The CX20-45 type 9‑head pneumatic polishing machine is a fully automatic, high‑precision polishing device specially designed for PC imitation stone curbstones, paving stones, large slabs, and landscape stones. It integrates flat surface polishing, side surface polishing, and edge/chamfer polishing functions into one unit, perfectly matching the subsequent fine‑processing steps of high‑pressure molded PC stone products. It effectively addresses longstanding industry pain points such as uneven polishing, rough edges, significant surface color variations, and poor texture, making it a core precision finishing accessory for high‑end imitation stone slab production lines.

The equipment adopts an industry‑leading pneumatic polishing assembly structure, featuring independent pneumatic flexible polishing designs for the front and sides. The polishing heads automatically adapt to the curvature and flatness of the stone surface, achieving precise contact between the abrasive material and the stone surface for uniform pressure distribution, eliminating missed areas or over‑polishing. The finished slabs exhibit a delicate, translucent finish with consistent gloss, while edges and corners are smoothly rounded and neatly shaped, faithfully reproducing the premium texture of natural granite and marble, significantly elevating product grade and market premium potential.

The machine offers broad compatibility with various stone product specifications, accommodating minimum processing dimensions of width 150 mm and height 100 mm, up to maximum dimensions of width 450 mm and height 200 mm, comprehensively covering mainstream product sizes such as standard curbstones, municipal paving stones, and small imitation stone slabs. One machine can meet diverse polishing needs across multiple product categories, boasting strong versatility and suitability for large‑scale assembly line operations. The overall external dimensions are 8160 × 1600 × 1908 mm, with a well‑planned layout that occupies a compact footprint, seamlessly integrating with upstream molding and downstream curing production lines to enable fully automated end‑to‑end manufacturing.

The machine’s total power reaches 37.32 kW, delivering ample energy and stable output to support high‑intensity, high‑frequency continuous polishing operations. All core components are sourced from top‑tier brands, ensuring solid quality and durability: equipped with a Shanghai Lichao motor, offering robust power, stable operation, and low failure rates; paired with a Shanghai Shuangzhao reducer, providing precise transmission, sufficient torque, and exceptional wear resistance; the control system incorporates Delta inverters and Delta PLCs, featuring mature programming logic and precise regulation, enabling intelligent adjustment of polishing speed and grinding intensity for smooth, accurate performance; other electrical components are supplied by Chint, ensuring safety, stability, and convenient after-sales service, greatly reducing equipment failure rates and maintenance costs.

Compared with traditional mechanical hard‑grinding polishing equipment, this machine’s pneumatic flexible polishing offers distinct advantages, automatically fine‑tuning polishing gaps to effectively prevent issues like uneven grinding, chipping, or scratches caused by minor dimensional deviations in the slabs, resulting in an exceptionally high yield of qualified products. With its high degree of automation and fully intelligent programmed operation, the machine requires no manual intervention, substantially cutting labor costs and boosting polishing efficiency, making it ideal for factory settings operating around the clock. After polishing with this machine, PC stone surfaces exhibit superior smoothness, natural textures, and enhanced weather resistance, free of burrs or defects, ready for direct application in high‑end scenarios such as municipal roads, garden landscapes, upscale residential complexes, and commercial projects.

The CX20-45 type 9‑head pneumatic polishing machine features high‑end configuration, advanced processes, and comprehensive functionality, integrating flat surface, side surface, and chamfer polishing into one unit. Thanks to its pneumatic flexible precision polishing technology, stable branded component configuration, and broad processing compatibility, it has become the preferred choice for fine‑processing PC imitation stone products, helping enterprises create high‑quality imitation stone offerings and strengthen their core competitiveness.
