Zimmerman Presents New Milling Machine with Linear Drive
April 14, 2006
The new FZ 38 from Zimmerman is a CNC portal milling machine driven by linear motors.
According to the company's press release, the machine can achieve time/chip volumes up to 4,500 cm3/ min. Feed rates on linear axes of up to 60 m/min. and spindle speeds of up to 35,000 rpm make genuine HSC processing possible. Torque motors on rotational axes with feed rates of up to 150? per second are possible as well. With these feed rates, ancillary times for repositioning, tool orientation or tool change can be reduced.
The FZ 38 allows different work areas, milling spindles and control systems to be combined. The machine has permanent lateral walls, a clamping table connected to the foundation and an upper portal that moves in the x-direction and is driven on both sides. The workpiece is not moved.
The machine bed is constructed from gray cast steel, while the lateral walls, portal and z-slides are welded steel constructions. The lateral walls are filled with a special compound material for damping vibration and stabilizing temperature.
