Hard alloy cemented carbide small round knife for cutting pvc tube plastic
Description:
Tungsten carbide round cutter is supplied in a range of standard sizes for wood and steel-sawing applications.
These kinds of carbide round cutters 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 cutters 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:
For computer hard disk head industry;
For cutting/scoring the pcb board,rubber;
For artificial crystal slotting/cutting;
For jewellery (gold, silver, copper)accessory industry;
For metal (alloy) precise cutting/slotting
Grade and Applications:
| Grade | Hardness | TRS | Density | Application |
| MR020 | 91-92 | 3000-3100 | 14.45 | For cutting corrugated board or pvc,plastic |
| MR030 | 91-92 | 3100-3200 | 14.15 | For fast cutting corrugated paper.pvc,rubber |
Production process
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.
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
About tolerance
Outside diameter : +-0.05mm,ID H7,Thickness : +-0.05 . Product roughness clamping surface :Ra 0.4, mesa Ra0.2, sharp edge : Ra0.2, Sharp edge angle : 18°-20°
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 .
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!
