Product Introduction
RSMT-200 Single Head Automatic Tombstone Polishing Machine
All-In-One Stone Surface Finishing Equipment With Auto Abrasive Changing
Monument processing factories usually need to manually swap multiple grinding abrasives for rough grinding, fine grinding and mirror polishing on tombstone slabs. Manual pad replacement wastes plenty of labor time and causes inconsistent gloss difference on finished products. This single-head integrated polisher comes with built-in automatic abrasive switching structure, which finishes full-gradient surface treatment from coarse grinding to high-gloss polishing in one unattended run, specially optimized for mass production of tombstones, memorial tablets and small decorative stone slabs.

Core Unique Advantages
1. Built-In Auto Abrasive Changing Structure, Zero Manual Intervention
The polishing head is equipped with a four-position abrasive storage turntable, preloaded with coarse, medium, fine and mirror polishing pads. After finishing one grinding stage, the machine automatically rotates to switch the corresponding abrasive without workers stopping production to disassemble and replace pads. It eliminates downtime caused by frequent manual replacement and realizes fully automatic unmanned polishing cycle.
2. High-Torque Spindle Ensures Uniform Gloss On Whole Slab
The 7.5kW high-power main spindle outputs stable downward pressure, cooperating with the 200mm large polishing disc. It quickly removes surface rough cutting traces and tool marks on granite tombstones, forming consistent mirror gloss across the entire workpiece. No local matte or uneven brightness defects that often appear with small handheld grinders.
3. Large Stroke & Extra-Long Worktable Adapt To All Standard Monuments
550mm vertical lifting stroke can process tombstone blanks of different thicknesses without repeated height adjustment. The 3500mm extended workbench supports ultra-long vertical memorial slabs, horizontal tombstone panels and engraved portrait stone in one-time clamping, avoiding secondary positioning errors caused by flipping heavy stone.
4. Reinforced Anti-Vibration Frame Guarantees Long-Term Precision
The whole machine adopts heavy-duty thick steel welded frame with total weight up to 5 tons. It effectively offsets high-frequency vibration generated during long-time polishing, preventing slab ripple marks and prolonging the service life of abrasives and spindle components. Matched circulating water supply continuously takes away grinding debris and heat, protecting polishing pads from premature burning damage.
5. Simple Touch Screen Operation Reduces Worker Skill Threshold
The independent mobile touch control cabinet stores multiple sets of pre-programmed polishing parameters for granite, marble and artificial stone. Operators only need to select the corresponding stone material to start automatic processing. Novice staff can independently operate the equipment without rich polishing experience.
Main Application Scenarios
✅ Mass production of granite and marble tombstones, memorial tablets and portrait carving slabs
✅ Surface finishing of landscape decorative stone, small architectural special-shaped stone
✅ Stone processing workshops focusing on customized monument export orders
✅ Small and medium stone factories upgrading from traditional manual polishing procedures
Factory Investment Benefits
- Labor cost reduction: Abrasive auto-switch frees workers from repeated pad replacement work, one operator can manage multiple machines simultaneously.
- Improve finished product yield: Automatic gradient polishing ensures uniform gloss, reducing rework caused by inconsistent manual grinding.
- Boost daily production capacity: Continuous unattended polishing shortens single-piece processing cycle and raises daily output.
- Wide material compatibility: Suitable for all conventional stone raw materials for monument manufacturing, flexible to switch between different order types.
