CNC mill-turn centre has bigger bar
capacity
Modular CNC mill-turn centre that takes two to four tooling turrets and can cut with four tools simultaneously can now be specified for 80mm bar capacity.
The Turn Mill Center TNX80/65 with its up to four tool carriers already set new standards for high-performance machining last year A unique feature of this machine is the modular design of the two turrets - and even three or four turrets are possible

Pick-up spindle lathe has hexapod features
A new, hanging-spindle, vertical turning lathe (VTL) has been introduced by Index on which the spindle head is able to move freely in three dimensional space.
Thus each tool carrier can have its own Y-axis.
This, in turn, permits that up to four tools work completely autonomously without interfering with each other.
And this means that the TNX80/65 can achieve almost the same cycle times that have so far only been possible with multi spindle machines.
A profitable advantage is the possibility that the tool carriers can be freely assigned to the two spindles.
At the EMO 2005, the TNX80/65 was presented for the first time with an increased bar capacity from 65 mm to 80 mm.
This also means an extension of the performance parameters.
Another unique feature is the new vertical tool carrier.
This is an upright 4-side turret with a 360 deg B-axis.
There are two tool holders on each side.
While four holders are designed as milling spindles with a torque of up to 74Nm, the focus of the other stations is on high speeds of 6000 rev/min.
Of course, it is also possible to operate the counter spindle with the vertical turret.
The TNX80/65 is a highly complex turn mill center - this is also demonstrated by the powerful tool drives at the turrets with VDI40 tool holders.
For reasons of productivity, Traub has deliberately decided to do without a tool changer.
All tools are already available in the working area, which reduces the idle times to a considerable extent.
In summary, the cycle times can e g, be reduced by up to 3 minutes with an equipment of 55 tools and a chip-to-chip time of 1.2s from cutter to cutter can be reached - even in the most unfavorable case.
Milling with a torque of up to 74Nm - up to now, these values have only been achieved with milling or machining centers.
Another advantage is the possibility of 6-side machining even in angular positions.
The features of the TNX80/65 at one glance: * Extended range of workpieces because of an increased bar capacity from 65mm to 80mm.
* Modular design of the two turrets, optionally three or even four turrets possible.
* Each tool carrier can have its own Y-axis.
* Upright four-side turret with a 360 deg B-axis, on each side two tool holders, i e, a total of 8 tool holders.
