DIAMOND CUTTING BLADES

Diamondtipped tools are ideal for quick, clean machining (drilling,cutting) of any type of building material or natural construction-gradestone, with substantial cost and time reductions, especiallyuseful for small applications.

Thetype of tools has two parts: the diamond blade and the steelshank connected together with an attaching segment.

Theblade is made of a mix of metal powder/diamond granule mix.The cold-pressed mix yields a slug (of variable form) whichmust then be sintered (heated and pressed). The result isan alloy with varying mechanical characteristics. Thereare many types of segment and blade, with continuous orturbo rim.

Theshank is made of high grade steel, with a low carbon contentif used for laser welded tools.

Theattaching segment between the blade and the shank is obtainedwith various technologies:

Brazed: a silver alloy braze joins the parts without welding.This is only suitable for water-cooled cutting applications.Dry cutting is unsuitable for tools of less than 4 mm. jointthickness.

Laser welded: welds the parts togheter using a laser. Thisallows for safe use of segmented tools
for dry cutting.

Sintered: the powder mix is cold-pressed directly onto theshank. The successive sintering in
moulds yields continuous or segmented rim disks, with smoothor turbo segments. Allows for safe
use of the tool for dry cutting.

Afterthe joint has been obtained the diamond blade must be groundaccording to its cutting direction.

Thetool is then straightened and pre-stessed to ensure perfectlyrectilinear rotation without vibra-tion
at the cutting speed.
