Description

A kind of dressing method of arc-shaped skive
Technical field
The invention belongs to the dressing methods of grinding wheel, and in particular to a kind of dressing method of arc-shaped skive.
Background technique
In recent years, application of the complex curved surface parts (such as optical mirror slip, microstructural mold) in national defence, aerospace field It is more and more extensive, it is mostly part made of the hard brittle materials such as ceramics, optical glass, hard alloy for these, is based on diamond The superfine grinding technology of grinding wheel is the effective means of its processing.The arc-shaped skive of Metal Substrate is with metal for combination Agent, diamond are efficient, high-precision, the long-life the bonded abrasive tool of one kind that abrasive material is prepared, and demand and application may be implemented in it Increasingly extensive and conventional abrasive material (silicon carbide, corundum) grinding wheel is difficult to the high speed of competent various difficult-to-machine materials, efficient, superfinishing Close processing is spherical surface, aspherical, free form surface precision grinding machining important tool.
Although the hardness of arc-shaped skive and intensity are high, with the progress of process, wheel face is still It inevitably wears or blocks, so that grinding force increases, grinding temperature rises, so as to cause grinding trembling and thermal damage, make Workpiece surface integrality is obtained to be affected.In addition, the circular arc working face after abrasion also easily loses correct geometry, thus make At grinding wheel profile errors will directly duplicate workpiece surface, cause workpiece surface precision decline.To be ground wheel face Enough sharpness and correct geometry can be remained in the process, and just periodically it must be modified.
The research of arc-shaped crushing technology is with the extraordinary finishing side such as traditional machine finish method and electric spark, laser Based on method.A kind of patent " swing type hard grinding wheel grinding wheel arc dresser " of Publication No. CN108381398A, which proposes one kind, to repair The method of the arc-shaped grinding wheel of whole various radiuses.Freeing wheel is mounted on electro spindle, realizes pendulum motion by driving device to repair Full circle curved profile, and can realize the compensation of dressing process medium plain emery wheel abrasion loss, but the on-line monitoring of abrasion of grinding wheel and real-time benefit The difficulty repaid is larger, and the contour accuracy of grinding wheel is lower after finishing." a kind of concave curved surface is super for the patent of Publication No. CN103802039A Hard grind material laser finishing device for grinding wheel and method " make full use of numerically-controlled precise lathe high-precision and computer software it is efficient Property, the coordinate correspondence relationship of standard grinding wheel nominal contour each point and grinding wheel to be trimmed is directly established, laser displacement sensor is passed through Concave curved facet wheel profile is scanned, and is compared with the corresponding points of corresponding nominal contour, thus judge whether the point needs to modify, Finishing information can be timely feedbacked, but removes only the high point material of wheel face, abrasive grain does not go out sword, that is, is only applicable to whole Shape.The patent " a kind of grinding wheel double excitation trimming device and dressing method " of Publication No. CN108032222B proposes a kind of using receiving Second, femtosecond laser beam distinguish the method for shaping, dressing parallel grinding wheel, while assisting lateral fluid column stream to alleviate wheel face heat waste Hurt degree.This method can carry out the shaping and dressing process of grinding wheel simultaneously, though it is able to achieve the promotion of dressing efficiency, due to grinding wheel The influence of " airbond " effect leads to the inhibition of abrasive grain metamorphic layer so that grinding fluid is difficult to enter actual dressing area when rotation Effect is not fine.
In relevant document report, for the finishing of arc diamond wheel apex region in perpendicular grinding method, Chen Bing etc. is proposed A kind of method using frotton end face precise dressing grinding wheel section circular arc apex region, the grinding wheel of rotation is with certain feeding speed The GC frotton end opposite grinding of degree and grinding depth and rotation, with the lasting progress of dressing process, grinding wheel installation and abrasion are generated Bias and bounce can constantly reduce, the turn error of grinding wheel drops to 10 μm by 40 μm after finishing.Repairing based on cup emery wheel Whole principle, Ke Xiaolong etc. develop dedicated two axis circular arc wheel dresser, can modify out the gold that arc radius is 30~100mm Hard rock grinding wheel.Zhang Fei tiger et al. has developed oscillating electrode formula electric spark shaving device for modifying arc-shaped grinding wheel, and electrode is around circle Arc profile reciprocally swinging gradually forms arc profile, and wear to electrodes easily compensates, but region of discharge is small between electrode and workpiece, finishing effect Rate is lower.
It can be seen that being studied at present for the finishing of arc-shaped formed grinding wheel, Mechanical Method, electric spark shaving, laser reconditioning There is many deficiencies in method etc., and be suitable for emery wheel dressing more, have no the document or patent for formed grinding wheel dressing at present Report.Therefore, integrate high dressing efficiency, precision, quality, environmental-friendly grinding wheel dressing method there is an urgent need to a kind of and mention High dressing precision, efficiency and quality.
Therefore, this field needs a kind of dressing method of new shaped diamond stone sand wheel.
Summary of the invention
The object of the present invention is to provide a kind of dressing methods of arc-shaped skive, to solve to propose in background technique The extraordinary dressing method such as traditional machine finish method and laser have that dressing efficiency is lower, dressing quality is poor and answers The problem of with being limited in scope.
