Abstract
The present invention discloses a kind of screw-on cutter radial accuracy grinding method, and milling cutter is mounted on machine tool chief axis, is coloured in each circumferential clearance of milling cutter；Main shaft turns left, and primary feed is completed semifinishing parts groove oral examination and cut；Part notch size is detected, checks blade colored state；It grinds uncolored blade or grinds uncolored blade successively；Trial cut simultaneously repeats aforesaid operations, until part notch size meets technology requirement.The grinding method of the present invention, change traditional milling cutter static accuracy lapping mode, realize the operating accuracy adjustment of milling cutter radial direction, the processing of part high-precision notch can be completed with primary feed, improve part notch milling production efficiency, processing quality is stablized, easy to operate, is suitble to the high-precision notch Milling Process of high-volume part.
Description
Technical field
The present invention relates to field of machining, are specifically a kind of high-precision notch Milling Process suitable for high-volume part
Screw-on cutter radial accuracy grinding method.
Background technology
In aviation, the groove profile part of military secret and civil aircraft is more.The high-precision notch milling of groove profile part is main
By numerically-controlled machine tool milling and plain-milling machine milling, the part notch precision of numerically-controlled machine tool milling is good, stable quality, but numerical control machine
Bed milling is carried out in a manner that row is cut, and piece surface can form wave crest, and reciprocating stroke is more, and high processing costs use plain-milling machine
Unstable using the deep trouth of metal saw milling or the shallow slot part notch quality of slotting cutter milling, feed is often, it is necessary to grasp
Author has skilled professional skill.
It is that notch processing high efficiency is promoted to complete the high-precision processing of part shallow slot using slotting cutter radial dimension primary feed
A kind of shortcut, milling cutter by abrasive machine reconditioning processes far from the part for meeting high-precision notch, it usually needs operation
Person grinds.
The slotting cutter of general processing notch is right spiral milling cutter, and Conventional milling methods are measurement milling cutter radial dimensions, then
Each blade is uniformly ground, finally reaches part notch theoretical value, the drawbacks of this static state grinding method is that milling is not determined in advance
The radial beat eccentricity of bed, less can determine that the amount of grinding of each blade, can not keep the uniformity of circumferential clearance, cause milling cutter
Radial dimension grinding precision is not known, and tool life is poor.
The content of the invention：
For solution more than technical problem, the present invention provides a kind of screw-on cutter radial accuracy grinding method, this method can allow
Once the processing of part high-precision notch is completed in feeding to milling cutter on milling machine, and processing quality is stablized, and surface roughness is high, operation letter
It is single, it is suitble to the high-precision notch Milling Process of high-volume part.
A kind of screw-on cutter radial accuracy grinding method of the present invention, comprises the following steps：
A, close to the milling cutter diameter of part notch size, cutter tooth number is three teeth or four teeth for selection；
B, milling cutter is mounted on machine tool chief axis, is coloured in each circumferential clearance；
C, main shaft turns left, and primary feed is completed semifinishing parts groove oral examination and cut；
D, part notch size is detected, determines milling cutter radial direction amount of grinding；
E, check each blade colored state, determine each blade grinding order；
F, main shaft is turned right, and rotating speed 30r/min grinds uncolored blade or grinds uncolored blade successively；
G, milling cutter relief angle is ground using blue grind stone, blue grind stone need to be impregnated with kerosene, and oilstone dips in machine during grinding
Oil；
H, grinding oilstone is close to circumferential clearance face and extends to blade lower end along blade helical angle from blade upper end, keeps circumferential clearance
It is constant；
I, trial cut and repetition b-h steps, until milling cutter radial accuracy meets part notch size；
J, grind after the completion of, main shaft turn left, then with aluminum waste material along blade helical angle at each blade knife edge from blade lower end
It is gently scraped once to blade upper end.
The screw-on cutter radial accuracy grinding method of the present invention, changes traditional milling cutter static accuracy lapping mode, real
The operating accuracy adjustment of milling cutter radial direction is showed, the processing of part high-precision notch can be completed with primary feed, improves part notch
Milling production efficiency, processing quality is stablized, easy to operate, is suitble to the high-precision notch Milling Process of high-volume part.
Description of the drawings
Fig. 1 is the schematic diagram of screw-on cutter；
In figure：1. 6. blade upper end 7. of the first the 3rd 5. cutter body of the 4th blade of blade 4. of 2. second blade 3. of blade
Blade lower end.
Specific embodiment
See Fig. 1, a kind of screw-on cutter radial accuracy grinding method of the invention, grinding steps are as follows：
A, close to the milling cutter diameter of part notch size, cutter tooth number is four teeth for selection；
B, cutter body 5 is mounted on machine tool chief axis, is coloured in each circumferential clearance, while divided respectively in circumferential clearance
The first blade 1, the second blade 2, the 3rd blade 3, the 4th blade 4 are not marked to be distinguished with showing；
C, main shaft turns left, and primary feed is completed semifinishing parts groove oral examination and cut；
D, part notch size is detected, if notch size is more than technical conditions 0.05mm, then radially total amount of grinding is milling cutter
0.05mm；
E, each blade colored state is checked, circumferential clearance seamed edge that decoloration width is more big, is the first blade 1 of grinding, according to
This determines each blade grinding order, colours and constant does not grind；
F, main shaft is turned right, rotating speed 30r/min, grinds uncolored blade in order, blade amount of grinding is with blade grinding order by most
Minimize greatly；
G, milling cutter relief angle is ground using blue grind stone, blue grind stone need to be impregnated with kerosene, and soaking time is when 24 is small
More than, oilstone dips in machine oil during grinding；
H, hold grinding oilstone and be close to circumferential clearance face and extend to blade lower end 7 along blade helical angle from blade upper end 6, keep pressure
Power is uniform, keeps circumferential clearance constant；
I, trial cut, and repeat b-h steps again, until milling cutter radial accuracy meets part notch size；
J, grind after the completion of, main shaft turn left, with aluminum waste material along blade helical angle at each blade knife edge from blade lower end 7 to
Blade upper end 6 is gently scraped once, eliminates the microcosmic saw-tooth on the knife edge.
