Sharpening stone Sungari on an aluminum blank Apex 152x25x6 mm - ID 105

A block from the breed of Songhua (Sungari) with a working surface of 150x25 mm is designed for use in sharpening machines such as Apex or in sharpeners with a rotary mechanism. Sungari is a finishing block of dense sandstone, very dense in structure, close in type of impact to alumoceramics. But unlike ceramic bars, Sungari is quite easy to finish on silicon carbide powders, making it possible to get a perfect in many ways a unique offer for sharpening. Sungari is an ideal stone for work on abrasive suspensions and pastes. It does not give its suspension during work, and the high density of the rock structure does not allow third-party grain to sharpen surface rocks, therefore, changing the grain size of a free abrasive to Sungari, you can go through almost all stages of grinding from peeling to finishing. It is recommended to use abrasive pastes and suspensions comparable to the hardness of the stone itself - synthetic ones made of electro- and ceramic corundum or silicon dioxide based on natural abrasives. Using, for example, abrasive slurries from HLAD’Stone, you can go through the entire grinding stage from 400 grit to ultra-fine finishing, working on free grain on one stone. This sharpening option allows you to handle much harder steels than on synthetic stones with bonded abrasive. Such pastes will not affect the geometric parameters of the stone, unlike abrasives based on diamonds, elbor, silicon carbide, etc. In addition to the possible work on various kinds of induced suspensions, Sungari, in and of itself, does an excellent job of ultrafine finishing finishing of products from almost any steel. It can be used with both water and oil. The breed of Surgani is not hygroscopic, therefore, water and then oil can be used sequentially, changing the degree of abrasive effect on the workpiece.
