Horizontal Double Edger
Line
The high-volume workhorse of glass edge processing — 10 to 13 precision spindles per side grind both edges simultaneously at speeds up to 15 meters per minute. Built on precision ball-screw structures with servo transmission for continuous, automatic production.
How It Works
Five stages from raw edge to polished finish — the complete double-edging workflow.
Why This Double Edger
Six features that deliver maximum throughput and edge quality.
20–26 Simultaneous Spindles
Both edges are processed in a single pass with 10–13 spindles per side — delivering double the throughput of single-side edgers with half the floor space.
Up to 15m/min Speed
Industry-leading processing speed for continuous architectural glass production. Variable-speed conveyor matches spindle speed to glass thickness for optimal finish quality.
Servo-Driven Thickness Adjustment
Automatic thickness adjustment via servo motors — change from 3mm to 25mm glass without manual intervention. HMI stores preset profiles for instant changeover.
Precision Ball-Screw Structure
All grinding heads mounted on precision ball-screw guideways with linear bearings — delivering micron-level positioning accuracy and vibration-free operation at high speeds.
3-Phase Water Filtration
Closed-loop recirculating cooling system with 3-stage filtration removes glass particles down to 5μm — extending coolant life and maintaining consistent grinding quality.
HMI Preset Profiles
Store up to 100 edge profiles in the touchscreen HMI. One-tap recall loads spindle positions, conveyor speed, and pressure settings — changeover in under 60 seconds.
20–26 Simultaneous Spindles
Both edges processed in a single pass — delivering double the throughput of single-side edgers with half the floor space.
Technical Specs
Every parameter engineered for high-speed, precision edge grinding.
How It Compares
Double-side processing vs. single-side and manual alternatives.
Hanwin Double Edger leads in Throughput (95), Speed (92), and Automation (90) — delivering twice the output of single-side edgers in the same footprint.
Where It Excels
From curtain walls to furniture — one double edger, every edge grinding application.
Architectural Curtain Wall
High-Volume Production
Curtain wall glass demands perfectly parallel, polished edges at production speed. The double edger line processes both edges simultaneously, delivering consistent semi-finish to polish quality on glass from 6–25mm at up to 15 meters per minute.

Five essential maintenance practices to maximize spindle life and edge quality.
Inspect all grinding and polishing wheels for wear, chips, or glazing. Check diamond wheel segment height and replace when below minimum. Inspect polishing wheel surface for loading — dress or replace as needed.
Check coolant concentration and pH level (target 7.0–8.5). Clean or replace filter cartridges in the 3-stage filtration system. Inspect coolant nozzles for blockages and flush lines with clean water.
Verify spindle alignment using a precision straightedge and dial indicator. Check for bearing play by grasping each spindle and checking for lateral movement. Realign or replace bearings as needed.
Inspect conveyor belt tension, alignment, and surface wear. Check all drive motor mounts, couplings, and gearboxes for looseness or oil leaks. Lubricate all linear guides and ball-screw bearings.
Perform a complete machine calibration using laser alignment tools. Verify edge parallelism, thickness accuracy, and spindle speed across all heads. Update PLC software and HMI profiles. Conduct full safety system test.
Common Questions
Everything you need to know about the Horizontal Double Edger Line.
The standard configuration has 10 spindles per side (20 total). Professional and Enterprise configurations offer 12 or 13 spindles per side (24–26 total). More spindles allow finer grit progression and higher-quality edge finishes.
The machine processes glass from 3mm to 25mm thickness. Servo-driven automatic thickness adjustment (Professional/Enterprise) allows quick changeover without manual intervention — the HMI stores preset profiles for instant recall.
With 10 spindles/side, you get semi-finish to light polish quality. With 12–13 spindles/side, full polish edge quality is achievable. The final edge finish depends on the number of polishing spindles, wheel grit sequence, and processing speed.
Processing speed is up to 15 meters per minute, depending on glass thickness, edge profile, and finish quality. The variable-speed conveyor automatically adjusts to match the optimal speed for each glass configuration.
Standard installation takes 5–7 days including mechanical setup, electrical connection, water system commissioning, PLC programming, and operator training. Our engineers also assist with upstream and downstream line integration.
Daily wheel inspection, weekly coolant system service, monthly spindle alignment check, quarterly conveyor and drive service, and annual full calibration. Detailed maintenance schedules are provided in the operation manual.
