The invention discloses a precise cutting saw. The precise cutting saw comprises a saw blade base body with a mounting hole and tungsten steel tool bits, wherein sawteeth are arranged on the outer edge of the saw blade base body in the circumferential direction; tooth bottom chip-hold grooves are formed between the adjacent sawteeth; the tungsten steel tool bits are welded to saw blade base body tooth holders, facing the cutting direction, of the sawteeth; the cutting faces of the tungsten steel tool bits face the cutting direction; the cutting edge of each tungsten steel tool bit is in an inclined shape with one end higher than the other end; every three adjacent tungsten steel tool bits form a group; the interval angle of every two adjacent tungsten steel tool bits in the group in the circumferential direction of the saw blade base body is sequentially alpha and beta in the clockwise direction; the interval angle of every two adjacent groups in the circumferential direction of the saw blade base body is gamma; and radiating grooves are formed in the saw blade base body. The saw blade base body with enough strength and the tungsten steel tool bits with long service life are adopted, and the tungsten steel tool bits are inclined, so that the cutting effect can be achieved; and the radiating grooves are formed, so that heat dissipation of blades is easier, and cutting of a saw blade is light and fast. Precision and smoothness can be guaranteed, the cutting service life of the saw blade is prolonged, and the production efficiency is improved.
Description
technical field [0001] The invention relates to a precision cutting saw. Background technique [0002] In the field of wood processing, because users have higher and higher requirements for the dimensional accuracy and smoothness of the cutting surface, the conventional cutting saw blades used in the past have low dimensional accuracy and short processing life. Contents of the invention [0003] In order to overcome the above problems, the present invention provides a precision cutting saw that can not only ensure the precision, but also increase the cutting life of the saw blade and improve the production efficiency. [0004] The technical solution adopted in the present invention is: a precision cutting saw, including a saw blade base body with a mounting hole and a tungsten steel cutter head, saw teeth are provided on the outer edge of the saw blade base body, and tooth bottom chip holders are provided between adjacent saw teeth Tungsten steel cutter head is welded on ...
