Step 4: the compound that step 3 obtains fills with progressive die tool, inserts refrigerating chamber.
Step 5: according to purposes, selective temperature and time, is frozen into sorbet wheel by the mixture cold in mould.
Step 6: as needed processing, open mould, takes out sorbet wheel, then is put into and finishing machine carries out processing and repair.
Beneficial effect of the present invention
1, the present invention can process and process the material that can not generate heat, ensure that workpiece to be machined is not burnt, not metachemistry react.
2, the present invention also can replace general emery wheel to use, and because water is cheap, thus reduces the production cost of emery wheel.
3, the waste material split away off after the present invention's use, after can dissolving, then makes sorbet wheel again, recycles.
4, present invention process is simple, and all water is nonpoisonous and tasteless with abrasive particle, but shop worker oneself just oneself manufactures in refrigerator with a mould.
Detailed description of the invention

Below in conjunction with raw materials used character and embodiment, the present invention will be further described
Water is liquid, and be suitable for adding abrasive particle and mix, water, below zero degrees celsius, will become solid ice.Pure water is non-icing, but after adding abrasive particle, because abrasive particle can as the starting point of icing crystal structure, just the ice formed for pure water.
Ice is water white solid, and main by hydrogen bond action between molecule, lattice structure is generally hexahedron, but can have other lattice structures in response to different pressures.Its fragility and hardness are suitable for the bonding agent done in grinding tool.
Pure ice Morse hardness is at different temperatures: 0 DEG C is 1 ~ 2, and-15 DEG C is 2 ~ 3, and-40 DEG C is 4, and-50 DEG C is 6.
Have the special construction of hydrogen bond association between hydrone, water becomes solid ice below zero degrees celsius, and ice has tetrahedral crystal structure.This tetrahedron is formed by hydrogen bond, is the relaxed configuration of an open type, because five hydrones can not account for whole tetrahedral volume, in ice, hydrogen bond connects these tetrahedrons, becomes as a whole.This Orienting ordered arrangement formed by hydrogen bond, space availability ratio is less, accounts for 34%, therefore the density of ice is less, and be about that four degrees celsius is aqueous water 9/10.
A large amount of hydrogen bonds has been broken during ice-out, entirety is made to turn to tetrahedron group and fragmentary less " water molecule group ", therefore aqueous water not resembled ice be ordered arrangement completely, but have lack of alignment to a certain degree, namely fixing the distance between hydrone does not resemble in ice, H2O molecule can be entered in another crystallite by a tetrahedral crystallite and go.Intermolecular like this space is reduced, and the relative ice of density just increases.
Pure water, because not having impurity thing, can build-up ice equably, makes ice solidness everywhere strengthen and balance.
After pure water magnetization, the neat rule of hydrone row example, the ice of forming, its crystal structure is firmer.
Cut and grind emery wheel used, need certain hardness, but also certain fragility will be had, and can fall with the old Grain Falling Off damaged in time, the sorbet wheel produced with magnetized drinking water, add the hardness of sorbet wheel, the fragility that ice itself has can meet cutting and grind the condition of emery wheel used.
Some workpiece itself are softer, not high to the hardness requirement of emery wheel, and require that emery wheel fragility is good, abrasive particle easily comes off, so can add 1 NaCl in pure water, reach requirement, addition is larger, and the more crisp abrasive particle of sorbet wheel more easily comes off.In water, add NaCl to slow down the icing rate of water, because the free molecule in salt solution is more, so strong compared with light water of the activity of salt hydrone, make the apparent freezing point of salt solution lower than light water, light water generally freezes at zero degree, but salt solution just can will freeze in subzero.
Some workpiece, need polishing, so it is soft to need sorbet to take turns, at this moment can add some sodium metasilicate, addition is larger, and flexibility is better.
Example: a kind of sorbet wheel, it comprises, 40 kg of water, 60 kilograms of carborundum.
40 kg of water are generated by distilled water generator, are 100% pure water, and 60 kilograms of carborundum are No. 120 green silicon carbide abrasive particles.
60 kilograms of carborundum are No. 120 green silicon carbide abrasive particle clean water three times, for the last time with 100% pure water cleaning.
40 kg of water and 60 kilograms of carborundum mix, and insert in magnetizer and carry out orientation magnetization.
Water after above-mentioned magnetization and silicon carbide abrasive particles compound are injected grinding wheel die.
At ambient pressure, reduce temperature around mould to negative 30 degrees Celsius, and tool mould does not stop to do 360 degree and rolls up and down, ensures that water and abrasive particle are uniformly distributed.
Open mould, take out sorbet wheel.
Example: francium, it is a kind of metal, due to its instability and rare, people start gradually to recognize it and it compound application and special using value widely, for example: it is for the research field of biology and atomic structure, and francium there has also been certain practicality to cancer diagnosis and treatment.But the fusing point of francium only has 21.8 degrees Celsius, the fusing point of some compounds is not high yet, due to unstability, see that heat will become another kind of material, so when processing process, general emery wheel cannot use, and sorbet wheel can carry out various cutting, milled processed to it.
Magnetized drinking water sorbet is taken turns, and under the environment of negative less than 30 degrees Celsius, general emery wheel can be replaced to use, thus reduce the processing cost of workpiece.
Manufacture technology of the present invention is simple, and when requirement condition is not high, mould also as the bonding agent of sorbet wheel, can be inserted in domestic refrigerator by general water, just can produce sorbet wheel.
