Abstract

The utility model belongs to a step milling cutter, including handle of a knife (1) and a plurality of spiral cutting edge (3), be equipped with between each spiral cutting edge (3) to remove and consider helicla flute (2) to be worth doing, the diameter phi 1=8.0 0.022mm of the cutting edge top (4) of its characterized in that spiral cutting edge (3), the diameter phi 3=4.4mm of cutting edge top two (5), cutting edge top two (5) is to top be equipped with between one (4) break (6) of cutting edge, the diameter phi 2=6.4 0.1mm of break (6), the top high H=1mm between (4) of two (5) top cutting edges of cutting edge. The utility model discloses a just can process out the terminal surface of taking the ladder with a milling cutter, production efficiency is high, and is of high quality, milling cutter long service life.

Description

A kind of step milling cutter
Technical field
The utility model belongs to cutter, particularly a kind of step milling cutter.
Background technology
In intermetallic composite coating, usually require to process the stepped end face of band, people adopted the milling cutter of the different-diameter of more than two just can complete in the past.In process, want continuous tool changing tool, often change and once just need centering, alignment, repair type, production efficiency is low, poor product quality, and cutter easily damages.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide and just can process a kind of step milling cutter with ladder end face with a milling cutter.
The technical scheme that the utility model technical solution problem adopts is: a kind of step milling cutter, comprises handle of a knife 1 and multiple spiral cutting edge 3, is provided with debris removal helicla flute 2 between each spiral cutting edge 3, it is characterized in that the diameter of phi of the blade of spiral cutting edge 3 top 1 1=8.0 ± 0.022mm, the diameter of phi of blade point of a knife 25 3=4.4mm; Blade top 25 is provided with break 6 between blade top 1, the diameter of phi of break 6 2=6.4 ± 0.1mm; Height H=1mm between top 25 blades top 1 of blade.
The beneficial effects of the utility model are: this utility model milling cutter just can process the end face of band ladder, and production efficiency is high, and quality is good, milling cutter long service life.
Accompanying drawing explanation
Illustrate with embodiment below in conjunction with accompanying drawing.
fig. 1 isa kind of step milling cutter front view;
fig. 2 is the left side view of Fig. 1.
In figure: 1-handle of a knife; 2-debris removal helicla flute; 3-spiral cutting edge; 4-blade top one; 5-blade top two; 6-break.
Detailed description of the invention
Embodiment, with reference to accompanying drawing, a kind of step milling cutter, comprises handle of a knife 1 and four spiral cutting edges 3, is provided with debris removal helicla flute 2 between each spiral cutting edge 3, it is characterized in that the diameter of phi of the blade of spiral cutting edge 3 top 1 1=8.0 ± 0.022mm, the diameter of phi of blade top 25 3=4.4mm; Blade top 25 is provided with break 6 between blade top 1, the diameter of phi of break 6 2=6.4 ± 0.1mm; Height H=1mm between top 25 blades top 1 of blade.
Between blade top 1 and blade top 25, being provided with a break 6 adding avoids product to occur wedge angle man-hour.The helical angle of debris removal helicla flute 2 and spiral cutting edge 3 is 30 degree.The diameter of phi of blade top 1 1, blade top 25 diameter of phi 3with the size of height H between blade top 25 to blade top 1 all will be determined according to the technical requirement of product.Angle α=90 ° that adjacent two blades are top.
This utility model uses on numerically controlled lathe.
