OEM 90HRA TUNGSTEN CARBIDE BUTTONS CEMENTED CARBIDE BUTTONS CARBIDE
TIPS CARBIDE PICKS CARBIDE INSERTS
DESCRIPTION:
The carbide buttons sintered by coarse-grained cemented carbide,
with the properties of high hardness and good transverse-rupture
strength, corrosion resistance, and resistance to acid and alkali,
long service life. These Button tips have many types:
the cutting tips used by cold pavement milling-planing machine;
the cutting tips used by rotary digging machinery;
the cutting tips used by coal digging machine;
the cutting tips used by roadway and tunnel boring machine;
the cutting tips used by trench excavator, etc.
They are widely used for crushing or milling rocks.
APPLICATION:
There are high performance for percussion drilling, rotary
prospecting bits to cut soft and medium-hard formations, and
medium-hard drilling bits, also used for hardwood, non-ferrous
metal, granite, and marble.
SPECIFICATION:
Mining tools include rock drilling bits, coal cutting bits, for
mining tools

PRODUCTION DEMONSTRATION:
Types and Specifications:
PRODUCTION PROCESS AND TEST:
1) The powder of Carbide Buttons will be prepared as per the
customer’s requirement with our wet-grinding machine.
2) Before mass production, we take a trial pressing and sintering,
and we check the appearances and the sizes of the samples with a
micrometer to ensure that the requirements of the performance can
be met before batch production.
3) There is a pilot inspection before every bulk production, press
the raw materials to shaped blanks, and carbide tips.
4) Finished product inspection to ensure the best quality and
production capacity.
