diamond core drills line describes the role of the saw blade

Saw blade about the role of the first line is used to cut a sheet of solid material circular tool collectively. Blade can be divided into: diamond saw blade for stone cutting; materials for metal cutting HSS film (not inlaid carbide tip); for wood, furniture, plywood, aluminum, aluminum , radiators, plastics, steel and other cutting carbide saw blades. Carbide alloy GUSHI stone drill bits  containing carbide saw blade type, a plurality of parameters of material, diameter, number of teeth, thickness, profile, angle, pore size of the matrix, which determine the processing capacity and the cutting blade. When you select the type of cutting blade according to the material, thickness, cutting speed, cutting direction, feeding speed, road width requires the correct selection of the saw blade. (A) the choice of carbide species commonly used types of tungsten carbide cobalt (Code YG), tungsten, titanium category (Code YT). Select ⒈ (two) 65Mn spring steel substrate elasticity and plastic, the material economy, good hardenability heat treatment, the heating temperature is low, deformation can be used for less demanding requirements of the cutting blade. ⒉ carbon tool steel carbon high thermal conductivity, but by 200 ℃ -250 ℃ temperature sharp decline in its hardness and wear resistance, heat treatment deformation, poor hardenability, tempering a long time easy to crack. Materials such  GUSHI cutting disc for drill as tool manufacturing economy T8A, T10A, T12A and so on. ⒊ alloy tool steels compared with carbon tool steel, heat resistance, wear resistance, good processing performance, heat distortion temperature of 300 ℃ -400 ℃ suitable for the manufacture of high-grade alloy saw blade. Permeability, hardness and rigidity ⒋ speed tool steel with good quenching, less heat distortion, is ultra-high strength steel, suitable for the manufacture of high-grade thermoplastic stable thin saw blade. (C) the choice of diameter and thickness of the blade diameter sawing equipment used for sawing and related artifacts. Blade diameter is small, the cutting speed is relatively low; blade diameter saw blade and cutting equipment requirements will be higher, while cutting efficiency is high. The outer diameter of the circular saw blade different  machine models choose to use according to the diameter of the blade matches. (D) Select the number of teeth of the serrated teeth, the teeth more generally, the more the cutting edge per unit time, the better the cutting performance, but required more and more carbide cutting teeth number, the price of the blade high, but the jagged too close, the teeth of the chip becomes smaller, easy to cause the blade fever; another jagged too, when the feed rate mismatch, it rarely cut per tooth, will exacerbate friction with the workpiece edge , affect the life of the blade. Typically tooth pitch 15-25mm, should be selected based on a reasonable number of teeth sawing material. (E) the choice of the thickness of the blade thickness theoretically we hope blade thinner the better, is actually a kerf consumption. Materials and manufacturing processes alloy saw blade matrix determines the thickness of the blade, the thickness is too thin, easy to shake when the blade work, the impact of cutting effect. To consider when GUSHI abrasive grinding wheels  selecting blade thickness from work and the stability of the blade sawing materials. Some special-purpose material thickness are also specific requirements, equipment requirements should be based on use, such as slotting saw blades, saw blades crossed. (F) the choice of common tooth tooth tooth left and right (alternating teeth), flat teeth, flat teeth ladder (low gear), inverted trapezoidal tooth (inverted conical teeth), dovetail teeth (tooth hump), and does not common industrial grade three left-right, left right left right flat teeth and so on. ⒈ the most widely used around the teeth, fast cutting, grinding is relatively simple. For open crosscut saw all kinds of materials and soft and hard wood profiles and MDF, plywood, particle board, etc. Equipped with anti-rebound force protection around the tooth tooth tooth is dovetail for longitudinal cutting of all kinds have burl panels; around tooth saw blade with a negative rake angle due to the sharp serrated, good cutting quality, typically used for stickers panel sawing.
