It is used in die finishing and adjustment, especially in the process of manufacturing and maintaining large and medium-sized stamping dies, to complete the die grinding, precise debugging and processing.

According to the type of mold and the different processing, the hydraulic press is divided into two types of structure: with the mold turnover device (flip 180°) and without the mold turnover device. Due to the high requirements on the stroke control process, the press with the stroke fine-tuning function, step (or inching) stroke up to 0.02-0.05mm/ time, the fine-tuning mode has mechanical four-point fine-tuning, hydraulic servo fine-tuning and no pressure down fine-tuning three ways.
