Embedded debris clogging is embedded in the pores at the wheel working surface

Embedded debris clogging is embedded in the wheel at the work surface pores clogged state. Abrasive type attachment plug is attached by a temporary power after the abrasive cutting surface of the cutting edge a clogging. Adhesion type plug is melted and adhered to the abrasive grinding the cutting edges projecting on weeks or adhesive. Hybrid is more than three types of plug at a small part of the collection or set of layers.
Embedded and dependent-type blocking mechanism
Embedded type  synthetic diamond powder  and debris are mechanically filled voids generated in the wheel clogging. Fill power comes from two aspects, one is external, one internal abrasive grinding  the physical, electrical, thermal and other factors. External factors: grinding a very important feature, the radial grind component is greater than the tangential component Fy Fz, Fy / Fz ≥ 2 ~ 10, more hard workpiece materials, plastic smaller, Fy / Fz ratio greater such debris in the grinding zone of the strong  Diamond blade , is mechanically squeezed into the gap in the wheel surface. From the microscopic analysis of abrasive wear debris along the front slide, abrasive local area in front of several layers of debris piled in the back of abrasive, high-speed rotation of the wheel, the formation of a vortex flow area, vortex area significantly reduced air pressure in the negative pressure, so that part of abrasive wear debris attached to the back, forming abrasive flank dependent blockage, dependent mostly ash and particulate matter.
