Manual Radial Arm Stone Polishing Machine
High-efficiency, flexible surface finishing & edge polishing solution for granite, marble, and engineered stone.
Product Overview & Equipment Positioning
The Manual Radial Arm Stone Polishing Machine (Model SFM-2600A/B Series), manufactured by Fujian Province Kaida Stone Machinery Co., Ltd., is an industrial-grade, highly flexible surface finishing solution engineered specifically for stone processing plants, tombstone/monument workshops, and custom architectural slab fabricators.
Equipped with a 360-degree double-articulated swivel radial arm with a maximum rotation radius of 2,600 mm, the machine delivers expansive coverage over large granite and marble slabs. By utilizing a heavy-duty solid round column (cylinder) as its vertical guide slip surface, the SFM-2600A/B guarantees exceptionally smooth, vibration-free automatic and manual vertical movements.
Unlike fully automated line polishers that require lengthy setup times and rigid slab dimensions, this manual radial arm polisher offers unmatched versatility for short-run processing, custom edge profiles, surface defect repair, tombstone face grinding, mosaic polishing, and arc slab finishing (when paired with an optional rotating table).

Key Mechanical Features & Structural Design
1. Heavy-Duty HT200 Cast Iron Structural Frame
The core body and base column of the machine are cast from HT200 high-strength grey cast iron. The high density and thermal stability of HT200 cast iron effectively absorb mechanical vibrations during heavy stock removal, preventing tool chatter, surface unevenness, and swirl marks on delicate marble or brittle granite slabs.
2. Precision Round Column Cylinder Guide Surface
The vertical lifting system features a precision-machined solid round column (cylinder) as its guide slip surface. This design maintains strict coaxial alignment and rigidity during up-and-down adjustments, ensuring that down-pressure remains uniformly distributed across the entire workpiece surface.
3. High-Torque SIEMENS Main Drive Motor
Driven by an industrial-grade SIEMENS main motor mounted on a heavy-duty reinforced seat base, the machine offers two drive configurations:
- Single-Speed Drive (5.5 kW): Constant speed optimized for standardized polishing routines.
- Dual-Speed Drive (7.5 kW): Low speed delivers high torque for aggressive coarse diamond grinding and calibration; high speed provides smooth velocity for fine resin buffing and high-gloss mirror finishing.
4. Advanced PANASONIC PLC & Touch-Sensitive Panel
The control architecture integrates a PANASONIC PLC and frequency converter (inverter), paired with an ergonomic touch-sensitive control panel. Workers can easily set vertical travel parameters, adjust spindle speeds, and control wet feed lines without manual effort.
