VACUUM SYSTEM

［Application］
A vacuum system dedicated to the vacuum chucks. The shuck side is evacuated continuously
in order to eff ectively maintain atmospheric pressure on the workpiece on the chuck work face.
Note that this system must not be modifi ed to a pressure container.
［Features］
●A vacuum evacuation system, fi lter, vacuum tank and vacuum gage are incorporated neatly.
●Suction and evacuation operations to mount and demount workpieces can be done quickly
and easily with the attached special operating handle.
●A diff erence in pressure over 80 kPa (600 mmHg) can be obtained continuously.
■Ejector type VPU-E
A 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 be
used for both wet and dry machining operations. However, the use of a lubricator in the air line
must be avoided.
■Dry pump type VPU-D
A vacuum system to reduce pressure by evacuation by a pump driven by a motor. A power
source only is required to obtain an independent vacuum source. Note, however, this is
recommended only for dry machining operations.
■Other types
If 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 dry
operations and a water-sealed vacuum pump is required for wet operations depending on work
conditions. Please contact us.
