場合には採用できない。[Prior art] In conventional grinding using a double-headed surface grinder using a carrier disc, a carrier disc with equidistributed workpiece holding pockets is continuously rotated to drive two facing grinding wheels. Grinds the workpiece held in the pocket while facing the machine. In this case, the pocket on the carrier disk that holds the workpiece is either a notched pocket on the outer periphery of the carrier disk that matches the shape of the workpiece, or a pocket on a pitch circle near the outer periphery of the carrier disk. A pocket suitable for the shape of the workpiece is provided. The workpieces are fed into these pockets either by a chute using gravity or by being driven in synchronization with the rotation of the pockets of the carrier disk. Workpieces that are fed by a chute generally have a rolling shape, and non-circular workpieces require a special feeding means to synchronize with the pocket, making the equipment complex and expensive and prone to trouble. many. To solve this problem, if the carrier disk is stopped during feeding of the workpiece, the grinding accuracy will be adversely affected, and this method cannot be adopted especially when high-precision grinding is required.

Thereafter, when the workpiece 7 is supplied and the carrier disk 4 is driven to rotate again, the positions a and b are
The workpieces 7, 7 at the positions engage the grinding surfaces 2, 2 and are ground. In other words, the workpiece 7 does not stop in the state where it is engaged with the machining surfaces 2, 2 of both wheels, and the feed rate remains constant (carrier disk 4
This ensures stable grinding conditions.

よい。 Since the workpiece 7 at position c has already been ground, it continues as it is and is removed by the ejection means 9.
It is discharged from the pocket 5 of the carrier disc 4. This ejecting means 9 may be a natural fall, a chute may be used to slide the ejecting means 9, or a ejecting device using a drive as shown in the illustrated example may be used. In any case, it may be determined depending on conditions such as the shape of the workpiece 7 and the content of grinding.

本考案を満足することができる。 For example, in the illustrated example, the grinding surface 2 is an annular surface, the pockets 5 are equally spaced into eight, and the indexing of the intermittent rotation drive is also divided into eight. On the other hand, when the grinding surface 2 is a circular surface formed over the entire surface of the grinding wheel 1, in the case of the pocket 5 located at the a position and the c position, this pocket 5 is If the intermittent indexing is divided into four parts,
The present invention can be satisfied.
