Marposs has enhanced its gauging solutions for grinding machines with new electrical gauge actuators. As compared to former hydraulic and pneumatic solutions, this electro-mechanical system provides better control of the process as well as significantly reducing maintenance time and costs. The updated products encompass the E-Fenar measuring system, electro-mechanical slides and the grinding tool arms, which are managed by the Marposs Blú single cable integrated control system. 

As compared to traditional hydraulic or pneumatic devices, which can experience variations in pressure, the electromechanical solutions can run at higher rates given the ability to better control acceleration/deceleration and consistent speed rates. These electric solutions are also much faster and easier to install as they require only a single cable for connection. With hydraulic systems, which are constantly under high pressure and high flow rates, components tend to deteriorate; hoses chafe, fittings come loose and fluids and filters have to be changed regularly. An electric system eliminates all the piping, hoses, filters and much of the lubricant for ease of maintenance.

The E-Fenar in-process gauging solutions can be integrated into an orbital grinder for controlling size on different crankshaft parts or smooth eccentric shafts. Since positioning can be optimized through this control, several checks can be conducted by the same gauge on a part as compared to a traditional actuator requiring a full stroke to clear before going in to check another feature. The flexibility and accuracy of the actuators enables intermediate positioning points, speed control and acceleration to be pre-programmed for automated checking of the component while in the machine.

Linear E-Slides - available in 35, 50, 75, 100, 130, 170 and 200 mm strokes - enable reductions in cycle time, as well as flexibility, reliability and improved part quality through optimization of the grinding cycle.
