How to evaluate the polishing efficiency of a multi metallographic polishing machine?

The efficiency evaluation of the multi-metallographic polishing machine needs to be comprehensively considered from three aspects: single-piece processing time, multi-station coordination rate, and qualification rate:
Single-piece processing time:
Coarse polishing stage: When processing a 20mm×20mm steel sample, it takes 2-3 minutes to remove the cutting damage layer at 600 rpm and 2N pressure; Fine polishing stage: It takes 5-8 minutes to achieve a mirror effect at 400 rpm and 0.5N pressure; Total time: The processing time for a single sample is about 7-11 minutes, which is 40% shorter than that of single-station models; Multi-station coordination rate: Coordination rate = actual output volume; for example, if a 4-station model processes different materials at each station individually, the coordination rate can reach more than 90%; if processing different stages of the same material, the coordination rate is about 70-80%; Qualification rate: The qualification standard is that the surface has no scratches, orange peel, over-polishing, or other defects; because the parameters of multi-station models can be adjusted individually, the qualification rate is usually ≥95%; Efficiency optimization: By upgrading to a fully automatic model, the single-piece processing time can be further shortened to 5-7 minutes, and the coordination rate can be increased to over 95%.

The multi-metallographic polishing machines from Kunshan Fuze Testing Equipment Co., Ltd. are equipped with efficiency analysis software as standard, which can automatically record data such as processing time and qualification rate and generate efficiency reports.
