        Product features
        ?The headstock is driven by ground gears , and the cyclic shifts changing by single handle to make the main spindle obtaining three ranges of high , medium and low speeds .  In the selected  range , the speed display will show the required cutting speed  by adjusting the speed knob. The speed range is with many choics ,especially suitable for low-speed tooling.
        ?Feeding box with 12 steps of variable speeds , covering common threading pitches .
        ?Longitudinal & cross auto feeding adopts inter-lock structure with good safety.
        ?Two V-type guideway with high accuracy and rigidity;
