Description

A kind of SEM grind away sand paper

Technical field

The utility model relates to a kind of SEM grind away sand paper.

Background technology

Sand paper is commonly called as rubber, is a kind of for abradant material, in order to the surface such as abrasive metal, timber, to make it smoothly bright and clean.

SEM is widely used in the observation of microstructure, when observing sample, has many samples to need to carry out polishing.Existing sample grinding machine needs when preparing sample to carry out physics polishing with special sand paper.

In prior art, the step of physics polishing is as follows: first roughly grind with roughness larger sand paper (normally mark 200 " person 300 "), after being placed on basis of microscopic observation surfacing, changed by the sand paper of this roughness; And then polish with the sand paper (usual mark is 600 " or 800 ") of intermediate roughness, through this step polishing after, sample is put grind away under the microscope roughly smooth after change sand paper; Finally sample is put into the less sand papering of roughness (be masked as 1200 ") sand paper on polished after, after putting under the microscope completely polishing, sample just calculate prepare intact.

In above-mentioned grind away process, when sample grinding machine rotating speed is certain, the closer center, position at edge has larger linear velocity, because sample is more fragile, so in roughing operations, sample generally grinds by paracentral position at grind away platform, so in roughing operations, sand paper marginal position utilization rate is very low.And when refining, in order to comparatively fast prepare sample, usually sample is placed on the position grinding at edge, so in fine grinding operation, the central part utilization rate of sand paper is very low.

Therefore, loaded down with trivial details for above-mentioned physics polishing process, the problems such as consuming time longer, operating efficiency is lower, and sand paper utilization rate is low, are necessary to develop a kind of novel SEM grind away sand paper, to increase work efficiency and the utilization rate of sand paper.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of SEM grind away sand paper, solves low, the ineffective problem of sand paper utilization rate in prior art.

To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of SEM grind away sand paper, comprises body paper, described body paper is provided with from inside to outside successively the first milling zone, the second milling zone and the 3rd milling zone;

In technique scheme, the order number of described first milling zone is 100 ~ 400, and the order number of described second milling zone is 500 ~ 900, and the order number of described 3rd milling zone is 1000 ~ 1200.

Preferably, the order number of described first milling zone is 300; The order number of described second milling zone is 700; The order number of described 3rd milling zone is 1100.

Preferably, transition region is provided with between each neighboring abrasive district.

In further technical scheme, described transition region is annular, and its width is 3 ~ 10mm.

Corresponding another kind of technical scheme, a kind of SEM grind away sand paper, comprises body paper, described body paper is provided with from inside to outside successively the first milling zone, the second milling zone and the 3rd milling zone;

Described first milling zone, the second milling zone and the 3rd milling zone are annular, and described three milling zones form concentric structure;

Because technique scheme is used, the utility model compared with prior art has following advantages:

1. the utility model is provided with multiple milling zone, and the order number of milling zone is different, different milling zone can be selected to grind, avoid and repeatedly change sand paper, effectively improve the utilization rate of sand paper, improve operating efficiency, reduce material cost when grinding;

2. the utility model structure is simple, and it is convenient to implement, and is beneficial to popularization.
