Abstract
A precise finishing method of a large abrasive grain diamond grinding wheel relates to processing methods of diamond grinding wheels. The method solves the conventional problem that the conventional method for precisely processing hard and brittle materials is low in efficiency and high in cost. The method comprises the following steps: step 1. placing a square Cr12 steel bloom on a longitudinal magnetic worktable, and controlling a large abrasive grain diamond parallel grinding wheel to carry out plane grinding machining on the Cr12 steel bloom in a transverse feed grinding manner through a numerical control program; and step 2. clamping a finishing shaft with a cup-shaped diamond roller on a clamp fixture, absorbing on the magnetic worktable of a machine tool, and controlling and adjusting the rotating speed of the cup-shaped diamond roller to be 1200-1800r/min by using a frequency converter in a finishing system through the relative motion of a cup-shaped finishing roller and the large abrasive grain diamond parallel grinding wheel 1. The method is used for the precise finishing of the large abrasive grain diamond grinding wheel.
Description
Technical field
The present invention relates to a kind of skive processing method.
Background technology
At present, in the processing of hard brittle material, be earlier with the higher roughing mode of working (machining) efficiency mostly, and then with finished surface semifinishing preferably, carry out precision/ultraprecise with the emery wheel of particulate or particulate again and process at last.Two to three working procedure processing of so continuous usefulness, each operation all will be changed different emery wheels, causes processing cost high, and overall grinding efficiency is low.And it is very little that particulate/particulate emery wheel adds the man-hour chip space, can produce more particle detachment, may not necessarily satisfy the requirement of machining accuracy.And the irregular abrasive particle of wheel face is arranged, and assembly causes periodic finishing with abrasive particle, is difficult to improve working (machining) efficiency.To this situation, if can carry out accurate grinding, need not to change emery wheel so with big abrasive particle skive, can accomplish by roughing to precision machined process, thereby can improve working (machining) efficiency greatly.
In addition, realize the ductility territory grinding of hard brittle materials such as optical glass mostly with resinoid bond or metal anchoring agent diamond wheel.But resin bond wheel is not suitable for heavy load grinding, and the abrasion of grinding wheel rate is high, has limited workpiece surface quality and form accuracy, has caused the variation of abrasive grain layer pattern and composition.Be prone to heating in the metal bonded wheel grinding process, be prone to stopped up, so emery wheel must repeat finishing, reduce grinding efficiency, increase processing cost by abrasive dust.And the plated metal bond in the electroplating abrasion wheel has guaranteed required high contact stiffness and abrasive particle support stiffness, and manufacturing process is simple, small investment, and the abrasive particle projecting height is 1/3 of an abrasive particle diameter.The soldering emery wheel is to utilize the reactive metal element to form chemical metallurgy at the interface at metal solder and abrasive particle to combine; Improved the control intensity of bond greatly to abrasive particle; So only need very thin bond thickness just to be enough to control securely abrasive particle, its exposed height can reach 70%～80%.The standout that abrasive particle is high had both improved the sharpness of diamond grinding sword, had expanded chip space again greatly, and emery wheel is difficult for stopping up, and grinding force, grinding specific energy and grinding temperature all have obvious decline, and the utilization rate of abrasive particle and emery wheel are significantly improved service life.Thereby the application of big abrasive particle grinding wheel can reduce production costs significantly.If can realize satisfied processing effect through effectively controlling machined parameters, then one for the development of grinding technique favourable reference value is provided surely.And big abrasive particle grinding wheel need be repaired it if will realize accurate grinding timely and effectively, and this seems particularly important.
Summary of the invention
The purpose of this invention is to provide a kind of big abrasive particle skive precise dressing method, to solve the problem that efficient is low, cost is high that existing traditional Precision Machining hard brittle material exists.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: said method comprising the steps of: step 1, the big abrasive particle diamond parallel grinding wheel of installation on the precisive plane grinding machine; Square Cr12 bloom is placed on the magnetic worktable; Control the mode flat surface grinding processing Cr12 bloom of big abrasive particle diamond parallel grinding wheel through numerical control program with infeed grinding; Survey big abrasive particle skive turn error, until the turn error value less than 10 μ m;
The present invention has following beneficial effect: the present invention has broken through traditional optical glass processing operation; Big abrasive particle skive is applied in the accurate grinding manufacturing procedure of hard brittle material; Through with Cr12 bloom and cup-shaped diamond roller precise dressing to electroplating abrasion wheel; Thereby reduce electroplating abrasion wheel radially turn error and axial height gradient difference, make that workpiece surface quality is significantly improved after the grinding, can obtain precision machined surface (Ra≤0.02 μ m) efficiently.The present invention has solved a series of difficult problems such as optical glass accurate grinding efficient is low, the emery wheel replacing is frequent to a certain extent, has realized the efficient high-quality optical glass precisive plane processing of big abrasive particle plated diamond grinding wheel.

The specific embodiment one: combine Fig. 1-Fig. 5 that this embodiment is described; Said method comprising the steps of of this embodiment: step 1, the big abrasive particle diamond parallel grinding wheel 1 of installation on the precisive plane grinding machine; Square Cr12 bloom 2 is placed on vertical magnetic worktable; Control big abrasive particle diamond parallel grinding wheel 1 with the mode flat surface grinding of infeed grinding processing Cr12 bloom 2 through numerical control program, survey big abrasive particle skive turn error, until the turn error value less than 10 μ m;
In repairing with Cr12 bloom 2; Owing to adopt the mode of dry grinding, add and produce graphite and iron filings in the dressing process and make the slight clogging of big abrasive particle diamond parallel grinding wheel 1 appearance, accelerated heat accumulation; Also catalysis the wearing and tearing of diamond abrasive grain, effectively reduce the turn error of emery wheel.Carry out in the process in finishing, need in time the emery wheel that clogging is arranged to be carried out dressing with oilstone.Because do not add cooling fluid, so emery wheel can produce certain thermal deformation, and produce the phenomenon of expanding with heat and contract with cold in succession, can be in the improvement that to a certain degree influences the emery wheel turn error.
In repairing with cup-shaped diamond roller 4, cup-shaped diamond roller 4 is a metallic bond, when producing obstruction, with ELID (being online electrolysis) technology it is carried out dressing, to guarantee carrying out smoothly of electroplating abrasion wheel finishing process.This finishing mode need add cooling fluid, to reduce the temperature of machining area, reduces the thermal deformation of emery wheel, helps improving dressing accuracy.The thermal deformation errors that dry grinding produced when this method had also just been avoided Cr12 bloom method for trimming.
