Abstract

The invention discloses a process for producing a ceramic grinding table. The process comprises the following steps: (1) prefabricating a glass material; (2) finely grinding glass powder; (3) mixing; (4) producing green bodies; (5) drying; (6) sintering; (7) molding the grinding table; (8) bonding the grinding table to a basal body; and (9) grinding to form the finished product. In the process for producing the ceramic grinding table, a ceramic binding agent is utilized to replace a traditional bronze binding agent to produce a diamond grinding table, and compared with a diamond grinding table produced by utilizing the bronze binding agent, the ceramic binding agent per se has the characteristics of good brittleness and self-sharpening; in a grinding process, due to the good self-sharpening, diamond in the upper layer quickly falls off after being blunt so that the diamond in the lower layer is exposed to form a new sharp grinding blade, the grinding force can be maintained for a long time, and the grinding table has good sharpening in grinding.

Description

Produce the technology of ceramic millstone
Technical field
The present invention relates to a kind of manufacture field of diamond disk, especially relate to a kind of technology of production ceramic millstone of ceramic bond.
Background technology
Crisp and hard materials such as sight glass, magneticsubstance, sapphire are widely used in mobile phone glass, precision electronic element, precision optics and high-grade Watch glass, and owing to itself quality high firmness and brittle characteristics, the difficulty of attrition process is very big; The earliest be to carry out attrition process with classic polishing, promptly grind with free abrasive dust, its shortcoming is that the consumption of abrasive dust is big; Most of abrasive dust is not utilized, and produces a large amount of dust and sewage, and is very serious to the pollution of environment; Along with the progress of grinding technique, the attrition process of said material is developed and be used for to the abrasive disk of bronze binding agent, and the application of bronze binding agent mill becomes free abrasive particle grinding and is the fixed grain grinding; Increased the utilization ratio of abrasive material greatly, the pollution of no dust and sewage in the grinding process, but in use the shortcoming of bronze dish manifests gradually; Because its material softer is tough, the easy blocking mill, the self-sharpening of itself is bad; The very fast passivation of mill, grinding efficiency descends, and the dressing difficulty.
Summary of the invention
To problem set forth above, the object of the invention is to provide a kind of mill of ceramic bond to substitute the bronze binding agent mill, than bronze binding agent; Ceramic bond itself enbrittles and the good characteristics of self-sharpening, in grinding process, because self self-sharpening is good; The upper strata diamond comes off behind blunt very soon, makes lower floor's diamond exposure; Form new sharp cutting edge, grinding force can be kept lastingly, show in the grinding to be exactly that the mill sharpness is good.
The present invention realizes through following technical measures, a kind of technology of producing ceramic millstone, and its process step is:
(1) prefabricated frit: with chemical pure SiO 2, B 2O 3, Al 2O 3, Li 2O, K 2O, Na 2O starting material thorough mixing is founded in Cinker clew furnace, and 1200~1600 degrees centigrade of glass melting temperatures are incubated two hours, come out of the stove the back Water Quenching get final product frit;
(2) fine grinding glass powder: frit is through ball milling, and wearing into granularity is 200~300 purpose glass powder;
(3) mix: diamond is added in the glass powder and adds Z 150PH mix after wetting;
(4) generate green compact: adopt mould to be pressed into base;
(5) oven dry: with green compact 100~140 degrees centigrade of oven dry;
(6) sintering: bury sand sintering in 600~900 degrees centigrade of resistance furnaces;
(7) mill moulding: sintering is come out of the stove after accomplishing, the finishing shaping;
(8) mill bonds on the matrix;
(9) mill is processed into finished product.
Concrete, the weight proportion of each component is in the prefabricated frit of said step (1): SiO 240~55, B 2O 310~18, Al 2O 35~12, Li 2O 4.5~10, K 2O 2~6, Na 2O 4~12.
As a kind of optimal way, glass melting temperature is 1450 degrees centigrade in the prefabricated frit of said step (1).
As a kind of optimal way, the granularity of the glass powder of wearing in said step (2) the fine grinding glass powder is 240 purposes.
As a kind of optimal way, in said step (5) oven dry with green compact 120 degrees centigrade of oven dry.
As a kind of optimal way, bury sand sintering in 700 degrees centigrade of resistance furnaces in said step (6) sintering.
The present invention is directed to the characteristics of traditional bronze binding agent mill self-sharpening difference, use ceramic bond instead, in order to improve work-ing life; Also improved the physical strength of wedding agent, increased wedding agent to durability of diamond, to the high characteristics of ceramic bond refractoriness; Through changing the wedding agent proportion of raw materials, adopt the wedding agent of clay-quartz-boron glass system, because the boron glass refractoriness is on the low side relatively; Through a series of experiment; Find suitable formula rate, both satisfied the requirement of refractoriness, satisfy the requirement of self-sharpening again.
To the formation that roll to scratch, the present invention has designed the flexible resin packing layer between pottery, is mounted to the flexible resin interlayer rapidly after making diamond drop-off, avoids it on workpiece, to continue to roll and form the scuffing of rolling.
Compare with free abrasive dust grinding, its efficient significantly improves, and does not produce dust and contaminated wastewater, compares with bronze sintering pan, and its self-sharpening is good, and grinding efficiency is high, and the finishing number of times is few, and does not produce the scuffing of rolling.
Embodiment
Below in conjunction with embodiment the present invention is done further explain.
A kind of diamond grinding head production technique of ceramic bond, its process step is:
(1) prefabricated frit: with chemical pure each component weight proportion be: SiO 240~55, B 2O 310~18, Al 2O 35~12, Li 2O 4.5~10, K 2O 2~6, Na 2O 4~12SiO 2, B 2O 3, Al 2O 3, Li 2O, K 2O, Na 2The starting material thorough mixing of O is founded in Cinker clew furnace, and 1450 degrees centigrade of glass melting temperatures are incubated two hours, the back hardening of coming out of the stove handle get final product frit;
(2) fine grinding glass powder: frit is through ball milling, and wearing into granularity is 240 purpose glass powder;
