Shield cutter machine of Tunnelling tool is a kind of advanced equipment for underground tunnel construction.
This equipment can do the field operation that not affect any construction on the ground.
This is available and best choice for crowd city areas, protecting buildings or historic site on the ground.
There have a very big circle blade in the front of shield cutter machine with cemented carbide shield cutter, We have mounting various kind of cutters on the blade.
In order to promote stable and long life time of application, we have research and developed cemented carbide shield cutter 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 carbide shield cutter insert
cemented carbide shield cutter are normally used for coring softer rock formations, overburden drilling, and cleaning of drill holes
Production and test process of cemented carbide shield cutter
ball grinding mill to produce raw material → press to shape blanks → semi-finished products inspection → sinter blanks to finish (HIP) → finished products inspection
