Product Overview
The Glass Double Edger Grinding Machine is designed for simultaneous processing of two parallel edges of flat glass and mirrors. Its dual-side structure uses six grinding motors per side, allowing rough grinding, fine grinding and edge finishing in a continuous pass. A CNC-machined heavy-duty motor base, dual ball screws and linear guides provide stable positioning during production.

Grinding Capability
The machine performs double-side edge grinding in one feeding operation, reducing repeated handling compared with single-edge processing. Water cooling is used during grinding to control heat and remove glass debris from the processing area. The grinding system is suitable for production lines requiring consistent edge dimensions and repeatable processing of batches of flat glass.
The standard machine is equipped with 6 grinding motors on each side, providing a total of 12 grinding positions. The grinding-head arrangement can be assigned to different processing stages according to the required edge result, such as:
- Rough grinding for controlled material removal
- Fine grinding for dimensional and surface refinement
- Chamfering or arris processing
- Polishing where a finished edge is required
Typical industrial configurations use diamond wheels for material removal and resin or polishing wheels for subsequent finishing stages. Exact wheel types and motor assignments should be matched to the glass type, edge profile and required surface finish.
Automation & Line Integration
A PLC-controlled system with a 7-inch rotating touchscreen allows operators to set and adjust processing parameters from the machine control panel. Forward and reverse motor control is provided for grinding adjustment and operation.
The machine can be combined with straight-line transfer tables and upstream/downstream glass-processing equipment to create a continuous production flow. For higher-throughput lines, industrial double-edging systems can also incorporate automatic glass measurement, servo-driven width adjustment and transfer stations.
Applications
The machine is suitable for batch processing of:
Architectural and building glass
Residential glass
Automotive glass
Mirrors
Flat glass requiring parallel-edge grinding
Customization
Machine configuration can be adapted to production requirements such as:
- Glass thickness and width range
- Grinding and polishing wheel configuration
- Edge-processing requirements
- Electrical standards and voltage
- Transfer-table arrangement
- Production-line integration
Testing & Quality Control
Before shipment, the machine should be checked for mechanical alignment, grinding-head positioning, conveying stability, electrical functions, lubrication, water circulation and safety controls. Trial processing should verify glass dimensional accuracy, parallelism, diagonal tolerance and edge finish against the agreed technical requirements.
The machine structure uses a CNC-machined heavy-duty motor base, while linear guides and ball screws provide controlled movement of the grinding assemblies. Operational testing should also confirm that the machine runs without abnormal noise or instability under normal working conditions.
FAQ
Q: Can it process coated or Low-E glass?
A: It can be configured for suitable coated-glass applications, but the coating position and edge-deletion requirements must be confirmed before production. For Low-E or other coated glass, sample testing is recommended to verify coating removal, edge quality and wheel selection.
Q: How often do the grinding wheels need to be replaced?
A: Wheel life depends on glass type, grinding allowance, feed rate, wheel specification and production volume. Diamond wheels generally provide long service life for material removal, while finishing wheels require replacement or dressing according to wear and the required edge finish.
Q: What water system is required for operation?
A: Grinding requires continuous cooling and removal of glass particles. A recirculating water system with filtration or settling is commonly used to reduce water consumption and prevent abrasive glass residue from returning to the grinding zone.
Q: What foundation and installation conditions are required?
A: The machine should be installed on a level, load-bearing floor with sufficient space for glass loading, unloading, maintenance and water-system connections. Final foundation requirements, machine positioning and utility connection points should be confirmed from the installation drawing before site preparation.
Q: What information is required for a machine quotation?
A: A quotation normally requires the target glass thickness and size range, expected production volume, required edge profile and finish, glass types or coatings, destination country, electrical standard and any required upstream or downstream equipment.
Q: What is the delivery time for the glass double edger?
A: The standard delivery time is 60–90 days after order confirmation. The schedule covers machine production based on the confirmed technical configuration and should be considered together with the agreed inspection, packaging and shipping arrangements.
Q: What payment methods are available for the machine?
A: We accept T/T, Western Union and PayPal, along with other convenient payment methods subject to order requirements.
Q: What delivery terms are available for international orders?
A: The standard delivery term is FOB Shanghai. We also offer EXW, CFR and CIF according to the buyer's logistics requirements.
