A kind of glass may further comprise the steps when it is characterized in that preparing with the preparation method of diamond chamfering polishing wheel: the first step obtains compound after above each raw material mixed in proportion;
In second step, it is hot-forming in the mould that compound is packed into, and hot pressing is: hot pressing temperature is 235 ℃, and hot pressing time is 30～40 minutes, and hot pressing pressure is 6MPa; Put into baking oven heating carrying out regelate after the demoulding again, heating process is: at first freely heated up before 200 ℃, insulation is 1 hour when arriving 200 ℃, then between 200～215 ℃, freely heat up, insulation is 1 hour when arriving 215 ℃, freely heats up at 215～230 ℃ then, and insulation is 5 hours when arriving 230 ℃, stop heating at last, treat the stock of nature cooling back taking-up abrasive material;
The 3rd step, after surface treatment, bonding the stock of above-mentioned abrasive material with the matrix that adopts bakelite to make, obtain finished product at last.
The present invention selects two kinds of micro powder grade abrasive materials and wear-resisting bond prescription for use, polishing scratch exquisiteness to glass mill chamfering the time, and promptly chamfering is once finished with the polishing throwing is bright, the degree of depth of chamfering is changeable through adjusting, the linear velocity during chamfering is fast, grinding resistance is little, and current of electric is little and steady, power saving.Service life while is very long, saves to shut down and changes the emery wheel time.The combination property price is higher than very.Wherein, matrix adopting phenolic moulding powder is injection molded with plastic injection equipment, and production efficiency height and cost are very low.
That the present invention has is simple and reasonable, flexible operation, chamfering and polishing are thrown and brightly once finished, cost of manufacture is low, the characteristics of long service life.
Description of drawings
Fig. 1 is the cross-sectional structure schematic diagram of one embodiment of the invention.
Among the figure: 1 is matrix, and 2 is abrasive material.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
First embodiment
Referring to Fig. 1, this glass diamond chamfering polishing wheel, comprise matrix 1 and abrasive material 2, abrasive material 2 is formed by the feedstock production of following percent by volume: the diamond 10～15% that 800 orders are above, the carborundum 10～15% that 600 orders are above, the above carborundum 5～10% of polyimide resin powder 55～65%, 325 purpose copper powders 5～10%, 1000 orders that 500 orders are above.
Glass may further comprise the steps in the preparation with diamond chamfering polishing wheel:
The first step obtains compound after above each raw material mixed in proportion;
In second step, it is hot-forming in the mould that above-mentioned compound is packed into, and hot pressing is: hot pressing temperature is 235 ℃, and hot pressing time is 30～40 minutes, and hot pressing pressure is 6MPa; Put into baking oven heating carrying out regelate after the demoulding again, heating process is: at first freely heated up before 200 ℃, insulation is 1 hour when arriving 200 ℃, then between 200～215 ℃, freely heat up, insulation is 1 hour when arriving 215 ℃, freely heats up at 215～230 ℃ then, and insulation is 5 hours when arriving 230 ℃, stop heating at last, treat the stock of nature cooling back taking-up abrasive material;
The 3rd step, after surface treatment, bonding the stock of above-mentioned abrasive material with the matrix 1 that adopts bakelite to make, obtain finished product at last.
Glass after the shaping is outer diameter D=130 with the abrasive material specification of diamond chamfering polishing wheel, ring width W=20, thickness T=20, about about 120 yuan of the cost of manufacture of each chamfering polishing wheel, is 360 * 240 * 3 glass mill chamfering 0.55 * 0.55 with this chamfering polishing wheel to specification, linear velocity during chamfering is more than 4.5 meters/minute, and below 0.8A, current of electric can reach more than 10 days service life always.And adopt a kind of chamfering wheel (be commonly called as stone wheel) of other manufacturer production at present, its abrasive material specification is outer diameter D=129, ring width W=20, thickness T=30, about about 30 yuan of the cost of manufacture of each chamfering wheel grinds chamfering 0.45 * 0.45 for the glass of specification 360 * 240 * 3 with this chamfering wheel, and the linear velocity during chamfering is about 3 meters/minute, current of electric is always at 1～1.2A, and service life was less than 2 days.Through contrast, this product has higher operating efficiency, for original 1.5 times, has lower operating current.
By the 10 days minimum service life of a diamond chamfering polishing wheel, maximum service life (MSL)=5*2 days=10 days of five stone wheel, on the basis in roughly the same service life, compare, about about 120 yuan of the cost of manufacture of a diamond chamfering polishing wheel, about the about 5*30=150 of the cost of manufacture unit of five stone wheels, this product has lower cost of manufacture, and can reduce centre four replacing time and staff when using the stone wheel, therefore, this product has lower use cost.
Second embodiment
All the other are not stated part and see first embodiment, no longer repeat.
The 3rd embodiment
All the other are not stated part and see first embodiment, no longer repeat.
