The role of carbide saw blades in all angles of TCT saw blade grinding machine
 
 
 
 
1. The rake angle is mainly responsible for controlling the cutting speed, and also for sharpening the main edge and the left and right secondary edges. The smaller the rake angle, the slower the cutting feed speed, which is also suitable for cutting with hard materials. When the front angle is opposite, the cutting feed speed is faster, which is more suitable for cutting longitudinal and soft materials. The rake angle is an important part of the cutting process.
 
2. The rake angle is to reduce the cutting resistance, enhance the cutting of the main and auxiliary blades, improve the sharpness, and reduce the cutting resistance. It plays a key role in fast cutting and increasing cutting speed. In order to make the tool durable, when grinding the rake or rake angle of the blade, when the grinding wheel of the grinding head is withdrawn, the equipment should be equipped with an automatic knife withdrawal device. Otherwise, the grinding wheel will be pressed when the main blade is withdrawn, and the main blade will never be ground. This is also the fatal shortcoming of the current domestic tool manufacturing.
 
3. The role of the relief angle is to control the cutting speed. The smaller the relief angle, the more wear-resistant it is. On the contrary, the rear angle is extremely sharp. In order to make the tool continuous and durable, it is necessary to control the backlash so that each main blade can work continuously at the same time. The tooth gap is generally suitable for hard cutting at 15°, and the tooth gap is not more than 13°.
 
4. The function of the trailing edge angle is to divide the left and right teeth respectively in the cutting section to reduce the cutting resistance and increase the cutting feed rate. When grinding, the center of the base body must be consistent with the center of the grinding wheel. Otherwise, one side of the left and right main inserts will be high or the other side will be low, which will seriously affect the cutting life. Note that the trailing edge angle is not suitable to be greater than 13°. If the trailing edge angle is too large, the main blade is easily broken and the wear resistance is greatly reduced.
 
5. Left and right side angle (plane), roll angle, and roll angle play a role. Tool manufacturing is an important part of determining tool quality. There are several main factors in the machine regulator, such as asymmetry between the center of the base body and the grinding heads on both sides, asymmetry of the cutting edge angle or the grinding line of the grinding head angle, etc. , It will affect the irreparable state of the next process, and the roll angle also seriously affects the cutting effect of the auxiliary blades on both sides. Generally, when the roll angle is greater than 1.5°, a point cut will be formed. It is recommended that the roll angle be less than 1°, so that the second pair of blades can play the role of trimming and planing. When the angle is less than 1°, the cutting resistance does not increase. The flank angle plays a role in heat dissipation during the cutting process. The diameter of the grinding wheel is selected according to the thickness of the grinding wheel and the workpiece to be ground. Generally, the tooth surface angle is between 2.5-3.5°, which is the change of the diameter of the grinding wheel after wear and will not affect the cutting effect.
