Cold saw machine: high-speed circular saw machine speed 60-140 r/min BS (fast cut) SMS (slow cut) feed speed 0.06 m/sec, which is greater than that it is a fast and solid material, with more teeth with high density (fast cut), less teeth with low density (slow cut) cutting pipe, thin walls with fewer teeth, thick walls with fewer teeth, cut alloy steel about 65-140 r/min, cut stainless steel 75-85 r/min, cut high temperature alloy 40 r/min Advantages: Use cermet cutter heads, SKS51 alloy steel plate imported from Japan, greatly improves durability, high cutting efficiency, no burrs, low cost, no coating, low carbon steel No. 10, 20, medium carbon steel No. 45 (the most on the market), high carbon steel No. 65, etc., alloy steel, bearing steel; the coating can be cut titanium alloy, high temperature alloy and stainless steel (stainless steel is easy to stick to the knife, so it is coated)

Diamond is a super hard material with very strong cutting ability. Therefore, it is widely used in various processing factories, such as the door and window industry, and some super hard wood materials, which are used in this kind of saw blade inlaid with diamond heads. Compared with ordinary saw blades, although diamond saw blades are priced at high prices, their cutting cycle and cutting volume are large, and their service life is more than 20 times that of ordinary saw blades. The reason why diamond saw blades are durable is mainly reflected in their cutting heads. They are made of PCD diamond cutters. They are wear-resistant and durable. Many diamond saw blades use diamond saw blades. The specific one depends on the manufacturer's choice. Some are too high to accept the price, and they will settle for the second best choice. In fact, if the high price of gold and steel stone saw blades is excluded, it is the 'disadvantage' of the high price of gold and steel saw blades, it is currently the most durable saw blades on the market. However, because diamond saw blades are of wide variety and widely used, many customers do not know how to buy them correctly.

Fly saw blades are used on contour saws, used to cut stainless steel pipes, carbon steel pipes, copper pipes, etc. In recent years, more and more high-speed hacksaw blades have been replaced by flying saw blades. Because the flying saw blades are very smooth and have almost no burrs, and large-sized flying saw blades are cheaper than high-speed hacksaw blades of the same size, customers finally chose the flying saw blades. In addition, the flying saw blades also have special PVD coatings and special tooth angles, which greatly increases the service life and wear resistance of the saw blades, making the cutting effect the best.

The thickness of the cold saw blade directly determines the amount of loss of the saw blade during use, that is, the amount of sawdust. Although some people think that the thinner the thickness of the saw blade, the better, and the less sawdust, if the thickness is too low, it will cause a slant. Therefore, the thickness of the saw blade should be selected well. It is best to find the same path and stability. If the saw blade is too thin, it will not be stable enough when running, which will easily reduce the quality of the workpiece. This may affect the production of the enterprise. Therefore, it should be considered from the comprehensiveness. The thickness should be selected from the actual situation. You cannot blindly pursue specifications, otherwise it may be counterproductive.

Acrylic is a special material, usually used to cut explosive edges and cracks. It is very different from the woodworking saw blades used to cut wood. Usually, customers use BA5 tooth shape to cut the tooth shape of acrylic acrylic blades. The teeth are flat on the left and right sides. According to the brittle and hard characteristics of acrylic, cutting non-explosive edges. Generally speaking, the teeth of the woodworking saw blades are relatively thin. The teeth of the woodworking saw blades are left and right teeth. The sharp cutting wood is particle board saw blades usually have 300x3.2x30x72 teeth and 300x3.2x30x96 teeth.

1. Basic data before selecting saw blade processing spindle speed processing workpiece thickness and material saw outer diameter I and aperture (axis diameter) 2. Select based on the cutting speed is v=π, and the reasonable cutting speed is calculated from the number of spindle rotations and the matching saw blade outer diameter × outer diameter D × rotation number n/60 (M/s). Generally, the reasonable cutting speed is 60-90. M/s material cutting speed; soft wood 60-90 (M/s) hardwood 50-70 (M/s) particle board plywood 60-80 (M/s) If the cutting speed is too high, the vibration noise of the machine tool is high, the stability of the saw blade is reduced, the processing quality is reduced, the cutting speed is too small, and the production efficiency is reduced. At the same feed speed, the cutting amount per tooth increases, which affects the processing quality and service life of the saw blade. Since the relationship between the saw blade diameter D and the spindle speed n is a power function, in practical applications, it is the most economical to reasonably increase the speed and reduce the saw blade diameter.
