ABSTRACT:
A cylindrical grinding machine comprising a slidable wheelhead assembly, a slide bed having ways supporting the wheelhead assembly, including means to prevent horizontal deviation of the wheelhead along the ways, and precision displacement means to slide the wheelhead assembly along the ways including, rotatable ball screw means axially secured to the slide bed, means to rotate the ball screw comprising a stepping motor, and nut housing means for coupling the nut means to the wheelhead assembly so that rotation of the ball screw slidably displaces the wheelhead assembly along the ways, the nut housing means including a medial flexible portion comprising two horizontal parallel plate portions having selectively configured transverse grooves so that vertical radial strain on the ball screw attributable to the wheelhead assembly is minimized.
