Depending on the size of the diamond particles and different distributions in the pen, diamond pen into a chain, layered, arrayed and powdery several. Strong force from the days of using a combination of alloys as binder, the use of diamond particles not falling, until exhausted without intermediate grinding.
② rolling wheel dressing method
Rolling method wheel dressing, concrete cutting wheels speed by deceleration to 1 ~ 2m / s driven rolling wheel (made of metal, made of cemented carbide or abrasive) rotation.
Rolling wheels added to a pressure of about 3 ~ 5MPa the wheel, abrasive grinding wheel surface crushed or abrasive grains fall off. Rolling wheel dressing cutting method is better, lower cost, but is coarser grind the workpiece surface roughness, rolling tile cutting wheel wear, life is short, easy to lose precision. Therefore, this method is mainly used for trimming small quantities, less demanding precision profile grinding.
Trimmed wheel hardness uniformity is better, otherwise the wheel will produce local shape distortion.
