PHU SON Corporation delivers high-speed HISENG glass double-edging polishing machine at TIN HUNG GLASS factory. The machine features an automatic pneumatic cylinder polishing stone compensation function controlled via PLC (HISENG’s proprietary design) with outstanding advantages:

  • Perfect product gloss quality due to the technical requirement of polishing, which requires the elasticity of the grinding wheel via a pneumatic cylinder.

  • Grinding paths are absolutely free of unpolished spots due to the gloss compensation feature being automatically set via PLC.

  • Grinding paths are absolutely free of unpolished spots due to the gloss compensation feature being automatically controlled via PLC. [Note: This sentence is repeated in the original text]

  • Simple operating principle helps keep the entire production line uncomplicated in operation, stable, and durable.

  • Very attractive investment budget.

  • The machine has a QR code scanning function, allowing it to automatically receive and execute production orders without any manual production order data entry operation.

  • Oversized glass detection function: The entrance of the moving edge grinding assembly is equipped with an oversized glass detection device (also known as “surplus margin detection” or “secondary inspection”). The system will automatically adjust the speed to a reasonable edge-grinding range based on the excess value range to prevent chipping or glass breakage while protecting the motor from overloading. If the dimensions exceed the allowed limit, the machine will automatically stop.

  • Energy-saving, flexible, and efficient function, helping to reduce energy consumption when the machine runs idle.

  • Equipped with network diagnostic functions, enabling remote connection with the manufacturer’s engineering team for troubleshooting or program upgrades.

  • Communication ports can connect with equipment from preceding and subsequent stages, and exchange data with smart manufacturing management systems ERP and MES.

  • The currents of the 24 grinding head motors are displayed directly on the touch screen. Current values are recorded directly via data transmission rather than taking indirect signals from the inverter, making the displayed data more accurate and updated in real-time.

  • All electrical components meet European CE standards. The electrical wiring system is also implemented according to CE standards. Each motor is equipped with an independent overload protection relay, ensuring stable and safe machine operation.

  • Servo motors, servo controllers (drivers), inverters, and transformers are installed in a separate compartment to avoid signal interference.

  • Utilizing the latest generation Inovance MD800 inverter system, each motor is independently controlled, helping to reduce mutual influence between motors. Automatic control mode can be set while monitoring the working status of each motor, thereby transmitting data to the central computer to analyze motor operating data.

  • Automatic wear compensation function for polishing stones using pneumatic cylinders: In automatic machining mode, when the glass moves to the position opposite the grinding stone, the locking mechanism is released, and the pneumatic cylinder applies a preset pressure to the glass. Before the glass leaves the machining position, the locking mechanism locks to maintain the current position of the grinding stone. This process is repeated automatically and intelligently without manual intervention.
