It is constructed using the Meehanite casting process, which produces a dense, vibration-resistant machine base. The spindle head is precision bored and honed to maintain cutting accuracy. A three-stage power downfeed with automatic stop allows controlled drilling and boring cycles. This unit ships configured with a 3-axis ACU-RITE 200S digital readout, X and Y-axis powerfeeds, and a power draw bar, reducing manual tool-change effort. Licensed machinists and industrial maintenance techs are the primary installers and operators.\u003c\/p\u003e\u003cp\u003eThe JT9-690139 is suited for residential machine shops, manufacturing facilities, toolrooms, and vocational training centers requiring a full-featured knee mill. The ACU-RITE 200S DRO provides three-axis position readout for milling, drilling, and boring operations. X and Y-axis powerfeeds reduce operator fatigue during long surface cuts. The power draw bar speeds R8 toolholder changes. Available in single or three phase power configurations, this machine fits a range of shop electrical setups. An internal coolant tank is cast into the base for use with an optional coolant pump system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeehanite casting construction for a dense, vibration-dampening machine base and column\u003c\/li\u003e\n\u003cli\u003ePrecision bored and honed milling head with high-precision Class 7 spindle bearings\u003c\/li\u003e\n\u003cli\u003eThree-stage power downfeed with automatic stop for controlled depth cycles\u003c\/li\u003e\n\u003cli\u003e3-axis ACU-RITE 200S digital readout included for X, Y, and Z-axis position display\u003c\/li\u003e\n\u003cli\u003eX and Y-axis powerfeeds and power draw bar included as configured\u003c\/li\u003e\n\u003cli\u003ePrecision hardened and ground ways and table with adjustable gibs throughout\u003c\/li\u003e\n\u003cli\u003eInternal coolant tank cast into base; compatible with optional coolant pump system\u003c\/li\u003e\n\u003cli\u003eOne-shot lubrication system and way covers standard; tolerance test sheet included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-configured JTM-4VS series vertical knee milling machine. Tooling compatibility is based on the spindle taper specified for this series. Confirm spindle taper before ordering collets, end mill holders, or other toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified millwright or industrial machinery mechanic. Disconnect and lockout all electrical power before servicing the spindle, drive components, or electrical enclosure. The machine requires a level, rigid concrete or steel foundation adequate for a 2,420-pound load. Electrical connection must comply with applicable NEC requirements for the voltage and phase configuration selected; consult a licensed electrician for supply wiring.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMachine Series\u003c\/strong\u003e: JTM-4VS Variable Speed Vertical Knee Mill\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDRO\u003c\/strong\u003e: ACU-RITE 200S 3-Axis Digital Readout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePowerfeeds\u003c\/strong\u003e: X-Axis and Y-Axis\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Draw Bar\u003c\/strong\u003e: Included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 65.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 85 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2420 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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 EQUIPMENT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: JT9-690139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JET EQUIPMENT","offers":[{"title":"Default Title","offer_id":68102879019314,"sku":"JT9-690139","price":35182.04,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c79b0312686552321fbb262445dc2078.jpg?v=1793294024","url":"https:\/\/voomisupply.com\/products\/jet-equipment-jt9-690139-variable-speed-milling-machine","provider":"Voomi Supply","version":"1.0","type":"link"}
