Shield cutter machine of Tunnelling tool is a kind of advanced
equipment for underground tunnel construction. There have a very big circle blade in the front of shield cutter
machine with tungsten carbide cutter blade.
In order to promote stable and long life time of application, we
have research and developed tungsten carbide cutter blade with special material that mainly suitable for tunnel borer
machine: high impact toughness, high abrasion resistance, stable
physical ability, the appearance of fine workmanship etc.
Application of tungsten carbide cutter blade
tungsten carbide cutter blade are normally used for coring softer rock formations.
tungsten carbide cutter blade also use to overburden drill, and clean drill holes
Production and test process of cemented carbide shield cutter
1, Soon after the order is confirmed, tungsten carbide cutter blade 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 cutter blade 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 cutter blanks must be passed by semi finished
inspection,
4, Then sinter blanks to finish (HIP) and finished products
inspection, we have10 sets of vacuum sintering furnace and 2set of
HIP in the factory ensure the best quality and production capacity.
5, 1). cleaning/tumbling is to make the tungsten carbide cutter
look more beautiful.
2).The tungsten carbide cutter can be ground according to
customers’ order to a tolerance of +/-0.05
Packing and delivery of tungsten carbide cutter blade
Liking below picture show, before packing, we need to clean
product.
Then wrapped tungsten carbide cutter blade in paper and put into inner small carton box
Next, put the inner box into outter carton and fill the carton with
foamed plastic
Four, wrap the carton with packaging tape
Last, you can choose any delivery way such as DHL,TNT,UPS ect.
