Abstract

The invention provides a method for preparing a stainless steel cutting cold saw and a saw blade of a cold saw. The method comprises the following steps: performing stress treatment on a circular saw blade base body; controlling the welding precision of a specially-shaped tool bit; processing a low-friction-coefficient chip guiding slot, a chip breakage slot, a tipping prevention edge, a cutting edge and a low-friction-coefficient side surface on the tool bit; performing cutting edge passivation and TiAlN coating treatment after the tool bit is processed. The saw blade prepared according to the method comprises a saw blade base body, sawteeth arranged on the circumference of the saw blade base body and a mounting hole formed in the saw blade base body, a chip breakage slot is formed in a rear tool face of a sawtooth tool bit, a tipping prevention edge is cut at the intersection of the rear tool face and an upper end main side surface of the sawtooth tool bit, a cutting edge is formed at the junction part of the front tool face and the rear tool face, and a chip guiding slot is formed in the front tool face connected with the cutting edge. The saw blade has the benefits of wear resistance and heat resistance; the chip sticking resistance is improved and the service life is prolonged.

Description

technical field [0001] The invention relates to a preparation method of a cold saw for cutting stainless steel and a saw blade thereof, belonging to the technical field of surface coating. Background technique [0002] Cold saws produced with special-shaped cermet blades have been widely used in the field of metal cutting, but the difficulty of cutting stainless steel with high quality and high life has not been solved. At present, the slow speed cutting of band saw blades is the main method. [0003] The development and application of surface coating technology has played a key role in the improvement of tool performance and the progress of cutting processing technology. Coated tools have become an important symbol of modern high-end tools. The principle of coating is to coat one or more layers of high wear-resistant refractory compound on the cutter body to improve the performance of the cutter, achieve the purpose of improving processing efficiency, prolonging the life of...
