The secret of the grain

Fast and precise processing with significantly less noise. The new DT 900 US Special diamond cutting-off wheel from Klingspor makes this possible thanks to its special technology.

 

Noise is stress factor. If a table saw is screeching at over 100 decibels, for example, then it is unpleasant for the worker, even if they are wearing the prescribed ear protection. On construction sites in urban settings, especially near schools or hospitals, specific regulations regarding maximum noise levels are now in place. And since the issue of noise pollution protection is becoming increasingly important.optimised tools are needed.

 The diamond cutting-off wheel has been developed especially for table saws.

This is why Klingspor has extended its range with a special diamond cutting-off wheel. The DT 900 US Special ensures that noise pollution is more than halved compared to conventional discs, and the frequency is significantly more pleasant. This is made possible by the soundinsulating sandwich core. Frank Treichel, Market Segment Manager for Diamond Tools at Klingspor, reveals the secret. “Normally, our diamond cutting blades are made from a steel core onto which the diamond segments are lasered. With this disc, we take two steel cores that are slightly thinner, place a copper foil between them and laminate the whole thing. It's a bit like filling a Sandwich. “

Quiet thanks to a sandwich

Treichel demonstrates the difference by holding a disc between the thumb and index finger or one hand and lightly striking a spanner against it with the other hand. The conventional disc vibrates like a gong. The DT 900 US Special with the sandwich core only reproduces the tapping sound; the reverberation does not transfer. “In everyday working situations, this produces a significant noise reduction of more than 50 per cent”, says Treichel.

The first prototype series were tested in the UK. Many companies have specialised there in the sawing of clinker facing strips. “The worker saw strips out of stone all day long. The men have found tremendous relief with this new, quiet leaf,” reports Treichel. Using a noise-insulated disc also only makes sense on a table saw. Other machines make such loud motor noises that the disc itself can barely be heard anyway. On a table saw with an electric motor, a cutting-off wheel with a sandwich core is pleasantly quiet. In addition to its sound insulation, the DT 900 US Special has other advantages that make it attractive for users from the construction trade. These include the extremely broad spectrum of applications as well as the very high cutting speed thanks to short serrated segments. The DT 900 US Special also wins points with its especially clean and precise cutting. Among customers, the new, largeformat diamond cutting-off wheel is already in high demand. Not least because Klingspor attaches such great importance to high quality. Production in Europe makes the refined difference, adds Treichel. And anyone who witnesses the new, quiet discs in action will experience the famous wow effect with their own ears.
