Tunnel borer carbide tips are widely used in petroleum, natural
gas, coal, road construction and other types of mining exploration,
mining excavation and processing areas in which tools are mainly
as petroleum drill bits, coal cutting bits, milling planer bits, geologic
tools, compound drill bits and their completed tools.
Tunnel borer carbide tips are very advanced underground tunnel
construction equipments, it does not affect the ground condition
under the conditions of operation, thus greatly improve the
feasibility of the construction and reduce the cost.
Shield 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 machine. And various kind of cutters
are mounted on the blade. In order to promote stable and long life time of application, we
have research and developed special tungsten carbide materials that mainly suitable for
tunnel borer machine: high impact toughness, high abrasion resistance, stable physical ability,
the appearance of fine workmanship etc.
