Tungsten Carbide circular blades for cutting slitting corrugated
board MR020
Description:
Tungsten carbide round balde is supplied in a range of standard
sizes for cutting paper,carton in corrugated industry .
These kinds of carbide round knives are specially manufactured for
cutting off and slotting metal materials such as plain steel,
chilled steel, aluminum and copper as well as difficult-to-machine
materials such as stainless steel, titanium alloys and printed
circuit board.
Our tungsten carbide round knives are precision made to reach a
high standard, with specially
ground finish and tooth. Compared with the high speed steel saw, it
can perform high speed cutting, with a high machining efficiency,
accurate slitting and good surface finish.
Applications:
Tungsten carbide disc slotting knives is suitable for cutting
paper,carton box in printing industry
Metal and its alloy. It is also suitable for semifinishing and
finishing the hardened steel
and alloy steel.

About Lifetime of tungsten carbide knife for cutting paper :
If using fast cutting equipment , the lifetime can be over 2
million running meters .
If using low cutting machine,the lifetime can be over 5 million
running meters .
Factors that will influence the blade's lifetime :
1.To cut which material
2.Cutting machines are not same
3.Assemblage’s grinding tolerance
4.Over grinding for blade
5.Using different quality blade from different factories.
6.Using raw material or using recycle material

tungsten carbide steel knife is mainly used for cutting paper,
rubber, plywood, hardwood, PCB, PVC, stainless steel, high
manganese steel and PCB, PVC electronic circuit boards and other
materials.
tungsten carbide steel knife products require high precision, no
glitches, maximum abrasion resistance.
we are using HIP sintered and fine grinding, polishing plating to
reduce frictions when cutting, improved the accuracy and speed
slitting greatly, tool life extended!
1, Soon after the order is confirmed, tungsten carbide steel knife
products will start to prepare the RTP powder as per customer’s
requirement with our wet-grinding machine
2, Before mass production, we need to do a trial pressing and
sintering using every mould, and we check the appearances and the
sizes of tungsten carbide steel knife samples with micrometer, projectors etc. 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 all
tungsten carbide steel knife blanks must be passed by semi finished
inspection,
4, Then sinter blanks to finish (HIP) and finished products
inspection, we have 10 sets of vacuum sintering furnace and 2 sets
of HIP in the factory ensure the best quality and production
capacity.
