A grinding wheel's durability comes from its bonded construction. 3M Grinding Wheels are built by bonding abrasive grain together with resin to create a hard, durable wheel. This construction makes an abrasive wheel that lasts longer than other metal grinding solutions like flap discs and fibre discs, reducing the amount of time spent ...

2.2.γ-Irradiation. Irradiation by γ-rays of 60 Co of the PE samples was carried out in air on the UNU "Gammatok-100″ device of the IPCP RAS at an absorbed dose rate of 3 Gy/s. For irradiation in vacuum, the polymer sample was first pumped out in a glass ampoule in a vacuum setup to a residual pressure of 0.13 Pa, and then the ampoule was sealed off for irradiation in vacuum.
