Abstract
The utility model relates to a kind of screw-on cutter of improvement, and it includes: handle of a knife, cutter hub, and cutter hub is containing some spiral cutting swords, chip area; Described cutter head body is also provided with two location blades, and described spiral cutting sword is provided with some U-shaped chip-breakers at a distance of a determining deviation along the hand of spiral, and the spiral angle of chip-breaker is 55 ° ~ 85 °.Advantage of the present utility model: be provided with two location blades at this screw-on cutter head, be convenient to the accurate location of screw-on cutter, then be provided with the U-shaped chip-breaker on multiple chip area and spiral cutting sword along direction, milling body portion.Chip area and chip-breaker have different spiral angles, are conducive to the bits reducing milling process generation, reduce milling temperature, reduce broken needle rate, increase the quick discharge of chip space and scrap, avoid the phenomenon producing Integrated Chip and edges of boards burr.
Description
Technical field:
The utility model relates to screw-on cutter field, particularly relates to a kind of screw-on cutter of improvement.
Background technology:
Move towards light gradually at electronic product, thin, short, under little epoch trend, various electronic product volume is also reduced gradually, this trend makes the manufacture of the various parts of electronic product inside, process relative more and more meticulousr, and the printed circuit board (PCB) of printed circuit for electronic component group setting position in various electronic product, must be had, the volume of this printed circuit board (PCB) also must along with the volume-diminished of electronic product, and along with the performance of various electronic product gets more and more, circuit in printed circuit board (PCB) becomes increasingly complex, the layers of copper number of printed circuit board (PCB) gets more and more thereupon, milling cutter is in the process of machining pcb board material, easily there is broken needle, burr and the situation such as chip removal is bad, for preventing the generation of these situations, adopt a kind of screw-on cutter of improvement to reduce the situation of size improvement chip removal and the burr producing bits, improve milling cutter chip power and reduce broken needle.
Utility model content:
The purpose of this utility model be provide for the deficiencies in the prior art a kind ofly can reduce the bits produced in milling process, the resistance reduced in milling process, the screw-on cutter that reduces broken needle risk, improve the improvement in service life.
The purpose of this utility model is realized by following measures: a kind of screw-on cutter of improvement, it includes handle of a knife, cutter hub, cutter hub is containing some spiral cutting swords, chip area, it is characterized in that, described cutter head body is also provided with two location blades, described spiral cutting sword is provided with some U-shaped chip-breakers at a distance of a determining deviation along the hand of spiral, and the spiral angle of chip-breaker is 55 ° ~ 85 °.
Compare with technology with existing equipment, the screw-on cutter of a kind of improvement that the utility model proposes, tool has the following advantages: the utility model is provided with two location blades at this screw-on cutter head, be convenient to the accurate location of screw-on cutter, be provided with the U-shaped chip-breaker on multiple chip area and spiral cutting sword along direction, milling body portion again, the spiral angle of chip-breaker is 55 ° ~ 85 °.Chip area and chip-breaker have different spiral angles, are conducive to the bits reducing milling process generation, reduce milling temperature, reduce broken needle rate, increase the quick discharge of chip space and scrap, avoid the phenomenon producing Integrated Chip and edges of boards burr.
Accompanying drawing illustrates:
Fig. 1 is the embodiment schematic perspective view that the utility model proposes.
Fig. 2 is the side view of Fig. 1 embodiment.
Description of reference numerals: 1-milling cutter, 12-cutter hub, 140-spiral cutting sword, 142-chip area, 141-chip-breaker, 11-handle of a knife, 13-locates blade.
Detailed description of the invention: detailed description of the invention is elaborated below in conjunction with accompanying drawing: Fig. 1 ~ 2 give an embodiment of the present utility model.In figure, a kind of screw-on cutter 1 of improvement, it includes handle of a knife 11, cutter hub 12, cutter hub is containing some spiral cutting swords 140, chip area 142, described cutter head body is also provided with two location blades 13, described spiral cutting sword 140 is provided with some U-shaped chip-breakers 141 at a distance of a determining deviation along the hand of spiral, and the spiral angle of chip-breaker 141 is 55 ° ~ 85 °.In this structure, the spiral angle of some chip areas 142 is 10 ° ~ 40 °, and quantity is 4 ~ 9, and the present embodiment is 6, and described chip-breaker is U-shaped, and its spiral angle is 55 ° ~ 85 °.Because chip area and chip-breaker have different spiral angles, the bits that milling process produces can be reduced, reduce milling temperature, reduce broken needle rate, increase the quick discharge of chip space and scrap, avoid the phenomenon producing Integrated Chip and edges of boards burr.
Describe embodiment of the present utility model by reference to the accompanying drawings above; the structure that embodiment provides does not form restriction of the present utility model, and in this area, those skilled in the art make various distortion within the scope of the appended claims or revise all in protection domain.
