This is a heavy-duty manual turning machine designed for professional machine shops, tool rooms, and industrial production environments. The integrated DRO provides real-time axis position feedback, reducing setup time and improving repeatability on precision turning operations. The included collet closer expands workholding capability for bar stock and smaller-diameter parts. At 5,925 pounds, this is a full-size floor lathe intended for permanent or semi-permanent shop installation by qualified machinists or millwrights.\u003c\/p\u003e\n\u003cp\u003eThe GH-1660ZX configuration indicates a 16-inch swing over bed and 60-inch distance between centers, making it suited for medium-to-large diameter and medium-length workpieces. Typical applications include shaft turning, threading, boring, and facing operations on ferrous and non-ferrous materials. This machine is found in industrial maintenance facilities, job shops, vocational training centers, and precision manufacturing operations where a full-featured manual lathe with digital positioning is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e300S DRO system provides real-time axis position readout for repeatable setups\u003c\/li\u003e\n  \u003cli\u003eCollet closer included for efficient workholding on bar stock and small-diameter parts\u003c\/li\u003e\n  \u003cli\u003eGap bed design allows machining of larger-diameter workpieces when gap section is removed\u003c\/li\u003e\n  \u003cli\u003eHeavy cast iron construction at 5,925 pounds provides rigidity and vibration damping\u003c\/li\u003e\n  \u003cli\u003e16-inch swing and 60-inch between-centers capacity covers a wide range of turning work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe 321390 is the complete package assembly for the JET GH-1660ZX lathe platform with the 300S DRO and collet closer accessories factory-integrated.

The mounting surface must be a reinforced concrete floor capable of supporting the static and dynamic loads of a 5,925-pound machine. Electrical connection should be performed by a licensed electrician in accordance with applicable NEC requirements for the machine nameplate voltage and amperage. Level the machine on isolation pads or anchor bolts before operation and verify alignment of headstock and tailstock prior to first use.\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\u003eUnit of Measure\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: 321390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JET","offers":[{"title":"Default Title","offer_id":51343401222450,"sku":"321390","price":49163.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310500313.jpg?v=1782021209","url":"https:\/\/voomisupply.com\/products\/jet-321390-gap-bed-engine-lathe-with-dro-collet-closer","provider":"Voomi Supply","version":"1.0","type":"link"}
