the critical importance of position synchronization for superhard material synthesis and press equipment safety stems from the specific physical requirements of working in ultra-high pressure and high-temperature environments.

1. Ensuring "Three-Center Alignment" to Maintain Force Balance The core prerequisite for the normal operation of a hexahedral press is that the structural center (the geometric center of the equipment), the force convergence center of the anvils (the point where the forces from the six hydraulic cylinders converge), and the mass center of the synthesis material in the synthesis cavity must coincide as much as possible. Position synchronization is the key method for controlling the "anvil force convergence center"; only through the precise synchronization of all hydraulic cylinders can these three centers remain consistently aligned.

2. Guaranteeing Equipment Safety and Preventing Catastrophic Damage If position synchronization fails, causing the aforementioned centers to misalign, severe eccentric loads will occur, leading to destructive consequences for the equipment:

 Preventing Cylinder Pulling: Desynchronization causes excessive lateral forces on the hydraulic cylinders, triggering "cylinder pulling" accidents, which are mechanical damages to the cylinder wall and piston rod.

Protecting Anvils: Anvils are expensive, brittle, and critical components. Poor synchronization results in uneven force distribution on the anvils, easily causing anvil damage.

Managing Risks in Large-Scale Equipment: As presses grow larger (e.g., cylinder diameters reaching 1000mm, with rod weights exceeding 3 tons), differences between cylinders increase. Without high-precision synchronization control, the massive inertial and gravitational differences significantly increase the risk of equipment damage.

3. Ensuring the Stability of the Synthesis Process Environment The synthesis of superhard materials (such as diamond) must be conducted in an extreme environment that is sealed, under ultra-high pressure, and at high temperatures.

Preventing Seal Failure: The six hydraulic cylinders must move in coordination to form and maintain the sealed synthesis cavity. If positions are not synchronized, the stress structure of the synthesis cavity will be destroyed, leading to seal failure. Once the seal fails, the high-pressure environment cannot be maintained, causing the synthesis experiment to fail and potentially triggering safety accidents like high-pressure jetting.

Improving Synthesis Quality: Only when the anvils from six directions advance with extremely high positional accuracy can uniform pressure distribution within the synthesis cavity be ensured. This satisfies the strict conditions required for superhard material growth, thereby avoiding synthesis failures or quality defects caused by poor synchronization,.

In summary, high-precision position synchronization is not only a safety barrier preventing damage to hardware (such as hydraulic cylinders and anvils) but also a necessary process condition for constructing a stable high-pressure sealed cavity and ensuring the successful synthesis of superhard materials.
