Properly sharpening and opening a diamond wire is crucial for maximizing cutting efficiency and tool life. If the diamond beads on a new wire are not opened correctly, the wire may become blunt, resulting in slow cutting or complete failure.
The first 2–3 hours of cutting are the most important to ensure the diamond wire performs optimally:
Start Slowly:
For a 55kW saw, begin with low speed and moderate tension for the first few minutes.
This helps the wire pass smoothly through corners without damaging the beads.
Increase Speed Gradually:
After initial startup, increase tension and speed to 26–28 m/s for the first 2–3 hours.
Maintain 85–90 amps to open the diamond beads efficiently.
Monitor Beads:
Stop the saw after about 1 hour to inspect the diamond beads.
Ensure they are opening correctly and in good condition.
⚠️ Incorrect settings of speed, tension, or amps can polish the diamond beads, reducing cutting efficiency. Excessive water canalso blunt the beads.
If the diamond beads become blunt due to improper operation, the wire can be reopened using one of the following methods:
Combine with a Used Opened Wire:
Connect the polished wire to a previously opened wire.
Ensure the bead diameter difference is no more than 0.5mm to avoid seizing in the slot.
Cut Concrete Blocks or Bricks:
Use the blunt wire to cut coarse materials like concrete to re-expose the diamonds.
Cut Coarse-Grained Sandstone:
Cutting sandstone can help reopen the diamond beads efficiently.
Use a Sandwheel Machine:
Manually dress the diamond wire on a sandwheel machine to restore sharpness.
Monitor the first cut carefully for the initial 2–3 hours.
Avoid excessive water flow during cutting.
Maintain correct linear speed and amps according to your saw and wire type.
Regularly inspect and dress the wire as needed to maintain cutting efficiency.
Following these procedures ensures your Keenova diamond wire saw delivers maximum speed, precision, and longevity.
