Product Introduction
High-Precision Stepped Cover Glass for Demanding Applications
why Stepped cover glass important?
We specialize in the precision fabrication of High-Precision Stepped Cover Glass for demanding applications. Our key processing strengths include:
Advanced CNC Capabilities: Using 5-axis CNC grinding systems, we achieve step depth tolerances of ±0.05mm and positional accuracy of ±0.1mm, ensuring seamless integration with device housings for wearables, automotive displays, and industrial panels.
Complex Step Designs: Unlike standard cover glass manufacturers, we routinely produce multi-level stepped structures, including stepped recesses for flush mounting and raised steps for lens protection. Custom step heights, angles, and transition profiles are fully supported.
Superior Edge Quality: Our proprietary step-edge polishing process eliminates micro-cracks and stress risers, reducing breakage risk during assembly and field use. The result is an optical-grade edge finish comparable to polished display glass.
End-to-End In-House Processing: From CNC grinding to chemical strengthening and optical coating (AG/AR/AF), all processes are performed in-house. This integrated approach ensures tighter quality control, faster lead times, and lower risk of damage during handling.
Rigorous Quality Assurance: Every batch is inspected using high-resolution optical measurement systems and surface profilometers to verify step geometry, edge integrity, and dimensional conformance to your CAD drawings.
Whether your application demands ultra-tight tolerances, complex stepped contours, or robust mechanical performance, our manufacturing process is engineered to deliver consistently reliable Stepped Cover Glass for your most challenging designs.

FAQ
Q:What is the minimum step height you can achieve on Stepped Cover Glass?
A:Our minimum achievable step height is 0.1mm with a tolerance of ±0.05mm. For most applications, we recommend a step height of at least 0.15mm to ensure optimal structural integrity and consistent manufacturing yield. Step heights up to 2.0mm are available for thicker glass substrates.
Q:Can you produce stepped cover glass with multiple step levels on the same piece?
A: Yes, we specialize in multi-level stepped designs. We can produce glass with two, three, or more step transitions on a single workpiece. Common applications include smartwatch housings requiring both a recessed center area and a raised bezel, or automotive displays with complex mounting interfaces.
Q:How do you ensure the step position accuracy relative to the glass edge?
A:We use precision CNC machining with optical alignment systems. Step position accuracy is maintained at ±0.10mm relative to glass edges or reference holes. Each batch is verified using CMM (Coordinate Measuring Machine) and high-resolution vision inspection systems to ensure consistent alignment.
Q:Can you apply anti-fingerprint (AF) coating on the stepped surface without edge peeling?
A:Yes. Our coating process is specifically optimized for stepped geometries. We apply AF, AR, or AG coatings after step machining and chemical strengthening. The coating is applied uniformly across both flat and vertical step surfaces. We perform tape peel tests and abrasion tests (≥ 3000 cycles) to verify coating adhesion with no edge peeling.
