TSS-C series

Shibaura machine’s TSS-C series machines, which have a high reputation for performance and versatility are now available with additional features

Main features

Main features TSS-C(S) model was developed with the addition of a live spindle and table indexing to the CNC vertical boring and turning machine of single column type

TSS-C(S) model also performs machining operations as boring, drilling and tapping

Table diameter/maximum swing assures stable machining even of large-diameter workpieces

TSS-C series preserves the best features of single-column machine. The stationary column and the moving table perform stable and accurate machining of large-diameter workpieces, larger the table diameter

Two super-precision roller bearings of table maintain excellent stability

The table supported by two roller bearings stabilizes heavy-duty machining operations at high speed even at machining of large-diameter work

Highly rigid roller type linear guides

Roller type linear guides are employed for the rail head guideway (X-axis) to assure smooth high-speed feed and micro feed. The positioning accuracy has also increased

Powerful, accurate and easy-to-operate.

Table

The table is suppoeted by a super-precision thrust cylindrical roller bearing and a tapered roller bearing, it maintains stable heavy-duty cutting operations at high speed even at machining of large-diameter helical gear under the table through a V belt and speed change gear train.Table speed change is performed by a two-range hydraulic shift and AC motor control.

Column and arm

The thick-walled, well-ribbed and box-shaped column has a wide sectional area to assure high rigidity and supports the arm by three guideways, The arm, integrated with the rear angle support, transmits cutting reaction force exerted on the rail head to the column with high efficiency.

Closed type rail head

The maximum cutting force of the ram is more than twice that of our conventional machines even when the ram is extended to its maximum stroke. The maximum output of live spindle is 18.5kW(25HP). The closed type single-block constructed rail head enclosing a 250mm(9.84in) square ram and other main machine components made of high-grade cast iron all assure high rigidity and quality machining.

Compensation device for straightness of rail head (patent pending)

When incorporated in the machine, the compensation device for straightness of rail head travel(option) autommatically compensates arm deflection according to the rail head movement, Thus, more accurate working accuracies can be assured.

Machine Specifications

CNC system for enhanced productivity

CNC FANUC Series31iA

An updated high-performance CNC FANUC Series 31iA is used as the NC system. In addition to the existing operating functions, the FANUC 31iA is complete with such display functions as help function, alarm/operation status display and servo/spindle waveform display(10.4″ color LCD spec). Operability has also improved

Manual operation

In addition to the CNC operation, the TSS-C machines can easily be operated manually, as required, through the pendant box which contains the necessary pushbuttons and other control switshes such as table forwaed/reverse, X-and Z-axis feed selector switches, table speed overeide switch, feedrate switch, feedrate override switch, operation mode selector switch and manual pulse generator(MPG). Just as in the conventional machines, efficient manual operations are possible, while observing the tool edge.
