Description
Technical field
A kind of machinery processing apparatus, more particularly to a kind of metallographic sample Grinding and polishing machine are the utility model is related to, is further related to
A kind of clamp base for the metallographic sample Grinding and polishing machine.
Background technology
Metallography originating from 19th-century mid-term, rapid promotion and application are obtained once coming out, have become steel
The important detection means of industry, over more than 100 years, under the effort and exploration of countless elder generation, Metallographic Techniques constantly develop.Such as
Modern Metallographic Techniques illustrate its huge glamour in fields such as research and development of new product, quality control and failure analyses.GPRS metallographic
Technology, the metallographic sample of high quality just can be prepared first.
The preparation of high quality metallographic sample, generally require to undergo following link：Polishing, polishing, corrosion.And wherein,
Difficulty highest, the link for being also most difficult to control are polishing and polishing.
At present, the method for polishing typically has two kinds：One is polishing by hand, and hand-held sample is being lined with the sand paper left-hand seat of glass plate
Dynamic polishing；Two be that mechanical polishing machine polishes, and hand-held sample is placed on sanding machine and sample is polished using the rotation of sand paper.This
Problems with often occurs during kind polishing：
1）Cut：The principle of polishing is that the sharp tip of tempering exposed on sand paper is cut sample, and polishing uses
Sand paper, once rust, shear action reduces abrasive particle, while also has a small amount of abrasive particle and come off from sand paper, the abrasive particle to come off with
Rolling occurs for sample surfaces so as to cause superficial layer to be deformed metal level or cut.Metallographic sample polishing process include corase grind,
Fine grinding.The required sand paper grain size number used is respectively 400,600,800,1000, and its cutting speed is sequentially reduced, scratch depth according to
Secondary reduction.In polishing process, polished since low sand paper, be milled to cut direction and unanimously change height sand paper afterwards, together with upper
Grind the direction vestige in 90 ° for grinding off upper track sand paper and leaving.Easily occurs problems with the process：Such as from 400# sand
Paper is changed to after 600# sand paper, and due to the artificial error of observation, the cut for takeing for having left 400# sand paper is ground off completely, real
But there is the cut that a small amount of 400# sand paper leaves on border；When being polished in replacing to 800# sand paper, grinding direction and 600# sand
Paper grinding direction is in 90 °, parallel with 400# sand paper grinding direction.At this moment it can find that the cut that 400# sand paper leaves is difficult to grind off,
And it is not easy to judge that these cuts are scratched as caused by 400# sand paper or by mass defect of 800# sand paper itself or Grain Falling Off
, thus inconvenience is correctly handled.
2）Come off：When grinding has the sample of precipitate or non-metallic inclusion, due to precipitate or non-metallic inclusion
The plastic deformation ability different from matrix, if milling time is grown in sample making course, grind firmly uneven or conference of exerting oneself
Precipitate is caused to deviate from from sample surfaces and leave hole.
3）Additional facet：In manual polishing procedure, it is difficult to ensure that arm long-time held stationary, occurs level side unavoidably
Upwards due to exert oneself it is uneven caused by additional facet occur.
At present, polishing is carried out on special polishing machine.Polishing machine is mainly by motor and sand disk(-sc)（Ф200-
300mm）Composition, polishing disk rotating speed is more than 200-600r/min.Polishing disk upper berth is with fine canvas, woollen goods, silk etc..During polishing
The continuous instillation polishing agent on polishing disk.Polishing agent generally use Al2O3, MgO or Cr2O3Deng fine powder（Granularity is about 0.3-1 μ
m）Suspension in water.Mechanical polishing is exactly to lean on the relative grinding of generation and hydraulic action between superfine polishing powder and flour milling
Eliminate polishing scratch.Sample flour milling is equably pressed on the polishing disk of rotation during operation, and constantly made along the edge of disk to center
Diametrically reciprocate.Polishing time is generally 3-5min.Sample after polishing, its flour milling should be bright seamless, and graphite or are mingled with
Thing etc. does not answer jettisoning or has conditions of streaking.Easily there is problems with this polishing process：
1）Hangover：Hangover often occurs having around softer phase or non-metallic inclusion.In polishing, polishing cloth is too dry,
Surface does not moisten, or sample is mobile inadequate in situ, abrasive material plug collection is thrown out of afterwards to a certain extent, in sample at hole
Surface is left a trace, and produces hangover.
2）Cut：If polishing fabric is unclean or abrasive material is not kept strictly completely and is mixed into dust, burnishing surface meeting
There is cut.Cut can influence observation and be polished, it is necessary to return on sand paper when serious, then polish again.
3）Etch pit：When operator skillfully grasps polishing-polishing skill, whole polishing-polishing process can be on 5 minutes left sides
Right completion.If the overly wet profit of polishing fabric, polishing time are again long, small micro cell is often formed above burnishing surface, so as to make
Into etch pit, pit is commonly called as.
Drawbacks described above in the metallographic sample polishing polishing process of prior art has had a strong impact on metallographic sample polishing polishing
Efficiency and quality.
And in phasor measure, multiple phases in alloy sample often be present, the hardness of each phase differs, and some samples
It is crisp and loose, materially increase the difficulty of polishing polishing process.It is determined by experiment, a ternary phase diagrams section is past
Toward more than 50 samples of needs, complicated system may need more samples.Therefore, polishing polishing efficiency and its quality are improved
It is extremely important.
