Diamond scribing wheels are precision cutting tools designed for accurate scribing and separation of brittle materials. They are widely used in display panel manufacturing, semiconductor glass processing, and touch panel glass cutting, where high consistency, clean scribing lines, and minimal chipping are required.
Our diamond scribing wheels are available in toothed edge and full-edge (continuous edge) designs to meet different glass thicknesses, cutting depths, and production stability requirements.
The toothed diamond scribing wheel features micro-tooth cutting edges that provide controlled penetration and stable crack initiation during scribing.
Key Features
Micro-tooth edge design for stable scribing force
Good balance between cutting efficiency and tool life
Suitable for standard and medium-precision glass scribing
Reliable performance in mass production
Recommended Applications
TFT-LCD display glass
Touch panel glass
Standard display glass substrates
The full-edge diamond scribing wheel has a continuous cutting edge around the entire circumference, ensuring smooth and uninterrupted scribing lines.
Key Features
Continuous edge design for superior line consistency
Higher stability and cutting uniformity
Reduced chipping and improved edge quality
Ideal for high-precision and ultra-thin glass processing
Recommended Applications
OLED / AMOLED display glass
Thin and ultra-thin glass substrates
Semiconductor glass and high-precision optical glass
