02;Bit body 02 is equipped with a plurality of spiral mounting portion 021;Each spiral mounting portion 021 is from top to bottom and along spiral side
To being disposed with multiple blades 03 (blade 03 is fixedly mounted by screw 023);The setting of cooling-lubricant sprue 1 is connecting
Knife handle 01 simultaneously extends in bit body 02;Cooling-lubricant secondary channels 2 be it is a plurality of, a plurality of cooling-lubricant secondary channels 2 are located at
In each spiral mounting portion 021, and it is adapted with the shape of spiral mounting portion 021;
Rake face cooling-lubricant runner 21 and the cooling profit of flank are respectively arranged with above and below each blade 03
Synovia runner 22;The entrance of rake face cooling-lubricant runner 21 is connected to the cooling-lubricant secondary channels 2, and rake face is cooling
The rake face of the outlet face blade 03 of lubricating fluid runner 21;The entrance of flank cooling-lubricant runner 22 and the cooling profit
Synovia secondary channels 2 are connected to, the flank of the outlet face blade 03 of flank cooling-lubricant runner 22;
It is cooling to connect knife handle 01, bit body 02, cooling-lubricant sprue 1, cooling-lubricant secondary channels 2, rake face
Lubricating fluid runner 21 and flank cooling-lubricant runner 22 are all made of the mode machine-shaping of 3D printing.
Cooling-lubricant flows to cooling and lubricating corresponding to each spiral mounting portion 021 by cooling-lubricant sprue 2
In liquid secondary channels 2, cooling-lubricant is delivered to the rake face cooling-lubricant of each blade 02 by cooling-lubricant secondary channels 2 again
Runner 21 and flank cooling-lubricant runner 22 realize the cooling and lubricating to the forward and backward knife face of each blade of square shoulder milling cutter.
Embodiment 2
As shown in Fig. 2, on the basis of embodiment 1, it is exactly in square shoulder that there are also further optimization designs by the present invention
Milling cutter is additionally provided with cooling-lubricant working area 3, and cooling-lubricant working area 3 includes being arranged in 1 He of cooling-lubricant sprue
Matrix 31 between cooling-lubricant secondary channels 2, matrix 31 are equipped with from its center to whole outer surfaces and are connected to multiple hole (holes
The diameter of gap is less than the diameter of cooling-lubricant secondary channels).Cooling-lubricant passes through the cooling profit of the flow direction of cooling-lubricant sprue 1
Synovia working area 3 enables cooling-lubricant cooling-lubricant before cutter prepares cutting to be kept in the position, side
Shoulder milling cutter starts cooling-lubricant after being cut can be by cooling-lubricant secondary channels under the action of pressure and centrifugal force
