Yuhuan YH2M8436A

YH2M8436A is a double-side grinding/polishing model for metal plates/rings and hard brittle sheets. Its exact English table states 360 mm as the maximum rectangular diagonal and 0.4 mm as minimum machined thickness. The listed upper/lower disc size is Ø1148 × Ø355 × 45/50 mm; confirm the thickness alternative and carrier pocket drawing rather than equating disc diameter with usable workpiece size.

The source describes independent drives for the upper disc, lower disc, sun gear and inner ring, closed-loop sensor feedback, pressure compensation, temperature-controlled coolant and three-stage filtration. The carrier reference is DP12, 200 teeth, with 3–5 planet wheels. Listed speeds are lower disc 10–60 rpm, upper disc 3–16 rpm, sun gear and ring gear each 3–30 rpm. Qualify the actual recipe, carrier occupancy and abrasive for the material and removal requirement.

The table’s 0.006 mm “precision” has no defined geometric metric; 0.01 mm thickness dimensional accuracy and its grinding/polishing roughness statements also require process and inspection conditions. Specify thickness locations, flatness, parallelism, roughness and damage limits separately, then inspect a cleaned representative lot after release. Published size/mass are approximately 2050 × 1500 × 2700 mm and 4500 kg; confirm installation, access, utilities, supplied safety functions and service scope.
