Device dampens bar vibration in sliding
headstocks
When fitted to a long sliding head stroke lathe headstock, this device dampens vibrations during bar machining.
As always attentive to the specific requirements of individual customers, IEMCA has recently designed for Zannini a device that, when fitted to the headstock, dampens vibrations during bar machining operations on sliding headstock lathes This device is particularly suited to lathes with long headstock stroke and for small diameter and/or flexible bars, effectively eliminating the need to change the bar feeder guides while affording even greater rotation speeds

MASTER 880 MP bar feeder gives maximum flexibility
To complete the MASTER 880 project in the rack and bundle versions, IEMCA has unveiled its new MASTER 880 MP feeder (Single-rack).
The device comprises a pneumatic collet featuring two half-bushings with the diameter of the bar to be machined.
Changeover operations are quick and easy thanks to the two screw-in knobs.
When closed, the collet brings the half-bushings into contact, thus creating a closed channel with a diameter 0.5mm greater than that of the bar.
The device stays closed throughout forward movement, opening just before the transit of the bar pusher.
It stays closed even after the opening of the front bushing, which is normally fitted at the front section of bar feeders.
Opening and closing of the collet is pneumatically actuated.
Control is by signals already used for other bar feeder functions.
The application of the device must be studied by the IEMCA engineering department to assess equipping requirements for any other type of lathes.
