Description
Technical field
The present invention relates to a kind of milling cutter, particularly a kind of arc cutter block.
Background technology
The side of phone housing is generally all designed to smooth arc shape in order to attractive in appearance, thus is molded in phone housing
Need its side being processed into the arcwall face of best bright finish afterwards, common mode is processed using milling cutter, typically first with one
Milling cutter is crossed once, milling cutter reprocessed once using one again after allowing, aforesaid way needs tool changing, not only process time
Length, efficiency are low, and high processing costs.Thus the applicant devises a arc cutter block to solve the above problems.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of arc cutter block.
The technical solution adopted for the present invention to solve the technical problems is：
The cutter head includes some combination cutting portions, and the combination cutting portion includes rough milling cutting portion and finish-milling cutting portion, described
One end that cutting portion is located remotely from knife bar is rough milled, the cutter head is provided with the chip area for extending to knife bar, and the chip area is located at
Between two combination cutting portions, the cutting portion of rough milling includes rough cut sword and rough mills rear knife face, the portion of a side wall of the chip area
Point edge, which is formed, rough mills rake face, and the rough cut sword is crossed to form to rough mill rear knife face and rough milling rake face, and the finish-milling is cut
Cutting portion includes knife face after finish cutting sword and finish-milling, and another part edge of a side wall of the chip area forms finish-milling rake face,
The finish cutting sword is crossed to form for knife face after finish-milling and finish-milling rake face.
The shape of the rough cut sword and finish cutting sword is formed by the continuous camber line of multistage.
It is described to rough mill rear knife face and rough mill rear knife face including first and second rough mill rear knife face.
Knife face includes knife face after knife face after the first finish-milling and the second finish-milling after the finish-milling.
The chip area is helicla flute.
The cutting portion of rough milling is provided with anchor point.
The beneficial effects of the invention are as follows：The cutter head of the present invention includes some combination cutting portions, and the combination cutting portion includes
Rough mill cutting portion and finish-milling cutting portion, described one end rough milled cutting portion and be located remotely from knife bar, thus in processing mobile phone shell
When first can ensure processing capacity with rough milling cutting portion its side is carried out roughing, then cutter decline certain distance is led to again
Cross finish-milling cutting portion and finishing guarantee precision and finish are carried out to its side, said process does not have to tool changing, thus not only saves
Tool change time, improve efficiency and precision is more preferable, processing cost is lower.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the three-dimensional structure diagram of the present invention；
Fig. 2 is zoomed-in view at Fig. 1 A.
Embodiment
Reference picture 1, Fig. 2, the invention discloses a kind of arc cutter block, including circular knife bar 1 and cutter head 2, the knife
First 2 include three combination cutting portions, and the combination cutting portion includes rough milling cutting portion and finish-milling cutting portion, described to rough mill cutting portion
One end of knife bar 1 is located remotely from, the cutter head 2 is provided with the chip area 3 for extending to knife bar 1, and the chip area 3 is positioned at two combinations
Between cutting portion, the cutting portion of rough milling includes rough cut sword 4 and rough mills rear knife face, the part side of a side wall of the chip area 3
Rake face is rough milled along forming, the rough cut sword 4 is crossed to form to rough mill rear knife face and rough milling rake face, the finish-milling cutting portion
Including knife face after finish cutting sword 5 and finish-milling, another part edge of a side wall of the chip area 3 forms finish-milling rake face, institute
Finish cutting sword 5 is stated to be crossed to form for knife face after finish-milling and finish-milling rake face.
The shape of the rough cut sword 4 and finish cutting sword 5 is formed by the continuous camber line of multistage, because phone housing side
Arc may be that the different cambered surface of multiple radians is formed, thus the shape of rough cut sword 4 and finish cutting sword 5 need to also be connected by multistage
The camber line that the continuous contour line with cambered surface matches is formed, so as to be phone housing processing.
Rough mill rear knife face as illustrated, described and rough mill rear knife face 6 including first and second rough mill rear knife face 7；The finish-milling
Knife face includes knife face 9 after the finish-milling of knife face 8 and second after the first finish-milling afterwards.In said structure, continuous multiple rear knife faces are designed with
Profit gently drops to low-angle relief angle from the relief angle of wide-angle, both can guarantee that cutter head 2 has enough intensity, can reduce cutting edge again
Friction between machined surface, prevent from generating heat, so as to effectively in raising cutting precision.
The chip area 3 is helicla flute, and spiral helicine chip area 3 not only holds that bits amount is big, and in the process of cutter rotation
In, iron filings are larger by the extruding force of the wall of chip area 3, so as to quickly guide iron filings to discharge.
As further design, the cutting portion of rough milling is provided with anchor point 10, and anchor point 10 is to rough mill cutting portion
The summit in outside is formed, and cutter head 2 declines rear-face contact of the summit first with phone housing during processing, and the back side of phone housing is as base
Quasi- face, and cutting portion is rough milled in this structure three, thus 3 points of compositions, one plane, can be used for cutter positioning, pass through
Cutter positioning can accurately control the depth that cutter declines.
Described rough mill is provided with transition blade between cutting portion and finish-milling cutting portion, the transitional cut sword 11 of the transition blade is
One section of straight line, can be used as backup cutting sword by the setting of transition blade can also avoid rough cut sword 4 and 5 direct phase of finish cutting sword
Hand over and form cusp, and cause easily to crumble in working angles.
A kind of arc cutter block provided above the embodiment of the present invention, is described in detail, used herein
Specific case is set forth to the principle and embodiment of the present invention, and the explanation of above example is only intended to help and understands
The method and its core concept of the present invention；Meanwhile for those of ordinary skill in the art, according to the thought of the present invention, having
There will be changes in body embodiment and application, in summary, this specification content should not be construed as to the present invention
Limitation.
