Problems solved by technology

[0002] At present, in the field of artificial graphite production, in order to test various performance indicators of graphite materials, it is necessary to make graphite samples and polish the surface; especially for ultra-thin graphite samples with a thickness of 0.5-2mm, polishing has become the most critical step. The traditional processing method is to slowly and intermittently polish and polish it through the grinding method, that is, when polishing and grinding, the graphite sample rises steadily and then stops grinding, and waits for and automatically cools down before grinding again. Poor time to wait, resulting in low production speed of ultra-thin graphite samples, and graphite samples are easily deformed and curled during the grinding process, which makes its quality difficult to control

Abstract

The invention relates to the technical field of graphite sample machining, in particular to a machining method of an ultra-thin graphite sample. The machining method comprises the following steps of feeding, surface A grinding, reversing and surface B grinding and comprises the following specific steps that a blank is fixed on a positioning part B, then the graphite sample is driven to be in contact with a wheel, grinding is carried out on the surface A of the graphite sample, then upper and lower reversing is carried out on the graphite sample, and then the graphite sample is fixed on a positioning part A; then grinding feeding is carried out on the graphite sample, and then grinding is carried out on the surface B of the graphite sample; and repeated circulation grinding is carried out to obtain a finished product. According to the machining method, single reciprocating grinding is correspondingly carried out on the upper surface and the lower surface of the graphite sample in a circulating reversing manner of the upper surface and the lower surface, moreover, dust blowing is carried out on the grinding surfaces after single grinding by using positive pressure airflow, and cooling treatment is carried out in a negative pressure adsorption mode in the grinding process, so that the overall temperature and the grinding quality of the graphite sample in the grinding process can be controlled, and the technical problem that the machining quality of an ultra-thin graphite sample is difficult to control in the prior art are solved.
