1. Product Overview & Market Positioning
The Vertical Edge Polishing Machine (Model: XTJ-200) manufactured by KAIDA STONE MACHINERY is an industrial-grade, continuous-pass edge grinding and profiling solution engineered for medium-to-large-scale stone fabricators, countertop manufacturers, and architectural cladding processors.
Designed specifically to eliminate the labor-intensive bottleneck of manual edge processing, the XTJ-200 integrates rough profiling, chamfering, fine grinding, and high-gloss polishing into a single automated line. Operating on a heavy-duty vertical conveyor structure, the machine handles stone thicknesses from 10 mm up to 60 mm, providing commercial stone processing factories with consistent edge geometry and standardized surface polish.

3. Working Principle & Operational Process
The XTJ-200 operates on a synchronized continuous linear feed system:
|
1. Slab Transport & Clamping Slabs are held vertically against non-marking support rollers and conveyed across the processing bed by a heavy-duty rubber belt.
2. Primary Profiling (Station 1–3) Three Ø200 mm diamond shaping heads perform fast stock removal to establish straight edges, chamfers, or specified profiles.
3. Sequential Polishing (Station 4–8) Five Ø200 mm polishing heads progressively refine the scratch pattern using grit-calibrated polishing discs.
4. Automatic Compensation As polishing pads wear down during continuous shift operation, the pneumatic/mechanical auto-wear compensation mechanism automatically adjusts the head position to maintain uniform spindle pressure on every slab.

4. Machine Configuration & Core Components
- Numerical Control Unit & Touchscreen Interface: Features a centralized NC control terminal with digital speed readout and emergency controls, enabling precise setting of linear feed rates.
- 36 kW Heavy-Duty Spindle Drive: Provides reliable power transmission to all 8 grinding and polishing spindles under continuous wet operating conditions.
- Reinforced Steel Frame (3,500 kg): Heavy structural framework absorbs operational vibrations, ensuring zero slab chatter and preventing edge chipping on delicate sintered stone or marble.
- Wireless Remote Hand Pendant (Optional): Allows operators to walk along the 7.3-meter bed length during setup, positioning, and test runs.
- Dual Operating Modes: Easily switchable between fully automatic batch processing mode and manual adjustment mode for custom edge profiles.

6. Verifiable Performance Data & Labor Reduction
To understand how the XTJ-200 replaces traditional hand-finishing, explore our guide on selecting an automatic polishing machine for high-capacity slab processing.
- Processing Capacity: Operates at linear processing speeds of 0.8 to 5.0 m/min. On standard 20 mm granite straight edges, processing speed reaches approximately 120 to 180 meters per hour.
- Labor Output Equivalent: Under normal daily processing workloads, 1 XTJ-200 unit replaces up to 15 manual stone polishers, directly reducing factory labor expenses and eliminating human error.
- Surface Gloss Consistency: Achieves consistent gloss levels above 85–95 GU (depending on stone type and abrasive sequence), exceeding hand-polishing consistency across batch orders.
7. Applications & Industrial Use Cases
- Commercial Countertop Production: High-volume edge profiling and polishing for quartz and granite kitchen tops.
- Stair Treads & Window Sills: Continuous processing of narrow strips (minimum width: 30 mm).
- Exterior Cladding & Trim Strips: Precision chamfering and slotting for ventilated stone facade panels.
For primary block processing before edge finishing, consider integrating our heavy-duty stone cutting machine models into your factory setup.
8. Customization Options
- Electrical Power Standard: Custom motor configurations for 380V / 415V / 480V (50Hz or 60Hz) regions.
- Extended Roller Tables: Infeed and outfeed roller extension modules for handling extra-long architectural slabs.
- Control System UI: Multi-language interface customization (English, Spanish, Russian, Arabic).
9. Installation, Maintenance & Spare Parts
- Installation Requirements: Level concrete foundation capable of supporting 3.5 tons, 36 kW power line connection, and a closed-loop water recirculation system capable of delivering 200 L/min.
- Maintenance Protocol: Daily flushing of abrasive debris, weekly lubrication of linear guide rails, and monthly inspection of drive belt tension.
- Spare Parts Availability: Spindle bearings, grinding disc adapters, rubber conveyor belts, and replacement diamond shaping wheels are held in stock for rapid worldwide dispatch.
