Details of Used 9B Double-Sided Polishing Machine/Grinding Machine

 I. Basic Parameters Model and Condition Model: 9B, approximately 80-90% new. Transmission Method: Mechanical transmission, main motor power 380kW. Processing Accuracy: High precision (0.001mm level). Dimensions and Weight Overall Dimensions: 1000×1200×1900mm (Heriot model), or 2200×2700×1100mm (different configurations). Equipment Weight: 1700kg to 3200kg (other models). Grinding Disc and Processing Range Grinding Disc Material: QT450 cast iron (upper and lower discs). Maximum Processing Diameter: 220mm, some configurations support workpieces up to φ400mm.

 II. Core Structure and Materials Main Transmission System Uses enclosed gearbox transmission, with four independent frequency conversion speed regulation motors (upper disc, lower disc, internal gear ring, sun gear). The internal gear ring is driven up and down by hydraulic cylinders, capable of free stopping and self-locking. Upper and Lower Disc Systems The upper disc features a gantry structure with strong support rigidity; the beam can open 120° for easy maintenance. Employs a single cylinder design, supporting fast rise/fall, slow rise/fall, and precise unloading functions. Key Component Materials Gear Ring/Sun Gear: 410 stainless steel. Transmission Gears: 40Cr alloy steel; Bushings: GCr15 bearing steel. 

III. Application Scenarios and Functions Suitable Materials Silicon wafers, quartz, sapphire, ceramics, optical glass, metals (such as aluminum alloy, stainless steel), etc. From small workpieces (e.g., valve plates, sealing rings) to large precision components (e.g., sapphire substrates). Process Characteristics Supports double-sided grinding/polishing, achieving precise control by adjusting parameters such as speed, pressure, and time. Can be configured with polishing slurry (containing abrasive particles and chemical additives) to improve surface finish.
