Analysis of saw blade grinding machine woodworking saw blade or sawing road deviation
 
 
 
Saw, also known as sawing, is a specific part of the sawtooth tip that is used to cut wood and saw the saw. Let me tell you now what the functions of the saw are:
 
The cutting process is completed by cutting the wood fiber through its cutting edge and the inner and outer edges.
 
In the process of row sawing, the kerf is enlarged, the friction between the saw blade and the cutting surface is reduced, and the saw blade is prevented from running due to friction and heat.
 
During the sawing process, the cutting direction is controlled and the sawing advances.
 
The main reason for the saw blade grinding machine woodworking saw blade or sawing road deviation:
 
One is caused by the saw blade not being correctly formed under the premise that the saw blade has the correct shape of the sawtooth;
 
The second is caused by the incorrect shape of the saw blade serration under the premise that the saw blade is correct;
 
The third is that the saw blade is centered on the center of the saw blade. When the two sides are subjected to resistance or reaction forces, the saw blade has an offset (referring to deformation. Even if the saw blade is pulled tightly, this phenomenon will occur).
 
The fourth is caused by the above three reasons.
 
The saw blade sawing and sawtooth shape is correct or incorrect. It has a direct relationship with the correctness of our sawing and sawing. The following two problems are analyzed: the 掰 (open) sawing path and the erroneous sawing are incorrect. The main reason for the correct deviation of saw blade or sawing when sawing wood:
 
1. 掰 (open) sawing problem
 
The saw blade is to be smashed (opened), and the way to open the saw is to use the squeegee to have a regular pattern (there are many rules, not to be elaborated here), and the sawtooth tip is turned to the left and to the right (middle) The teeth are not 掰) a certain size (including the angle). In the correct shape of the sawtooth (the reason for the incorrect zigzag shape) is based on the center line of the saw blade, and the dimensions (including the angle) of the left and right serrations should be as uniform as possible. For example, when the size of the zigzag to the left is larger than the size of the right cymbal, when sawing the wood, the resistance or reaction force of the sawtooth to the left is greater than the sawtooth of the right cymbal, and the saw blade has a certain offset (deformation). The sawing road will deviate to the right. The opposite is also true.
 
 
2. Saw blade grinding machine sawtooth shape problem
 
Some wooden friends may say: "It is clear that my sawings (open) are correct (the dimensions to the left and right are the same or substantially the same), and the phenomenon of sawing deviations will occur when used." This phenomenon does exist in practice. I believe that the main reason for this phenomenon is that the angle between the processing surface of the boring tool and the saw blade is incorrect and the shape of the sawtooth tooth (especially the tip of the tooth) is incorrect. Secondary reason).
 
3. summary
 
1) When sawing wood, the main reason and the direct cause of the sawing deviation are directly related to the saw blade, the size of the sawtooth (including the angle), the shape and the resistance or reaction force it receives.
 
2) Generally speaking, when the saw blade is smashed (open), the sawing path on the x side is large, and the resistance or reaction force of the x-edge serration is large when sawing wood, and the saw blade or sawing path is opposite to the x-side. Deviation.
 
3) When jagged, from the top view (viewed from top to bottom) and the left view (from left to right), as long as the angle between the boring surface and the saw blade is incorrect (not 90 degrees), the angle between the sides of the serrated tip It will show asymmetry. Taking the middle line of the saw blade as the standard, the x-edge tip is obtuse and for a long time. During the sawing process, the resistance or reaction force on the x-edge is large, and the saw blade or saw-saw will deviate in the opposite direction of the x-edge.
 
4. Other
 
1) The ability and time are limited. The opinions of this article are improper or incorrect. The expressions of the text and the pictures are not clear. We welcome the good comments and axe of the wood friends.
 
2) Some wooden friends (especially novices) may ask: "How can I slap (saw) the saw blade's sawing path, that is: how to ensure or basically guarantee the left and right slashes in size (or angle) Consistency?" My answer is: First, practice more. Second, you can use your teeth on a dental appliance to solve this problem by yourself using a device with a limited size or angle device (backing).
