Bosch Rexroth Corp.'s rapidstar supply unit for metalworking coolant is comprised of a range of low- and high-pressure valve blocks, filters and screw pumps for customized pressure supply in remote systems. By using complete valve blocks, the supply system reduces the required piping and simplifies mechanical setup, the company reports. With the company's KST booster, the unit moves high-pressure coolant generation into a machine's hydraulic unit when through-coolant tools are applied.
