S12 - The Efficient for the highest
tolerances The Studer S12
production cylindrical grinding machine with a distance between
centres of 150 mm, a height of centres of 175 mm and a grinding
wheel diameter of 500 mm has been targeted at 'Precision without
compromise'. At the heart of the machine are high precision
positionable linear motors and a completely new, patented drive /
guide system. The extremely rigid slides with hydrostatic bearings
are magnetically pre-tensioned and the in-feed movement can be
programmed in 10-nanometer steps.
Highly dynamic
axis drives with linear motor technology, short response times,
short travels and fast integrated loading systems make the S12 the
new standard for precision and productivity. This is further
helped by the high-speed grinding (HSG) option with
circumferential speeds of up to 140 m/sec.
