130mm 扁平超細研磨機 附球墨鑄鐵框架

The 4:1 gear ratio makes cranking through thicker metal feel effortless, and I was genuinely surprised I could get foil down to 0.001" consistently. The 130mm flat area held its tolerance perfectly after several uses.

I was skeptical about getting foil that thin, but the .001" capability is real and consistent across the full 130mm width. The 4:1 reduction makes it easy to get uniform thickness without fighting the rollers.

The gear ratio is perfect for my needs—it reduces effort noticeably without sacrificing control. I was able to roll out a consistent 0.1mm sheet on the first try, and the flat area stays true to the claimed +/-0.01mm tolerance.
