Knuth 37” RSM 800 Conventional Cylindrical Grinding Machine 370150

Description

The machine frames of the RSM series are characterized by a heavy design and long, supporting guideways. The table can be swiveled, and the finely adjustable hydraulic feed moves smoothly in the longitudinal direction. A large scale ring on the handwheel of the X-axis facilitates precise infeed, and the zero stop guarantees compliance with the desired dimension. The standard position indicator with linear scales is used to check the actual values. The headstock is rotated 180 degrees for internal grinding. An extensive accessory package is standard.
