Uses a fixed displacement pump to continuously deliver a stable flow under conditions with minor load variations.
Equipped with a pressure-compensated variable pump, it can automatically adjust the output flow according to the system requirements.
Integrates a servo motor and intelligent drive system, and adjusts the motor speed in real time according to hydraulic requirements.
Integrated Hydraulic and Electrical Systems
The hydraulic power unit for machine tools is a part of the overall layout of the machine. We can integrate hydraulic components, electrical control and signal interfaces into a single unit. This makes your installation much simpler and requires less wiring work. When your machine is delivered to the customer, less system verification will be required. At the same time, this can also leave more usable space for the tool magazine, the automation module and the internal layout of the machine tool.
Multi-Stage Oil Cleanliness Control
The stability of hydraulic systems is closely related to the cleanliness of hydraulic oil, especially in machine tools that require long-term continuous processing. Our machine tool hydraulic power pack is equipped with a graded filtration system to intercept pollutants before they reach sensitive components. Cleaner hydraulic oil means less maintenance, longer component lifespan, and lower risk of production interruption caused by hydraulic contamination.
On-Demand Hydraulic Power Supply
Unlike traditional hydraulic stations that maintain a constant output, our machine tool hydraulic power pack can adjust the hydraulic output according to actual working conditions. When the clamping, releasing or auxiliary actions are not performed, unnecessary energy consumption can be reduced. This on-demand hydraulic power supply method helps to reduce your operating costs. This can also reduce the internal heat generation in the hydraulic system, which helps the machine tool operate stably for a long time.
Provides hydraulic power for fixture clamping, pallet exchange, and auxiliary mechanisms, helping the machining center maintain consistent operation throughout multiple production cycles.
Milling operations typically require frequent adjustment of fixtures. Our hydraulic power pack provides controllable hydraulic power for swing clamps, fixture cylinders, and positioning devices, improving clamping consistency and reducing repetitive calibration work.
Our machine tool hydraulic power unit can drive the hydraulic chuck, tailstock and workpiece clamping system, meeting the positioning requirements for different batch turning processes.

Not necessarily. If your machine has frequent clamping actions or high instantaneous flow requirements, you can choose to configure an accumulator. It can store hydraulic energy and quickly release it when needed, reducing pressure fluctuations.
Before discussing the custom hydraulic power pack for machine tools, we suggest that you prepare the necessary information such as working pressure, flow requirements, number of actuators, operating cycle, installation space, and power supply conditions in advance. The more complete the information you provide, the more helpful it is to quickly determine an appropriate hydraulic solution and avoid unnecessary redesign later.
In most cases, it is possible. We can reserve flow capacity and expand valve positions or interfaces during the design stage of the hydraulic power pack for machine tools. This makes it convenient for you to add new fixtures, automation modules, or auxiliary mechanisms in the later stage. Considering expansion requirements in advance can reduce your costs during subsequent renovations and improve the long-term utilization value of the machine.
You should prioritize using a fuel tank breather with better sealing performance. Regularly clean the area around the fuel tank and oil filling port to prevent metal dust from entering the system with air or during refueling. At the same time, monitor the pressure difference changes of the filter element according to the running time of the equipment. Do not replace the filter until it becomes clogged.
