Designed for precision metal removal in production and toolroom environments, this machine combines variable-speed spindle control with real-time positional feedback through the ACU-RITE 200S display. The integrated X powerfeed automates table travel on the horizontal axis, reducing operator fatigue during repetitive cuts. At 2,240 pounds, the JTM-4VS is a full-size knee mill built for professional machinists and metalworking shops requiring accuracy and repeatability across a wide range of milling operations.\u003c\/p\u003e\u003cp\u003eThe JET 690221 is suited for job shops, tool-and-die operations, maintenance departments, and vocational training environments. The JTM-4VS platform is a standard vertical knee mill configuration used for face milling, end milling, boring, and drilling on ferrous and non-ferrous materials. The factory-installed DRO and powerfeed make this configuration ready for productive work immediately upon installation, without requiring additional field retrofitting of positioning or feed equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFactory-installed 3-axis ACU-RITE 200S DRO provides real-time X, Y, and quill position readout\u003c\/li\u003e\n\u003cli\u003eX-axis powerfeed installed at the factory for consistent, hands-free table travel\u003c\/li\u003e\n\u003cli\u003eVariable-speed (VS) spindle drive allows RPM adjustment without changing belts or gears\u003c\/li\u003e\n\u003cli\u003eFull-size knee mill construction at 2,240 pounds for rigidity and vibration damping during cuts\u003c\/li\u003e\n\u003cli\u003eQuill DRO integration supports precise depth-of-cut control on drilling and boring operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a complete, self-contained vertical knee mill unit in the JTM-4VS product line.

Electrical connection must be performed by a licensed electrician in accordance with applicable NEC requirements for the machine's voltage and phase configuration. Verify spindle alignment and table tramming before initial operation. Do not operate the machine until all shipping brackets and restraints have been removed per the manufacturer's installation documentation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2240 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDRO\u003c\/strong\u003e: ACU-RITE 200S 3-Axis (Quill)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePowerfeed\u003c\/strong\u003e: X-Axis, factory installed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle Drive\u003c\/strong\u003e: Variable Speed (VS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662755516405\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 690221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JET","offers":[{"title":"Default Title","offer_id":51345454301490,"sku":"690221","price":26886.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310501181.jpg?v=1782058710","url":"https:\/\/voomisupply.com\/products\/jet-690221-vertical-mill-3-axis-dro-x-powerfeed","provider":"Voomi Supply","version":"1.0","type":"link"}
