Description
Technical field
The present invention relates to a kind of machine tools, and in particular to a kind of Unequal distance end mill(ing) cutter.
Background technology
Milling cutter is common tool in mechanical processing, is widely used in the parts such as processing automobile, communication and aerospace, right
When the end face processing of parts, the cutter head of the existing end mill(ing) cutter in market only has finish-milling blade or rough mills blade, therefore can only realize open
Thick or finishing individual event function generally first removes the extra material of workpiece with opening thick knife, and made allowance finishes, then with finishing knife
Tool removes allowance for finish, and processing efficiency is relatively low.
Invention content
In order to solve the above problem, a kind of Unequal distance end mill(ing) cutter of present invention offer can be carried significantly when being processed using the end mill(ing) cutter
For processing efficiency.
The technical solution adopted by the present invention is：A kind of Unequal distance end mill(ing) cutter, including knife bar and link into an integrated entity with knife bar
Cutter head, it is characterised in that：The cutter head is equipped with several finish-milling blades and rough mills blade, along knife bar axial direction, the finish-milling
The height of blade, which is higher than, rough mills blade；Along knife bar circumferencial direction, the finish-milling blade outer diameter, which is less than, rough mills blade outer diameter.
Preferably, several finish-milling blades are symmetricly set on cutter head in pairs, described several to rough mill blade also pairs of
It is symmetricly set on cutter head.
Further, the finish-milling blade is equal with blade quantity is rough milled, and is arranged at intervals on cutter head.
Further, the finish-milling blade on the cutter head and to rough mill the quantity of blade be two.
Further, the finish-milling blade with rough mill the spiral of blade away from equal with helical angle.
Preferably, along knife bar axial direction, the finish-milling blade and the difference in height for rough milling blade are 0.15~0.25mm.
Preferably, along knife bar circumferencial direction, the finish-milling blade outer diameter and rough mill blade outer diameter difference be 0.4~
0.6mm。
Further, the finish-milling blade is within 1.5mm with the total scrap rate of blade is rough milled.
The advantageous effect that the present invention obtains is：It is equipped with several finish-milling blades on cutter head and rough mills blade, along knife bar axial direction
Direction, the height of finish-milling blade, which is higher than, rough mills blade；Along knife bar circumferencial direction, finish-milling blade outer diameter, which is less than, to be rough milled outside blade
Diameter, by the end mill(ing) cutter, single process can once realize out that thick and two functions of finishing, collection run thick and two knives of finishing jointly
The function of tool；Several finish-milling blades and several blades of rough milling are symmetricly set on cutter head in pairs so that end mill(ing) cutter is in processing
It is more steady.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
State diagram when Fig. 2 is riveting；
Fig. 3 is machining sketch chart；
Fig. 4 is the partial enlarged view of working position.
Specific implementation mode
The present invention is further described in the following with reference to the drawings and specific embodiments.
As shown in Figs. 1-2, a kind of Unequal distance end mill(ing) cutter of the invention, including knife bar 1 and cutter head 2, knife bar 1 and cutter head 2 connect
It is connected into integral structure, cutter head 2 is equipped with several finish-milling blades 21 and rough mills blade 22, along 1 axial direction of knife bar, finish-milling blade 21
Height higher than rough milling blade 22；Along 1 circumferencial direction of knife bar, 21 outer diameter of finish-milling blade, which is less than, rough mills 22 outer diameter of blade.The end
Milling cutter is used for processing precise die casting, carries out micro cutting to accurate die casting, when processing, the low increment of major diameter rough mills blade 22
Workpiece is first encountered for rough milling, and workpiece is encountered after the finish-milling blade 21 of the high increment of path and is processed for finish-milling.Realize an end
Milling cutter collection runs thick and two cutters of finishing function jointly, substantially increases processing efficiency.
In one embodiment, several finish-milling blades 21 are symmetricly set in pairs on cutter head 2, several to rough mill blade 22 also in pairs
It is symmetricly set on cutter head 1.In the present embodiment, finish-milling blade 21 is equal with 22 quantity of blade is rough milled, and is arranged at intervals on cutter head 2
On so that cutter structure is more reasonable, and when processing is more steady.
In one embodiment, the finish-milling blade 21 on cutter head 2 and to rough mill the quantity of blade 22 be two, in the present embodiment
Finish-milling blade 21 with rough mill the spiral of blade 22 away from equal with helical angle, cutter making is simpler.
In one embodiment, as shown in Figure 1, along 1 axial direction of knife bar, finish-milling blade 21 and the difference in height for rough milling blade 22
H is 0.15~0.25mm.In the present embodiment, as shown in Fig. 2, along 1 circumferencial direction of knife bar, finish-milling blade outside diameter d and roughing milling cutter
Sword outer diameter D difference is 0.4~0.6mm.Finish-milling blade 21 is within 1.5mm with 22 total scrap rate of blade is rough milled.
As shown in Figure 3-4, operation principle of the invention is：When processing, the cutter head 2 of end mill(ing) cutter from the side feed of workpiece 3,
It rough mills the roughing layer that blade 22 is first encountered on workpiece 3 and encounters the finishing layer of workpiece 3 after finish-milling blade 21 for rough milling, use
It is processed in finish-milling, after processing is completed, rough mills blade 22 and cut away roughing layer on workpiece 3, finish-milling blade 21 cuts away workpiece 3
On finishing layer, the total scrap rate cut away be 1.5mm within (adjusted according to material difference).
