When inspecting screws with gauge , microscopic chips left during machining may adhere to or weld to the gauge .
Screw gauge is manufactured with very strict tolerances, so if you continue to inspect the screw in that state, the street side gauge will not pass.
Also, once it is welded to the gauge , it cannot be removed and used.
In other words, gauge will not be able to make the right decisions.
This phenomenon is especially likely to occur with non-ferrous metal materials such as aluminum.
This new product "DLC-LG" is a DLC coating that does not easily react with aluminum, etc., to the gauge on the street side.
The most important feature is the DLC coating to prevent welding of non-ferrous metals.
DLC Coat, short for Diamond Like Carbon, is a coating with a very high hardness and smooth surface. It is mainly made of carbon.
In fact, carbon has the property of not reacting easily with aluminum, so together with the smoothness of the surface, it is designed to prevent welding of aluminum.
In addition, the "diamond-like" hard surface reduces gauge wear at the same time.
OSG has succeeded in creating innovative products by clearing strict gauge tolerances, including coating thickness control, with the grinding and coating technologies that it has cultivated over many years in the manufacture of cutting tools.
In particular, for customers who have many opportunities for gauge inspections in non-ferrous metal processing, DLC coatings are recommended because they can be expected to avoid unexpected gauge failures.
We hope you will find it useful for improving the field.
