Flanges not properly tightened, allowing the blade to either rotate or vibrate on the spindle. Tighten spindle nut.
Worn bent, or deformed flanges. Replace parts.
Eccentricity
Shaft bearing is worn. Replaceshaft bearing
Blade arbor hole is larger than spindle shaft. Replace shaft or install a blade with correct arbor hole.
Cracked Blade Core
Operator using excessive feed rate. Use better technique, don't crowd blade.
Spindle rotation speed too high. Adjust speed.
Material is too hard for bond type. Use a softer, free cutting blade. loss of Side Clearance
Uneven segment wear. Insufficient water, generally on one side of blade. Be certain water is being adequatelyand equally distributed.
Equipment defect, causing the blade to wear out of round. Replace bad bearing, worn machine spindle, or re-align spindle.
Saw head misaligned. Check saw head alignment for vertical and horizontal squareness.
Segment Loss
Steel Cores cut thin due to under(rutting. Use sufficient water to clean slurry from cut.
Excessive heat. Lack of coolant, use more water and don't crowd blade.
Cracked or chipped segment
Jamming or excessive feed against embedded steel. Allow blade co penetrate steel at its own rate.
Undercutting
Diamond blades used to saw abrasive materials, such as green concrete and asphalt, are susceptible to 3 premature wear called “undercutting." Undercutting is caused by abrasive slurry wearing away the steel blade core.
Insufficient coolant.Check coolant and adjust as necessary. Blade being run in base material. Run blade on to depth of material being cut.
Blade will not cut Blade dull from cutting too hard materialor lacks enough abrasiveness to allow a controlled matrix erosion. Dress or sharpen blade with mortar material. If problem continues consult specification chart for softer blade specification.
Insufficient power or RPM. Check blade specifications and match to horsepower, tighten machine drive belts, and check RPM.
Problem: Short Blade Life
Using wrong blade on wrong material. Blade hardnesses are formulated for cutting specific materials.
Inadequate Coolant. Make sure water hoses are clean and free from blockages. Use Approximately 25 gallons per minute.
Bad spindle bearing& worn blade arbor, or misaligned machine spindle. Replace affected pares.
Low power from loose drive belts. Tighten belts to manufacturer requirements or replace worn belts.
Forcing the blade into deep cuts without cooling time (dry blades). Maintain high RPM and make a series of shallow cuts instead of one deep cut.
