The Silicon Carbide Grinding Stone Uses

Silicon carbide grinding stones are designed to sharpen, deburr, and handle overall grinding purposes. They are typically used to remove excess glaze & stilt marks, create sharp edges, and engrave on a glass. Compared to aluminum oxide points, they are incredibly tougher. This is because they are made, in particular, to be used on hard materials such as ceramics and glass. Let’s delve more into the silicon carbide grinding stone uses.

Silicon Carbide Abrasive

Silicon carbide, generally, is a unique ceramic material characterized by outstanding hardness. The only materials with better hardness compared to silicon carbide are cubic boron nitride, diamond, and boron carbide. 

It’s an abrasive from the combination of silicon and carbon. Abrasive experts show that the material is extremely abrasion-resistant and relatively more cost-effective as far as production is concerned. Silicon carbide is lightweight, features great thermal conductivity, and comes with low thermal expansion. Due to these, it’s a material usually applied as a solid or loose abrasive material in numerous applications. 

Silicon Carbide Stone

Have you heard of the term “carborundum stone?” If you haven’t, it may imply that you’ve not been sharpening your blades for quite a time. 

In this present decade, this stone is hardly called carborundum because most people refer to it as silicon carbide stones.

Silicon Carbide (SiC.) is a binary compound of silicon and carbon. One of the common and popular types of this stone is Sharp Pebble 400/1000 grit whetstone. This stone is perfect when it comes to repairing blades with damaged edges or giving tools an excellent sharpening process.

As for color, the stone can be gray/black or green. For instance, Sharp Pebble 400/1000 Grit sharpening stone is designed with green silicon carbide. Most times, operators use silicon carbide stones for sharpening knives produced from tough stainless steel due to its quality of cutting aggressively.

Silicon Carbide Grinding

Silicon carbide theoretically is not different from stone abrasive and diamond grinding. The material features progressive textures (60-1000 grit). It’s designed to be used by operators in a progressive way to achieve the most preferable and best finish. 

Nevertheless, there is a limitation in its ability to get rid of scratches and restore the high polish state of the stone. It’s virtually non-existent for removing lippage. Nonetheless, it remains an economical, moderate, and effective way of restoring a specific work piece.

Out of the three grinding methods, including grinding with diamond, stone abrasives, and silicon carbide disk, the first two methods ensure that stones are finished using buffing compounds, chemicals, or metallic elements.  Unlike these two methods, the silicon carbide disks cannot offer excellent results on granites but can thrive on travertines and marbles. Aside from using diamond and stone abrasives, silicon carbide disks also work effectively to provide desired sharpness by grinding damaged stones properly.
