As far as the quality and accuracy of racks are concerned, currently the most common ones in China are YYC in Taiwan, KHK in Japan, Atlanta in Germany, Henrian in Germany, GUDEL in Switzerland, and relatively speaking, Taiwan. YYC's price is the best. Accuracy: Japan's KHK and Switzerland's GUDEL responded best to many manufacturers, followed by Taiwan's YYC, then Germany's Atlanta and Henryn (WHM), but KHK rarely made large modular racks, so In terms of large module racks, it is mainly YYC and Atlanta, YYC entered the Chinese market relatively late, so the visibility is not as good as the German brand, but reflected in the more used companies, quite good. Whether it is the delivery period or price, quality!
The precision of the rack is generally referred to as the error between the teeth. The smaller the error, the higher the accuracy. In general, the measuring method used by racks in Germany and Taiwan is the error amount per 300 mm. As for the accuracy standard, there are many more. International Standard (ISO) \ German Standard (DIN) \ Japanese Standard (JIS) \ Chinese Standard (GB). This is currently the most commonly encountered in China. Generally, Taiwan's racks will use the DIN standard, and Japan in addition to JIS standards. There is a KHK own standard. In general, the smaller the number of precision grades, the higher the precision, such as: JIS level 1 \ JIS level 2 \ JIS level 3, etc., JIS level higher than the second \ 3 level. The same , DIN5 \ DIN6 \ DIN7 \ DIN8 \ is the same reason. As for the conversion of precision in various countries, in fact, from their error can be roughly replaced, such as: JIS level 2 is equivalent to about DIN6 level \ ISO5 level;
