Abstract:
A cutter fastening apparatus has a body, a collet, a cutter, and a cap. The body has an outer thread. The collet is mounted in the body and has an abutting groove formed in an outer surface of the collet and a through hole formed through a front surface of the collet. The cutter is mounted through and fixed to the through hole of the collet. The cap is screwed with the outer thread of the body and has a driving ring portion protruding from an inner surface of the cap and a balance groove formed in the inner surface of the cap and being adjacent to the driving ring portion. The cap has a clamping portion protruding from the inner surface of the cap and a holding portion protruding from the inner surface of the cap.
Abstract:
A cutter holder has a body and a buffering assembly. The body has a specific weight. The buffering assembly is mounted in the body and has a buffering unit and an elastic unit set. The buffering unit has a specific weight that is larger than the specific weight of the body. The buffering unit and the elastic unit set are utilized for absorbing vibration. The elastic unit set has multiple Belleville washers and can be changed in scales or amounts according to practical machining conditions.
Abstract:
The fan screw nut for removing scraps includes a screwing hub, multiple fan blades and a frame. The screwing hub has an outer periphery. The fan blades are spiral in shaped and are formed around the outer periphery of the screwing hub. A flux space is formed between each fan blade. The frame is formed integratedly on an outer periphery of a front side of the fan blades. Multiple through holes are formed between the inner side of the frame and the flux spaces for air flowing. The fan screw can be introduced air into flux space via through holes to blow up scraps that generated from cutting a work piece.
