Pre-grinding Micro Vickers Hardness Tester YS7118 0.2KW 380V 50Hz

Pre-grinding Micro Vickers Hardness Tester YS7118 0.2KW 380V 50Hz

Description:

The pre-grinding of the specimen is an indispensable process before its polishing in the preparation of the specimen.The pre-grinding enhances greatly the efficiency of the specimen praparetion.YM-1 Pre-grinder is the result of a large-scale research work and the wisdom of the designers as well as the suggestions of the users.As an excellent piece of specimen pre-grinding,the pre-grinder has a lap with a larger diameter compared with the same kind of machines produced in our country and the rotational speed of its lap is quite different form that of the machines turned out in our country in order to meet the requirements of the pre-grinding of various materials. 　　
The working principle of YM-1 Pre-grinder is as follows:clear water provided by a water tube flows into the rotating lap and the abrasive paper flowing over the water throws the water out of the lap as the result of the excentric force of the ratating lap forming a vacuum space before the atmospheric ressure presses the abrasive paper on the lap tightly.Now it is time to operate the pre-grinding.When the lap stops rotating,the work is done and abrasive paper can be easily taken off.

The Electric Motor:YS7118,0.2KW,380V,50Hz
Total Dimension:460*340*330mm
The Rotational Speed:700r/min
The Net weight:22kg

Name:YM-2A

Description:

During Metallurgical Sample preparation, pre-grinding is a necessary prevenient work of polishing.Pre-grinding the samples can greatly improve preparation efficiency.YM-2A was designed after collecting many customers' suggestions and requests.To adjust to all kinds of material pre-grinding, the grinding wheel size of YM-2A is larger than the same products in China.The rotating speed is different from other products.YM-2A is the best choice for Metallurgical sample pre-grinding. 　　
Working Principle of YM-2A: Through pipe,water flow to the rotating grinding wheel. The eccentrical force throws the water under grinding disc,and forms vacuum which attracts it to do pre-grinding work.Stop rotating, the eccentrical force loses and the grinding disc can be taken off.
