Shield machine of turning 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, Protect buildings or historic site on the ground.
There have a very big circle blade in the front of shield machine, 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 special tungsten carbide
materials that mainly suitable for tunnel borer machine: With high impact
toughness, high abrasion resistance, stable physical ability, wide application
field, The appearance of fine workmanship and more.
Product advantages:
1. Wildly used in shield machine.
2. The specification based on the different part of cutters.
3. Easy to install and remove.
4. With high impact toughness, high abrasion resistance.
5. Stable physical ability, wide application field.
6. Top quality and long life time.
7. The appearance of fine workmanship etc.
Quality Inspection:
• Our strict quality control system will testing every batch of
the material in density, HRA, TRS and magnetic saturation, test
report will be kept in our files.
• After we finished production, we need to test it again before we
send them to you, with all mechanical properties.
• We put quality certificates into each carton with
all necessary data, if anything is different from our agreement
or standard, we guarantee that we will send you the replacement
or return the payment.
Our advantages:
1. Professional manufacture for tungsten carbide with more than 15 years’
experience. All products have passed the ISO9001 certifications.
2. We have our own factory to produce the molds and products, so the delivery
is fast. Also we have the professional sales teams to satisfy you well.
3. All products go through in-process and final inspection. Strictly and
complete quality control system.
4. Made from 100% virgin material, stable and reliable quality.
5. We can accept order of all kinds of special designed products of tungsten
carbide.
6. Various payment terms and delivery methods supported.
7. Sample and free online technical service is available.
