Abstract
The utility model relates to a from inhaling formula mill for metallographic specimen pre-grinding machine belongs to metal material surface and polishes technical field. The grinding disc comprises a grinding disc body, wherein a plurality of through holes are formed in the surface of the grinding disc body and distributed around the center of the grinding disc body at intervals in an annular mode, and the minimum distance between the outer edge of each through hole and the edge of the grinding disc body is larger than or equal to 8 mm. The number of the through holes is 12-18. The center line of the through hole is vertical to the surface of the grinding disc body or forms a certain angle with the surface of the grinding disc body. This application sets up a plurality of through-holes on the mill body, and the water warp through-hole flows, because inertial action for the absorption that water sand paper can be firmly has avoided the phenomenon that water sand paper upwarped on the mill body, and water also can not splash out, has both purified operational environment, has improved the comfort level and the efficiency of grinding appearance moreover, has guaranteed operating personnel's personal safety.
Description
Technical Field
The utility model relates to a from inhaling formula mill for metallographic specimen pre-grinding machine belongs to metal material surface and polishes technical field.
Background
The preparation of the metallographic specimen is an essential important step in the whole metallographic test process, the quality of the specimen preparation directly influences the test result, and the speed and efficiency of the specimen preparation, the environment in the specimen preparation process, the comfort and safety of an operator in the specimen preparation process and the like are very important.
The common sample preparation steps of the prior metallographic sample are as follows: grinding wheel rough grinding, rough grinding of coarse sand paper, pre-grinding of 180-mesh water sand paper, pre-grinding of 600-mesh water sand paper, pre-grinding of 1200-mesh water sand paper and polishing. The three pre-grinding steps are all completed on a metallographic specimen pre-grinding machine, a piece of waterproof abrasive paper is placed on a grinding disc of the metallographic specimen pre-grinding machine, the metallographic specimen pre-grinding machine is started, then a sample is held by hand to be ground on the waterproof abrasive paper, and the sample is held by hand to be ground on the waterproof abrasive paper in the environment with running water flowing in the pre-grinding process. In the grinding process, the edge of the waterproof abrasive paper is continuously tilted, the edge of the waterproof abrasive paper which is continuously tilted can not only scratch the arm of an operator easily, but also cause other damages caused by the flying-out of a sample, influence the grinding operation of the sample and reduce the sample grinding efficiency; in addition, the edge of the waterproof abrasive paper is raised during the grinding process, so that water can be splashed outwards, and the waterproof abrasive paper not only can pollute and wet operators, but also can pollute the surrounding working environment.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a provide a from inhaling formula mill for metallographic specimen pre-grinding machine to above-mentioned prior art, eliminate the phenomenon that metallographic specimen was perk at the edge of grinding in-process water sand paper, guarantee operation safety, operational environment cleanness, grind appearance efficiently grinding at the appearance in-process of grinding.
The utility model provides a technical scheme that above-mentioned problem adopted does: the utility model provides a from inhaling formula mill for metallographic specimen pre-grinding machine, includes the mill body, a plurality of through-hole around mill body center ring interval distribution is seted up on the mill body surface, distance more than or equal to 8mm between through-hole outside edge and the mill body edge.
The number of the through holes is 12-18.
The through hole is a straight hole with a central line vertical to the surface of the grinding disc body, or an inclined hole with a central line inclined relative to the surface of the grinding disc body.
Compared with the prior art, the utility model has the advantages of: the utility model provides a from inhaling formula mill of inhaling for metallographic specimen pre-grinding machine sets up a plurality of through-holes on the mill body, and water flows through the through-hole, because inertial action for the absorption that water sand paper can be firmly on the mill body has avoided the phenomenon that water sand paper upwarps, and water also can not splash out, has both purified operational environment, has improved the comfort level and the efficiency of grinding the appearance moreover, has guaranteed operating personnel's personal safety.
Drawings
Fig. 1 is a schematic diagram of a self-suction type grinding disc for a metallographic specimen pre-grinding machine according to an embodiment of the present invention;
FIG. 2 is a schematic reverse side view of a self-priming grinding disc for a metallographic specimen pre-grinding machine according to an embodiment of the present invention;
in the figure, 1 grinding disc body and 2 through holes are arranged.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the self-suction grinding disc for the metallographic specimen pre-grinding machine in the embodiment includes a grinding disc body 1, 16 through holes 2 are formed in the surface of the grinding disc body 1 and annularly distributed around the center of the grinding disc body 1 at intervals, and the distance between the outer edge of each through hole 2 and the edge of the grinding disc body 1 is 9 mm. Through-hole 2's central line is perpendicular and 1 surface of mill body, when grinding metallographic specimen, the running water of pouring can be quick flow out from through-hole 2, because rivers inertia effect for absorption that water sand paper on the mill body 1 can be firmly on mill body 1, has avoided the phenomenon that water sand paper upwarp, and water can not splash everywhere, has both purified operational environment, can not fish tail operation personnel's arm again, has improved the comfort level and the efficiency of grinding the appearance.
Of course, the center line of the through hole 2 can also be designed to be inclined with the surface of the grinding disc body 1, and the grinding disc body 1 can realize the self-absorption function.
In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
