the carbide circular saw blades

The actual selection of circular saw blades sawing to consider is the type of material thickness, cutting speed, cutting direction, feed rate, saw the road width and other  masonry saw blades  specific issues. These problems ultimately attributed to the saw blade tooth, angle and other parameters of selection, the following parameters for the blade geometry make a brief introduction:
1, saw tooth choices
Tooth circular saw blade is divided into left and right teeth, conical teeth, flat teeth, trapezoidal tooth, crescent-shaped teeth, etc., the actual use based primarily on the type of material to be sawn to choose.
① around teeth for open bar and crosscut saw all kinds of soft and hard wood and particleboard, equipped with anti-rebound protection around the tooth for tooth longitudinal cutting various sections of the plate with trees, with a negative rake angle of the saw teeth around piece due sharp serrated, cutting good quality, usually used plywood sawing.
② conical teeth commonly used in the  grinding cup wheel groove panel saw blade, in the double sawing plywood veneer, the groove bottom grooving saw the completion, the main plate sawing sawn finish to prevent the collapse occurred Jukou ballast phenomenon.
Flat teeth mainly used for general cutting of wood, this blade low cost, but rough saw cut.
③ trapezoidal tooth peace teeth used in combination unworthy groove sawing blade also get a higher quality when cutting veneer crack phenomenon does not occur for a variety of dual-veneer plywood sawing.
2, the choice of jagged angles
Angle parameter serrated portion is complex, and the  sand paper correct choice of the blade cutting angle parameter is to determine the quality of the key. The main point of argument is the rake angle, clearance angle, wedge angle.
Rake angle sawing wood consumed by the main impact force. Serrated cutting rake angle greater sharpness better, more portable sawing, pushing more effort. Generally relatively soft material to be processed, the selected larger rake angle, otherwise choose a smaller rake angle.
