The EVS 50 electrical clamping system, part of Röhm’s e-Quipment line of clamping and gripping systems, activates power chucks on turning and grinding machines without hydraulics or pneumatics. The clamping system operates on a standard external servomotor with 1.0 kW of power and is compatible with several industry-standard CNCs. According to the company, the electric system helps reduce overall energy consumption by using energy only during the short duration of the clamp and release cycle, or when clamping force modifications are needed. The system is also said to increase accuracy through faster, more precisely controlled clamping regulated through machine tool controls. Clamping force can be adjusted during workpiece rotation enabling reduction of the tensile force and pressure of the clamp for finish turning operations with reduced risk of workpiece deformation.
