Abstract
The invention discloses an unequal-screw unequal-division end milling cutter which comprises a cutter handle and a milling part arranged at one end of the cutter handle. The milling part is provided with a plurality of periphery cutting edges, screw chip grooves each located between the two corresponding adjacent periphery cutting edges and end tooth cutting edges. The screw angles of every two adjacent screw chip grooves are unequal, the included angles of every two adjacent end tooth cutting edges are unequal, and the included angles of the two end tooth cutting edges on each diagonal line are equal. In this manner, according to the unequal-screw unequal-division end milling cutter, during cutting machining, resonance oscillation can be avoided, the surface smoothness of a machined component can be increased, the machining quality of the product surface can be improved, the use stability of the cutter can be enhanced, and the service life of the cutter can be prolonged.
Description
Technical field
The present invention relates to the technical field in hard alloy cutter, particularly relate to one and do not wait spiral not decile vertical milling
Cutter.
Background technology
As CNC process technology is increasingly mature, working (machining) efficiency is increasingly taken seriously, and it directly determines the height of processing cost
Low, the length of delivery cycle.For this present situation, exigence improves the working (machining) efficiency of conventional tool.Ensure machining
During the stability of working angles, the generation of vibration in suppression process plays very big work to improving machining efficiency
With.
The existing processing to metal material, traditional slotting cutter, helical angle is fixed value, the space width phase of cutter Zhou Ren
With, in process, tap workpiece with fixing frequency, thus cause workpiece to produce chatter in process because of resonance,
Under certain condition, it is identically formed resonance with intrinsic frequency, by making cutter produce bigger vibration, cause cutter to damage, processing
Surface quality reduces, and has had a strong impact on the quality of converted products.
Content of the invention
The technical problem that present invention mainly solves is to provide one and does not wait spiral not decile slotting cutter, adjacent two helical forms
The helical angle of chip area is unequal, and the angle of adjacent two end tooth blades is unequal, can be in machining, it is to avoid resonance
Occur, by increasing capacitance it is possible to increase processed parts surface fineness, improve the crudy of product surface, strengthen cutter stability in use,
And tool life.
For solving above-mentioned technical problem, one aspect of the present invention is：Provide one and do not wait spiral
Discrete milling cutter, including handle of a knife and the milling portion being arranged on handle of a knife one end, described milling portion is provided with multiple peripheries cutting edge, position
Helical form chip area between adjacent two periphery cutting edges and end tooth blade, described adjacent two helical form chip areas
Helical angle unequal, the angle of described adjacent two end tooth blades is unequal, the angle of cornerwise two end tooth blades
Equal.
In a preferred embodiment of the present invention, the quantity of described end tooth blade is four.
In a preferred embodiment of the present invention, the helical angle of described helical form chip area is θ1=42 ° and θ2=44°
In a preferred embodiment of the present invention, the angle of described end tooth blade is that the angle of α and β, α and β compares skew with 90 °
Difference 2-3 °.
The invention has the beneficial effects as follows：The present invention does not waits spiral not decile slotting cutter, adjacent two helical form chip areas
Helical angle unequal, the angle of adjacent two end tooth blades is unequal, can be in machining, it is to avoid the generation of resonance,
Processed parts surface fineness can be increased, improve the crudy of product surface, strengthen cutter stability in use, Yi Jiyan
Long cutter life.
