Title:
CIRCULAR SAW BLADE FOR COLD- AND HOT-SAWING METAL, AND MANUFACTURING PROCESS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/113040
Kind Code:
A1
Abstract:
A circular saw blade and a manufacturing process therefor, specifically a circular saw blade for cold- and hot-sawing metal, and a manufacturing process therefor. Said circular saw blade comprises a saw blade body (1), and a hardened wear layer (3) disposed around the outer circumference of the saw blade body (1). The manufacturing process includes: saw blade body (1) blanking, blade body (1) heat treatment, blade body (1) leveling, blade body (1) prepping, blade body (1) fine leveling, build-up welding or cladding pre-processing, hardened wear layer (3) manufacture, finished product leveling, side clearance grinding, tooth processing, and finished product fine leveling. This brings the saw blade within technical requirements, and makes the blade ready for conditions of use on a saw. The saw blade body (1) has a hardened wear layer (3) inside the outer circumference. This maintains long-term sharpness of two sharp corners, decreases burrs and extends cutting life. After the teeth of the saw have dulled, the teeth only need to be repaired, not re-hardened to restore effectiveness. The present invention is particularly capable of processing difficult-to-cut workpieces having high hardness and thick walls.
