This infrared laser technology works in conjunction with the PLC control system and encoder-based division mechanism to deliver exceptional dimensional accuracy. For stone fabricators, this translates to higher-quality finished products, reduced material waste, and increased customer satisfaction through precision craftsmanship.
What is an encoder system in bridge saws?
The encoder-based slab dividing system is a precision technology that ensures exceptional dimensional accuracy when cutting stone materials into multiple pieces. This advanced system functions through the following mechanisms:
• Ultra-high precision rotary encoder: This device tracks the exact position of the cutting blade with microscopic accuracy throughout the cutting process
• Digital position monitoring: The system continuously measures and verifies the cutting head's location, ensuring precise dimensional control
• Automatic compensation: Real-time adjustments correct for any mechanical variations or movement deviations during operation
• Programmed division parameters: Operators can set exact dimensional specifications for multiple cuts, which the system then executes with perfect consistency
• Enhanced stability: The encoder feedback loop improves overall machine stability by preventing drift or accumulating errors during extended operations
This sophisticated division system is particularly valuable for applications requiring multiple identical pieces, such as tombstone production, dimensional panels, or matched architectural elements. By maintaining precise dimensional control throughout the cutting process, the encoder system ensures that each piece meets exact specifications, reducing material waste and virtually eliminating the need for manual adjustments or corrections.
How thick can a bridge cutting machine cut?
