Miter saws (also called aluminum saws), rod saws, and cutting machines among desktop power tools are very similar in shape and structure, but their functions and cutting capabilities are quite different. A correct understanding and distinction of these types of power tools will help us choose the right power tools. Let's start with the following: To be precise, miter saws, rod saws and cutting machines can all be classified into the category of cutting machines; Very large, far away, such as laser cutting machines, water cutting machines, etc.; in the category of electric tools, cutting machines generally refer to those electric tools that use disc cutting blades, especially those that use grinding wheel slices and diamond slices. Electric tools; the "cutting machine" (desktop) we often say is specifically used to refer to the "profile cutting machine".
Profile cutting machine (Chop saw or Cut off saw) is named because it is often used to cut metal profiles or similar profile materials; cutting materials such as profiles, bars, pipes, angle steel, etc., these materials are characterized by their horizontal Sections are the same. In the early days, due to material and technical reasons, the strength of TCT (Ungsten-Carbide Tipped) saw blades was difficult to use for continuous cutting of metals, especially ferrous metals (Ferrous metal)! Therefore, the conventional profile cutting machine uses resin grinding wheel slices. The main components of grinding wheel slices are high-hardness abrasives and resin binders; grinding wheel slices use grinding to cut metal materials. In theory, they can cut very hard materials, but the cutting efficiency is very low (slow), safe The performance is poor (burst of the grinding wheel), the life of the grinding wheel is also very low (cutting is also a process of self-loss), and grinding will generate a lot of heat, sparks and odors, and the heat generated by cutting may melt and damage the material being cut, so Basically, it will not be used for cutting non-metallic materials.
The full name of pull rod saw is: pull rod compound miter saw, more accurately called sliding compound miter saw, which is an enhanced miter saw. On the basis of the structure of the conventional miter saw, the pull rod saw increases the sliding function of the machine head to increase the size cutting capacity of the machine; because the sliding function of the machine head is usually realized by the linear movement of the slide bar (commonly known as the pull bar), So the image is called a rod saw; but not all sliding miter saws use a rod structure. The rod saw greatly increases the cross-sectional size of the cutting material, so that the material to be cut can be not only a long bar, but also a sheet, so it partially replaces the application of the table saw.
