Experiencing excessive wear of the segment?

Potential Causes

Our Solution

  • Cutting at a speed too low for the job
  • Using the incorrect blade for the material
  • Insufficient cooling
  • Increase the rotation speed
  • Use a diamond stone cutting blade with a harder metal bond
  • Allow more cooling time
  • Double-check that the blade you’re using is correct for the material

Are your segments cracking?

Potential Causes

Our Solution

  • RPM is too high
  • Using the incorrect blade for the material
  • Overheating has caused excessive pressure, resulting in a crack
  • Reduce the rotation speed
  • Replace with a more suitable diamond blade for stone
  • Allow more cooling time between cuts and break during the cut if necessary

 

Is your segment no longer straight?

Potential Causes

Our Solution

  • This could be due to storing or transporting incorrectly
  • Ensure to store diamond blades (and all tooling and equipment) in a safe manner

Is your segment wearing unevenly?

Potential Causes

Our Solution

  • The machine shaft/bearings could be damaged
  • Improper use
  • Cooling is insufficient or is not being distributed laterally

 

  • Check the axial and radial clearance on the bearings of the shaft
  • Make sure that the blade is perpendicular to the direction you are cutting
  • Increase the air or water flow to ensure proper cooli

 

Is your blade body wearing unevenly?

Potential Causes

Our Solution

  • Abrasive fragments beating against the steel sides of the blade.
  • Incorrect blade for the material being cut
  • Incorrect RPM
  • Cooling is insufficient
  • Remove fragments where possible
  • Replace with a more suitable diamond blade for the material.
  • Adjust the rotational speed.
  • Increase the air or water flow to ensure proper cooling.

Is your blade body cracking or breaking?

Potential Causes

Our Solution

  • The impact at the start is too high
  • The RPM is too high
  • The blade has been stored incorrectly
  • Excessive twisting.
  • Cooling is Insufficient

 

  • Reduce the impact at the start.
  • Reduce the RPM
  • Ensure to store the blade safely
  • Make sure that the blade is perpendicular to the direction you are cutting
  • Increase the air or water flow to ensure proper cooling.

 

Are you experiencing and uneven rotation or loss of tension?

Potential Causes

Our Solution

  • The blade has been stored incorrectly
  • Excessive twisting
  • Cooling is Insufficient

 

  • Ensure to store the blade safely
  • Make sure that the blade is perpendicular to the direction you are cutting
  • Increase the air or water flow to ensure proper cooling

The bore is damaged or distorted?

Potential Causes

Our Solution

  • The Flanges are dirty
  • The Flanges have not been adequately tightened
  • Check the Flanges
  • Check that the blade is adequately fitted to the shaft of the machine.
