Abstract
The invention provides a high precision machining method for an X-direction reflection mirror. According to the method, the X-direction reflection mirror formed after rough machining adheres to a clamp and is fixed to a worktable of a ZeeKo seven-axis polishing machine tool; the central position of the X-direction reflection mirror is punched through the dial indicator rotation method; the upper surface of the X-direction reflection mirror is ground through an air bag type polishing head of the ZeeKo seven-axis polishing machine tool; after machining of the upper surface is completed, the 45-degree inclined surface of the X-direction reflection mirror is ground. The method has the advantages of being capable of shortening the production time and improving the production efficiency.
Description
Technical field
The present invention relates to precision processing technology, particularly a kind of X is to the high-accuracy working method of speculum.
Background technology
High-accuracy super-smooth surface manufacture needs to be realized by computer numerical control polishing CNCP technology, and what introduce herein is the CNC Bonnet Too l Polishing lathe of a kind of precision, Zeeko seven axle polishing lathe. it replaces minor diameter abrasive disk to carry out polishing by the special spherical envelope being filled with low pressure gas, function is removed in order to obtain gaussian-shape, air bag not only rotates, also add multipoint swing, air bag can fit tightly with workpiece surface, and it is even to contact region pressure distribution, thus achieve controlled Flexible Manufacture, in polishing process, the air bag axis of rotation and workpiece to be machined local normal have angle, and the precession campaign of similar gyro motion is done around this normal, in contact region, speed profile is average, form the influence function with good characteristic, thus greatly reduce finished surface face shape error, and contact region internal friction power is extended along all directions, surface to be machined texture presents the feature of homogeneity and randomness, thus extremely excellent surface quality is obtained.
Usual Zeeko seven axle polishing lathe is used for the glass planar of polishing heavy caliber, and face shape can reach 1/5th wavelength, and X described herein needs polishing 45 degree of inclined-planes to speculum processing, and face shape to be reached 1/10th wavelength. Therefore the special fixture of design and specific processing parameter is needed to realize with Zeeko seven axle polishing machine tooling X to speculum.
Summary of the invention
It is an object of the invention to provide the high-accuracy working method of a kind of X to speculum, can reduce the production time, it is to increase production efficiency.
For solving the problems of the technologies described above, first X shaping for roughing is adhered on fixture to speculum by the present invention, is fixed on the worktable of Zeeko seven axle polishing lathe; Use dial indicator spinning solution to get the central position of X to speculum, calculate starting point by this central position, then with the gasbag polishing tool grinding upper surface of X to speculum of Zeeko seven axle polishing lathe; After upper surface machines, then grind X to the 45 of speculum degree of inclined-planes.
The diameter of described gasbag polishing tool is 40mm.
Described grinding X is specially to the technical parameter of the upper surface of speculum: rotating speed S is 1800rpm, and entering speed F is 800mm/min, and step pitch �� Z is 0.3mm.
Described grinding X is specially to the technical parameter on the 45 of speculum degree of inclined-planes: rotating speed S is 1800rpm, and entering speed F is 600mm/min, and step pitch �� Z is 0.1mm.
Described fixture is the cuboid that front end has groove structure.
Described adhering method, for utilizing electric iron yellow wax evenly to drop to X to speculum outline edge place, is then cooled to normal temperature.
The surface precision of the inventive method processing optical surface of X to speculum reaches within 1/10th wavelength, compared with hand lapping, reduces the production time, it is to increase production efficiency.
Accompanying drawing explanation
Fig. 1 is the structure iron of the fixture of the present invention;
Fig. 2 is that the present invention X to be processed is to the structure iron of speculum.
