Abstract
The utility model belongs to the field of cutting tools, in particular to a double-edge straight-groove ball cutter which comprises a cutter handle. One end portion of the cutter handle is provided with a cutter head in an integrated mode. Two cutting edges are arranged on the cutter head, and a cross section of one end portion of the cutter head is designed to be in a ball shape. Two straight grooves are respectively arranged under the cutting edges of the cutter head. The double-edge straight-groove ball cutter has the advantages of being capable of processing a ball-shaped groove in a one-step forming mode, high in efficiency and fast in speed.
Description
Technical field
The utility model belongs to the cutting tool field, specifically a kind of two sword straight trough ball cuttves.
Background technology
The structure of various cutters all is comprised of clamping part and working portion.Clamping part and the working portion of overall structure cutter all are made on the cutter hub; The working portion of inserted structure cutter (cutter tooth or blade) then is installed on the cutter hub.The clamping of cutter partly has with holes and band handle two classes.Rely on inner hole sleeve to be contained on the main shaft or axle of lathe with spot facing cutter, transmit torsional moment by axial bond or straight end-face key, such as cylindrical milling cutter, facing-type cutter etc.With the cutter of handle three kinds of rectangular shank, cylindrical handle and circular cone handles are arranged usually.Lathe tool, planing tool etc. are generally rectangular shank; The circular cone handle leans on the tapering bearing axial pushing force, and by the frictional force transmitting torque; Cylindrical handle generally is applicable to the cutters such as less fluted drill, slotting cutter, and the frictional force that produces when clamping during cutting is transmitted torsional moment.Much make with low-alloy steel with the shank of the cutter of handle, working portion then forms two parts butt welding with high-speed steel.The working portion of cutter is exactly the part that produces and process smear metal, comprises blade, makes smear metal structure, chip removal or appearance disconnected broken or that wind up store up the space of smear metal, the structural elements such as passage of cutting fluid.The working portion of the cutter that has is exactly cutting tip, such as lathe tool, planing tool, boring cutter and milling cutter etc.; The working portion of the cutter that has then comprises cutting tip and calibrated section, such as drill bit, reamer, reamer, inner surface broaching tool and screw tap etc.The effect of cutting tip is to excise smear metal with blade, and the effect of calibrated section is finished surface and the guiding cutter that smoothing has been cut.
Summary of the invention
The purpose of this utility model provides two sword straight trough ball cuttves of a kind of processing metal sheet material or handicraft.
The utility model provides following technical scheme:
Two sword straight trough ball cuttves, it comprises handle of a knife, and the handle of a knife end has been wholely set cutter head, is provided with two cutting edges on this cutter head, and the cutter head end cross-sectional is set to spherical, respectively is provided with straight trough under the cutting edge on the cutter head.
The radius of a ball R of described cutter head is 3.975mm.
The utility model has the advantages that by two sword straight trough ball cuttves and can one-shot forming process spherical groove, efficient is high, and speed is fast.
