The combination of tailstock centering that is free of play with an extremely large planar support, in conjunction with high clamping forces, enables BENZ Solidfix® to offer maximum tilt resistance and stability, which fulfills the requirements of milling. The high torque transfer and the high potential speeds also characterize the performance capability. This is supported by a special clamping mechanism, which operates centrally, without lateral forces, and works together with the high-precision and compact components to achieve top values for concentricity, flexural strength and repeatability. The design engineering makes the system suitable for tools with internal cooling.
