          How to choose a carbide circular saw blade?

          Release date:2020-11-18 Author: Click:

              Cemented carbide saw blades include various parameters such as the type of alloy blade, the material of the substrate, the diameter, the number of teeth, the thickness, the tooth profile, the angle, and the aperture. These parameters determine the processing capacity and cutting performance of the saw blade. When choosing a saw blade, the saw blade should be selected correctly according to the type of sawing material, thickness, sawing speed, sawing direction, feeding speed, and saw road width.


              1. Choose cemented carbide saw blade according to working environment


              1. 65Mn spring steel has good elasticity and plasticity, economical material, good heat treatment hardenability, low heating temperature, easy deformation, and can be used for saw blades that require low cutting requirements. Tungsten steel alloy manufacturer  


               2. Carbon tool steel has high carbon content and high thermal conductivity, but its hardness and wear resistance drop sharply when exposed to 200℃-250℃ temperature, heat treatment deformation is large, poor hardenability, and long tempering time is easy to crack. Manufacture economical materials for tools such as T8A, T10A, T12A, etc. Carbide saw blade


              3. Compared with carbon tool steel, alloy tool steel has better heat resistance, wear resistance and better handling performance. The heat deformation temperature is 300℃-400℃, which is suitable for manufacturing high-grade alloy circular saw blades. 


               4. High-speed tool steel has good hardenability, strong hardness and rigidity, and less heat deformation. It is ultra-high-strength steel with stable thermoplasticity and suitable for manufacturing high-end ultra-thin saw blades.


              2. Workpiece size and common diameter selection of carbide saw blades


                 The diameter of the carbide saw blade is related to the sawing equipment used and the thickness of the sawing workpiece. The diameter of the saw blade is small, and the cutting speed is relatively low; the large diameter of the saw blade has higher requirements on the saw blade and sawing equipment, and the sawing efficiency is also high. The outer diameter of the saw blade is selected according to different circular saw machine models to use the saw blade with the same diameter. The diameters of standard parts are: 110MM (4 inches), 150MM (6 inches), 180MM (7 inches), 200MM (8 inches), 230MM (9 inches), 250MM (10 inches), 300MM (12 inches), 350MM ( 14 inch), 400MM (16 inch), 450MM (18 inch), 500MM (20 inch), etc., the bottom groove saw blades of precision panel saws are mostly designed to be 120MM.


              

              Three, according to the processing technology and the choice of carbide saw blade tooth profile


              Commonly used tooth shapes include left and right teeth (alternating teeth), flat teeth, ladder flat teeth (high and low teeth), inverted trapezoidal teeth (inverted cone teeth), dovetail teeth (hump teeth), and rare industrial grade three Left and right, left and right flat teeth, etc. 


               1. The left and right teeth are the most widely used, the cutting speed is fast, and the grinding is relatively simple. It is suitable for cutting and cross sawing various soft and hard solid wood profiles and density boards, multilayer boards, particle boards, etc. The left and right teeth equipped with anti-repulsion protection teeth are dovetail teeth, which are suitable for longitudinal cutting of various boards with tree nodes; the left and right tooth saw blades with negative rake angle are usually used for pasting because of their sharp teeth and good cutting quality. Sawing of panels.


                2. The flat tooth saw cut is rougher, the cutting speed is slower, and the grinding is the simplest. It is mainly used for sawing of ordinary wood and has a lower cost. It is mostly used for aluminum saw blades with smaller diameters to reduce adhesion during cutting, or for grooving saw blades to keep the bottom of the groove flat. 


               3. Ladder flat teeth are a combination of trapezoidal teeth and flat teeth. The grinding is more complicated. It can reduce veneer cracking during sawing. It is suitable for sawing of various single and double veneer wood-based panels and fire-resistant boards. In order to prevent adhesion, saw blades for aluminum use more saw blades with flat teeth. 


              4. The inverted ladder teeth are often used in the bottom groove saw blade of the panel saw. When sawing the double-faced wood-based panel, the groove saw adjusts the thickness to complete the grooving of the bottom surface, and then the main saw completes the sawing of the board. Prevent edge chipping in the saw edge. 


              Fourth, according to the choice of processing equipment and carbide saw blade aperture


                Aperture is a relatively simple parameter, which is mainly selected according to the requirements of the equipment. However, in order to maintain the stability of the saw blade, it is best to choose a larger aperture for the saw blade above 250MM. At present, the diameters of standard parts designed in China are mostly 20MM holes for 120MM and below, 25.4MM holes for 120-230MM, 30 holes for more than 250, and some imported equipment also have 15.875MM holes. The diameter of multi-blade saws is relatively complicated. , There are many keyways to ensure stability. Regardless of the size of the aperture, it can be modified by a lathe or a wire cutting machine. The lathe can be turned into a gasket with a large hole, and the wire cutting machine can expand the hole as required by the equipment.  A series of parameters such as the type of alloy cutter head, the material of the base body, the diameter, the number of teeth, the thickness, the tooth profile, the angle, the aperture, etc. are combined into the whole of the carbide saw blade. It is necessary to select and match reasonably to better exert its advantages.
