Factory Price Tungsten Cemented Carbide Button Inserts For Milling Bits
Description:
The carbide buttons are sintered by coarse-grained cemented carbide, with properties of high hardness and good transverse-rupture strength, and corrosion resistance, resistance to acid and alkali, long service life.
They are mainly classified as follow usages: Normally, 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:
Carbide button bits are also indispensable parts of coal cutter drilling tools, mining machinery and road maintenance tools. They fit perfectly on roller cone bits, DTH bits, drifter bits, etc
Feature Advantage:
According to different oilfield drilling machines, such as cone
drills, down-the-hole drills, geological drilling tools, carbide
ball teeth are divided into different standard styles: P-type flat
top position, Z-type coin ball position, X-type wedge position.

Production and test of Tungsten carbide Buttons:
1)Carbide Buttons will start to prepare the powder as per the customer’s requirement
with our wet-grinding machine
2) Before mass production, we need to do 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 drawings can be met before
batch production
3) Bulk production, press the raw materials to shape blanks, and
carbide tips must be passed by semi-finished inspection.
4) sinter blanks to finish (HIP) and finished products inspection
to ensure the best quality and production capacity.
