Multispindle CNC Lathe Features 27 NC Axes

The Index MS16 Plus includes six CNC spindles for parts up to 22 mm dia., accomplishing turning, drilling, milling, tapping, deep-hole drilling, and slotting in each of its six spindle positions.

Workpieces are automatically indexed through the six positions, receiving two or more operations at each position.

The 27 NC axes of the lathe include five NC grooving or boring slides, five NC cross-slides, one NC cutoff and/or back-boring slide, six work spindles, and one NC synchronous spindle, drum indexing. An additional five free NC axes of possible CNC auxiliary equipment are controlled by the company’s C200-4D CNC system.

Each of the six spindle positions can include a grooving or boring slide with one NC axis and a cross-slide with two NC axes (X and Z) that are arranged around each work spindle in a V shape, allowing use of several tools simultaneously on each work spindle.

The NC synchronous spindle for gripping the workpiece and an NC cutoff and back-boring slide enable production of turned parts with simple to medium complexity and up to about 70 mm in length.

The speed of each spindle can be controlled separately. Spindle speeds can be varied during cutting for each spindle position and each cutting edge of the tool. Speed changes and positioning of the spindles are possible even during spindle drum indexing, avoiding secondary processing times. The spindles offer maximum surface quality, short production times per piece, and extended tool life, the company states.

For end machining, the machine is equipped with a synchronous spindle driven by a hollow-shaft motor, allowing speeds up to 10,000 RPM. It can move 140 mm in Z at 30 m/min. to engage several rear end machining tools on the NC cutoff slide with the X and Z axis in succession more quickly. To achieve the shortest cycle times possible, the synchronous spindle accelerates to its maximum of 10,000 RPM in less than 0.7 seconds.
