Cutting Speed Comparable data between Conventional diamond blades and Arix diamond blades Arix diamond blade 1. Cutting Speed of Conventional diamond blades:around 2m/min 2. Cutting Speed of Arix diamond blades:around 3m/min The concepts of cutting speed and tool life have always had an inverse relationship among conventional diamond tools . Increasing the cutting speed leads to a drop in tool life and vice versa. Many diamond tool manufacturers have tried to improve the performance of a diamond blade by revising the diamond particle distribution to counteract this relationship, since it is known that the cutting efficiency of diamond particles in the segment of the blade is dependant on the distribution of inter-particle distance. Up till now all have failed. With JDR's ARIX or Arranged diamond technology , it is possible to maintain 100% control over inter-particle distance during segment manufacture.The result is that both tool life and cutting  efficiency are...

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.     ...

Symptom: Diamond blade won't cut Cause:a. Diamond Blade is too hard for materials being cut (examples: block or general purpose blade being used for extended period on hard brick. Asphalt diamond blade being used to cut hard concrete).          b. Insufficient power to permit diamond blade to cut properly (loose V-belts, low voltage, motor lacks horsepower).         c.  diamond Blade has become dull because of continuous use on fairly hard or vitrified material.         d.  Diamond Blade segments appear to still have plenty of life, but diamond blade won’t cut. Remedy: a. Consult dealer or manufacturer for proper diamond blade to cut materials on job.                b. Check belts, voltage, horsepower.               c. Dress with abrasive material until ...

Symptom:Overheated Cause: Adequate coolant was not provided. Remedy:Check the water supply for adequate volume and for obstructions in the water system. Use dry blades ONLY for shallow cutting (1-2” deep) or step cutting. Allow blade to run freely every 10 to 15 seconds in order to increase cooling air flow.

Symptom:Eccentricity Cause:The diamond saw blade shaft may have a groove scored in it, caused by a diamond blade spinning between the flanges. A new diamond blade, installed on the arbor shaft, will seat into the groove, and immediately run eccentrically when the saw starts. Remedy:Replace worn shaft. Diamond saw blade

Sympton:Eccentricity Cause:The bond is too hard for the material being cut. The hard bond retains the diamonds, and they begin to round off, causing the diamond blade to become dull. Instead of cutting, the diamond blade begins to “pound,” causing the blade to wear out-of-round. Remedy:Change to a softer bond, which will wear away more readily allowing the dull diamonds to be released and sharp, new cutting edges to become exposed.  granite cutting blade

Symptom: Diamond segment Cracked Cause: Diamond Blade is too hard for material being cut. Remedy:Use correct blade with softer bond system.  Granite cutting blade

Symptom: Diamond segment Loss Cause:Overheating can usually be detected by blue color on steel center and generally confined to the area where the segment was lost. Remedy:Check the water system for blocked water passages. Test pump to see if it is functioning. For dry cutting, it may be necessary to make shallower cuts and allow the blade to run freely every few minutes in order to let the air cool it. Diamond segment

Symptom:Eccentricity Cause:If the diamond blade shaft bearings are worn, the shaft and mandrel will run eccentrically, causing the blade to wear out-of-round. This happens most often with concrete saws when proper lubrication of the bearings is neglected. Remedy:Install new diamond blade shaft bearings. In some cases it might also be necessary to replace the blade shaft if it is worn or out of alignment. Diamond blade

Symptom: Diamond segment loss Cause:Worn diamond blade flanges fail to provide proper support and cause the blade to deflect. Remedy:Replace both blade flanges. Hot pressed diamond blade

Symptom:Loss of tension of diamond blade Cause: Diamond Blade improperly mounted on arbor shoulder becomes bent when flanges are tightened. Remedy:Hold diamond blade securely on arbor shoulder until outside flange and nut are firmly tightened. laser welded diamond blade

Symptom:Loss Tesin of diamond blade Cause:Diamond Blade being used at improper RPM. Remedy:Make certain diamond blade shaft is turning at the proper RPM by using a tachometer. This is especially important with concrete saws. Turbo diamond blade

Symptom: Loss Tension of diamond blade Cause:Utilizing diamond blade flanges that are under size or not the same diameter, creating uneven pressure on the center. Remedy:Make certain diamond blade flanges are proper size and identical diameter, minimum 3-7/8”, 4-1/2” on concrete saws, 6” minimum on diamond blades that are 30” diameter and larger.
