UK agent NL Machine Tool Consulting has announced that Tacchella Macchine will exhibit the latest model from the Elektra range of machines at Grindtec in Augsberg, Germany, on 17-20 March.

The new Tacchella Elektra range features CN control, an operator keyboard, 1,000mm and 1,500mm centre distances, 180mm and 230mm centre heights, 508mm-diameter external grinding wheels and several optional combinations of high-frequency internal grinding spindles.

The Elektra range has several executions and models.

The Elektra F range, for instance, features a fixed wheel head, measuring 508mm in diameter, and a grinding wheel mounted left (L configuration) for OD grinding.

The numerical control, which is of the new Fanuc 0iTD range, has a touch screen and the patented Touch-Tacchella software.

The Elektra U range features a manually swivelling wheel head accommodating up to two wheels for OD grinding, mounted left and right on a double-end wheel spindle with an integrated refrigerated motor.

Optionally, the wheel head can receive a high-frequency internal grinding spindle (LR/I configuration).

The numerical control is also of the new Fanuc 0iTD range, with a touch screen and the patented Touch-Tacchella software.

The Elektra UA range has the same basic characteristics as the U range but with the Tacchella patented B axis for automatically swivelling the wheel head – freely programmable via the CNC.

The numerical control is of the new Fanuc 310i A range, with an integrated intelligent terminal, a large 15in (38cm) LCD TFT screen and the latest patented Top-Tacchella software.

The operator control desk has been ergonomically redesigned, the control push buttons being equipped with light-emitting-diode backlight buttons; this is intended to facilitate machine control.

The CN panels in the F, U and UA ranges have been redesigned; the keyboard layout incorporates backlight keys.

Equipment layout on the new Elektra range has been enhanced to improve operator access to the workpiece area, with the efficient distribution of equipment in the work head and in the Tailstock area.

The Elektra Plus UA range features the same B axis and numerical control as the UA series and features wheel-head configurations in four different executions: one wheel mounted left and one wheel mounted right, on two wheel spindles.

Optionally, the wheel head can receive one high-frequency internal grinding spindle (L/I/R configuration); two wheels mounted left on two wheel spindles (L/L configuration); one wheel mounted right plus two high-frequency internal grinding spindles (R/I/I configuration); and four external grinding wheels on two double-end wheel spindles (LR/LR configuration).

All configurations feature integrated and refrigerated spindle motors.
