Hualong Machinery Stone slab calibrating machine,It is suitable for equal-thickness processing and surface pre-treatment of granite, marble and artificial stone slabs. It can effectively remove saw marks and prevent wave deformation on slab surfaces. The processed slabs feature high flatness and uniform thickness.
The stone slab calibrating machine can connect with automatic continuous polishing machines to form a complete stone polishing production line, greatly improving slab processing capacity and finished product quality.
It is available in 2-head, 4-head and 6-head models to meet different factory capacity requirements. We can also customize combined calibrating and polishing all-in-one machines upon customer requests for more efficient operation and processing.
Core Features
Precise thickness calibration & grinding: Completely removes saw blade marks, ensures uniform slab thickness, laying a solid foundation for subsequent polishing.
Continuous assembly-line operation: Conveyor feeds slabs continuously without shutdown. Higher number of grinding heads delivers greater production capacity.
Heavy-duty welded frame: Robust steel structure with vibration resistance, keeping the machine stable and durable under heavy-load working conditions.
Modular grinding head configuration: Each grinding head is equipped with a 22kW motor, offering strong cutting power for hard granite.
Seamless production line connection: Can be directly matched with automatic polishing machines to realize a complete workflow of "cutting – calibrating – polishing.
Processed Slabs: Granite, marble, artificial stone, quartz stone
Finished Products: Floor tiles, wall slabs, countertop blanks, vanity top blanks
Application: Medium and large stone processing factories, slab polishing production lines, stone fabricators
