Diamond Tool Dressing Procedure
- Soak dressing stick or block in coolant.
- Turn off coolant supply to diamond tool.
- Turn on diamond tool and allow to reach full-speed.
- Turn off diamond tool.
- Apply dressing stick to coasting diamond tool or in the case of core drills, lower bit into dressing block with enough pressure to slowly bring to a complete stop.
- Repeat if necessary
Blade Troubleshooting
Blade Worn Out of Round
Causes:
- Shaft bearings are worn
- Blade arbor is damaged from previous improper mounting
Remedy:
- Install new blade shaft as required
- Replace worn shaft or mount an arbor reducer
Blade Will Not Cut
Causes:
- The bond is too hard for the material being cut
- Blade has become dull (glazed) as a result of being used on too hard of a material
- Machine has insufficient horsepower
- Cutting is slow
Remedy:
- Use a blade with a softer bond
- Glazed blades can be re-opened by cutting a soft, abrasive material such as concrete
- Change to a lower horsepower blade
Uneven Segment Wear
Causes:
- Insufficient water (usually on one side of the blade)
- Equipment defects cause the segments to wear unevenly
- Saw is improperly aligned
Remedy:
- Flush out water system and check flow and distribution to both sides of the blade
- Replace bad bearings, worn arbor or misalignment to the spindle
- Check saw head aligned for squareness both vertically and horizontally
Arbor Hole Out of Round
Causes:
- Blade collar is not tightened, allowing blade rotation or vibration of shaft
- Blade collar is not tightened, allowing blade cramping
- Blade is not properly mounted
Remedy:
- Tighten the shaft nut with your wrench to make certain the blade is adequately secured
- Clean blade collars, making certain they are note worn
- Make sure the blade is mounted on the proper shaft diameter before tightening the shaft nut
Segment Cracks
Causes:
- The bond is too hard for the material being cut
Remedy:
- Use blade with softer bond
Blade Wobbles
Causes:
- Blade is running at improper speed
- Blade collar diameters are not identical
- Blade is bent as a result of dropping or twisting
Remedy:
- Make certain the blade shaft is running at the recommended RPM to match tensioned speed of the blade
- Check blade collars to make sure they are clean, flat, and the correct diameter
- Get a new blade or have the blade retensioned
Segment Loss
Causes:
- Overheating due to lack of water
- Steel center is worn from undercutting
- Defective blade collars are causing improper blade alignment
- Bond is too hard for material being cut
- Blade is cutting out of round, causing a pounding motion
- Improper blade tension
Remedy:
- Check water feed lines and make sure water flow is adequate on both sides
- Use sufficient water to flush out the cut
- Clean blade collars or replace
- Use a blade with a softer bond
- Replace worn bearing
- Ensure blade is running at a correct RPM and that the blade is tensioned for correct RPM.
Cracks in Steel Center
Causes:
- Blade flutters during cutting as a result of losing tension
- Blade specification is too hard for the material being cut
- Bad blade shaft bearing
- Steel center has been overheating as a result of blade spinning on arbor
Remedy:
- Tighten the shaft nut and have the blade retensioned
- Use softer bond to eliminate stress which created cracks
- Replace bad shaft bearing
- Check water flow, distribution and lines, and makes sure to tighten blade shaft nut.
Loss of Tension
Causes:
- Steel center has been overheating from rubbing the side of the material being cut
- Unequal pressure at the blade clamping collars
- Bond is too hard for material being cut
Remedy:
- Make certain the blade RPM is correct so the blade operates at its tensioned speed
- Blade clamping collars must be identical in diameter and the recommended size
- Use a blade with a softer bond
