Multipoint and multigrain dressing tools

INEXPENSIVE, FAST AND ROBUST:
MULTIGRAIN BRINGS ADDED VALUE

Multigrain dressers, multigrain-, multipoint- and needle tiles are the economical solution when it comes to efficient removal at higher feed rates. The simultaneous engagement of several diamonds distributes the stress  –  this enables long service lives even at higher loads. Another advantage is the insensitivity to shocks or bumps. We produce multigrain dressers / multigrain- multipoint- und needle tiles and, on request, optimize dimensions, grit size, and binding individually to our customer‘s requirements.

APPLICATIONS:

  • Single-profile dressing of straight and even grinding wheel surfaces
  • Rough dressing
  • Fast dressing without scoring
  • Correction of imbalances

 

ADVANTAGES OF BAYER DIAMONDS:

  • Multigrain dressers and needle tiles are set in one ply from D601 upwards and the remaining diamonds are mixed with sintered metal powder. Below D601 the diamonds are only mixed.
  • Economical universal solution thanks to small carats of individual diamonds
  • Sintered bonds are matched to applications

ADVANTAGES OF MULTIGRAIN DRESSERS AND TILES:

  • Larger feed rate possible, since several diamonds are engaged simultaneously, thus transferring the work load to many diamond tips. This results in a faster dressing of the grinding wheel.
  • Multigrain dressers are very low-wear, so there is no need for readjustment except for occasional turning.
  • Economical method of dressing.
  • Also suitable for large grinding wheel diameters

 

ADVANTAGES OF MULTIPOINT- AND NEEDLE Tiles

  • Due to the single-ply set grain / needles the dressing of a sharp edge is possible.
  • Economical method of dressing.
  • Can be used up completely.

 

ADVANTAGES OF MULTIPOINT TILES:

  • The dressing surface is always sharp due to many small diamonds

 

ADVANTAGES OF NEDLE TILES:

  • The use of elongated diamond needles provide good stability

GRIT SIZES

Diamonds of selected quality are set by hand in several layers and held together with a sinter bond that is adapted to the application. Alternatively, diamond powder or diamond grit is sintered to form a dressing element.

We use grit sizes from D46 (0.05 mm) to D1181 (1.2 mm).

The designation D46 or D1181 stands for the mesh size in microns of the sorting grids used to determine the size of the diamonds.
