Synthetic diamonds are being used more and more for producing dressing tools. On the one hand, the demands of the industry cannot be met with natural diamonds, and on the other, the requirements of process security and dimensional accuracy of the dressing tools is increased significantly. The biggest advantage of synthetic diamonds is their consistency. The materials used include MCD, CVD, and PCD. Their defined shape helps guarantee consistent and reproduceable quality for their entire life span. This enables use without altering dressing parameters and achieves constant grinding wheel topography.
PCD is mainly used as a triangular plate. These originally come from the internal grinding range, but in the meantime, they are also used for cylindrical grinding wheels. PCD is a polycrystalline diamond featuring a metallic binder phase. The advantage of this is that complex shapes are possible with PCD. This material is therefore recommended for special forms for dressing tools featuring highly complex grinding wheel profiles (e.g. based on an insert). We process top quality PCD featuring a polished surface for our DRESSO dressing tools. This significantly increases the tool lifetime versus conventional PCD material. Triangular plates are also available featuring CVD. This features an increased tool lifetime versus PCD. We offer re-grinding service for both models.
CVD is a polycrystalline, synthetic diamond. CVD is less subject to crumbling and use is directionally independent due to its polycrystalline structure (isotropic). It is therefore very well suited to difficult dressing tasks and features a high level of resistance. However, its properties make it extremely sensitive to heat. Therefore, the optimal feed of a sufficient quantity of coolant lubrication is required. In case this is not ensured for even just a moment, the entire CVD will burn up and will then be unusable or the tool lifetime will be severely reduced. For this reason, we also recommend a model of this tool featuring interior cooling. DRESSO CVD tools are especially recommended for CNC-controlled automatic grinding machines. Due to their defined geometry, they ensure consistently reproduceable and constant quantity for their entire life span up to complete use of the dressing tool.
MCD is a mono-crystalline, synthetic diamond. This involves a synthetic recreation of a natural diamond. Due to its crystal matrix structure, this material is directionally independent (anisotropic) as far as the lifetime of the diamonds during dressing is concerned. We therefore recommend setting the strands diagonally in order to achieve the maximum life span. A dressing tool featuring flat-positioned strands also features advantages nevertheless, and this should be preferred depending on the dressing task. DRESSO MCD tools are also very well suited to dressing ceramic bound CBN wheels. MCD is extremely sensitive to blows and heat. Therefore, careful handling and the optimal feed of a sufficient quantity of coolant lubrication is required. In case this is not ensured, the tool‘s lifetime could be diminished, it could be damaged, or it could become unusable. DRESSO MCD tools are especially recommended for CNC-controlled automatic grinding machines. Due to their defined geometry, they ensure consistently reproduceable and constant quantity for their entire life span up to complete use of the dressing tool.
MCD in the shape of a small stone (macle) was developed especially for manufacturing profile dressing tools. MCD makes it possible to ensure consistent and constant quality, and it is a good alternative to natural diamond. This opens up completely new options for manufacturing the end product that were often difficult and very expensive or impossible. MCD macles combine outstanding properties of synthetic mono-crystalline diamonds with the beneficial aspects of commercial effectiveness for the end user.
