COMPARE BIGLIA B446 WITH CMZ TTL
DISCOVER THE MAIN DIFFERENCES BETWEEN THESE BAR TURNING LATHES
Both Biglia B446 and CMZ TTL are machines designed for manufacturing the same type of parts, so it could be surmised that they are lathes that compete with each other. However, once we start analysing their technical performances, we find many differences.
CMZ’s TTL has 8 integrated motors, all of them completely oil-cooled, in order to drive the spindles, X and Y motors, and the driven tools. The Biglia B446 has belts in both spindles and in the X and Y movements of the lower turret.
In terms of performance, Biglia B446 lacks of an X3 axis. CMZ’s TTL allows X3 movements in the sub-spindle. This feature allows:
- To use 3 tools working simultaneously, each tool governed by a different program which is running on a different channel. Biglia B446 has 2 channels, so it can only run 2 programs, and lacks of X3 movement in the sub-spindle.
- To incorporate a tailstock attached to the sub-spindle. In the TTL, it is possible to machine between the spindle and the tailstock while the lower turret finishes the part in the sub-spindle. Biglia B446 doesn’t have this functionality.
- The X3 movement in the sub-spindle reduces significatively the interferences between turrets, as it shifts the lower turrets allowing the use of very long components and drills. The Biglia B446 model doesn’t allow this option.
