The first prototype
of grinding machine, where linear motors are used instead of mechanical axis
movement in order to achieve maximum grinding accuracy even when grinding large
workpiece diameters. The basis of the system is Sinumerik 840Dsl, SINAMICS S120
inverters and SIMOTICS linear motors. The biggest challenge was the absolutely
precise positioning and adjustment of the linear motor in the Z-axis in the
length of 9 meters.
The biggest benefit
is the minimization of mechanical wear of the whole machine. Replacing the ball
screw with a linear motor is initially more costly but it will bring savings in
long-term operation. The machine maintains the highest possible machining
accuracy throughout its life without the need to replace mechanical parts.
