Prop 65: Cancer and Reproductive Harm Country of Origin: China Frequently Asked Questions Does this lathe support both inch and metric threading? Yes. Inch-metric dials are standard, and the lathe offers 40 inch thread options spanning 4-112 TPI as well as 23 metric thread options, making it highly versatile for both measurement systems. What safety features are included on this lathe? The lathe includes a safety on/off switch with an emergency stop within easy reach of the operator, a spindle jog button for safe gear engagement and spindle inching, and a patented Electronic Chuck Key Docking Station that prevents the machine from starting up unless the chuck key is safely docked. Can this lathe cut tapers? Yes. The tailstock may be offset for turning taper, and the machine also comes equipped with a taper attachment, providing two methods for producing tapered workpieces. How does backlash elimination on the compound and cross slide benefit precision work? Backlash elimination on both the compound and cross slide minimizes unwanted play in the feed mechanisms, resulting in more accurate and repeatable cuts - especially important when making fine finishing passes or holding tight dimensional tolerances.
