When you need to perform OD grinding, you’ll probably be using a horizontal machine, and it’s important to get it right the first time. If not, you could be dealing with a lot of scrap material and delayed orders. Here are some of the most common factors that can affect the quality of your outside diameter grinding.
Grinding Wheel
If you use a wheel that’s not fine enough, you run the risk of scratching or marring the finish on your workpiece. Always check the wheel before you begin a new project and don’t assume it’s the right one.
Wheel Dressing
Dressing sticks can be used for cleaning, sharpening, and truing your OD grinding wheels. Dress grinding wheels quickly if you need to make fast cuts. This gives it a rougher finish. Make sure your dressing stick is in good condition. If you want to clean your wheel, move your dressing stick across the face in a back and forth motion. For polishing, you should use the dressing stick very slowly to give it a finer texture.
Materials
If you are trying to put a fine finish on a soft metal or material, it may take a while. In fact, harder metals are easier for fine finishing. Knowing this factor can help you plan your project more effectively.
Speed
If you are using a soft metal and you want a fine finish, try slowing down the feed rate. This can sometimes make a difference, and you might not have to change out the grinding wheel. On the other hand, speeding up the process can give you a coarser finish, if desired.
Coolant
Keep your coolant clean, and a good coolant recovery system can help to improve your quality and operating efficiency. Also, if you need help with your grinding projects, consider a trusted machine shop specializing in ID and OD grinding services.
