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 threads ranging from 4-112 TPI as well as 23 metric threads, giving machinists broad threading versatility in a single machine. How does the backlash elimination on the compound and cross slide benefit machining accuracy? The compound and cross slide backlash elimination feature reduces unwanted play in the feed mechanism, allowing for more precise and repeatable cuts - a critical advantage when working to tight tolerances. Can this lathe perform taper turning? Yes. In addition to the included taper attachment, the tailstock may be offset for turning taper, providing two methods for producing tapered workpieces depending on the application and required taper length. What safety features are built into this lathe? This lathe includes a safety on/off switch, an emergency stop within easy reach of the operator, and a patented Electronic Chuck Key Docking Station that prevents startup without the chuck key when safely docked, helping to reduce the risk of accidents during operation.
