Glass beveling is a crucial finishing process used in architecture, furniture, and mirror production to create a polished, angled edge that enhances both the safety and aesthetic value of glass panels. A Glass Beveling Machine automates this process with precision, delivering consistent results for industrial and decorative applications.
A glass beveling machine is specialized equipment designed to shape the edges of flat glass into a precise angle—commonly between 0° and 45°. By removing material from the edge and polishing it to transparency, the machine transforms raw, sharp glass into smooth, elegant pieces suitable for high-end doors, mirrors, windows, and display panels.
These machines can process various glass thicknesses (typically from 3 mm to 25 mm) and are equipped with multiple grinding wheels and polishing spindles. Depending on the configuration, they can perform single-side straight-line beveling or more complex shapes for curved or round glass.
The process starts with the operator placing the glass panel on the conveyor system. The automatic clamping device secures the glass between rubber-coated rollers, ensuring steady transport along the working path. The feeding speed, generally adjustable between 0.5 and 5 meters per minute, controls both accuracy and finish quality.
Modern beveling machines, such as those developed by ADDTECH, use servo-driven conveyors and precision sensors to maintain perfect alignment during motion, minimizing edge deviation to less than 0.1 mm.
The first group of diamond grinding wheels removes excess material from the glass edge, shaping the basic bevel angle. The diamond abrasives rotate at high speeds (2800–4000 rpm) and cut the glass with uniform pressure. Coolant water circulates continuously to prevent thermal stress and ensure surface smoothness.
At this stage, the bevel width and angle are determined according to programmed parameters in the control system, allowing different edge designs such as narrow, wide, or compound bevels.
After rough grinding, finer diamond wheels refine the edge surface, eliminating visible grooves and irregularities. This stage enhances flatness and prepares the edge for polishing. In automatic machines, each grinding spindle is positioned precisely using CNC systems that compensate for wheel wear, ensuring dimensional stability over long production runs.
The polishing wheels, usually made of felt or resin bonded with cerium oxide, give the bevel edge a clear, glossy finish. Cerium oxide acts as a chemical-mechanical polishing agent that reacts with silica in the glass, producing mirror-like transparency. The polishing pressure and water feed rate are automatically controlled to achieve consistent brightness across all edges.
To prevent sharpness and improve durability, both the front and back edges of the glass are slightly chamfered or polished. Multi-spindle beveling machines can perform these operations simultaneously, ensuring that each piece exits the line ready for installation or lamination.
Modern beveling machines are equipped with PLC or touchscreen control systems that store multiple process programs. Operators can input glass size, thickness, and bevel angle, and the system automatically adjusts the spindle positions and feed rate. Some advanced models even integrate real-time monitoring and fault detection systems to ensure stable performance and high yield.

A high-quality beveling machine offers several industrial benefits:
Precision: Maintains consistent bevel width and angle with ±0.1 mm accuracy.
Efficiency: Multi-spindle systems complete grinding and polishing in one pass.
Surface Quality: Delivers optical-grade transparency suitable for mirrors and decorative panels.
Durability: Protects glass edges from chipping and cracking during handling or installation.
Automation: Reduces labor cost and minimizes human error in mass production.
To ensure continuous performance, operators should:
Regularly check the coolant flow and water filters to avoid overheating.
Calibrate the grinding wheel alignment every few weeks for dimensional accuracy.
Replace worn diamond wheels promptly to prevent surface scratches.
Keep sensors, guides, and conveyors clean from glass dust and residue.
Follow manufacturer guidelines for lubrication and power supply stability.
Routine maintenance not only extends equipment life but also keeps the optical quality of bevel edges at production standards.
Beveled glass is used across numerous sectors:
Architectural decoration: Doors, partitions, and windows that require aesthetic finishing.
Furniture manufacturing: Tabletop edges and cabinet doors with safe, smooth contours.
Mirror production: Framed and frameless mirrors in hotels, bathrooms, and retail stores.
Interior design: Custom glass artworks and luxury wall panels.
In all these cases, beveling adds dimension and visual depth to glass surfaces, reflecting light elegantly while ensuring safety.
A glass beveling machine operates through an integrated process of grinding, fine finishing, and polishing to create clean, angled edges that enhance both beauty and functionality. From the precision mechanics of its spindles to the automation of its control systems, each part of the machine contributes to the production of premium glass components.
