The new VM 360 ID/OC grinding machine from Peter Wolters of America Inc. was developed from the design of the proven VM 300 grinding machine. VM 360 operates with seven CNC axes, which can be optionally supplemented by another five CNC axes. For this reason the Peter Wolters continues its performance according to the requirements of their customers within the aircraft industry, the spindle industry as well as other mechanical engineering industries. In a single pass, the VM 360 grinds workpieces with a weight of up to 1300 lbs., a length of up to 52" and with an OD of up to 32" . One major feature is the stable and rigid turret-mounted grinding spindles for external grinding. It carries two grinding wheels; each with diameters of 16" or 20". The VM 360 can therefore be used as an external cylindrical grinding machine. For internal grinding, four separate high-speed grinding spindles are mounted on a second indexing turret.
