Description VRTG40
VRTG40 — Rotary Unit for Gantry Systems: Industrial Reliability and Precision
Applications
The VRTG40 is a rotary unit designed for gantry (truss) systems performing automatic loading and unloading of CNC machines. Combined with pneumatic grippers (FR57 or FZ70), it forms a complete handling unit for disc-type and cylindrical workpieces. It is widely used in metalworking, mechanical engineering, and production lines where rapid part reorientation without stopping the cycle is required.
Why engineers choose the VRTG40
-
Smart housing design. A hierarchical, porous structure simplifies routing of sensor cables and pneumatic lines — reducing installation time and simplifying maintenance.
-
Fully internal air routing. All pneumatic channels run inside the housing, eliminating the risk of tangled, chafed, or damaged external hoses during intensive gantry operation.
-
M20 hydraulic buffer as standard. An industrial-grade shock absorber dampens impact loads when rotating heavy workpieces, protecting the unit, the gripper, and the part itself.
-
Compatibility with compensation modules. The VRTG40 can be supplemented with the VCHT-ZG40 module, which compensates for misalignment between gripper and workpiece — critical when handling castings and stampings.
-
Flexible configuration. Available with two-finger (VGFR57) or three-finger (VGFZ70) grippers, allowing a single rotary unit to handle different part types.
Application scenarios
-
Turning operations. 180° workpiece rotation for second-side machining without re-fixturing.
-
Machining centres. Part reorientation between operations within a single cycle.
-
Automated lines. Feeding disc-type blanks from a magazine into the machining zone with rotation to the required plane.
-
Robotic cells. Integration with an industrial robot for handling round parts.
To accurately select the VRTG40 rotary unit for your application, please provide the weight and dimensions of the workpiece, the required rotation angle, the gripper type and configuration, the need for a compensation module, and the operating conditions.Our specialists will assist you with the configuration and, if necessary, design custom adapter flanges for your gantry system. -
