RSPM-500 Single Head Bridge Automatic Polishing Machine

Flexible PLC-Controlled Stone Surface Finishing Equipment For Small-Batch Custom Orders

Multi-head continuous polishing lines focus on mass production of standard-size slabs, yet they lack flexibility for irregular stone, custom tombstones and small-volume special-shaped workpieces. This single-head bridge polisher adopts independent PLC programming control, freely adjusting grinding paths, pressure and speed to handle scattered customized orders that large polishing lines cannot accommodate. It is an essential auxiliary finishing machine for decoration stone factories, monument processing workshops and small stone fabricators.

Complete Technical Parameter Breakdown

Core Unique Product Advantages

1. PLC Independent Programming, Ultra-Flexible For Irregular Workpieces

Different from fixed-path multi-head polishing machines, this single-head model supports on-site manual programming. Operators can set arbitrary rectangular, arc, and partial polishing paths according to the outline of special-shaped countertops, curved tombstones and partial repair stone. It perfectly solves the processing pain point that large polishing lines cannot process scattered small-batch custom orders.

2. 15kW High-Torque Spindle Matched With Large 470mm Grinding Disc

The high-power main motor maintains stable downward pressure during grinding. The 470mm wide polishing disc covers a larger contact area, quickly eliminating surface tool marks, uneven textures and rough cutting lines on granite, marble and quartz stone. It effectively shortens the grinding cycle of thick hard stone and avoids local matte areas after finishing.

3. Full-Axis Large Travel Matches All Conventional Decorative Stone Sizes

3200mm horizontal Y-axis travel supports ultra-long vertical tombstone blanks, while the 2100mm front-back X-axis stroke fully covers standard slab widths. The 150mm vertical lifting stroke freely adapts stone thickness from thin wall tiles to thick monument raw blanks, eliminating repeated clamping and positioning errors caused by flipping heavy stone slabs.

4. Heavy Cast Integral Base Eliminates Polishing Vibration

The equipment adopts split yellow cast iron gantry base with strong overall rigidity. Even under continuous high-speed rotation of the polishing head, the machine body will not generate resonance vibration, preventing wavy ripple marks on the stone surface. The stable frame extends the service life of polishing abrasives and reduces spindle wear loss.

5. Simple Operation Logic Lowers Worker Skill Threshold

The physical control panel with intuitive button layout realizes one-click storage and recall of commonly used polishing programs. New staff can complete path programming and formal processing after half an hour of simple training, without relying on experienced polishing technicians to adjust complex equipment parameters.

Main Applicable Production Scenarios

✅ Custom monument processing: single-piece tombstone relief polishing, portrait slab surface finishing, irregular outline memorial stone

✅ Home decoration supporting processing: special-shaped kitchen countertops, curved window sills, stair treads, small vanity tops

✅ Small stone workshops with mixed scattered orders, unable to deploy large multi-head polishing lines

✅ After-finishing repair procedures for slabs with partial unqualified gloss from continuous polishing lines

✅ Landscape stone and small art craft stone surface mirror finishing

Long-Term Economic Value For Stone Processing Factories

1. Expand business coverage: Take on small customized special-shaped orders rejected by large polishing lines, creating new profit sources for factories.
2. Cut auxiliary labor cost: Replace manual handheld grinders for large-area polishing, reducing worker fatigue and the number of front-line finishing staff.
3. Improve finished product yield: Stable mechanical grinding pressure ensures uniform full-slab gloss, lowering rework loss caused by inconsistent manual polishing brightness.
4. Flexible production coordination: Cooperate with bridge cutting machines and engraving equipment to form a complete small-batch customized processing production line.
