Problems cutting with diamond wire?

? Here we explain how to solve the most common problems that can occur when cutting with diamond wire for stone or construction.

WHAT WE OBSERVE
IN THE DIAMOND WIRE
POSSIBLE CAUSESOLUTION
BOND DISPLACEMENT
– High thread tension
– Very little cooling
– Wire slides on the pulley matrix due to lack of adhesion
– Sudden wire lock
– Reduce forward speed
– Increase cooling
– Increase tension
– Use wedges to avoid closing of the cutting area
EXCESSIVE CONICITY

– Using of a suitable bead
– Increase peripheral speed and reduce forward speed
– Increase cooling
– Increase the profile speed
– Switch to a mode of cyclic drilling
– Abrasive Materials
– Small cutting surface
– Low / incorrect cooling
– Low peripheral speed
THE WIRE DOES NOT START THE CUT
– High tension of the wire
– Very pronounced corners
– Differences in diameter along the wire
– High contact arc
– Reduce forward speed
– Round corners
– Only use threads with ø with differences not exceeding 0.2mm
.
– Use guide pulleys
WIRE FLATTENED

– Insufficient number of turns per meter
– Excessive tension in wire
– Low cooling
– Insufficient distance between the pulley and the cutting area
– Increase the number of twist/ turns
– Reduce forward speed
– Increase cooling
– Increase distance
THE WIRE DOES NOT CUT OR CUTS VERY SLOW

– Very hard materials
– Very large cutting surface
– High peripheral speed
– Highly reinforced concrete
– Reopen with abrasive materials and / or reduce peripheral
speed
– Reduce cutting surface using guide pulleys
– Reduce peripheral speed
– Use appropriate alloy
WIRE BREAK
– High tension of the wire
– Very pronounced corners
– Pronounced arc at the entrance of the cut
– Strong vibrations at the conection
– Reduce forward speed
– Round corners
– Increase cooling
– Check balance and wear of the pulleys
CONNECTOR AREA LOSE
– Incorrect pressing or improper splicing
– High tension of the wire
– Very pronounced corners
– Pronounced arch at the cutting entrance
– Use the correct press and connector
– Reduce forward speed
– Round corners
– Use guide pulleys
DIAMOND IN BEAD
(A) EXPOSED

(B) SATIN
PERIPHERAL SPEED
(A) Increase the speed
(B) Low the speed
COOLING / ADVANCE OF THE MACHINE
(A) Lack of water / Increase speed
(B) Too much water / Reduce speed
