The tools diamond-cut considerably exceed the hardness and resistance of tools standard abrasives such as those made from corundum or silicon carbide.

For the manufacture of diamond blades, metal and synthetic diamond alloys are used, in percentage and appropriate granulometry to cut various materials such as concrete, asphalt, granite, marble, glass, ceramic, porcelain, among others.

When using professional cutting tools such as diamond discsOne of the most important aspects to consider is security. Due to their constitution and the work for which they are designed, jobs with diamond discs must be accompanied by the implementation of the corresponding security measures.

These measures are of vital importance both for the physical protection of the user and for the proper care of the discs. Likewise, these guarantee the proper execution of professional quality work.

In this note we will describe in detail the safety criteria that you must implement when cutting material with diamond discs.

Safety measures before starting work

  • You must carefully read the safety instructions provided by the manufacturer of the disc.
  • Do not allow the use of diamond cutting discs by people without proper instruction.
  • check the diamond blade to rule out any failure or damage that may increase during use. It is recommended to place the blade on the saw and rotate it for one minute before starting the cut, to check its adjustment.
  • Make sure that the selected disk is suitable for the task at hand.
  • Never use discs for dry cutting if wet cutting is indicated on the product.
  • You must use the diamond discs only on machines designed to work with them.
  • Never force the disc to place it in the machine, nor modify the size of the disc hub.
  • Verify that the maximum working speed indicated on the machine is less than or equal to the speed indicated on the disk.
  • Validate that the cutting machine is in good condition and clean.
  • Never use machines without a protective guard.
  • Check that the equipment to be used has the correct water and oil levels. You should also validate that the water pipes are not blocked.
  • Clean the adjusting flanges before placing the disc. The disc must respect the size of the flanges. You should not use unbalanced or vibrating discs.
  • You must verify that the diameter of the central hole of the disc corresponds to the diameter of the axis of the cutting machine.
  • Keeping the machine unplugged, attach the diamond cutting disc.
  • Make sure that the direction of rotation of the disk is the same as the direction of rotation of the cutting machine.
  • Check that the disc is properly centered and fixed to the machine.
  • Use protective equipment to make the cut. You must wear safety glasses, ear protection, dust mask, gloves and safety boots.
  • Do not turn on the machine if the disc is in contact with the piece to be cut.
  • Cutting tasks must be carried out in areas free of flammable materials.

Security measures during the execution of the work

  • The pressure on the disc during the cut must be soft, and it must be done respecting the back and forth movement.
  • Make breaks during the cutting work, to avoid excessive overheating of the disc.
  • Make the cut in a straight line. Never tilt the disk during the execution of the task, the diamond disc you should work at a 90 degree angle to the work piece.
  • You should make your cuts in long sections and in multiple runs, to allow the blade a chance to cool.
  • In the event that the disc becomes caked due to overheating or reduces its cutting power, you can recover it by cutting a calcareous stone or abrasive material, such as marble, tile or concrete.
  • Don’t make curved cuts with a straight flat blade.
  • Change the diamond blade if you notice any irregularity in it.

Security measures after the execution of the work

  • To transport the clipper, you must first unplug the clipper and remove the Diamond disk to avoid damage.
  • With the saw disconnected, remove the disc, store it safely and away from the reach of unauthorized persons for its use.
  • You must store the disc in a place free of humidity, and extreme temperatures.

Most common problems during the use of diamond blades

We indicate a series of problems that can arise during the cutting work with diamond discs, and recommended solutions for such issues.

voltage loss

Possible causes:

  • Low flow cooling
  • Using the disk at a higher speed than recommended
  • Use the disc at low speed
  • Overheat the drive

Recommended solutions:

  • Use enough coolant
  • Reduce disk speed
  • Use the speed recommended by the manufacturer
  • Validate that the disk is being used in the correct task

Glazed disc (diamonds buried in the alloy with very little or no exposure)

Possible causes:

  • Insufficient coolant flow
  • Bond too hard for cut material
  • Very high working speed
  • Low machine power

Recommended solutions:

  • Use enough coolant
  • Use a softer rubber
  • Slow down work
  • Check the power of the machine

Cracks in the body of the disc

Possible causes:

  • Very hard disc for the cut material
  • Inadequate coolant volume or use of wet-dry disc
  • Saw bearings in poor condition, discs with loss of tension
  • Too much cutting pressure or curved cuts
  • excessive RPM

Recommended solutions:

  • Use a diamond blade with a softer bond
  • Use enough coolant
  • Validate machine bearings
  • Reduce pressure on the cut
  • Make cuts at 90 degrees
  • Reduce RPM as recommended
Segmented diamond blade

Segmented diamond blade

Uneven segment wear

Possible causes:

  • insufficient cooling
  • Saw bearings in poor condition, motor in poor condition
  • misalignment

Recommended solutions:

  • Use enough coolant
  • Check the bearings and the motor of the machine
  • Check the alignment of the machine and the disc

Low shelf life

Possible causes:

  • Incorrectly selected disk
  • insufficient cooling
  • Saw bearings in poor condition, motor in poor condition
  • a lot of power
  • Very fast or very deep cuts

Recommended solutions:

  • Choosing the Right Disc for the Application
  • Use enough coolant
  • Check the bearings and the motor of the machine
  • Validate machine power
  • Make the cut smoother and with less depth

The disc does not cut

Possible causes:

  • Incorrectly selected disk (too hard)
  • insufficient power
  • glazed disk

Recommended solutions:

  • Choose a disc with a softer bond
  • Check the power of the saw
  • Validate the appropriate disc for your application

Taking into account this safety information when working with diamond blades, you will be able to prevent any type of accident, and carry out a professional job.
