Symptom:Uneven Diamond Segment Wear Cause: a.  Diamond Segments are worn on one side, reducing side, reducing side clearance. It is usually caused by misalignment of the saw or a lack of sufficient water on both sides of the diamond blade .            b .  Diamond Blade is worn out-of-round due to bad bearings, worn arbor or excessive dulling condition. See section on excessive wear. Remedy: a.Check saw alignment. Clean water system, making certain that water is properly applied to the leading edge of the blade flanges. Check to see if pump is supplying sufficient, even water.              b.Replace bearings or worn arbor as required Turbo segmented diamond blade

Factors Involving Concrete When cutting concrete , several factors influence your choice of diamond blades . Compressive strength Steel reinforcing (rebar) Hardness of the aggregate Green or cured concrete Size of the aggregate Abrasivity of the aggregate Type of sand The guidelines in this section are for general reference only. Your best source for information on the characteristics of the concrete you have to cut is from the original contractor. Contact your local Department of Transportation or City Hall for help in finding this information.   To be continued laser welded turbo diamond blade

Symptom:Undercutting Cause:Undercutting is a condition in which the steel center wears faster than the diamond segment, especially in the areas where the diamond segment and core are joined. The condition is caused by highly abrasive material grinding against the blade during the sawing operation. Usually materials containing sand are responsible for this condition, called segment loss. Remedy:The flow of swarf (abrasive cuttings) must be distributed over a wider area, away from the critical segment area with undercut retardant diamond segments or other types of undercut protectors specially positioned around the steel center to change the pattern of constant abrasion. Although successful in most cases, undercut protectors do not provide 100% protection. diamond blade for stone and concrete

Symptom: diamond blade core cracked Cause: a. diamond Blade is too hard for material being cut.             b.Excessive cutting pressure, or jamming or twisting the blade in the cut can cause the blade core to band or flex. When subjected to extreme stress and metal fatigue, the blade’s steel core will eventually crack.             c.Overheating through inadequate water supply or improper use of dry cutting blades. Remedy:a.Use correct diamond blade with softer bond.              b.The saw operator should use steady, even infeed pressure, and be careful not to twist or jam the blade in the cut.              c.Use adequate water to cool wet-cutting diamond blades (for example, 2-5 gallons per minute for concrete saws). Allow adequate airflow around dr...

Symptom:Excessive wear of diamond blade Cause:a.Using the wrong diamond blade on highly abrasive material (example: glazed tile blade on concrete block).           b.Lack of sufficient coolant to the blade. Often detected by excessive wear in the center of the segment (note: in both above cases, diamonds will usually be highly exposed).          c.Wearing out-of-round accelerates wear. Usually can be caused by bad bearings, worn shaft or using a blade too hard for the materials being cut.          d.Insufficient power caused by loose V-belts, inadequate voltage, or improper RPMs. Remedy:a.Consult the dealer or manufacturer for the proper blade specification for abrasive material.              b.Clean up water system. Make certain water pump is functioning properly.     ...

The application fields of vacuum brazed diamond tools 1. Suitable for DIY cutting in the western families,for it’s universal specialities. 2. Could use in strong cutting,drill,and expecially in the special spot like fire emergency,for the coherence and high convexity of diamonds. 3. Could cut the materials which is easily blocked like resin wind-power blade,ferrous metal materials,for its ample place for scraps 4. Cutting efficiently of concret which with high density of rebars,castiron pipe by government,two side rebars on the tracks high speed rail 5. For the super hard granites,ceramics and other materials which could not be easily cut by the electroplated/sintered diamond tools.
