Problems solved by technology

After market research and experiments, saw blades capable of dry cutting are generally not suitable for long-term dry cutting operations. Taking dry-cut stone saw blades with a diameter of 114 mm as an example, in the case of dry cutting, the saw blade can cut more than 20 meters continuously. The phenomenon of burning cutter heads began to appear one after another. Some brand products showed burning cutter heads after continuous cutting of about 10 meters

Embodiment 1

[0013] Take 40 grams of iron powder, 60 grams of copper powder, 40 grams of nickel powder, 40 grams of tungsten powder, 20 grams of tin powder and 8 carats of diamonds with a particle size of 45 / 50#HWD60 and mix them. The mixture is first combined with the matrix by cold pressing, A cold-pressed green body is formed, which is then sintered by metallurgical processes to make a diamond cutting head, which is then made into a saw blade.

[0014] The sintering strength of this diamond cutting saw blade is 4N.M. When cutting 19mm thick Shandong Wulianhua stone material with this diamond dry slice, the burnt head will appear after continuous cutting for about 30 meters.

[0015] The sintering strength refers to the bonding strength of the substrate and the cutter head during sintering. The higher the sintering strength, the more durable the saw blade is, and it is an important index to measure the performance of the saw blade.

Embodiment 2

[0017] Take 40 grams of iron powder, 60 grams of copper powder, 40 grams of nickel powder, 40 grams of tungsten powder, 20 grams of tin powder, 8 carats of diamond with a particle size of 45 / 50#HWD60 and 1 gram of carbon fiber powder with a particle size of 200 The mixture is firstly combined with the matrix by cold pressing to form a cold-pressed green body, which is then sintered by metallurgical processes to make a carbon fiber-containing diamond cutting head, and then made into a saw blade.

[0018] The sintering strength of the diamond dry slice is 5N.M. When the dry slice is used to cut 19mm thick Shandong Wulianhua stone, a slight burning phenomenon occurs when cutting about 50 meters.

Embodiment 3

[0020] Take 40 grams of iron powder, 60 grams of copper powder, 40 grams of nickel powder, 40 grams of tungsten powder, 20 grams of tin powder, 8 carats of diamond with a particle size of 45 / 50#HWD60 and 2 grams of carbon fiber powder. The particle size of the carbon fiber powder is 200 The mixture is firstly combined with the matrix by cold pressing to form a cold-pressed green body, which is then sintered by metallurgical processes to make a carbon fiber-containing diamond cutting head, and then made into a saw blade.

[0021] The sintering degree of the diamond dry slice is 6N.M. When the dry slice is used to cut 19mm thick Shandong Wulianhua stone, a slight burnt phenomenon occurs when cutting about 100 meters.

Abstract

The invention relates to a diamond dry-cutting saw web and specifically relates to a diamond dry-cutting saw web and a manufacturing method thereof. The diamond dry-cutting saw web comprises a substrate and a tool bit; the substrate is combined with the tool bit by use of a hot-pressing process; a plurality of metal powders used for the tool bit contain a carbon fiber powder; the weight of the carbon fiber powder accounts for 0.5%-1.5% of the weight of the plurality of metal powders; the granularity of the carbon fiber powder ranges from 200 to 500 meshes; the manufacturing method comprises the following steps: the substrate is combined with the tool bit by use of the hot-pressing process; the carbon fiber powder is added to the plurality of metal powders used for the tool bit and mixed evenly; the weight of the added carbon fiber powder accounts for 0.5%-1.5% of the weight of the plurality of metal powders; the granularity of the carbon fiber powder ranges from 200 to 500 meshes; the carbon fiber diamond dry-cutting saw web manufactured has the advantages of no tooth burning, high combination strength of the substrate and the tool bit, long dry cutting time, and safety and reliability, and also the advantage of high sintering strength.

Description

technical field [0001] The present invention relates to a diamond dry-cut saw blade, and also relates to a manufacturing method of the diamond dry-cut saw blade. Background technique [0002] At present, most diamond saw blades are used for wet cutting with water added, and most of the saw blades that can be used for dry cutting on the market are less than 230 mm in diameter. After market research and experiments, saw blades capable of dry cutting are generally not suitable for long-term dry cutting operations. Taking dry-cut stone saw blades with a diameter of 114 mm as an example, in the case of dry cutting, the saw blade can cut more than 20 meters continuously. The phenomenon of burning cutter head began to appear one after another, and the burning cutter head appeared in some brand products after continuous cutting of about 10 meters. Therefore, it is a market demand to produce a new type of diamond dry slice that can cut continuously for a long time, and it can ...
