The L12-VII: Handling All Small-diameter Work with 7-axis Control
Detachable Guide Bushing and 15,000 min-1 High-speed spindle.
Machining using a guide bushing is a useful method for long, slender work-pieces. On the other hand, using a interchangeable guide bushing with short work-pieces leaves a long remnant bar, increasing material costs. The optimum machine configuration differs according to the work-piece to be machined, and up until now a variety of different machines have been required. The L12 solves this problem.
It is a simple matter to fit or remove the interchangeable guide bushing, so the machine configuration can be changed to suit the work-piece to be machined. As an automatic lathe that encompasses two roles in a single unit, it can be used to machine both long and short work pieces effectively. It also shows uncompromising performance as a machine for high-speed, small-diameter applications.
It shortens cycle times with a front spindle capable of high-speed rotation of 15,000 min-1 and 10,000 min-1 rotary tools. The L series that has built Cincom’s history is now creating the new ‘standard’ in automatic lathes for function and performance.
