Precision planar machining of metal materials commonly suffers from technical drawbacks including uneven unilateral stress, easy warpage of plates and large thickness dispersion. Conventional single-side lapping fails to satisfy the parallelism and flatness requirements of high-end metal foils, sealing parts and precision gaskets. Relying on core structural merits of synchronous grinding by upper and lower discs and simultaneous stock removal on double sides, the Double-Sided Metal Lapping Machine efficiently addresses machining challenges of easy deformation and excessive residual stress of metals, serving as core processing equipment for ultra-precision flattening of precision metal parts.

Different from single-side processing machinery, double-sided lapping adopts a planetary closed-loop motion structure. Both top and bottom surfaces of workpieces contact lapping discs synchronously with symmetrically distributed bilateral grinding force, fundamentally counteracting unilateral compressive stress generated in metal machining and drastically cutting reject rates caused by bending, twisting and warping of thin metal sheets. For diverse metals such as stainless steel, aluminum alloy, copper alloy and die steel, the machine enables uniform stock removal and prominently improves workpiece parallelism, flatness and thickness uniformity.

Under high-precision mass production conditions, metal workpieces impose stringent standards on dimensional tolerance, surface finish and batch consistency. Equipped with precise variable-frequency speed regulation, pressure-controlled feeding and disc leveling calibration systems, the Double-Sided Metal Lapping Machine delivers evenly distributed grinding paths and accurately controllable stock removal. It steadily eliminates tool marks, burrs, oxide layers and surface irregularities to achieve micron-level dimensional accuracy and uniform surface texture.

At present, the Double-Sided Metal Lapping Machine is widely deployed in finish machining of precision sealing rings, thin hardware sheets, hydraulic fittings and new-energy metal structural components. Featuring double-sided homogeneous grinding, low residual stress and outstanding dimensional consistency, it reduces rework and sorting costs, improves assembly precision and operational stability of finished products, and furnishes solid technical support for large-scale, high-quality mass production of precision metal components.
