IEMCA automatic bar loader for multi-spindle autos
1 min read
IEMCA's Next 25 is compact, integrated loader for multi-spindle autos, accommodating 3 to 25 mm diameter round bars up to 3,100 mm long, as well as square and hexagon profiles up to 21 mm across flats.
Oil-filled guide channels hydrostatically support the bar as it rotates – eliminating vibration and enabling the production of high quality parts up to the feeder's maximum rated speed of 10,000 rpm.
Unlike other loaders, Next 25's innovative design allows each channel to accommodate variations of up to 6 mm in bar diameter, increasing equipment availability and minimising changeover downtime.
In operation, Next 25's brushless motor and worm screw drive initially locate the bar against the lathe's bar stop. Final raw material feeding is controlled by the machine tool, using either its feeding fingers or in-built bar pulling capabilities. Bar changes can be as fast as 6 secs, depending on the lathe's operating cycle, while IEMCA's proven snap-in system enables guide channel sets to be replaced in less than two minutes.
Next 25's 220 mm linear magazine capacity accommodates up to 20-off 11 mm diameter bars – or equivalent – with fully automatic stock selection. Changeovers to different sized raw material are both fast and simple. In addition, Next 25 incorporates a pair of sensors that alert the operator when the unit's magazine is empty or down to its last six bars.
