Alfing introduces light metal parts machining concept

Alfing's new AL-series multi-spindle 5-axis machining center concept is designed for machining complex, light metal parts in medium to high volumes. The AL 204 is the leading machine in the series, with four individually driven box spindles arranged for HSK 63 tooling and separate anti-friction ways.

According to Alfing, higher Z-axis accuracy is possible due to patented new individual spindle compensation packaging. In addition, the placement of the individual spindles (alternately guided from top and bottom) occupies only half the space required by a traditional 4-spindle machine.

The Alfing AL series provides a CNC controlled 5-axis process with an overall working range of 200mm x 450mm x 400mm in the X, Y, and Z axes respectively. A multi-axis swiveling trunnion system reduces workpiece changeover time to about 2.0 sec. The D- and A- axes of this swiveling trunnion bring workpieces into position. Optionally, the A-axes can be equipped with up to 4 B-axes each for machining parts complete in a single set-up. All rotating axes are equipped with torque drives, resulting in long term accuracy and elimination of excessive wear. The modular design of the AL series allows for several machine variations to be configured with similar components. The series includes versions of two, three, and four-spindle machining centers with individually driven box spindles as well as the standard models with fixed center heads and one drive in the z-axis.

All machine models can be equipped with either linear motors or ball screw drives. While the linear machines achieve speed rates of up to 180 m/min, and accelerations of up to 20 m/s², the maximum speed with conventional drive technology is at 90 m/min and 10 m/s² respectively.
