• Description
• The models of the RSM C series are precision cylindrical grinding machines designed for long and heavier workpieces. The series is suitable for processing individual parts as well as for small series production and offer additional flexibility with the internal grinding device. The classic design with a large machine bed, ground guides, and powerful drives for the work spindle, grinding spindle and hydraulic unit, make these machines a cost-effective solution for the precision grinding of larger workpieces.
• Features
• Large machine bed in a heavy design accommodates workpieces with lengths up to 79 inch and diameters up to 12 inch
• Wide, precision-ground guideways ensure maximum accuracy across the entire workpiece length and accommodate high workpiece weights
• The table features large dimensions and swivels in two directions – table movement via hand-wheel or automatically via linear hydraulic feed
• The robust feed valve allows very precise micro-feed control on the X-axis, including a user-adjustable dwell time at the end of the longitudinal table travel
• Hydraulic ratchet feed simplifies exact X-axis positioning, limited by an adjustable zero stop
• The grinding spindle features hydrostatic bearings and provides for maximum precision and surface quality, plus extraordinary tool life and rigidity
