On the other hand, a finer grit CBN wheel, such as 220 or 400 grit, is ideal for edge maintenance and sharpening. If you’re looking to produce a mirror-like finish on your lathe tools, then a high grit CBN wheel, like 1000 grit, is the way to go. Overall, choosing the right grit size for your CBN wheel can make the difference between a well-groomed and efficient lathe tool or a worn-down, ineffective one.
So, consider the task at hand, and select the grit size that best suits your needs.
Coarse Grits for Heavy Stock Removal
When it comes to heavy stock removal, coarse grits are the way to go. These grits are characterized by their larger particles, which provide more aggressive cutting action. Commonly used grit sizes for coarse grits range from 12 to 3
Coarse grits are especially useful for leveling surfaces, removing deep scratches, and shaping materials. They are typically used on harder materials such as metal, stone, and fiberglass. Although coarse grits may leave a rough surface, they are often followed by finer grits to achieve a smoother finish.
Remember, it’s always important to match the grit size to the job at hand. Using too fine of a grit for heavy stock removal can be time-consuming and cause unnecessary wear on the abrasive material. So, if you’re faced with a tough material and need to remove a lot of stock quickly, reach for a coarse grit abrasive!
Medium Grits for General Purpose Grinding
When it comes to grinding, using the right grit size for your project is essential. For general-purpose grinding, medium grits are often the way to go. Medium grits typically fall in the range of 60 to 100 grit and are versatile enough to tackle a range of materials.
They can be used to remove light burrs, smooth rough edges, and prepare surfaces for further processing. Think of them as the Goldilocks of grit sizes – not too coarse, not too fine, but just right for many applications. However, it’s important to remember that grit size is just one factor to consider when choosing a grinding wheel or abrasive belt.
Other factors like abrasive material, hardness, and bond type can also play a role in determining the best option for your project. So before you get to grinding, take the time to research and choose the right tools for the job.
Fine Grits for Finishing
Fine grits are incredibly useful when it comes to finishing surfaces and achieving a polished look. These grits come in a variety of sizes, and it’s important to choose the right one for the job. Generally, the finer the grit, the smoother the finish.
Typically, a grit size of 240 or higher is considered fine and is great for finishing materials such as wood, metal, and plastic. When using a fine grit, it’s important to take your time and work slowly, letting the abrasive do the work. This will help ensure that you achieve the smoothest finish possible without causing damage to the surface.
It’s important to use the correct grit size for the job as well. Using a grit that is too fine or too coarse can result in a poor finish or even damage to the surface. Ultimately, selecting the right grit for the task at hand will go a long way in achieving a high-quality finish.
