The recently introduced TTL Series from CMZ offers numerous possibilities to reduce cycle times. One of these functions is ‘superimpose’ machining.

With this function, the movement of the master channel (turret) is added to the slave channel (sub-spindle); in other words, it makes possible to machine two tool trajectories using the same turret station.
When the geometry of the part permits, it is possible to cut with four tools at the same time, performing a double-balance cutting process. One of the turrets and the sub-spindle (tool 1 + tool 2) will be programmed with the superimpose function, while the other turret will be programmed as a single trajectory (tool 3), and the second tool from this station (tool 4) will benefit from movement of the sub-spindle without the need to link an ISO code.
Four-tool simultaneous cutting is recommended for roughing processes in symmetrical parts. However, it should not be used in finishing operations as one of the tools is not controlled.
Programming a superimposed operation should not worry machine users, says CMZ, as several macros have been developed to ease calculation. Tool and work offsets will be transferred to the slave path before starting the combined machining movements. If users need assistance on how to program the TTL, the company’s Service Department can assist.
With CMZ’s ‘a star is born’ campaign, users can configure a TTL for themselves, and receive a made-to-measure offer using the company’s online calculator.
