Honghe Machinery
High-performance vertical and straight-line glass edging machinery engineered for high precision, low chatter, and zero-defect edge profiles.
Delivering Micron-Level Tolerances, Superior Surface Roughness ($R_a < 0.15 \mu m$), and Unmatched Operational Reliability
Glass flat edging is not merely a cosmetic finishing process; it is a foundational step in structural glass engineering, display manufacturing, and photovoltaic panel assembly. In high-stress applications, un-edged glass contains structural micro-fissures along its cut perimeter. Under thermal load, mechanical bending, or tempering sequences, these sub-surface micro-cracks propagate into catastrophic structural failures.
Our flat edging machinery utilizes multi-stage diamond wheel kinematics combined with resin-bonded and polishing arbors to systematically remove edge defects. By transforming raw, fractured glass edges into smooth, arris-bevelled or flat polished profiles, our equipment enhances edge mechanical strength by up to 300%, meeting rigorous international standards including ISO 12543, EN 12150, and ASTM C1048.
Daejeon, known as the Silicon Valley of South Korea and home to Daedeok Innopolis, hosts over 1,400 research institutes, high-tech manufacturing facilities, and R&D centers. The regional demand for specialized glass fabrication equipment is driven by key tech clusters:
As a leading supplier for Daejeon, Nanjing Honghe Glass Machinery provides localized technical configurations, direct field integration support, and custom CNC parameters tailored to South Korea’s demanding manufacturing specs.
Navigating Industry 4.0, Energy Efficiency, and Precision Machine Kinematics
Our machines feature high-frequency motorized spindles direct-coupled to diamond grinding wheels. Eliminating belt vibration ensures sub-micron surface finish consistency, reducing wheel dressing frequency by 40% and preventing micro-chattering marks on bevels.
Equipped with Schneider and Siemens PLC automation, our systems constantly monitor current consumption per spindle to automatically compensate for diamond wheel wear. Operators control operations via an intuitive multilingual touchscreen interface.
Engineered to meet South Korean KCs certification standards and European CE directive 2006/42/EC. Our water recovery systems feature high-vortex sludge separation to meet local Daejeon environmental discharge mandates.

Technical insights for plant directors, procurement managers, and glass processing engineers in Daejeon
Our edging machines utilize heavy-duty cast-iron bases with precision-ground synchronous conveyor tracks. For high-tech applications in Daejeon (such as cleanroom viewing panels, electronic substrates, and display glass), our systems deliver vibration-free grinding with surface roughness ratings below Ra 0.15 µm. This minimizes micro-cracking and ensures extreme structural stability during tempering or cleanroom deployment.
A 9-spindle straight-line edger typically utilizes 2 diamond wheels for coarse flat grinding, 2 diamond wheels for fine flat grinding, 2 bevel arris wheels (top/bottom), 2 resin polishing wheels, and 1 dedicated final polishing wheel (such as CE-3 or felt wheel with cerium oxide). This sequence allows complete edge grinding, seaming, and mirror polishing in a single pass at speeds up to 5+ m/min.
Yes. Models such as our 9-Motor Variable 45 Degree Chamfer Miter Edging Machine feature a swiveling front beam structure. Operators can adjust the spindle gang angle smoothly between 0° (flat edge) and 45° (miter bevel) via digital encoder readouts, allowing precise corner joints for frameless glass facades and structural glass boxes.
We recommend daily flushing of coolant nozzles to remove glass swarf, weekly checking of conveyor chain tension and auto-lubrication reservoirs, and monthly inspection of wheel spindle runout. Using genuine Honghe diamond wheels and proper coolant concentration extends wheel service life by up to 35%.
