Marposs enhanced its gaging solutions for grinding machines with electrical gage actuators. This electro-mechanical system provides better control of the process and reduces maintenance time and costs. The updated products encompass the E-Fenar measuring system, electro-mechanical slides, and grinding tool arms managed by the Marposs BLÚ single cable integrated control system.

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 faster and easier to install as they only require a single cable for connection. With hydraulic systems, components tend to deteriorate – hoses chafe, fittings come loose, and fluids and filters must 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 gaging 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 gage on a part as compared to a traditional actuator requiring a full stroke to clear before checking another feature. The flexibility and accuracy of the actuators enables intermediate positioning points, speed control, and acceleration to be pre-programmed for automated component checking while in the machine.

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