FAQ

1. Can the number of cylinders and cylinder dimensions be customized?

Yes. You can specify the number of cylinders that you would like and the dimensions, including stroke, with your order. However, the maximum tonnage that each cylinder can deliver will come down with the diameter of the cylinder. Also, to be effective, the travel during forming cycle should be at least 4″ (10 cm).

2. Isn’t using hydraulic cylinders messy due to hydraulic fluid leaks?

Once the system is installed with a die in the press and is operating, there is almost no noticeable leakage of hydraulic fluid. All hoses are connected using zero-leak flat-face quick-disconnect couplings. Pressure transducers are connected with leak-preventing fittings. The only circumstance under which small amounts of fluid may leak are during bleeding of the system at start-up, and in the unlikely event of replacing a servovalve.

3. Is the system reliable? What maintenance is required?

The entire system design has been conceived with reliability and easy maintenance in mind. The PC-104 based ruggedized digital controller runs a highly reliable real-time operating system (QNX) in combination with a standard Intel processor, along with extensively field-tested analog-to-digital (A/D) and digital-to-analog (D/A) converters. The servovalves are rated for the highest levels of failsafe operation in both industrial motion control and aerospace applications (endurance tested
to 500 million cycles, MIL-STD-810 shock and vibration standard), as are the sensors. Independent operation of each cylinder ensures that the chances of single-point system failure are minimal. A system debug screen in the software also provides a first-level troubleshooting tool.

The system requires little more than a standard hydraulic system maintenance, such as periodic filtration of hydraulic oil, and ensuring that there is a sufficient level of hydraulic fluid to operate the system.

4. Can the software environment be customized?

Yes. We would be happy to work with you to do so, and to enable you to interface the system with other standard applications to maximize efficiency.
