Different diamond wires

Diamond wire type K

The diamond wire type K is a nickel-plated core wire with a low concentration of nickel-coated diamonds. The diamonds are extremely firmly bonded to the core wire via a galvanic process. The nickel bonding is resistant to corrosion and has a very high bonding or holding force and thus a long service life. This diamond wire is recommended for machining medium-hard to hard materials.

Attention: The abrasion of the thin nickel layer on the diamonds can be found after a cut in the cut material of the cutting gap and not in the cut workpiece - as is often falsely claimed.

Diamond wire type L

The diamond wire type L is a nickel-plated core wire with a high concentration of nickel-coated diamonds. The diamonds are extremely firmly bonded to the core wire via an electroplating process. The nickel bonding is resistant to corrosion and has a very high bonding or holding force and thus a long service life. This wire is an all-round wire and suitable for medium-hard to soft materials.

Attention: The abrasion of the thin nickel layer on the diamonds can be found after a cut in the cut material of the cutting gap and not in the cut workpiece - as is often falsely claimed.

Diamond wire type W

The diamond wire type W is a nickel-plated core wire with a high concentration of nickel-bonded but not nickel-coated diamonds. Using a special process, the diamonds are only partially embedded in the nickel layer of the core wire. The nickel bond is resistant to corrosion and has a good bonding or holding force and thus a long service life. This diamond wire is recommended, for example, for cutting plastics.

Diamond wire with pressed in diamonds

Diamond wires with diamonds pressed into a stainless steel wire are offered on the market as the super solution. No corrosion and no material entry of binder - such as nickel - into the workpiece to be cut.

The big disadvantage of these diamond wires is unfortunately the low bending strength due to the many notch effects and thus the short service life. Why it is? The pressing of the diamonds into the core wire creates press-in points which cause notch effects. Since the diamond wire is exposed to constant bending interactions during sawing, these notches lead to premature breakage of the diamond wire. In addition, pressed-in diamonds do not have the bonding or holding power as, for example, nickel-coated diamond wires.

If the diamonds are not pressed at least 50% into the core wire, they will be pressed out of the wire after only a few seconds of the cutting process. This reduces the concentration of the diamond coating, which results in a reduction of the cutting feed, since otherwise the remaining diamonds in the core wire would have to absorb even higher cutting forces.
