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.
Main Grade list
It is very important to select the right grade to match the using purpose, need to find the perfect balance between hardness and bending strength, so we have to consider the physical properties of the processing object, as well as the working condition for tools.
| Grade | Density | Hardness | Bend Strength | Application | |
| (G/Cm3) | (HRA) | (TRS/N/mm2) | |||
| YG4C | 15 | 89.5 | 1800 | Maily used as small buttons for percussion bits and as the inserts of rotary prospecting bits to cut soft, medium-hard formations. | |
| YG6 | 15 | 90 | 1700 | Maily used as the buttons of small and medium-sized percussion bits and as the inserts of rotary prospecting bits to cut soft, medium-hard formations. | |
| YG8 | 14.7 | 88.5 | 2200 | Maily used as the buttons of small and medium-sized percussion bits and as the inserts of rotary prospecting bits to cut soft, medium-hard formations. | |
| YG8C | 14.7 | 88 | 2300 | Maily used as the buttons of small and medium-sized percussion bits and as the inserts of rotary prospecting bits to cut soft, medium-hard formations. | |
| YG9C | 14.5 | 87 | 2400 | Maily used as the inserts and buttons for rotary-percussive bits, coal-cutting bits and tricone bits to cut medium-hard and hard formations. | |
| YG11C | 14.4 | 86.5 | 2450 | Chiefly for the inserts and buttons of heavy rock drill bits and rotary-percussive bits, coal-cutting bits and tricone bits to cut medium-hard and hard formations. | |
| YG13C | 14.3 | 86 | 2500 | Mainly used as the inserts and buttons of tricone bits rotary-percussive bits and heavy rock drill bits to cut medium-hard and hard formations. | |
| YG15 | 14 | 86.5 | 2500 | It is stronger, and is mainly used as the inserts and buttons of rotary-percussive bits, heavy rock drill bits to cut hard and very hard formations. | |
| YG16 | 14.10-14.30 | 87.5 | 2400 | It is mainly used for making cemented carbide substrate tips to be used in PDC cutters for excavating coal and oil field PDC bits. | |
| YG20 | 13.40-13.70 | 85 | 2254 | Mainly for the stamping dies used in the conditions of heavy impact load and large strees. |
