common diamond blade problems

It is unavoidable to encounter a problem when using saw equipment and diamond blades, especially in rigorous projects. This is why it is crucial for people to know what to do when such problems occur.

To help with this dilemma, we listed down some of the common diamond blade issues that can occur when cutting, plus a list of potential solutions to fix the problem quickly:

Blade overheat

Cause: An overheated blade is a common problem usually encountered during a dry cutting. This happens when the adequate coolant isn’t sufficient to the diamond blade, causing the blade to quickly heat up because of the fraction.

Solution: Dry blades are only used for shallow cutting around 1 to inches deep, or what you call as step-cutting. If you encounter such problem during a wet cutting, make sure to check the water supply for adequate volume or check for any obstructions in the water system.

Loss of tension

Cause: Loss of tension on the blade can be caused by several things including a misaligned blade or wrong RPMs. It can happen if the blade is excessively hard for the material you are cutting, or when your blade flanges are not the same size in diameter.

Solution: The first thing you must to do is to check if the blade is aligned correctly. Make sure that you are using the right blade for the material you are cutting. Do also check if the blade has the correct blade collar diameter. When it comes to RPMs, you can use the tachometer to make sure that the blade shaft is running at the proper RPMs for the blade.

Excessive wear

Cause: Excessive wear happens when the segments of the blade are worn too quickly. This is caused if you use the blade on the wrong abrasive material, or if the blade lacks sufficient coolant. It can also be caused by bad bearings or worn shaft, or otherwise, insufficient power caused by improper RPMs or loose V-belts.

Solution: Make sure to use the proper blade specification for the abrasive material. When it comes to its coolant, see if the blade’s water pump is functioning properly. Check the diamond blade’s bearings and arbor, and make sure to tighten the belts tautly or replace it if it is worn out.

Segments loss

Cause: Segment loss happens when one or more segments of the blade happen to fall off the blade core. This is caused when the blade is too hard for the material that it is cutting. It can also occur if the blade flanges or arbor have worn out, or if the shaft bearings are bad.

Solution: To fix this, you need to switch to a softer bond. Or if it is the blade flanges that causes it, make sure to replace them. Check the arbor and bearings as well, and replace them if they are already worn out.

Non-permeating blade

Cause: If the blade is spinning in the cut but isn’t cutting the material then that poses a big problem. This happens if again, the blade is used to cut a harder material that it can’t handle or if there is insufficient power to permit the blade to cut properly. It can also happen if the blade has become dull because of its continuous use in hard and abrasive materials.

Solution: First thing first, inspect the blade and saw. Check if the belts are not loose and the saw is producing enough power for the cutting process, and that is running at the correct RPMs. You can also consult the dealer or your diamond tool supplier for the proper blade to use on your project.
