Introducing CNC American Turnmaster Lathes
At Lagun Engineering we strive to continue our pursuit of excellence in CNC machining. For this reason, we’re extending our line of American Turnmasters to now include CNC versions of our most popular Tool Room Lathes.
LAGUN’S CNC AMERICAN TURNMASTER LATHES
With swings ranging from 14” to 18” these user-friendly tool room lathes guarantee extra rigidity and precision. This series incorporates all the standard features associated with our classic American Turnmaster series. Features such as their hardened and ground headstock and gears which enable smooth, quiet and vibration-free running.
Additionally, our CNC American Turnmaster Lathes come equipped with a heavy-duty headstock. These hearty headstocks come constructed using hardened and “Reischauer”-ground gears and shafts used to drive a forged alloy steel spindle. We’ve also included Republic Lagun’s signature 3-V-Way bed. This unique design eliminates twisting, and reversal error when turning long shaft O.D.’s.
ADVANTAGES OF CNC MACHINING
As we said in our previous post on 5-Axis machining, automation is leading the way. With this in mind, and as technology advances, we are dedicated to bringing our customers products that reflect this. By offering our classic American Turnmasters as CNC lathes our customers can expect more accurate results in less time than a traditional, manual lathe. Because of this when using the correct programming, you can repeatedly achieve the same results, making this an ideal machine for large-scale parts production.
