Note: Proper precautions should be taken such that the actuator doesn't receive any rotational torques or lateral loading. This may be accomplished by mounting a bearing at the end of the rod and by properly centering the work piece.
In a NC (numerically controlled) lathe, a hydraulic cylinder is used to push the cylindrical center work piece into the chuck from the opposite side. The following problems may occur when using the hydraulic cylinder:
1) When the work piece changes, this causes time-consuming setup changes
- Workers must manually position the work piece and use an indicator to make sure it is properly centered.
2) The pressure change is not subtle
- The pushing force for the work piece can be too strong and can cause it to bend
- In order to change the force, a reducing valve must be installed to change the pressure which is done by using a bypass circuit
However, by adopting the ROBO Cylinder, the setup is automated and thus makes the adjustment of the pushing force to the work piece easier.
