The profile grinding machine includes: a base; a work unit disposed on one side on the base and including a work table for gripping a work; and a stone unit disposed on the other side on the base and including a stone rotating mechanism for holding and rotating a grinding stone on its axis. The work unit includes first to third moving device for supporting and moving the work table in an X-direction and a Y-direction perpendicular to each other in a horizontal plane, and in a Z-direction normal to the horizontal plane, respectively. The stone unit includes turning mechanism for turning the grinding stone about a vertical axis substantially coinciding with the leading end portion of the grinding stone.

Particulate object conveying apparatus

A particulate object conveying device is provided, and the conveying device includes a stagnating portion. A rotor has an outer circumference having a plurality of grooves formed equidistantly about the outer circumference, the grooves being of a size and shape to hold a single one of the particles of predetermined size. The rotor rotates within the stagnating portion. A discharge path is provided for discharging the particles from the rotor.

Particulate objects conveying apparatus for conveying particles of a predetermined size

The present invention relates to a device for conveying spherical articles at high speed between sequential processes having different protective atmospheres, where the leakage of the atmospheres, which must be converted between the sequential processes, is prevented. The device includes a structure incorporating a rotary relay having a plurality of spherical-article accommodating chambers formed at predetermined intervals, a support container closely mounted on the rotary relay, and having a spherical-article receiving passage and a discharge passage. An atmosphere discharge pipe communicates with the spherical-article accommodating chambers of the rotary relay, and an atmosphere supply pipe is disposed adjacent to the spherical-article discharge portion of the rotary relay and communicates with the accommodating chambers.
