Ch 7 GENERAL DESCRIPTION
GT 326-E
7.11 LATHE CONNECTING PARTS
Depending on the bar feed/machine configuration various mechanical parts could be mounted
between the bar feeder and the machine. Safety joint pipes for fixed headstock configurations,
Telescopic tube for sliding headstock machines, additional support, covers, etc. are part of this
mechanical interface. Please contact our office for further information.
Example:
The LNS Swiss safety connection eliminates the unsupported area between the bar feed and
machine tool to provide greater safety and better bar stock support. It consists of a telescoping
tube that extends in sections to maintain a continuous connection between the GT 326-E and the
machine sliding headstock. This feature allows the headstock to move forward to make parts
without the danger of exposed bar stock.
For added flexibility, the GT 326-E includes an assortment of reduction tubes to use within the
Swiss safety connection and the lathe headstock. The inside diameters of these reduction tubes
match those of the bar feed’s guide channels. They act as a combination spindle liner to reduce
the gap inside the spindle and additionally the inside diameter of the Swiss safety connection.
The result is reduced vibration and bar oscillation within a critical and traditionally
under-supported area. This GT 326-E feature improves part diameter tolerances, increases RPM,
enhances surface finish and extends tool life.
