numbered, packing and arrange the
shipment.

How Does Rotary Rock Bit Work?
Tricone bit is an ideal solution for soft, medium, or hard rock
formations, it is connected with the drill stem and rotates along
with it, and drive cones to pressed on the rock. Each cone rotates
round the axis of its leg and three cones simultaneously revolve
around the bit center. The tungsten carbide inserts on the cone
shell cause the formation to spall under the weight on bit and the
impact load of cone rotating, the debris will be discharged out to
hole by compression air. Tricone bits come in several different
varieties, and can deal with a wide range of different rock
formations. It is important to know the type of formation you are
drilling in when selecting a drill bit.
