Products Details


1. Powerful Flywheel System
The flywheel is the core power component of the gang saw machine. It is supported by two heavy-duty bearing pedestals and precisely manufactured to ensure smooth and stable reciprocating movement during the sawing process.
The large flywheel design increases machine running stability, reduces vibration, and improves cutting efficiency.


2. Hydraulic Coupling Transmission System
The power unit consists of an AC motor and hydraulic coupling. The flywheel starts gradually and smoothly through hydraulic transmission, reducing impact force and improving machine stability.
The rotary movement of the flywheel is converted into linear reciprocating movement of the blade holder frame through connecting rods and crank mechanisms.
3. Double Connecting Rod Transmission Structure
The double connecting rod system provides balanced transmission force and ensures smooth movement of the saw frame during continuous operation.
The optimized mechanical structure reduces vibration and improves cutting accuracy and blade service life.
4. Articulated Rectilinear Guide System
The blade holder frame adopts Italian articulated rectilinear guide technology, which effectively reduces abrasion between moving parts.
The guide system provides high precision linear movement, easy maintenance, and lower replacement costs.


5. Heavy-duty Load Bearing Structure
The load-bearing structure consists of four vertical columns and two cross beams, providing excellent rigidity and stability during high-load cutting operations.
The strong frame structure ensures long-term accuracy and reliable machine performance.
6. Blade Holder Frame Assembly
The blade holder frame is composed of two thick welded steel plates connected by tubular side members.
The frame is guided by four precision columns, ensuring straight movement and stable blade operation during cutting.
7. Advanced Lifting Platform System
The lifting platform adopts four lead screws with precision guiding systems to ensure smooth and accurate vertical movement.
The block trolley remains stable during lifting, improving cutting accuracy and reducing operation errors.


8. Stable Block Trolley System
The block trolley is manufactured with a heavy-duty steel structure to support large marble blocks during cutting.
The reducer motor drives the trolley through chain transmission, ensuring smooth, accurate, and reliable movement.
9. Efficient Water Cooling System
The water cooling system continuously cools the diamond blades during cutting and removes waste materials from the cutting area.
It improves cutting efficiency, extends blade service life, and ensures better slab quality.
10. Intelligent Control Panel
The control panel features an intuitive design, simple operation, and low requirements for operator experience.
Main electrical components are selected from internationally recognized brands, including Schneider, Siemens, and Yaskawa, ensuring stable and reliable electrical performance.
11. Optional Motorized Transfer Trolley
The optional motorized transfer trolley improves production efficiency by automatically transferring the block trolley between loading, cutting, and unloading areas.
It reduces idle time during slab unloading and block loading, making the whole production process faster and more efficient.
