YH2M8419 is the double-side grinding/lapping model on Yuhuan’s exact English page for thin metal parts and hard brittle sheets. Both grinding discs are listed as Ø640 × Ø235 × 35 mm. The table’s 190 mm maximum part size has no stated measurement direction; the 0.2 mm minimum-size row is also ambiguous. Ask for a carrier drawing and an explicit minimum thickness instead of treating either figure as a universal geometric limit.
The page describes planetary motion, disc correction/dressing, pressure detection with proportional adjustment, PLC/touchscreen operation and an upper-disc safety lock. Its Ø315 mm, 108-tooth, DP12 row appears under an unclear translated label. Confirm the actual carrier and motion arrangement together with loading occupancy, abrasive, removal allowance and coolant for the submitted part.
The published flatness/parallelism within 0.003 mm is associated with a Ø65 workpiece. Define material, process, sampling and released-part measurement conditions before using it for another size. The lower disc is listed at 0–65 rpm and the machine at approximately 1551 × 1300 × 2450 mm and 2000 kg. A sample-lot trial should include dressing, loading, cleaning, geometry and edge-damage inspection; these are not guaranteed output figures.
