The shuck side is evacuated continuouslyin order to effectively maintain atmospheric pressure on the workpiece on the chuck work face.Note that this system must not be modified to a pressure container.[Features]●A vacuum evacuation system, filter, vacuum tank and vacuum gage are incorporated neatly.●Suction and evacuation operations to mount and demount workpieces can be done quicklyand easily with the attached special operating handle.●A difference in pressure over 80 kPa (600 mmHg) can be obtained continuously.■Ejector type VPU-EA vacuum system to reduce pressure by jetting air at high pressure (principle of the spray gun).This is recommended where an air line by use of a compressor is installed. This type can beused for both wet and dry machining operations. However, the use of a lubricator in the air linemust be avoided.■Dry pump type VPU-DA vacuum system to reduce pressure by evacuation by a pump driven by a motor. A powersource only is required to obtain an independent vacuum source. Note, however, this isrecommended only for dry machining operations.■Other typesIf the physical contact with the bottom face of workpieces is poor, a large amount of air leaks,requiring a large evacuation amount. In such a case, a blower type is required for dryoperations and a water-sealed vacuum pump is required for wet operations depending on workconditions.

Satisfactory functions![Application]A vacuum system dedicated to the grid seal type vacuum chucks.[Features]●The vacuum tank has been eliminated to make a very compact size compared with the conventional model(VPU-E10). This system can be handled easily.●A function to check the vacuum status is incorporated.●This is for dry operation.●Auxiliary functions in consideration of operating status and safety are incorporated.
