ICT offer of dressing wheels include rotary diamond dressers and diamond form rolls with excellent performances.
The rotary diamond dressers shape grinding wheels in the shortest possible time. Their features are:
- Profiling grinding wheels in one step through plunge grinding;
- Profiling from the simplest work piece to the most complicated shape;
- Meeting exact precision demands.
The diamond form rolls shape grinding wheels in automatically controlled CNC dressing operations. Their main features are:
- Profiling grinding wheels by moving the diamond form roll along the required contour;
- Profiling from the simplest work piece to the most complicated shape;
- Meeting exact precision demands;
- Offering high economic efficiency.
Dressing tools are of different types.
Type NZ (randomly distributed diamonds), type NS (hand set diamonds) and type NM (hand set / randomly distributed diamonds) are produced by reverse plating method. In them diamond grain is actively involved in the dressing action, leading to long service life. These types of rolls are used for intricate profiles and tighter tolerances. NZ type dominates in application of almost all types of profiles, especially where surface finish is important. NM type is preferred where work pieces are prone to grinding burn.
Type IZ (randomly distributed diamonds) and type IS (hand set diamonds) are produced by infiltration in the reverse method.
They can meet critical tolerance levels. IZ type tools, depending on the profile, ensures shorter manufacturing cycles. The IS type is particularly suitable for profiles with intricate links that cannot be produced by reverse plated method. Both IZ and IS types are extremely robust in construction.
Type PM (diamonds randomly distributed) are produced by direct plating.
Due to random distribution of abrasive grits, the surface of the rotary dresser is relatively rough and uneven. These tools are therefore extremely aggressive and achieve rougher surface finish. Thus they are not suitable for applications that call for high accuracies. The body can be recoated more than once, contributing to economic efficiency of the tool. Also their manufacturing cost is relatively low.
Finally type SM (diamonds interspersed) are produced by sintering, using mixture of diamond and bond.
While the grit size equals the thickness of the coating in all types of abrasive tools, only in this type it is possible to obtain thickness in multiples of the grit size. Thicknesses of 2, 3 or 5 mm are standard. Since these types of dressers cannot be produced to a high degree of accuracy, they are ideal for simple profiles.
