Fixed-Center Grinders

CF Series

This machine is particularly suitable for grinding in “through-feed”. It has a single-block cast iron base with a high number of reinforcing ribs aimed at minimizing vibrations. The slides have been designed to assure maximum performance in stock removal while eliminating any type of deflection. The workrest blade support if fixed onto the machine base simplifying the entire process of loading and unloading of the workpiece by having the entire systems fixed onto the ground. This type of arrangement drastically reduces change over time. The grinding wheel head equipped with a double support hydrodynamic spindle (Twin-grip) guarantees high rigidity and quality performance.

The control wheel spindle is sustained by bronze bushings immersed in oil, assuring high rigidity therefore eliminating any vibration that could otherwise cause workpiece shape errors during grinding operation.

The CNC axes of the “CF Series” grinding machines ensure complete autonomy on the management of the grinding processing. The software, entirely designed by SMT, offers a simple and intuitive interface which can also incorporate specific customizations requested by customer. Moreover, the inherited technologies built into the machine provide for excellent reliability and sturdiness and minimal maintenance requirement.
