A hammer drill includes a tool holder, two balls in reception holes in the tool holder, a guide washer urging the balls forward in the reception holes with a coil spring, a pressure ring adjacent to a front of the guide washer, and an operation sleeve allowing the pressure ring to move backward and forward between locked and unlocked positions of the two balls. The guide washer includes, on its front surface, a projection toward the pressure ring to cause, with the pressure ring at the locked position, the guide washer to be inclined with respect to an axis of the tool holder for a first ball to move more backward than a second ball.

A first side of the adjusting block is attached with a cutter handle, and a second side is connected with the adjusting block for rake angle and relief angle by the adjusting block for tool cutting edge angle and minor cutting edge angle. The milling machine fly-cutter realizes adjustment of the geometric angles of cutting tool, and is able to adapt to cutter handles of a variety of different specifications.

Abstract: A universal adapter to facilitate the easy and efficient of exchange of needle scaler and chisel accessories associated with an air tool receiver/coupler, the adapter including a sleeve with a spring and a spacer, an adapter carrying an O-ring, and an anvil member in contact with the base of a plurality of needles is disclosed herein.

Abstract: An alignment device has a support base attached to a conveying device, and a mounting plate to which a gripping member is attached, and the mounting plate is transferably abutted on a fastening holder that is fixed to the support base. A movable ring fixed to the mounting plate has a sliding part that is transferably engaged with the fastening holder. A first holding mechanism arranged between the fastening holder and the mounting plate locks the mounting plate to the fastening holder. A second holding mechanism provided between the fastening holder and the movable ring cancels a first-direction force of the mounting plate.

Abstract: A semiconductor fabricating apparatus may include a collet structure configured to pick-up a semiconductor chip. The collet structure may include a holder, a plate, an absorption member and an edge contact. The holder may be configured to downwardly receive vacuum. The holder may include a magnet arranged in the holder. The plate may include an upper surface magnetically and mechanically combined with the holder. The plate may include a sidewall wholly exposed by the holder. The plate may receive the vacuum from the holder. The absorption member may make contact with the plate to pick-up the semiconductor chip using the vacuum received from the plate. The edge contact may include a protrusion having a first length protruded from an edge portion of a bottom surface of the holder to make contact with the plate.

Abstract: A suction adapter, in particular a suction drill suction adapter, for connecting an insertion tool, in particular a suction drill, to a suction apparatus includes at least one insertion tool receiving region, in which the insertion tool is arranged, at least one connection interface with respect to an insertion tool suction channel of the insertion tool, and at least one, in particular dimensionally stable, discharge guiding unit configured to delimit a suction channel. The at least one discharge guiding unit has at least one discharge guiding element configured to delimit a suction channel outlet of the suction channel and which has a longitudinal axis. The longitudinal axis of the at least one discharge guiding element is orientated parallel with a main extent axis of the at least one insertion tool receiving region in a region of the suction channel outlet in at least one operating state.

Abstract: An air chuck includes: a finger support part including a pair of fingers and a pair of lock shafts; a chuck main body part including an operation mechanism operable to open and close the fingers; and linking mechanisms that detachably link the finger support part to the chuck main body part. Each of the linking mechanisms causes the corresponding lock shaft to shift to a non-lock position so as to render the pair of fingers capable of being opened and closed when the finger support part is linked to the chuck main body part. Each of the linking mechanisms causes the corresponding lock shaft to shift to a lock position and locks the pair of fingers so as to render the pair of fingers incapable of being opened and closed when the finger support part is detached from the chuck main body part.

Abstract: A wafer processing apparatus includes a vacuum chuck on which a wafer is seated, a ring cover disposed along a circumferential portion of the vacuum chuck to press the wafer to seal the circumferential portion of the vacuum chuck, and a sealing ring pressed against an adhesive sheet on the wafer and pressed by the ring cover.

Abstract: An air chuck includes: a finger support part including a pair of fingers; a chuck main body part including an operation mechanism operable to open and close the pair of fingers; and linking mechanisms that detachably link the finger support part to the chuck main body part. The linking mechanisms each include: a linking shaft that extends from the finger support part; a shaft insertion hole formed in a body of the chuck main body part; a catch body that becomes elastically caught on a catch surface of the linking shaft when the linking shaft is inserted into the shaft insertion hole; and a delinking member that is manually operated so as to release the catch body caught on the catch surface when the finger support part is detached from the chuck main body part.

Abstract: Some examples provide a vacuum wafer chuck assembly for supporting a wafer. An example chuck assembly comprises a chuck hub and a centering hub disposed within the chuck hub. Chuck arms are mounted to the chuck hub, with each chuck arm extending radially between a proximal end adjacent the chuck hub, and a distal end remote therefrom. At least one vacuum pad is provided for supporting the wafer during a wafer centering or wafer processing operation. A vacuum sensor detects a presence or absence of a vacuum pressure at the vacuum pad during the wafer centering or processing operation, a detection indicative of a presence or absence of the wafer in the chuck assembly, or a presence of a defective wafer.
