The HLMJX-16W Automatic Continuous Stone Polishing Machine is a robust, multi-head stone polisher meticulously developed for the relentless honing and polishing of natural and engineered stone slabs. With its astounding 16 independent polishing heads, this automatic machine ensures the production of flawless, mirror-like finishes on marble, granite, quartz, and composite materials while providing phenomenal throughput. PLC-controlled operation, assisted by a user-friendly LCD menu, enables operators to refine grinding head pressure and processing width to exactly fit a broad selection of slab profiles.


An integrated optical slab scanner in the infeed measures each slab's contour and sends the CNC controller shape information in real time for edge-to-edge perfection polishing. A central automatic lubrication system keeps all bearings and moving components well lubricated, minimizing service life and downtime. Thanks to its chip-removal system and self-cleaning conveyor, the HLMJX-16W ensures excellent surface quality while ensuring smooth operations in the stone workshop.

Marble Slab Polishing: Achieve high‑gloss finishes and even surfaces for countertops and decorative wall panels.
Quartz and granite finishing creates a consistent sheen on the big slabs utilized in bathrooms, kitchens, and business floors.
Engineered Stone Processing: Polish sintered and composite slabs under controlled pressure to reveal consistent patterns.
Mass production is ideally suited for batch runs in fabrication plants that require constant throughput and low handling.
Profile Honing: Polish and finish the cut edges to create custom profiles, bullnose, ogee, and bevel finishes.
Pre-installation preparation entails the final surface preparation of cladding panels, stair treads, and niche surrounds.



High-Capacity Throughput: Sixteen polishing heads that work together simultaneously offer continuous operation—ideal for high-volume stone production.
Adaptive Pressure Control: Operator‑adjustable head pressure provides consistent results with different material hardness.
Accuracy contour scanning uses entrance sensors that provide real-time geometric data, allowing edge-to-edge polishing accuracy.
Automatic Lubrication: Centralised oiling system extends component life and reduces maintenance downtime.
Effective Debris Management: Self-cleaning conveyor belt and in-built chip extractor provide a clean and safe working environment.
User‑Friendly Interface: PLC control with LCD menu simplifies recipe development and process changes on the fly.
Multi-Function Material Compatibility: It is able to polish marble, granite, quartz, engineered stone, and certain ceramics.
Energy‑Efficient Operation: Optimized drive motors and servo controls to minimize power consumption per slab.
Space‑Saving Footprint: Combines multiple steps of polishing in one machine, reducing shop floor space. Outfitting your shop with the HLMJX-16W will consolidate stone finishing procedures, reduce productivity time, and ensure every slab produces a showroom-quality surface finish.
