Simec SPM 3000 Automatic Polishing Line
Polishing is where stone comes alive, and where it is least stable: uneven gloss across one batch is obvious the moment panels go on the wall. Hengsheng runs the Italian Simec SPM 3000 automatic line at 3,000㎡ per day, grinding through successive heads with pressure and speed regulated by servo loop per stone type, so an entire batch lands in one gloss band.
Core Strengths
- Continuous multi-head grinding: heads are arranged from coarse to fine so a slab completes every stage in a single pass, avoiding the gloss breaks that segmented processing creates.
- Servo-controlled gloss: each head runs to stone-specific parameters for pressure and speed, checked by gloss meter feedback, narrowing variation between batches.
- Large-format capability: slabs up to 3200×2000mm are handled, meeting lobby and curtain wall demand for large panels.
- Capacity behind the programme: 3,000㎡ a day, scheduled with the Foshan plant, underpins concentrated supply for large-area projects.
Key Figures
Service Process
- Loading: slabs dried and face-checked, with grinding parameters selected by stone type.
- Coarse grinding: saw marks removed and surface flatness unified.
- Progressive polishing: heads work coarse to fine, with pressure and speed held to parameters.
- Gloss measurement: sampled by gloss meter, with parameters corrected on deviation.
- Unloading: cleaned, dried, protected, then released to final inspection and packing.
Applications
- High-gloss floors and walls in hotel lobbies and commercial interiors
- Polished slabs for large-area curtain wall and ventilated facades
- Bespoke projects specifying honed, antique or other non-polished finishes
- Concentrated supply for programmes with tight delivery windows
Sustainability & Certification
Cooling water passes multi-stage settling and filtration before returning to the 95% plant recycling loop, with settled slurry collected for reuse.
Servo control reduces re-polishing caused by off-specification gloss, saving power and abrasive directly; variable-frequency drives cut standby consumption.
Deep Selection Guide
Polishing quality is not about how bright the stone is but whether a whole batch matches — a gloss difference of more than 5° between adjacent panels is visible to the eye. State the gloss requirement in the contract — 90° or above for polished work — together with the measurement method, and approve a sample before volume production. Honed and antique finishes should be sealed as reference samples for roughness too. For large-panel layouts, confirm the maximum slab size the line can handle so the design does not force joints the equipment cannot avoid.
- Selection criteria：High-gloss floors and walls in hotel lobbies and commercial interiors makes the most specific demands on the stone; satisfy it first, then use Continuous multi-head grinding to judge whether the process is feasible.
- Specification & thickness：Fix the base thickness by Polishing capacity (3,000㎡/day), then decide whether Polished slabs for large-area curtain wall and ventilated facades needs local adjustment; all cut-outs and junctions should be confirmed on the drawing first.
- Acceptance & records：Servo-controlled gloss must be checked and filed before dispatch and accepted on site by number; if a dispute arises later it can be traced to the batch data held.
- Sustainability：Cooling water passes multi-stage settling and filtration before returning to the 95% plant recycling loop, with settled slurry collected for reuse. State this specifically in the acceptance documents and keep it consistent with the environmental rules that apply.
Hengsheng holds Simec SPM 3000 Automatic Polishing Line together through full-chain management from quarry to site; linking selection, fabrication, QC and delivery is what surfaces risk before it turns into a problem.
FAQ
- Can gloss be kept consistent?
- Yes. The line regulates pressure and speed by stone type through a servo loop and checks by gloss meter feedback, holding the batch in one gloss band; polished work generally stays above 90°, confirmed on a sample first.
- What finishes are available besides polish?
- Honed, antique, bush-hammered, sandblasted and flamed finishes can be switched in, and leathered textures achieved with hand refinement; roughness and feel are confirmed against reference panels before production.
