Abstract
The utility model relates to an aviation, engineering machinery, automobile parts field are used for metal cutting's cutter, especially a center of groove structure goes out water cutter on CNC machining center. It has two central apopores, its characterized in that: be equipped with the slot respectively in the exit of two central apopores and on being located the terminal surface of tool bit, this slot is fan -shapedly, and the length of the long arc wall of this fan -shaped slot be 3mm, and these the fan -shaped slot both sides directly length of wall are 2mm, and the both sides directly contained angle of wall are 40. The utility model provides a less circular arc center apopore in general standard rod cutter both sides, and improved the flow and the velocity of flow of coolant liquid in the course of working of reality to heat and the cutting bits that produce are cut in faster taking away, and the thermal conductivity that the messenger cut the material reduces, improves the discharge nature of smear metal, thereby obtains higher the line of cut speed, shortens the life -span of processing the beat and prolonging the cutter greatly.
Description
Technical field
The utility model relates to aviation, engineering machinery, auto parts and components field for the cutter of metal cutting on CNC machining center, particularly a kind of center watering cutter of groove structure.
Background technology
In the domestic manufacturing industry auto parts and components field day by day competed at present, enterprise especially focuses on the innovation of technology, reduce manufacturing cost, and the parts relatively high to some machining accuracies, process for machining generally all can select the cutter of central water outlet, but at present at the cutter of central water outlet on the market, water-out manners is all arc diameter water outlet, as Fig. 1, central water outlet uninterrupted can only lean on, both sides arc diameter determines, generally when processing longer deep hole, aluminium bits can not very wellly be discharged from chip area, and in process, just can not obtain higher cutting linear velocity, and easily produce built-up edge in cutter tip, once it is just not sharp to pile up more rear cutter, easy wearing and tearing and fractureing.
Summary of the invention
The purpose of this utility model is the center watering cutter providing a kind of groove structure, solve center of arc's apopore that general standard bar cutter both sides are less, and in the process of reality, improve flow and the flow velocity of cooling fluid, thus take away the heat and cutting swarf that cut and produce faster, the pyroconductivity of cutting material is reduced, improve the discharge of chip, thus obtain higher cutting linear velocity, greatly shorten the life-span of processing beat and prolongation cutter.
For achieving the above object, the technical solution of the utility model is:
A kind of cutter of groove structure central water outlet, it has two central water outlet holes, it is characterized in that: two central water outlet holes exit and the end face being positioned at cutter head is respectively equipped with groove, this groove is fan-shaped, the length of the long arc wall of this fan-shaped groove is 3mm, the length of this straight wall in fan-shaped groove both sides is 2mm, the straight wall in both sides angle be 40 °.
The utility model, compared with existing mechanism, has following advantage.
1, adopt the cutter of the utility model structure, on the actual horizontal Machining centers having 7Mpa central water outlet, tool diameter Φ 18mm also adopts aqueous solution cutting fluid:
(1) General Central water outlet diameter is Φ 2mm cutter: the discharge of cutting fluid is 82ml/sec.
(2) the utility model has the central water outlet spot facing cutter of groove structure: the discharge of cutting fluid is 118ml/sec, flow enhancement 31%.
2, the utility model avoids the problem that center for standard apopore cutter is little, causes chip removal in process freely easily not cause breaking phenomenon, thus extends cutter life.
3, the cutter of the utility model structure is adopted, cutting parameter F800 → F1200(mm/min), shorten the processing beat of product.
Accompanying drawing explanation
Fig. 1 is general center cutter water outlet schematic diagram.
Fig. 2 is the utility model groove structure center watering cutter schematic diagram.
Detailed description of the invention
Refer to Fig. 2, it is the cutter of a kind of groove structure central water outlet of the utility model.As shown in the figure: it has two central water outlet holes, two central water outlet holes exit and the end face being positioned at cutter head is respectively equipped with groove 1, this groove 1 is in fan-shaped, the length of the long arc wall of this fan-shaped groove is 3mm, the length of this straight wall in fan-shaped groove both sides is 2mm, the straight wall in both sides angle be 40 °.
After the utility model improves cutter central water outlet structure, thus the problem that the pre-structure cutter avoided produces, also in actual process, improve cutting parameter, the processing beat and the breaking phenomenon that shorten operation extend cutter life.
Be only preferred embodiment of the present utility model in sum, be not used for limiting practical range of the present utility model.Namely all equivalences done according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
