TTL SERIES

TURNING CENTRE FOR HIGH PRODUCTION

Precision turning companies work with very high volumes, tight lead times and very high precision. The high precision turning centre in the TTL Series is the largest machine in CMZ’s range of multi-turret machines. Especially indicated for machining complex parts, the TTL is a beltless turning centre with 8 integrated motors. Its motorised turret is oil cooled and the spindles reduce acceleration time by half. Movements in the X3 and Z3 axes permit unique functionalities:

Tailstock (optional), enabling machining between the main spindle and tailstock while machining continues as normal in the sub-spindle.
Work with 3 tools at a time (Superimposed machining).
Machine longer parts: the large X3 axis travel moves the sub-spindle body away from centre line to reduce interferences.

The TTL Series is undoubtedly the best option for anyone looking for a high performance turning centre with maximum precision.

BELTLESS TURNING CENTRE

8 INTEGRATED MOTORS

The TTL Series is part of CMZ's range of turning centres for high volume production. With 8 integral built-in motors , this lathe is characterised by its high levels of precision and reliability. The design improves the quality of surface finishes, and achieves faster acceleration, resulting in quicker cycle times.

14 kW, 42 Nm, 12000 rpm

FULLY OIL-COOLED DRIVEN TOOL TURRET

24-position hydraulically clamped turrets. In our TTL series of turning centres, clamping is achieved with large diameter curvic coupling crowns which provide great stability and accuracy. The turret in this turning centre has two motors. The first is used to index the disc on the turret (indexes 30º in 150 ms). The second is an integrated motor that delivers 14 kW 42 Nm and 12000 rpm to the driven tools. The entire turret is oil-cooled to enable continuous working at 12,000 rpm.

SYNCHRONOUS SPINDLES

REDUCE ACCELERATION AND DECELERATION TIME BY HALF

Discover all the features of this turning centre. These are some of the characteristics of the spindles on this high precision CNC lathe:

Equipped with synchronous motors with high power and torque (35.5 kW and 205 Nm). They reduce acceleration and deceleration time by half (TTL-52 accelerates to 5000 rpm in 1.3 seconds).
The rotor on the synchronous motor has permanent magnets. That means there is no passing current and the spindle axis remains cold.
Both the integrated synchronous motor and the bearings are oil-cooled and provide excellent thermal stability.
The bearings assembled in the spindle are roller bearings and they provide shock robustness and high vibration damping.

FUNCTIONALITIES

Discover the exclusive functionalities of this turning centre thanks to the movements on the X3 and Z3 axes

Simultaneous work with tailstock and sub-spindle

This turning centre has the option of adding a tailstock attached to the sub-spindle body. That arrangement enables machining between main spindle and tailstock while machining continues as normal in the sub-spindle, as shown in the photograph.

Superimposed machining with 3 tools simultaneously

The TTL turning centre has two turrets, but the CNC has 3 programming channels for executing 3 programs simultaneously, each of them with their own offsets. The sub-spindle (X3 and Z3 axes) can work in channel three of the CNC in a compound manner with both the upper and lower turret. That is to say, for Superimposed machining with three simultaneous tools, each tool can be placed in each turret (upper and lower).

MACHINE LONGER PARTS

The X3 travel of the sub-spindle body, away from centre line, reduces interferences

AUTOMATION

AUTOMATE SHORT AND LONG BATCHES

ROBOT GL 20 II

CMZ’s Gantry loader GL 20II offers infinite automation solutions. With this Gantry Loader you can automate short and long batch runs. Its conversational programming system makes both handling and programming very easy. In addition, in order to maximise autonomy time, we have a wide variety of workstockers with large parts storage.

Here you can see our turning centre in the TTL Series equipped with a gantry loader Incorporating a gantry loader in your turning centre provides operators with great autonomy because part unloading can be automated. Unloading the finished part from the sub-spindle with our gantry GL2011 system means the turrets can continue working on the main spindle (reducing cycle time) and the finished part can be stacked individually avoiding contact.
