The JNLXM20 is designed for surface grinding and polishing of tombstones, architectural stone, and large-format slabs. The machine features a PLC digital control system and a modular body structure, ensuring stable operation, easy adjustment, and reliable production performance.
A high-rigidity four-column lifting structure, combined with linear guides and multiple sets of roller supports, ensures precise and smooth material conveyance. The conveying system replaces traditional sliding friction with rolling contact, reducing load, wear, vibration, and noise. The entire machine undergoes high-quality anti-corrosion treatment and is equipped with a pneumatic abrasive replacement mechanism, offering a wide range of processing capabilities; the entire production line is highly efficient, durable, and easy to maintain.
