The Tangent And Inverse Tangent Of The Stone Block!

When I was engaged in stone production and processing in the 1990s, no one had ever received professional training in stone processing. Instead, I learned by myself in production practice, constantly summarized the problems encountered in the production process, received lessons from mistakes, and accumulated and enriched the knowledge of stone. Among them, the quasi-professional terms of tangent and inverse tangent in stone processing were only known after ten years, and the process was very long. In this article, we will talk about the tangent and inverse tangent of stone blocks.

China’s stone industry development from the ninety s, thirty years up to now, 30 years grew a lot of workers, but the stone industry professional aspects of systematic and theoretical education are very poor, with a systematic and theoretical talented person very few, because everyone is the master train an apprentice, accumulation of knowledge, stone or no division mode that knowledge is very limited, We need to accumulate more knowledge through more media and ways, reduce the learning process, and acquire more knowledge in the shortest time. After all, life is limited, but knowledge is boundless!

Although tangent, methods of the two stone processing terms to understand people is very simple, but I believe that understand the people is extremely limited because the people understand the term is associated with the term, these people often saw, gang saw, sand big slice material, even though these professionals, I think there are a lot of people do not necessarily know tangent, the methods of the term.

These practitioners who know “tangent”, “methods”, they were less because there’s almost didn’t see any books about stone professional knowledge in detail “tangent”, “methods” of professional terms if any, but because people read books, buy books has dropped, a thick book to find “tangent”, “Reverse cut” these four humble words are like looking for a needle in a haystack.

Among the many terms of stone knowledge, “tangent” and “inverse tangent” are basic and very important, which are the professional terms that stone people must know. If they don’t know these two basic terms, they are not qualified stone people. So what is a tangent and what is an Inverse tangent? To understand two basic terms, start with the concepts of “tangent” and “Inverse tangent”.

01. What is “tangent”?

“Tangent”, that is, along with the texture surface cut, also known as the cross-cut, that is, saw blade or saw blade sawing stone along the textured surface, the cut surface can see the regular complete texture. Many stone processing should pay special attention to tangential, tangential wrong, decorative surface texture difference is very large, greatly affect the decorative quality of the stone surface.

02. What is “negation”?

“Reverse cutting” is the vertical texture surface to cut, but also the vertical cutting, that is, saw blade or saw blade vertical texture surface saw cutting stone, the cut surface is random. If customers do not have special requirements, stone generally will not cut back. Marble after cutting because the surface texture difference is too big, usually with another name stone.

03. Tangent and inverse tangent direction and identification

Usually, when we carefully observe in work, we will see that there are three bars sprayed on the side of many blocks, as shown in red in Figure 1. Those who know this will know that this is the cutting direction of the “tangent” of blocks. When sawing the large plate and blank, it is ok to sawing in this direction. The reverse cut block generally has no mark, usually, we put the block on the turning machine, the “tangent” direction of rotation 90° Angle mounted trolley so that the saw out of the large plate surface is the “reverse cut” saw surface.

04. How to determine tangent and inverse section from block surface

Not all the blocks are marked with the tangential surface, especially some granite blocks when there is no mark tangential block to master this method and principle to find the block of the normal section: the texture is obvious, clear, uniform, stone surface fewer defects for texture surface; For some of the stone itself is disorderly grain, there is no clear sawing direction of the material, the choice of good face, stone defects, high rate of surface as the sawing direction. For some block surface with soil or long black surface, can’t see waste material, of stone material surface texture with high-pressure water gun clean dirt on the surface of the waste material and black material, wash not clean it with steel brush clean, identify the texture direction of the stone material surface, see the clear stone material surface texture, color, deciding the tangent plane of waste material.

Judging the sawing direction of the stone block without a target direction can be learned in more than one or two days because there are too many types of stone and the texture changes greatly. It takes a period of practice and exercises to reach the level of accurately judging the sawing direction of the block. Good this article to write here first, please pay attention to my mailbox
