Description
Technical field
The utility model relates to delicate machine tools technical field, in particular to a kind of three sword of alloy leads to handle aluminium milling cutter.
Background technique
Milling cutter is for Milling Process, the rotary cutter with one or more cutters tooth.Milling cutter each cutter tooth at work
The surplus for successively intermittently cutting workpiece is mainly used for processing plane, step, groove, forming surface and cutting work on milling machine
Part etc..Rose cutter in milling cutter is assemblied on milling machine for the various curved surfaces of milling, the cutter of arc groove.
Cylindrical milling cutter is for processing plane on horizontal milling machine.Cutter tooth is distributed on the circumference of milling cutter, is divided into directly by tooth form
Tooth and two kinds of helical tooth.It is divided to bastard and two kinds of serration by the number of teeth.The helical tooth heavy-duty milling cutter number of teeth is few, and cutter tooth intensity is high, and it is empty to hold bits
Between it is big, be suitable for roughing；Fine-tooth cutter is suitable for finishing.
It is being machined, such as in CNC processing, is generally requiring to carry out preparatory processing to aluminium using milling cutter, milling is produced
The general configuration of product, to realize that stablizing for milling cutter processes and prevent from damaging, it is necessary to rationally anterior angle, relief angle and the spiral shell of setting cutter head
Swing angle.
Utility model content
Based on this, for the prior art, the utility model provides a kind of logical handle aluminium milling cutter of three sword of alloy, which sets
Meter is novel, structurally reasonable, by the reasonable setting of cutter head anterior angle, relief angle and rotation angle, can realize well to the thick of aluminium
Processing.
The technical solution of the utility model is as follows:
A kind of logical handle aluminium milling cutter of three sword of alloy, including knife handle and cutting portion, the cutting portion include central spindle and are in spiral shell again
Three cutting edges of shape distribution are revolved, described central spindle one end is connect with knife handle, and the cutting edge is set around the outer surface of central spindle, described
End sword is provided on the end face of cutting portion, the end sword includes that the first processing sword and second process sword, the cutting edge and axis
Between form spiral angle, the first processing sword and central spindle radial diameter extended line form anterior angle, the second processing sword with
Relief angle is formed between axis.
Preferably, the cutting portion diameter is identical as shank diameter, may customize according to different needs as 4 ~ 14mm, tolerance
Guarantee within 0 ~ -0.01mm.
Preferably, the spiral angle formed between the cutting edge and axis is 42.52 °.
Preferably, the anterior angle that the first processing sword and central spindle radial diameter extended line are formed is 18 °.
Preferably, the relief angle formed between the second processing sword and axis is 10 °.
Preferably, the cutting portion length is 0.3 ~ 0.4 times of milling cutter length.
Preferably, the milling cutter selects alloy material.
The utility model has the following beneficial effects: the utility model is novel in design, and it is structurally reasonable, pass through cutter head anterior angle, relief angle
With the reasonable setting of rotation angle, the roughing to aluminium can be realized well.

Specific embodiment
It is existing in order to make technological means of the utility model, creation characteristic, reach purpose and means are easy to understand
The utility model is being described in further detail in conjunction with attached drawing.These attached drawings are simplified schematic diagram, only with signal side
Formula illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
Referring to Figure 1, a kind of three sword of alloy leads to handle aluminium milling cutter, including knife handle 1 and cutting portion 2, and the cutting portion 2 wraps again
Three cutting edges 22 for including central spindle 21 and being spirally distributed, described 21 one end of central spindle are connect with knife handle 1, the cutting edge 22 around
Set on the outer surface of central spindle 21, end sword 3 is provided on the end face of the cutting portion 2, the end sword includes the first processing 31 He of sword
Second processing sword 32, forms spiral angle a between the cutting edge 22 and axis, the first processing sword 31 and central spindle are radially straight
Diameter extended line forms anterior angle b, forms relief angle c between the second processing sword 32 and axis.
Specifically, the 2 diameter a of cutting portion is identical as 1 diameter of knife handle, may customize according to different needs as 4 ~ 14mm,
Tolerance guarantees within 0 ~ -0.01mm.
Specifically, the spiral angle b formed between the cutting edge 22 and axis is 42.52 °.
Specifically, the anterior angle c that the first processing sword 31 and central spindle radial diameter extended line are formed is 18 °.
Specifically, the relief angle d formed between the second processing sword 32 and axis is 10 °.
Specifically, the 2 length e of cutting portion is 0.3 ~ 0.4 times of milling cutter length f.
