This combination makes it a capable machine for precision turning, facing, threading, and taper work across a wide range of metalworking applications. The integrated DRO provides real-time axis position feedback, reducing setup time and improving repeatability on production and job-shop work. At 5,925 pounds, this is a full-size floor machine intended for professional installation in a machine shop environment. It is sold as a complete unit including the lathe, DRO system, taper attachment, and collet closer assembly.\u003c\/p\u003e\n\u003cp\u003eThe GH-1660ZX platform is a 16-inch swing, 60-inch between-centers engine lathe suited for industrial and commercial machine shops, toolrooms, and maintenance facilities. It handles general-purpose turning as well as precision work requiring taper cuts or collet-held workpieces. The collet closer expands workholding flexibility for bar stock and smaller diameter parts, while the taper attachment enables accurate taper turning without offsetting the tailstock. This configuration is appropriate for facilities running production runs or custom one-off machining where accuracy and repeatability are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e300S digital readout (DRO) system provides real-time axis position display for improved accuracy and faster setups\u003c\/li\u003e\n  \u003cli\u003eTaper attachment enables precise taper turning without tailstock offset, preserving center alignment\u003c\/li\u003e\n  \u003cli\u003eCollet closer expands workholding options for bar stock and small-diameter parts\u003c\/li\u003e\n  \u003cli\u003eGH-1660ZX gap-bed design accommodates larger-diameter workpieces when the gap section is removed\u003c\/li\u003e\n  \u003cli\u003eFull-size floor machine built for continuous industrial use in professional machine shop environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a complete OEM-configured unit for the JET GH-1660ZX engine lathe platform.

The machine must be leveled on a reinforced concrete floor using precision leveling pads or mounts prior to operation. Electrical connection should be performed by a licensed electrician in accordance with NEC requirements for the specified voltage and phase. Confirm all guards, covers, and safety interlocks are properly installed and functional before initial power-on.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5925 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JET\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 321391\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JET","offers":[{"title":"Default Title","offer_id":51345813406002,"sku":"321391","price":53966.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310500314.jpg?v=1782063702","url":"https:\/\/voomisupply.com\/products\/jet-321391-lathe-300s-dro-taper-attachment-collet-closer","provider":"Voomi Supply","version":"1.0","type":"link"}
