Rubs truncates the tool to be called for rubs has Rubs has solidifiesrubs has, spreads attaches rubs has and ultra hardly rubs has threebig series Respectively has the characteristic, the independentexistence, each has its strong points, uses in the various countriesnational economy Except that spreads attaches rubs has sets up besidein addition the chapter narration, the here only to solidifies rubshas makes the brief introduction
1. solidifies rubs has
Solidifies rubs has is (rubs with the grinding compoundtruncates material) to make with the cement has the certain shape andcertainly rubs truncates the ability the tool
Solidifies mark demonstration which rubs has:
Shape size grinding compound granularity cement degree of hardnessorganizes 35M/S GB/T2485
Shape code number
300×50×75 grinding compound type grinding compoundgranularity
The cement rubs has degree of hardness
The organization number highest working speed rubs has theengineering factor
In standard number
Except that the highest working speed and rubs has outside thestandard number which the engineering factor is at, other each itemfor solidifies the characteristic which rubs has Solidifies grindingcompound which rubs has already (1)th specify in this article Thegrinding compound granularity refers to the grinding compound thickthin size under, solidifies the grinding compound which rubs has touse a series of standards, these 7 characteristics rested on in 1998the national grinding compound to rub have the standardizationtechnical committee to establish in the mechanical industry standardwhich was published by the Chinese publishing house each stipulationThis besides to solidifies degree of hardness cement and theorganization three characteristics which rubs has performs thenarration, other no longer give unnecessary detail
(1) degree of hardness:
Here degree of hardness is refers solidifies rubs has under theexogenic process, the cement and the grinding compound unionintensity, thickly subdivides according to the granularity do not usesand-blasts the sclerometer and the Luo river hardness test Degree ofhardness minute ultra soft (ultra soft 1, ultra soft 2), soft (soft 1,soft 2), center soft (center soft 1, center soft 2), center (center 1,center 2), center hard (center hard 1, center hard 2, center hard 3),hard (hard 1, hard 2), ultra hard (ultra hard 1, ultra is hard 2) andso on 7 big levels altogether 15 small levels
(2) cement:
The cement is refers solidifies rubs has each kind of cement and thegrinding compound caking material Solidifies rubs has usually usesthe ceramics, the resin, the rubber, 菱苦土 four big categoriescements. These four kind of cements rub the proportion by the ceramiccement which has to be biggest. The ceramic cement main material hasthe clay, the feldspar, the loess, 石英石 and so on the compositionaccording to the different grinding compound, the different use andthe different facture (pours or suppression) and so on the differentceramic cement The resin cement mainly is the phenol aldehyde typeresin, divides the powdery resin and the liquidity resin two bigkinds, also is the basis different facture and the different usedivides into each kind of different resin cement The rubber bond atpresent uses the man-made butylbenzene rubber, Ding Najiao and theliquid rubber three big kinds, is different and the use according tothe facture different divides into each kind of different rubbercementing agent. 菱苦土 the cement main material has the magnesiaand the magnesium chloride two kind of materials composes, mainly usesin 细粒度 the grinding compound to make the fine processing use
Each kind of cement code number as follows:

Cement name cement code number
Ceramic cement V
Resin cement B
Rubber bond R
菱苦土 cement Mg
(3) organizes:
The organization is refers solidifies rubs has the volume which thegrinding compound holds, % compares the expression by the weight Theusual organization in rubs has in the sign not to demonstrate, whenmakes when supposes the system formula, self-control by Arabic numeralexpression Namely numeral smaller, organization looser, namelysolidifies rubs has the grinding compound ratio less, otherwisedigital bigger organization tighter, occupies 磨粒 the ratiorecovers. are many Usual organization number from 0-12 altogether 13organization numbers
2nd, spreads attaches rubs has
Spreads attaches rubs has is refers to the cementing agent torub the grinding compound adherency on to be possible the winding basematerial has, also called the flexibility rubs has
Spreads attaches rubs has has nine big characteristics:
Base material type - base material processing - grinding compound type- grinding compound granularity -
Plants the granulated substance density - cementing agent type- caking intensity - shape - size
砂带 spreads attaches rubs has please sees also notebookarticle third.
3rd, ultra hardly rubs has
Ultra hardly rubs has is refers to the servant to create rubshas, is rubs has another big series which the diamond or the cubicboron nitride ultra hard grinding compound makes
Ultra hardly rubs has has the following several characteristics andthe mark

Density
Cement
Granularity
Grinding compound trademark
Rubs 粒层 thickness
Aperture
Total thickness
Diameter
Shape code number
Above the characteristic and the mark deferred to in 1998 thenational grinding compound to rub has the standardization technicalcommittee to establish in the Chinese mechanical industry standardwhich was published by the Chinese publishing house each standardstipulation
About density: With solidifies the organization number more or lessthe same which rubs has, but in ultra hardly rubs has symbolizedshould mark The so-called density is refers ultra hardly rubs has ineach cm3 volume to contain the ultra hard grinding compound a gramnumber, by % number expression
Density code number as follows:
Code number grinding compound content (g/ cm3) density
250.22 25%
500.44 50%
750.66 75%
1000.88 100%
1501.32 150%

About cement: Is refers ultra hardly rubs has the cementcategory which the institute uses
Cement code number as follows:

Cement cement code number
Resin cement B
Metal cement M
Ceramic cement V
