Compatible with Swiss-style and fixed headstock lathes, Express automatic bar feeds from LNS America, Inc. facilitate partial change-overs in as little as 2 minutes and complete change-overs in 8 minutes. The quick change-overs are made possible through automatic adjustments built into the machines, says the company. Operators input values through the control keypad.
According to the company, the hydrostatic bearing design precisely supports barstock to allow the lathe to operate at high rpm without sacrificing accuracy. In addition, the Swiss machine connection tube supports material in the critical gap as the machine spindle moves forward.
Intelligent Synchronization monitors sliding headstock and bar feeding movements to anticipate headstock motion and synchronize the movements of the pusher and lathe headstock. A 3-S synchronization option is available for special applications such as running bar diameters smaller than 3 mm or for materials such as titanium, platinum and other challenging alloys.
