Now available from Marena Industries, Inc. is the Alpa line of precision surface grinders. Model RT 700/1000 and RTL 700/1000 are among the machines offered in the line. These machines include features such as hydrolift cross slide ways and externally-located hydraulic and electric components.
The wheelhead-traversing system is designed to promote rigidity in all positions. Ancillary equipment, such as wheel truing, profiling and forming devices to coolant swarf separators, vertical grinding attachments and magnetic chucks are also offered.
The RTL is equipped with the same features as the RT, but with a wider grinding width. An expanded table travel differentiates the 1000 series from the 700 series. While the RTL model is suited for production grinding of small parts, the RT model is useful for tool & die profile grinding, precision fitting and production grinding of small- to medium-sized parts.
