Combining modern electronics with historic lineage to produce precision toolroom lathes

The EVS (electronic variable speed) spindle speed of the TURN-NADO lathes allow for dialing in the perfect cutting speed. This makes it much easier to achieve exacting tolerances and superior finishes on any job.

The TURN-NADO EVS Lathes come in three different sizes: 18" x 60", 21" x 80", and 21" x 120".

There are four spindle speed ranges that can be selected with the speed range lever. The spindle speed dial fine tunes the exact speed within the selected range between 18-1800 RPM.

Spindle speed is displayed on the digital readout conveniently located on the control panel.

A factory-installed Fagor digital readout displays the positioning of the carriage and cross slide.

A micrometer stop is used to limit carriage travel for production runs or make final adjustments to the carriage position.

Both the carriage and cross slide have power feed capability when the carriage is engaged with the feed rod.

To further ensure a high degree of accuracy, these lathes are equipped with high-quality spindle bearings. The spindles are D1-8 camlock with an MT#7 taper and 3.15" bore. The tailstocks have an MT#5 taper and 6-1/2" of quill travel.

The headstocks feature quick-change gear levers and the carriages include an adjustable clutch that disables automatic carriage feed when it contacts the feed stop or in the event of a crash.

The headstocks are equipped with a pressurized oiling system that pre-lubricates the bearings and gears before the spindle starts. This guarantees that the headstocks are properly lubricated in all start-up conditions, including high-load/low-speed operations.

The bed of the lathe is constructed with Meehanite-processed castings that are hardened and precision-ground in the traditional three V-way prismatic design. This continues a tradition long used on South Bend lathes for accuracy, durability, and rigidity.

The lathe is equipped with a foot brake to quickly stop the spindle instead of allowing it to coast to a stop on its own. Pressing the foot brake while the spindle is ON also cuts power to the motor.

The removeable chip drawer catches swarf and metal chips during the machining process. It contains a screen that keeps the large chips from returning to the reservoir, preventing pump damage.

When the coolant pump switch is turned ON, the fluid is delivered through the nozzle attached to the carriage. The flow is controlled by the valve lever at the base of the nozzle.
