Handling All Small-diameter Work with 7-axis Control
The option to switch between Guide Bush Mode (Maximum speed of 15,000 min-1) and Non-Guide Bush mode (Maximum speed of 12,000 min-1) as standard.
Machining using a guide bushing is a useful method for long, slender work-pieces. On the other hand, using an interchangeable guide bushing with short workpieces 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 by reducing the length of bar remnant in Guide Bush Less Mode. The machine is capable of handling 16 mm diameter bar with an expansion kit.
Adoption of a modular tooling system
Addition of Y2 axis for even higher functionality
A modular tooling system has been adopted for the gang and back tool posts. The wide variety of tooling layouts available, such as “adjustable angle end-face spindle”, allows for angled hole drilling enhancing flexible machining. The addition of a Y2 axis to the back spindle strengthens back machining. This improves the degree of freedom for process allocation and increases the maximum number of tools that can be installed to 38.
Additionally, adoption of a built-in motor for the back spindle drive enables a maximum speed of 12,000 min-1. This reduces the acceleration/deceleration time to improve productivity. The machine is capable of handling 16 mm diameter bar with an expansion kit.
