摘要： A porous, hydrostatic gas-bearing with whirl stability and static stiffness, having a porous ceramic bushing supporting a rotating journal with a bearing clearance, through which bushing a pressurized gas is fed into the clearance to lubricate the rotating journal, which is characterised in that a porous ceramic material having a gas permeability satisfying at least one of the following relationships (1), (2) and (3) is used as the bushing: K ≦ 7 x 10⁻¹⁵ q ≦ 2.07x10⁻¹³P₁² - 6.84x10⁻⁹P₁ - 6.9x10⁻³
and Y
wherein K (m²) is a gas permeating rate, q (m³/s·m²) is a mass rate of gas flow per unit area, and Y is a gas permeability coefficient. This gas-bearing can be used with whirl stability at a maximum rotating speed of the journal of 30,000 r.p.m. or more within a range defined by the above parameter, K, q or Y.

摘要： An apparatus for removing ground dust from the surface of a grinding wheel (1,38,45,55) including a blasting apparatus (9,31,47,57) for application in a dry grinding process of ceramic work piece (7,39,52,60). The blasting apparatus (9,31,47,57) blasts abrasive grains against the surface of the grinding wheel (1,38,45,55). A circulating passage (13,33a,33b), both ends of which are connected with the blasting apparatus (9,31,47,57), receives the abrasive grains in the vicinity of the apparatus and returns them to the blasting apparatus (9,31,47,57). By such process, the grinding of the work piece (7,39,52,60) and ground dust removal from the surface of the grinding wheel (1,38,45,55) can be accomplished simultaneously, efficiently and speedily. Further, the blasted abrasive grains are recovered and recycled, enabling a reduction in grinding process costs.
