In the high-stakes world of precision machining, where micron-level accuracy is required along with increasing energy costs, the hydraulic system can no longer be an afterthought. It must be a source of reliability, efficiency, and quiet operation. The TOKIMEC SQP series double pump configuration is engineered to meet these exacting demands, making it the ideal hydraulic heart for a wide range of machine tools, including machining centers, grinders, and CNC lathes.

Product Description

Applications

Machine tools require hydraulic power for essential functions such as spindle clamping, tool changer operation, chuck clamping, and tailstock advancement. These functions often have different requirements: some need high flow for quick movement, while others require sustained high pressure for holding. A conventional single pump must be sized for the highest flow demand, leading to inefficient operation and excessive heat and noise during low-flow periods. The SQP double pump effectively addresses this issue by distributing these tasks between its two pump sections.

One section, typically the larger unit, is designed for high-flow, low-pressure tasks such as indexing the tool changer arm or rapid traverse of a tailstock. The second, smaller section is specifically calibrated to supply consistent, high-pressure power needed for securely holding a tool in the spindle or a workpiece in the chuck. This intelligent division of labor is controlled through efficient load-sensing systems, ensuring each pump section delivers only the required flow and pressure, significantly reducing energy use and heat production.

Beyond efficiency, the SQP double pump is designed to offer the stability needed for precise operations. Its advanced engineering reduces pressure fluctuations and flow disturbances, resulting in smoother and quieter performance of hydraulic systems. This leads to better surface quality and higher part consistency. Additionally, the pump's quiet operation is a key feature of the SQP series, contributing to a more pleasant working environment and compliance with modern noise regulations.
