Claims

[Claims for Utility Model Registration] (1) A main body frame in which two rotary grindstones are coaxially arranged facing each other, and a rotating arm that holds a workpiece are swung to carry the workpiece between the two grindstones of the main body frame. a carrier device having means for rotating a workpiece pocket gear that holds the workpiece on a rotating arm to impart rotational motion to the workpiece; and means for reciprocating a block on which the rotating arm is arranged to impart oscillation motion to the workpiece; It consists of a carrier frame to which a carrier device is assembled, and the carrier frame is attached to the main body frame so that it can be opened and closed in a direction perpendicular to the grinding wheel axis using a point on a part of the main frame or a point outside the main frame as a fulcrum. Vertical double-headed surface grinder with special features. (2) The rotating contact surfaces of both the work pocket gear that holds the work and the swing arm that comes into contact with the work pocket gear are provided with at least a wear-resistant material whose surface is made of oxidized, nitrided, or carbonized fine ceramic. A vertical double-head surface grinder as set forth in claim 1 of the above-mentioned utility model registration claim.
