5. The grinding wheel has minimal wear but tends to accumulate debris and clog easily
Features: Ordinary grinding wheels wear out as they grind, while CBN barely wears. However, poor chip removal can easily lead to micro-pore clogging and subsequent gradual heating.
6. Significant fluctuations in dimensional stability
For the first time using the machine tool, fixtures, and thermal deformation are all being readjusted. The dimensions may fluctuate easily during the initial 30 minutes, requiring a temperature stabilization run.
7. The difficulty of dressing is completely different from that of a regular grinding wheel
Ceramic CBN cannot be dressed with ordinary grinding wheel dressers; improper use will cause surface dulling and render the wheel unusable.
8. Spindle load current rises
CBN grinding wheels have greater self-weight and different cutting resistance characteristics, resulting in higher machine tool current compared to conventional grinding wheels.
