7+14 Stone Belt Edge Polisher for Flat, Bevel & Bullnose Edges
High-Precision Edge Grinding and Polishing Solution for Marble, Granite & Engineered Stone
In today’s competitive stone fabrication industry, edge quality is no longer optional—it’s a defining factor of product value. Whether you are producing kitchen countertops, vanity tops, wall cladding, or ceramic slabs, clean, consistent, and high-gloss edges are critical.
The 7+14 Stone Belt Edge Polisher is a professional-grade stone edge grinding and polishing machine designed to deliver flat edges, straight edges, 45° bevels, and bullnose profiles with outstanding efficiency and repeatable precision. Built for marble, granite, engineered stone, and ceramic tiles, this machine is trusted by medium and large stone processing plants worldwide.
What Is a 7+14 Stone Belt Edge Polisher?
The 7+14 configuration refers to:
- 7 grinding and profiling spindles for rough grinding, chamfering, grooving, and shaping
- 14 polishing heads for fine polishing with multi-grit water polishing pads
This combination allows continuous processing from rough grinding to mirror polishing in a single pass, dramatically improving productivity while reducing labor and consumable costs.
Materials You Can Process
This edge polishing machine is engineered for a wide range of stone materials, including:
- Marble
- Natural stone
- Granite
- Engineered stone / quartz
- Artificial stone
- Ceramic and porcelain slabs
It handles thicknesses from 6 mm to 40 mm and supports narrow pieces as small as 60 mm, making it ideal for both standard slabs and specialty components.
Edge Types & Profiles Supported
This machine is designed to cover nearly all mainstream stone edge requirements:
- Flat straight edges
- Polished straight edges
- 45° upper bevel edges
- 45° lower bevel edges
- Bullnose edges
- Profiled and shaped edges
- Grooved edges
- Laminated and mitered worktops
It can process thick slabs, ultra-thin slabs, and glued or laminated pieces, such as mitered or built-up kitchen countertops.
Spindle Configuration Overview
Rough Grinding & Shaping Units
-
1 Diamond Edge Grinding Wheel
Positioned at the front of the machine for aggressive rough grinding and material removal. Diamond tooling ensures long service life and stable performance.
-
1 Grooving Spindle
Dedicated unit for slotting and groove processing.
-
Upper 45° Chamfer Spindles
Ensures precise and symmetrical top bevel edges.
-
1 Lower 45° Chamfer Spindle
For accurate bottom beveling.
-
2 Diamond Profiling Spindles
Used for bullnose and custom profile shaping before polishing.
Fine Polishing Units
14 Independent Polishing Heads
Each head uses water-fed polishing pads with different grit levels, enabling gradual refinement from matte to high-gloss finish.
Advanced Mechanical & Structural Design
Heavy-Duty Steel Construction
- Electro-welded steel frame, fully machined by milling centers
- Exceptional rigidity ensures vibration-free operation
- Long-term dimensional stability even under continuous industrial use
Anti-Corrosion Protection System
All machine components undergo a multi-stage surface treatment:
- Sandblasting
- Metallization
- Industrial painting
Painted covers receive cataphoresis treatment, while:
- Main covers are made of stainless steel
- Critical components use stainless steel protection plates
This guarantees excellent corrosion resistance in wet stone-processing environments.
Conveyor Belt & Slab Holding System
- 400 mm wide conveyor belt
- Stainless steel sliding plates for smooth transport
- Variable feed speed from 0–6 m/min, adjustable via control panel
Pneumatic Slab Locking System
- Polishing without a contrast bar is possible
- Pneumatic pistons lock slabs securely during processing
- Dual pressure roller bars driven by air cylinders ensure stability
PU Pressure Rollers
- High-elasticity PU material
- Strong grip without damaging slab surfaces
- Maintains consistent polishing pressure across the entire edge
Independent Polishing Head Control
Each polishing head operates independently and is controlled by its own pneumatic cylinder, allowing:
- Consistent polishing pressure
- Better surface finish
- Reduced edge burn or uneven gloss
Additional features include:
- Individual water supply for each polishing head
- Continuous flushing of debris during processing
- Snail-lock polishing pads for fast pad replacement
All polishing motors are protected by stainless steel covers, significantly reducing the risk of water and slurry damage.
User-Friendly Control & Operation
- Arm-mounted control box for flexible positioning
- Clear layout for easy parameter adjustment
- Simple structure for easy maintenance
- Extractable support bar for oversized slabs
Designed for efficient daily production with minimal operator training.
