Abstract
The influence of polycrystalline diamond particle size on the cutting performance and the wear mechanism of the cutting tool in the machining of high pressure laminated (HPL) flooring was investigated on a Liwei FXZ202 test rig, by brazing five types of SYNDITE polycrystalline diamonds (PCD) into one cutting tool for HPL flooring. The wear volume loss and the worn surface profile of the cutting tool at a certain linear cutting distance were determined with an optical microscope and a scanning electron microscope, respectively. The results showed that the cutting tool made of PCD with coarser diamond particles had better wear resistance than the one made of PCD with finer particles. The cutting tool was characterized by intercrystalline fracture attributed to the fatigue and partial cleavage fracture in the machining process. The cracks between the crystalline particles had a great effect on the wear resistance of the PCD cutting tool.
