Tornos completes the turning line-up 

Tornos’ entry-level offering comprises two product lines, namely the CT20 machine, the second version of the machine recently introduced, and the Swiss DT machine. Against this backdrop, the Swiss DT13 and Swiss DT26 models have undergone significant modifications that are aimed at improving their rigidity and axis feed rates. Moreover, the Tisis programming software has been enhanced to enable optimum performance and productivity.

CT 20: a rapid return on investment

The CT20 is a small, sturdy machine designed to be simple to use. It features five linear axes, two C-axes, and, in its basic configuration, is supplied with drive motors/driven tools for main and back machining operations.

Next to the counter-spindle, the machine can accommodate two driven tools for work in main operations and can be equipped with 11 driven tools, with a total of 27 tools across the two machining areas. Such flexibility is welcome in this machine class. Additionally, the machine can be optionally fitted with a thread-whirling cutter, a polygon cutter, a triple drilling/milling unit as well as a slotting device for back machining.

"Our CT 20 is the most affordable machine of the entire Tornos product line-up and has proved to be highly successful in the market," Philippe Charles, product manager at Tornos, explains. Thanks to its appealing price, it allows a rapid return on investment. Its modular tooling system and stable and rigid cast-iron frame make the machine an excellent partner for all situations.”

Swiss DT13: productivity

As its name suggests, the Swiss DT13 has been developed for 13mm maximum bar diameters or 10mm without bar preparation. It has five linear axes and two C-axes and features a kinematic system for high productivity applications.

Through impressive feed rates that can reach 35mm/minute and L-type kinematics, the Swiss DT13 is fast with short chip-to-chip times. In addition to 15,000rpm spindles, the machine is equipped with a motorised synchronous guide bush to improve machining accuracy and surface finish and save valuable seconds when machining long parts. For optimum flexibility, it can be converted to guide bush-less operation, and, optionally, provided with a modular position to accommodate a gear hobbing unit.

From a tooling perspective the DT13 is well-equipped. The machine can be equipped with 21 tools including seven driven tools. Three driven tools are located in the main gang tool post which can reach speeds up to 10,000rpm.

Swiss DT 26: powerful modular concept

The proven kinematics of the Swiss DT26 features five linear axes. Given the bar capacity and the performance of the machine, Tornos engineers have prioritised good chip removal by arranging the gang tool post above the guide bush and the spindle.

With spindles having more than 10.5kW of power for both main and counter operations machining and a bar capacity of 25.4mm, the Swiss DT26 enables large cutting depths. Against this backdrop, like the Swiss DT13, the machine is equipped with a motorised guide bush which can be removed if required in less than 15 minutes for collet operation.

The Swiss DT26 is supplied with four radial drills for front machining operations and can additionally be specified with a thread-whirling or polygon cutter. The former can be inclined by ±15°, has a maximum speed of 5,000rpm and can machine diameters up to 10mm.

The polygon cutter can also reach a maximum speed of 5,000rpm while the diameter of the polygon cutting tool is 80mm. The back machining positions can be equipped with both stationary tools and driven tools. These positions can also accommodate advanced tooling such as a high-frequency spindles specifically designed to machine Torx patterns or even a slotting device.

Standardised programming

Any Tornos machine can be programmed with Tisis programming software and this applies to the Swiss DT and CT20 machines. Additionally, they can be equipped with the Connectivity Pack that enables remote monitoring of the status of the machines.

Tisis has a database that contains the data of all tool carriers, from simple toolholder plates to polygon cutters, milling units and thread whirling cutters. Each of these devices has its own features that are taken into account by Tisis so, when a device is selected, only the positions that can accommodate will be enabled.

Furthermore, Tisis manages any incompatibilities between various devices and provides intuitive user guidance through the operation of the machine. Each tool carrier has its own illustration and therefore can be easily identified. It should also be noted that the standard geometries are automatically displayed as soon as a workpiece is selected.
