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 developedcemented 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.
We produce Tungsten carbide tips in various sizes, tungsten carbide grades and surface conditions.
| Grade | ISO | Density(g/cm3) | Hardness(HRA) | T.R.S.(N/mm2) | Application |
| YT5 | P30 | 12.9 | 90.5 | 2200 | Best strength, high impact and shock resistance among W-Co-Ti alloys, but comparatively lower wear resistance. Suitable for rough turning, rough planning, and semi-finish planning of carbon steel, and alloy steel including forgings, stamped parts, and cast iron surfaces during intermittent cutting. |
| YW1 | M10 | 13 | 92.5 | 1710 | Better hardness, resistant to impact load. A good grade for general purposes. Suitable for machining of ordinary steel, cast irons as well as steels hard to be machined such as refractory steel, high manganese steel, and stainless steel, etc |
| YW2 | M20 | 12.9 | 91 | 1880 | Higher wear resistance and strength, resistant to high impact load. Suitable for roughing and semi-finishing of ordinary steel, and cast irons as well as refractory steel, high manganese steel, and high-grade alloy steel, etc |
| YG6X | K10 | 14.8 | 91.5 | 1890 | Fine grain WC alloy, wear resistance higher than YG6, strength close to YG6. Suitable for machining chilled alloy cast irons, and refractory alloy steel, as well as finishing of ordinary cast irons |
| YG6 | K20 | 14.8 | 89.5 | 2050 | High wear resistance, better impact and shock resistance. Suitable for semi-finishing, and finishing of cast irons, non-ferrous metal, alloys, and non-metallic materials at moderate cutting speed |
| YG8 | K30 | 14.6 | 89 | 2520 | High strength, better impact and shock resistance, but lower wear resistance and cutting speed. Suitable for roughing of cast irons, non-ferrous metal, alloys, and non-metallic materials at low speed. |
| 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. | |
| YG15 | 14 | 86 | 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. | |
| YG20 | 13.5 | 85 | 2600 | Mainly for the stamping dies used in the conditions of heavy impact load and large stress |
