Abstract
The utility model relates to a four-edge forming cutter used in machining. The forming cutter comprises a cutter handle used for clamping and a cutting head arranged at one end of the cutter handle. Four cutting edges which are arranged in a spiral mode are arranged on the cutting head, a scrap removing groove is arranged between adjacent spiral cutting edges, the cutting edges comprise a first cutting edge, a second cutting edge and a peripheral face cutting edge, wherein the first cutting edge and the second cutting edge are arranged on the front end face of the cutting head, the peripheral face cutting edge is arranged on the peripheral face of the cutting head, one end of the first cutting edge extends to the center of the cutting head, the other end of the first cutting edge is connected with one end of the second cutting edge, and the first cutting edge and the second cutting edge are arc cutting edges. When an aluminum alloy workpiece is machined, the first cutting edge, the second cutting edge and the peripheral face cutting edge can machine the workpiece at one time without replacing other cutters, machining precision of the aluminum alloy workpiece is ensured, and machining efficiency is improved.
Description
Technical field
The utility model relates to a kind of cutter in the machining, the four sword forming cutters that are specifically related to use in a kind of machined.
Background technology
Al alloy parts is added man-hour, needing to adopt a plurality of different cutters and frequently replacing, can finish the processing to workpiece, such manufacturing procedure is complicated, and trueness error in various degree all can appear in each tool changing, thereby has reduced machining accuracy, has also reduced working (machining) efficiency simultaneously.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of four sword forming cutters, and the processing that it can once be finished workpiece need not to change cutter, guarantees the machining accuracy of workpiece, improves working (machining) efficiency.
The realization the technical solution of the utility model is as follows:
Four sword forming cutters, comprise the handle of a knife for clamping, be arranged on the cutting head of handle of a knife one end, be provided with the cutting edge of four screw arrangement on the described cutting head, between adjacent spiral cutting sword, be provided with chip area, described cutting edge comprises the first cutting edge that is arranged on the cutting-head forward end face, the second cutting edge, and be arranged at side face cutting edge on the cutting head side face, one end of the first cutting edge extends to the center of cutting head, the other end is connected with an end of the second cutting edge, the other end of the second cutting edge is connected with an end of side face cutting edge, and the other end of side face cutting edge is cutting edge end; Described the first cutting edge, the second cutting edge are arc edge.
The circular arc number of degrees of described the first cutting edge are less than the circular arc number of degrees of the second cutting edge.
Be fixedly installed welding ends on the described cutting head, this welding ends and handle of a knife weld together.
Adopted such scheme, Al alloy parts is being added man-hour, and the first cutting edge, the second cutting edge and side face cutting edge once just can be processed workpiece, need not to change other cutters, guarantee the machining accuracy of Al alloy parts, improved working (machining) efficiency.
