Background technology
Metallographic pre-mill is a kind of wet grinder, it utilizes various varigrained water resistant sand paper, to various metals and
The sample of its alloy is polished.Raising hand-manipulated is replaced to prepare sample efficiency using metallographic pre-mill divided by mechanical polishing
In addition, moreover it is possible to the plastic deformation generated in sample cutting process and surface heating traces are removed completely, it is laggard further to polish
The micro- measurement of row tissue.Metallographic pre-mill work when, clear water is constantly injected on the mill of rotation, the water below water resistant sand paper because
The effect of centrifugal force is spilled over outside disk, and sand paper can freely stretch under atmospheric pressure to be tightly attached on mill, because
And by sand paper bonding or need not clamp, it uses and replaces and is very convenient.
Metallographic pre-mill clamps utensil when being polished to sample, without dedicated sample, is only capable of trying by human hand held
The shortcomings that sample is polished sample on mill, and hand-held sample is polished be：1. since sample is in polishing process, hold
It is easily firmly uneven when sample, it causes the grinding and polishing face of sample that cannot be tightly attached to completely on the water resistant sand paper in mill, causes water resistant
Sand paper grinds multiple grinding and polishing faces in irregular shape, final to influence group inside sample to prevent sample from reaching test requirements document
The micro- measurement knitted；2. water resistant sand paper, since mill is rotated with higher speed, is being ground during being polished to experiment
There is larger centrifugal force, hand-held sample to be easy to cause sample and are thrown out of under the action of larger centrifugal force during disc spins
To make sample be detached from mill, while causing a hidden trouble to personal safety.
