Accessories / Special Features
SIEMENS CNC Control, Model SINUMERIK 3 G for infeed of grinding head (Z),
table adjustment (X), dressing amount and speed (W, V) with all the
necessary cycles and programming possibilities. Manual Control unit for
correction of cutting parameters
CNC controlled automatic grinding process with input of feed amounts for
pre-grinding, fine grinding,finish grinding, spark-out and lift-off from
workpiece.
CNC controlled swivelling grinding wheel dressing device, built on below
the segmental head with automatic compensation. Dressing can be done
during the grinding process, i.e. the grinding head and rotary table stay
in place.
Automatic Swivelling of grinding head from cross grinding to radial
grinding,
Radial grinding = higher material removal. Cross grinding = more accurate
and flatness
Rotary magnetic chuck with ring pole division and stepless adjustment of
magnetic power.
Adjustable gap control (to avoid air grinding),
Separate switch and control cabinet with Amperemeter for Grinding Power
Large Coolant device with 2 Magnetic Separators and large intermediate
tank for approx.
3000 Ltrs. Coolant Liquid, Coolant Supply thru grinding spindle center,
Oil mist exhaust,

Condition : Good to very good. Machine can not be demonstrated under power
