ROCKSHARP HD-SP
Upright Intelligent Polishing Machine
The HD-SP is a high-performance automatic edge polishing machine designed for processing ceramic tiles, porcelain slabs, marble, granite, quartz stone, and engineered stone. Equipped with 12 grinding and polishing stations, the machine integrates edge trimming, chamfering, bottom grinding, profiling, and polishing into a single continuous production process.
With a processing speed of up to 0.7-5 m/min and intelligent multi-wheel configuration, it delivers high productivity, excellent edge quality, and consistent processing accuracy for modern stone fabrication facilities.
Types of stone that can be processed
The HD-SP Intelligent Stone Edge Polishing Machine is suitable for processing marble, granite, quartz stone, engineered quartz, sintered stone, porcelain slabs, and other stone materials. It is widely used for edge finishing and polishing of kitchen countertops, vanity tops, island tops, tabletops, coffee tables, TV cabinet tops, reception counters, service desks, and other custom stone products, delivering high-quality edges and consistent polishing results.
Superior edge processing
The HD-SP Vertical Edging Machine supports a wide variety of decorative edge profiles commonly required in stone fabrication projects. Available profiles include:
- Straight Edge
- Beveled Edge
- 45° Chamfer Edge
- Pencil Edge
- Bullnose Edge
- Half Bullnose Edge
- Ogee Edge
- Waterfall Edge
- Decorative Custom
- Profiles
The replaceable profiling wheel system allows fabricators to switch between different edge styles efficiently.
Key Components
Engineered for precision cutting with stable performance, clean edges, and intelligent control.
Multi-Stage Grinding System
The machine adopts a professional 12-wheel grinding configuration that enables multiple processing stages to be completed in a single pass.
The processing sequence includes:
- Rear-edge cutting
- 45° chamfer grinding
- Bottom edge grinding
- Replaceable profiling wheel shaping
- Fine grinding
- High-gloss polishing
This arrangement ensures smooth material flow while achieving excellent dimensional accuracy and edge consistency.
High Productivity Performance
Designed for continuous production, the machine operates at adjustable speeds ranging from 0.7 to 5 meters per minute, allowing operators to optimize output according to material hardness and surface finish requirements.
The automatic conveyor feeding system minimizes manual handling and significantly increases production efficiency compared with traditional edge polishing methods.
Superior Polishing Quality
Multiple polishing wheels work sequentially to remove grinding marks and improve surface smoothness. The final polishing stage produces a high-gloss finish that closely matches the original surface appearance of the stone or porcelain slab. This ensures premium-quality edges suitable for:
Kitchen countertops
Vanity tops
Stair treads
Window sills
Wall cladding panels
Furniture stone components
