The utility model integrates the rough cutting edge and the fine cutting edge on one cutting edge, and a chip groove is formed between the adjacent cutting edges, so that the utility model has enough chip containing space during cutting; notches are uniformly arranged on the cutting edge, so that scraps are uniformly discharged; the width that sets up middle chip groove is less than the width of both ends chip groove, and reasonable in design satisfies the actual production demand.
Description
Technical Field
The utility model relates to a milling cutter, especially an unequal rough and fine integrated milling cutter.
Background
When machining a workpiece, the workpiece is generally rough machined and then finish machined. Now in order to save time, reduce manufacturing procedure, improve work efficiency, set up the collocation of rough cutting edge and finish cutting edge on the tool bit of milling cutter, can accomplish rough finishing like this simultaneously. The coarse cutting edge and the fine cutting edge on the existing tool bit are separately arranged, so that the chip containing space is insufficient, and the cutting effect is influenced. In addition, according to actual production, the chip removal in the middle is more, and the chip removal at two ends is less, so the size of the chip groove can be reasonably designed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: overcomes the defects in the prior art and provides an unequal rough and fine integrated milling cutter.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a rough smart milling cutter of partition not, includes handle of a knife and the tool bit of setting in handle of a knife one end, be equipped with a plurality of spiral cutting edges on the tool bit, the cutting edge includes the rough cutting sword of anterior segment and the finish cutting sword of back end, the height that highly is less than the finish cutting sword of rough cutting sword evenly is provided with the notch on the cutting edge, the notch is the structure of falling trapezium, forms the chip groove between the adjacent cutting edge, and the width of middle chip groove is less than the width of both ends chip groove.
In order to ensure that the edge is not broken during feeding, the feeding position of the front end of the thick cutting edge is further limited to be arc-shaped.
In order to ensure the machining precision and enough chip containing space, the cutter head is further limited to be provided with four spiral cutting edges arranged on the outer peripheral surface of the cutter head.
In order to guarantee the utility model discloses milling cutter's structure bulk strength further prescribes a limit to, the length of tool bit equals the length of handle of a knife.
In order to guarantee the service life of the cutting edge, the edge part of the cutting edge is further limited to be provided with a coating with the thickness of 0.002-0.003 mm.
More particularly, the coating is a titanium nitride coating, a titanium carbonitride coating, a titanium oxychloride coating, a chromium aluminum nitride coating, a chromium nitride coating, or a silicon coating.
The utility model has the advantages that: the utility model integrates the rough cutting edge and the fine cutting edge on one cutting edge, and a chip groove is formed between the adjacent cutting edges, so that the utility model has enough chip containing space during cutting; notches are uniformly arranged on the cutting edge, so that scraps are uniformly discharged; the width that sets up middle chip groove is less than the width of both ends chip groove, and reasonable in design satisfies the actual production demand.
Drawings
The present invention will be further described with reference to the accompanying drawings and embodiments.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the structure of fig. 1 in the direction a.
In the figure: 1. the cutting tool comprises a tool shank, 2 parts of a tool bit, 3 parts of a coarse cutting edge, 4 parts of a fine cutting edge, 5 parts of a notch and 6 parts of a chip groove.
Detailed Description
The invention will now be further described with reference to the accompanying drawings. The drawings are simplified schematic diagrams only illustrating the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1 and 2, an unequal rough and fine integrated milling cutter comprises a cutter handle 1 and a cutter head 2 arranged at one end of the cutter handle 1, wherein the length of the cutter head 2 is equal to that of the cutter handle 1, four spiral cutting edges arranged on the peripheral surface of the cutter head 2 are provided, each cutting edge comprises a rough cutting edge 3 at the front section and a fine cutting edge 4 at the rear section, the height of the rough cutting edge 3 is smaller than that of the fine cutting edge 4, notches 5 are uniformly arranged on the cutting edges, each notch 5 is of an inverted trapezoidal structure, a chip groove 6 is formed between every two adjacent cutting edges, and the width of each middle chip groove 6 is smaller than that of the chip grooves 6 at the two ends.
In the present embodiment, the rough cutting edge 3 has an arc shape at the front end cutting feed. The edge part of the cutting edge is provided with a chromium nitride coating with the thickness of 0.0025 mm.
The cutter head 2 is provided with four spiral cutting edges arranged on the outer peripheral surface of the cutter head, so that the service life of the cutting edges is ensured; the rough cutting edge 3 and the fine cutting edge 4 are integrated on one cutting edge, and a chip removal groove 6 is formed between the adjacent cutting edges, so that a sufficient chip containing space is formed during cutting; notches 5 are uniformly arranged on the cutting edge, so that scraps are uniformly discharged; the width of the middle chip groove 6 is smaller than the width of the chip grooves 6 at the two ends, the design is reasonable, and the actual production requirement is met.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable people skilled in the art to understand the contents of the present invention and implement the present invention, and the protection scope of the present invention can not be limited thereby, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
