Usually a synthetic material is now used. Carborundum is made from silicon carbide. A composite of silicon carbide and aluminum oxide is better.

In the days of the old windmills and water driven mills, for grinding cereal grains, a hard stone called millstone grit was used.

How do you shine granite?

This depends on what you mean by "shine granite". If your granite counter top looks dull and you're looking to bring it back to its original luster, you might want to look into some Dia-Glo diamond polishing compound, a felt wheel, a velcro backer pad, and a variable speed grinder. This is normally what professionals would use to "shine granite" back to its original luster after years of wear and tear. This can be done by someone that is not a professional if he or she is handy and has a good idea of what to do. I would not recommend this to someone who does not have proper instruction. There are DVDs for Fabricating Granite for the Do-It-Yourself out on the internet that will explain exactly how to do this, what you need, and what this type of job would require. If you're looking to take raw granite that has never been polished at all and "shine granite" then you're looking at an entirely different process. This process is also well documented with DVDs on Fabricating Stone for the Do-It-Yourselfer. This process takes a variable speed grinder, a set of about 8 diamond polishing pads, and a lot of elbow grease. There are many types of polishing pads for granite and other natural stones, but the general use of these and process of polishing is the same. If you are doing this I would also suggest contacting a professional or getting How to Granite DVDs to instruct you on the basics of this. The previous answer given about ager isn't necessarily to shine granite. Ager will restore the granite's luster to a point, but it's normally used for color variation matching. Imagine a sidewalk before it rains. Now imagine the sidewalk after it rains. The Ager will make your stone look like the sidewalk after it rains. It simply brings out the color. Honestly, without proper instruction I would not go about doing this myself. Either get an instructional DVD and learn about the process or hire a professional. On the other hand, working with stone isn't something that takes years to learn. It's just like working with any other product - a little practice and the right tools and you're all set!


What are the other four minerals are in granite?

Granite primarily consists of four main minerals: quartz, feldspar, biotite, and muscovite. In addition to these, other minerals that can be found in granite include hornblende, augite, and garnet. The specific mineral composition can vary based on the granite's origin and the geological conditions under which it formed. These minerals contribute to granite's overall strength and durability, making it a popular choice for construction and countertops.

Can I use my coffee grinder burr for grinding other foods?

Yes, you can use a coffee grinder for other foods and spices similar in texture such as salt, pepper, and other spices. It is important to clean out the grinder after each use though if you do use the grinder for multiple foods to ensure that the taste is not affected. You should not use the grinder for meat products either such as chicken, beef, or pork. Another precaution to take is that if during the course of grinding, you notice a strain or have to use excessive force, stop grinding and find an alternate source for your grinding needs.

What are the applications of CNC grinding?

CNC (computer numerical controlled) machines are computer controlled versions of precision machines. CNC grinding can be used to grind surfaces to precision based solely on computer instructions. CNC grinding is usually used for making tools. Computers are used to operate machines that grind metal to form shapes as specified by program of the computer. The tools are often used for the manufacture of other products (i.e., automobile parts, medical or aerospace equipment). An example of a simple tool formed by a CNC grinding is a drill bit. CNC grinding has many applications. Due to the ability to program complex instructions for the machines controlled by the computer, the possibilities are almost limitless. CNC shops manufacture items in small or large quantities ranging from simple to complex engineering depending on the needs of their customers.


Why does a bench grinder have two wheels?

A bench grinder has two wheels to provide versatility for various grinding tasks. Each wheel can have a different grit or type, allowing users to sharpen tools, grind metal, or shape materials depending on their needs. Additionally, using two wheels can enhance efficiency, as one wheel can be used for rough grinding while the other is reserved for finer finishing. This dual-wheel design helps achieve a smoother and more precise finish on workpieces.


What does a surface grinder do?
