Felix Glass Upgrades CNC Chamfer Workshop for Precise C/J Edge Glass Production
Felix Glass Upgrades CNC Chamfer Workshop for Precise C/J Edge Glass Production
Felix Glass has officially completed a comprehensive upgrade to its CNC precision chamfer and edge polishing workshop, targeting the core manufacturing process for C-type straight chamfer and J-type arc chamfer tempered glass. The upgraded production line solves long-standing industry problems such as inconsistent edge dimensional tolerance, uneven polishing texture, and residual micro burrs, further stabilizing industrial-grade edge quality for customized HMI touch screen glass.
As industrial HMI equipment becomes increasingly compact, narrow-bezel, and streamlined, glass edge precision and surface finish have become critical indicators affecting assembly clearance, structural stability, and overall equipment aesthetics. Ordinary 3-axis single-pass grinding often leads to unbalanced chamfer depth, irregular arc transition, and post-tempering edge chipping, which cause assembly gaps, touch film extrusion damage, and latent cracking risks during long-term equipment vibration.
Key Workshop Upgrade Highlights
1. 5-Axis High-Precision CNC Milling & Grinding System
The workshop introduces new multi-linkage CNC grinding equipment supporting full-path synchronous correction for straight C chamfer and arc J chamfer profiles.
- Dimensional tolerance stabilized within ±0.03mm
- Uniform chamfer width & arc radius on four edges
- Eliminates diagonal deviation and asymmetric edge defects
2. Three-Stage Progressive Mirror Polishing Process
All C/J edge processing adopts strict three-stage production flow:
Rough grinding → Fine calibration grinding → Mirror finish polishing
- C-type edge roughness Ra ≤ 0.8μm
- J-type arc edge roughness Ra ≤ 0.4μm
- Zero burrs, zero micro cracks, zero sharp transition lines
3. Independent Parameter Database for Industrial HMI Specifications
Built exclusive process parameter library for mainstream industrial chamfer standards:
- C0.3 / C0.5 / C0.8 / C1.0 flat bevel standards
- R0.5 / R1.0 / R1.5 / R2.0 arc chamfer standards
- Automatic parameter matching ensures consistent batch performance for repeated OEM orders.
4. Pre-Tempering Edge Full Inspection Mechanism
Add dedicated edge profile scanning station before chemical tempering. All unqualified deformed edges are corrected in advance, greatly reducing post-tempering edge stress concentration and improving finished product yield.
Manufacturing & Customer Value Improvement
- Higher assembly compatibility for narrow-bezel industrial HMI structures
- J-type arc edge effectively buffers vibration impact, reducing glass cracking rate
- Smooth mirror edges protect touch sensor layers during lamination
- Uniform industrial appearance for high-end medical, marine and outdoor terminal equipment
- Stable repeatable quality for long-term annual frame contract orders
