Abstract
The invention discloses a kind of three swords aluminium milling cutter, including knife bar and cutter head, cutter head is provided with three side cutting edges and three corresponding end swords, side cutting edge is in the shape of a spiral, the helical angle of side cutting edge is 40~45 °, sword is held to include cutting edge, arc transition sword and inner concave, cutting edge is connected with inner concave by arc transition sword, the relief angle of cutting edge is 14 °, the relief angle of arc transition sword is 30 °, axially arranged one cylindrical chip area inside cutter head, the section circle of chip area is inscribed within described end sword.The present invention is simple in construction, and end sword uses the structure of cutting edge, arc transition sword and inner concave, friction can be effectively reduced, so as to extend cutting-tool's used life.The axially arranged cylindrical chip area in inside of cutter head, is conducive to chip removal and holds to consider to be worth doing, accelerates cutting speed and improves the quality of finished surface.
Description
Technical field
The present invention relates to a kind of milling cutter, more particularly to a kind of three swords aluminium milling cutter.
Background technology
In machining, cutter is the indispensable critical piece of machine tooling, and the quality of cutter quality has influence on itself
Service life, also have influence on the quality and production efficiency of machining.When being processed to aluminium, because aluminium hardness
It is softer, knife is easily glued in cutting, causes cutting resistance big, tool wear is serious, cutting speed is slow, the problems such as chip removal has some setbacks.
The content of the invention
It is an object of the present invention to overcome the above-mentioned technical problems, and to provide a kind of three swords aluminium milling cutter, it can be fully solved
Above-mentioned technical problem.
The technical scheme for solving above-mentioned technical problem is as follows：
A kind of three sword aluminium milling cutters, including knife bar and cutter head, described cutter head are provided with three side cutting edges and three phases
Corresponding end sword, in the shape of a spiral, the helical angle of the side cutting edge is 40~45 °, described end sword bag to described side cutting edge
Cutting edge, arc transition sword and inner concave are included, described cutting edge is connected with inner concave by arc transition sword, described cutting
The relief angle of sword is 14 °, and the relief angle of described arc transition sword is 30 °, axially arranged one cylindrical chip removal inside described cutter head
Groove, the section circle of described chip area is inscribed within described end sword.
The section circular diameter of described cylindrical chip area is 0.4~0.45 times of tool bit diameter.
Described knife bar end is provided with chamfering.
Described bit interface is provided with TiAlN coating.
The present invention is simple in construction, and end sword uses the structure of cutting edge, arc transition sword and inner concave, can effectively reduce and rub
Wipe, so as to extend cutting-tool's used life.The axially arranged cylindrical chip area in inside of cutter head, is conducive to chip removal and holds to consider to be worth doing, plus
Fast cutting speed and the quality for improving finished surface.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the invention；
Fig. 2 is side view of the invention；
