KVR-GR
An example of special specification
[Application]
Suitable for grinding by vacuum chucking such nonmagnetic workpieces as aluminum alloy, copper alloy, stainless steel and plastics.

[Features]
  • Workpieces are vacuum chucked in the area defined by seal rubber strings set in the grid grooves, ensuring good sealing and consistent holding power.
  • A desired work area can be set by cutting the seal rubber string (φ6 × 5 - 20 m, included) according to workpieces.
  • The suction ports are provided in two places on all models to allow setting two workpieces.
  • A vacuum coupler to connect to the vacuum system is provided. (Vacuum is turned on and off with the valve on the vacuum system.)
  • Single stoppers are provided.
  • The main unit is made of iron to enable the chuck to be held by an existing magnetic chuck.

VACUUM SYSTEM [VPU-EG] CATALOG
Light weight and compact. Satisfactory functions !
VPU-EG
[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. (Vacuum adjustment, interlock with the machine via vacuum check output signals, etc.)
