Although the tool change takes only a few seconds, but the machine is unproductive during that time. The shorter the changing operation, the lower are the processing costs. A hydraulic releasing of both the spring force and the self-locking action of the taper lock offers considerable advantages. Using a high flow rate and a suitable pressure the releasing process takes place in a very short time. The high flow rate is thus provided in the featured special blocks of HAWE by a directly attached accumulator a...
Manufacturers that supply machine tools and machining centers in the automotive industry can incorporate the proven compact units in their machines. In line with the car manufacturers' job specifications, the temperature and level monitor as well as the filter's pollution control are fitted with an early warning function. Thus, necessary interventions are signaled early on to the machine operator so that he can implement these in the scheduled down-times, thereby increasing the availability of the machines....
The savings in space and energy with compact power packs of HAWE Hydraulik are well-known. Up to now the seated valve specialist from Munich added another way to save installation space in the directly mounted valve banks. Directional seated valves of the NBVP series are now available in multiple symbols as 2in1 version with full functionality. Specifically, two valves are installed in one valve block and share one sub-plate. These are electromagnetically actuated. An energy saving 8 watt version is also av...
For large machining centers hydraulic weight balancing of spindle heads and/or work piece tables pays off. Because HAWE Hydraulik's cleverly arranged systems cut down the processing center's consumption of electricity and resources. They contribute not only toward energy efficiency in production, but also lower the machines total costs of ownership (TOC). What's more, when hydraulically counterbalanced, the motors for the vertical axes of spindle head and work piece table can be dimensioned significantly sm...
Directional seated valves of series NBVP from HAWE Hydraulik SE, Munich, are now available with a contactless inductive proximity switch. In this version, an inductive proximity switch monitors the switching operations of the valve. The advantage of this technology is that the safety function is maintained regardless of the number of switching operations. Since a proximity switch has no mechanical parts it is not subject to wear which saves the need for regular replacement. The position monitoring signals ...
The FlexUnit is a fully modular designed hydraulic power unit for industrial use. Heart of the system are either the tried and tested radial piston pumps from HAWE Hydraulik which are designed for high operating pressures up to 700 bar or especially low noise gear pumps for lower pressures up to 280 bar. Combinations of radial piston and gear pumps for the construction of a two-stage unit (high-pressure / low-pressure) are also an option provided in the modular design kit.
The special feature of the ...
Hydraulic power units are regarded as reliable subsystems within machine tools and manufacturing plants. Regular maintenance prevents unplanned failures and reduces downtime. Today the essential functions are already pre-warned monitored by switches. Thus, e.g. a required exchange of the oil filter can be scheduled in a planned maintenance period. In the "Predictive Maintenance" concept, built-in sensors continuously monitor the system status. If these sensors are IO-Link-capable, the recorded data can be...
