Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Put the first edge on a knife or a pair of scissors an embodiment of milling cutter, including knife bar 1 for the centre of the utility model referring to Figures 1 and 2, setting in the middle part of knife bar
Knife bar for cutting portion 2, cutting portion both ends is set as clamping shank 3.Cutting portion is set in the intermediate position of entire knife bar, is adding
The clamping shank at working hour both ends has preferable integral rigidity, increases that the effective sword of cutting is long, and the increase of sword length is i.e. effective to be increased
Add milling depth, improved processing efficiency, can once complete the product processing of larger depth.
Above-mentioned cutting portion includes the blade 4 being axially arranged along knife bar, and the product end surface after milling is smooth, blade front end
It is provided with chip space 5, for the clast after milling to be discharged, blade rear end is provided with cutting edge clearance angle 6, plays effective evacuation.
In one implements, cutting portion includes the blade being arranged along knife bar radial direction and spiral, can have stronger milling strong
Degree, blade is hardly damaged, and blade front end is provided with chip space, and for the clast after milling to be discharged, blade rear end is provided with cutting
Edge clearance angle plays effective evacuation.
The material of knife bar is wolfram steel, and the tensile strength of wolfram steel is at least 3900 Ns/square millimeter so that is disliked in high-speed and high-temperature
It still can be worked normally under bad cutting state.
Insulation protection film can also be coated with by cutting cutting portion surface, and the coating thickness of insulation protection film is 3-5 nanometers, heat-insulated
The hardness of protective film is HV3700.Physical vapour deposition (PVD) painting may be used in above-mentioned coating and ion sputtering layer technology, process are above-mentioned
