(1) Cutting machine power N: N = Ft × V. Ft is the tangential cutting force, V is the aluminum abrasive cutting disc wire speed; where F1 is subjected to abrasive hardness, cutting piece self-sharpness, cutting piece strength, cut material hardness, size The radial pressure at the cutting point is determined by many factors, and F1 is an important factor affecting the maximum size of the workpiece.

(2) Cutting machine speed n: The speed of the cutting piece determines the linear velocity v, which determines the relative movement speed of the cutting piece and the workpiece. This is very important for the cutting efficiency. The higher the speed, the better the strength is.

(3) Radial pressure Fn at the cutting point: For the cutting method, the tangential force Ft can be formed by the radial force Fn; the larger the Fn, the larger the Ft; the Fn/Ft is between 1.5 and 3, but The resultant force F of Fn and Ft is determined by the strength of the cutting piece, the strength of the abrasive, and the like.

experiment method:

Although there is no quality evaluation in China at present, it will not be enforced; however, it is necessary for each manufacturer to use some kind of discriminating method to supervise and control its own products to improve the competitiveness of products in the market. According to the test results and the characteristics of the products for many years, the following score tables and discriminating methods are proposed; the cutting efficiency score FT and the durability score FG are measured by the average time and average consumption of the three cuts, respectively.


F = aFT + (1 a a) FG;

Ft: cutting efficiency score;

Fg: durability score;

The proportion of cutting efficiency in the total score, which ranges from 0 to 100%, means: only 100% is considered efficiency, regardless of the durability of the cutting piece; when taking 0, only the durability of the cutting piece is considered without considering the efficiency. . Under normal circumstances, when the section of the workpiece to be cut is large, such as a round steel with a diameter of 60 mm or more, the value of a is large. For example, when a round steel having a diameter of 20 mm or less is cut, the value of a may be small, and it is recommended to take 30% to 50%.

According to the above principles, the user selects the cutting and cutting piece to be economical and convenient to use. The cutting piece has to pass 60 points to pass.
Conclusion
There are a large number of domestic 5 inch resin cutting disc for metal cutting production enterprises, because it is industrial consumables, the market is large, suitable for entrepreneurship, but if you do not pay attention to quality, it will be eliminated in the competition. The production experience of the enterprise is very important. The theoretical guidance is fundamental. Blindly making the cutting piece manufacturing as cement sand and gravel will never work well. There is a basis for formula adjustment. If you do not form a relatively stable customer formula for a certain period of time, your product quality will never be stable. Quality problems, the right medicine, the medicine can be removed! The quality improvement of the resin cutting piece cutting piece, bearing in mind that the theory must be combined with the actual to be able to have vitality.
