good grinding performance, good surface quality
2015-04-15 by bridge
Since the CBN abrasive grains can maintain long-term micro-edge sharpness, will be processed workpiece machining accuracy and surface roughness values have reached more satisfactory results, and therefore can improve the durability of the workpiece 10% -30% . concrete cutting disc So even if the batch processing of the workpiece, the shape will always get higher accuracy and consistency. CBN grinding wheel to achieve high dimensional accuracy and low surface roughness, surface cracks and burns easily, a small residual stress. Improved surface quality, generally no cracks, high quality disc, and the residual stress can be obtained, significantly improve the fatigue strength of the workpiece, generally, the durability of the workpiece to be ground can be increased by 30-50%.

6, wear resistance, long life
CBN grinding wheel ratio up to 3500-5500, a hundred times higher than normal corundum grinding wheels, diamond grinding higher than 3-5 times.
7, environmental pollution, energy saving
Without too much powder dust.
8, high efficiency, good overall economic efficiency
Grinding sharp, small grinding force, CBN grinding wheel dressing long period, less the amount of dressing, long replacement time; long life cycle, grinding ratio, getting a better economy, use good shape retention, without regular Replace the wheel and wheel dressing, saving time and improving working conditions conducive to machining grinding discs operations.
CBN is not suitable for grinding hard alloy and non-metallic materials. Grinding at a high temperature, CBN case of alkaline aqueous chemical reaction occurs, CBN wheel at 300 ℃ alkaline solution are decomposed in boiling water can trace decomposition results crystalline grains will be destroyed, so the grinding only use oil-based coolant, not water-based coolant.
