Full Process of Glass Mechanical Processing 

Process Overview


Raw glass → Loading → Cutting → Edge grinding & chamfering → Drilling & grooving → Washing & drying → Tempering → Coating & screen printing (Optional) → Insulated / Laminated glass processing (Optional) → Quality inspection → Packaging & warehousing


Step-by-Step Explanation


1. Automatic Loading 微信图片_20260615163011_240_8

Equipment: Loading table, vacuum manipulator, air flotation table

Function: Automatically pick and transfer glass to avoid scratches and breakage.


2. CNC Cutting微信图片_20260610140840_212_8

Equipment: Full-automatic glass cutting machine, laser cutter (for ultra-thin glass)

Function: Cut regular & special-shaped glass, holes and arcs per drawings. Accuracy: ±0.1mm.


3. Edge Grinding, Chamfering & Polishing655ad1fe-3db6-44dd-b3d5-7a2d816e22b5

Equipment: Straight-line / double-sided edge grinder, special-shaped edge grinder, chamfering machine, polisher

Function: Remove burrs and micro cracks, prevent edge chipping for better safety and appearance.


4. Drilling & Grooving  35b541f7-a41e-4e15-8f2b-8016b493de8d

Equipment: Double-head drilling machine, integrated drilling & grooving machine

Function: Process mounting holes and grooves. Aperture: 3–50mm. Up-down drilling avoids edge chipping.


5. Washing & Drying 微信图片_20260602162000_240_3

Equipment: Horizontal glass washer

Function: Remove dust, abrasives and oil. Mandatory procedure before tempering and coating.


6. Tempering 微信图片_20260615155419_235_8

Equipment: Horizontal tempering furnace

Function: Heat and rapidly cool glass to raise strength by 5–10 times. Broken glass turns into granular pieces for safety.


7. Surface Treatment (Optional)微信图片_20260615160045_236_8

Equipment: Coating machine, screen printer, drying oven

Function: Apply Low-E film, anti-fingerprint film, color patterns and logos.


8. Composite Processing (Optional)34d228e6-d7a7-4812-b702-9e4ffcb5a3dd

Insulated Glass (For doors & curtain walls)

Equipment: Spacer bender, glue spreader, insulated glass production line
Function: Double-layer sealed glass with argon filling for heat insulation, sound insulation and anti-condensation.

Laminated Glass (For railings & canopies)

Equipment: Lamination table, pre-press machine, autoclave

Function: Laminated with PVB film. Broken glass stays attached to prevent splashing.


9. Quality Inspection微信图片_20260615162729_238_8

Equipment: Stress tester, surface defect detector

Inspection items: Dimension, scratches, bubbles, tempering stress and fragment size.


10. Packaging & Warehousing

Procedure: Paper padding + foam protection + wooden/carton packaging
Function: Prevent collision damage during transportation and storage.


Useful Tips

  1. All cutting, drilling and edge processing must be finished before tempering. Tempered glass cannot be reworked.

  2. Clean glass thoroughly before deep processing to avoid defective products caused by dirt.

  3. Choose insulated glass for thermal & acoustic insulation, and laminated glass for safety protection.
