Hualong Machinery HLS-14S Automatic granite edge polishing machine is equipped with 14 grinding heads. It is a professional all-in-one equipment for stone processing factories to perform contour grinding, chamfering, edge trimming and polishing on marble and granite slabs.
This machine supports processing of French edge, circular arc edge, straight edge, 44.5° bevel edge and various special-shaped edges. Rough grinding, fine grinding and polishing can be completed in one single process. The glossiness of the processed stone edge is highly consistent with the brightness of the slab surface.
Hualong Machinery HLS‑14S Automatic granite edge polishing machine is optional with snail clips and quick connectors, compatible with 150 mm resin grinding wheels. The feeding speed is continuously adjustable, greatly replacing manual grinding. The production capacity of one single machine equals that of 15 skilled workers. It completely eliminates manual‑processing defects such as chipped edges, uneven brightness and inconsistent contours caused by hand‑operated work. It is widely applied in mass production of kitchen‑bath countertops, window sills, stair treads and skirting boards.
Equipment Features
1. Integrated design with 14 grinding heads for one‑step forming: Multiple grinding heads perform shaping, rough grinding, fine grinding and polishing respectively. Finished products are obtained after one pass of slabs without secondary handling.
2. Compatibility with diverse profiles: Capable of processing dozens of stone profiles including straight edges, bevel edges, French edges, circular arcs and skirting‑board profiles. Processing styles can be quickly switched by changing molds.
3. Stable gloss performance: Adopts automatic wet‑type polishing. The edge gloss is close to that of the slab surface for consistent product quality, ideal for large‑volume export orders.
4. Optional quick connectors: Compatible with 150 mm resin grinding wheels. Snail clips enable fast mounting and dismounting of grinding wheels to save time and labor during wheel replacement.
5. Variable‑frequency feeding speed: Conveyor speed ranges from 0.5‑4.5 m/min. The feed rate can be flexibly adjusted according to stone hardness and processing complexity.
6. Robust machine frame: Heavy‑duty welded frame with a total machine weight of 4500 kg. Low vibration during high‑speed operation ensures stable processing accuracy for long‑term production.
7. User‑friendly electric control console: Centralized control panel with visualized parameters. Even new operators can get started quickly, lowering technical requirements for workers.
8. Wide processing specification range: Minimum workpiece size 50×50 mm, slab processing thickness 3‑80 mm. It covers processing demands for various stone materials from thin to thick slabs.
Optional Configuration
1. Snail clips + Quick connectors (compatible with 150 mm resin grinding wheels)
2. Multiple sets of forming grinding wheel assemblies for different profile shapes
3. Cooling water circulation system
4. Full‑machine protective enclosure
