    It's likely that you've heard the old saying, "The difference between men and boys is the cost of their toys." If you're an accomplished grinder, this saying can apply to your job as well. We'll discuss how to use your grinding tools effectively in this article, so read on and learn!


    Once you have the tool and your work area prepared, it's time to inspect your work piece. The purpose of this step is to ensure that your work piece is free of defects, such as chips or cracks, which can cause problems later on in grinding. You also need to make sure that all of the surfaces you'll be grinding are flat and level with each other so that they will sit flush against each other when finished. If any parts aren't flat or level, you may need to use a file or grinder during this step instead of a belt sander (this will require additional time).

    After inspecting the work piece for any imperfections, it's time now for inspection #2: inspection of both the wheel and machine itself. This step ensures that both components are in good working order before beginning grinding operations so nothing goes wrong during operation later down line! At this point also check whether there's enough room around where you'll be standing when using either device; if not then move items out by hand until there is enough room between them (this won't affect how well they operate).

    After completing these two inspections come lastly third inspection - inspection done specifically on belt sander itself before going ahead into process proper grinding one’s own materials: whether belts themselves

    Cutting Tools

    In the OD grinding process, the cutting tool is the most important part of the entire process. The quality and sharpness of your grinding wheel will directly affect how well you can cut your parts. When choosing a cutting tool, look for something that is:

    • Sharp
    • Cool to touch
    • Clean (Free from residual abrasive particles)

    Also be sure not to use any material that could damage your cutting tool such as stainless steel or cast iron.

    Wheel Speed

    The most important variable when setting up OD grinding is the wheel speed. The recommended value should be used as a starting point, but if it doesn't seem to be making a strong enough mark, try increasing it until you get the result you want. When adjusting the wheel speed, focus on the wheel itself rather than what's being ground on it—if you need to slow down or speed up your grinder, try moving further away from or closer to your workpiece. In general, higher speeds are better for removing material quickly and lower speeds are better for creating finer details in your workpiece; however, there isn't an exact science here (you may find that one works better than another depending on the situation) so experiment with various settings until you find what works best!

    Dress the Wheel

    Once the wheel has been polished, it must be dressed in order to remove any scratches and give it a nice smooth surface. This can be done with either sandpaper or grinding compound.

    If you want to dress your own wheels, we recommend using an 80 grit sandpaper that is designed specifically for this purpose. Make sure that you buy an orbital sander so that you don't damage your paint job! When dressing the wheel, start at one side of the rim and move from top to bottom in small circles until there are no visible imperfections on both sides of each spoke. Then move onto another spoke until all spokes have been dressed.

    A handy trick for knowing when your wheels are perfectly dressed: look at them straight on under bright light (or by holding them up against a window) without moving them around too much—if there are any visible scratches they'll show up as shiny spots where they aren't covered by dust or dirt yet (but if they do then just keep going!). If everything looks good then congratulations! You just saved yourself some money by doing this process yourself instead of sending out your tires 🙂

    Set the Work Piece

    The next step is to set the work piece at the correct height, angle and position. This can be done either manually or with a machine that automatically adjusts for these three items:

    • Work Piece Height - The optimum height for clamping your work piece is when it's about 1/8 inch from the grinding wheel. This will ensure that you get an even finish on your edge and not too much heat build-up in one area of your knife edge. You'll want to use a set of calipers to measure how far away from the wheel surface you want your knife edge to be on both sides when grinding.
    • Work Piece Angle - When using an OD grinder, it's important that you hold your knife at 90 degrees (perpendicular) against the grinding wheel so that all four sides of your knife receive equal amounts of material removal during each pass through this machine's cutting wheels or disks. If they don't, one side may become thicker than another while being ground by an uneven surface due to improper angles being used during initial sharpening attempts!

    Establish the Correct Contact Length, Force, and Feed Rate

    The first step in achieving a high-quality finish with OD grinding is to establish the correct contact length, force, and feed rate. They depend on several factors: the material being ground (job specific), the wheel speed (which you can find on our website), the wheel diameter, and the OD of your work piece.

    We recommend that you consult one of our expert distributors for assistance in determining what settings are best for your application.

    Follow these steps to succeed in OD grinding.

    • Step 1: Choose a diamond.
    • Step 2: Find the correct size diamond for your engagement ring and set it aside.
    • Step 3: Place your ring on an OD grinding plate (a round, flat surface used for spreading excess grit over the stone’s facets). You need to use a special tool called a handpiece to hold or place your diamond in place on top of this plate.
    • Step 4: Measure and mark where you want each facet to be ground off with a marker pen so that they are even all around the diamond’s perimeter. Do this by holding up your stone against a ruler or other straight edge while it is lying flat against one side of its grinding plate (or vice versa). Then use your marking tool to draw lines along each side of every facet so that you know where it should stop at its farthest edge when finished grinding all around its perimeter later on in this process.


    We hope this article helped you understand the steps involved in OD grinding. We’re confident that with a little practice, you can hone your skills and become an expert at this process!
