The JET EVS-949 Mill with 3-Axis Newall DP700 (Knee) DRO, X & Y-Axis JET Powerfeeds, and Air Draw Bar is a precision-engineered vertical milling machine from JET, designed to deliver smooth, accurate, and reliable performance across a diverse variety of milling applications. Combining a robust variable-speed drive system, advanced backlash elimination, and a comprehensive digital readout package, this mill is built for machinists who demand exacting results and long-term durability in demanding shop environments. Key Features Ball bearing support of the motor shaft ensures proper loading, support, and alignment for quiet, accurate operation at any speed Heat treated and polished lead screws are supported by thrust bearings ensuring smooth, incremental movements of the table under load Seamless, one-piece, steel quill is induction hardened and chromed for increased strength and precision ground for greater accuracy Stainless steel Y-Axis way cover provides extra years of protection over the standard sheet metal cover The mounted control box houses major mill functions as well as an emergency stop button The table and saddle backlash is controlled by an advanced double nut design that eliminates end-play for precisely controlled lateral movements Variable speed pulleys are ground and multiplane dynamically balanced, reducing vibration and ensuring smooth speed transitions Specifications MPN: JT9-894369 Stock Number: 894369 Country of Origin: Taiwan Motor: 3 HP, 230V, 3 Ph Amperage Draw @ 230V 3Ph: 18 Number of Axis: 3 (Knee) Collet Capacity: 1/8-7/8 in. Distance Spindle to Column (Max.): 21-2/5 in. Max Distance Spindle to Table: 18-3/4 in. DRO: Newall DP700, 3-Axis (Knee) Powerfeeds: X & Y-Axis JET Powerfeeds Draw Bar: Air Draw Bar Frequently Asked Questions What type of quill does the JET EVS-949 use, and why does it matter for precision work? The JET EVS-949 features a seamless, one-piece, steel quill that is induction hardened and chromed for increased strength, then precision ground for greater accuracy. This construction ensures the quill maintains tight tolerances and resists wear, which is critical for achieving consistent, repeatable results during milling operations. How does this mill control backlash in the table and saddle movements? Backlash in the table and saddle is controlled by an advanced double nut design that eliminates end-play, resulting in precisely controlled lateral movements. This design minimizes positioning error and is especially important when performing tight-tolerance work that requires accurate incremental table positioning. What is the benefit of the variable speed pulleys being dynamically balanced? The variable speed pulleys are ground and multiplane dynamically balanced, which significantly reduces vibration during operation. Reduced vibration leads to smoother speed transitions, improved surface finish quality on workpieces, and less wear on the machine's components over time. What motor and power configuration does the JET EVS-949 require? The JET EVS-949 is powered by a 3 HP motor running on 230V, 3-phase power, with an amperage draw of 18 amps at 230V 3Ph. This configuration provides ample power for demanding milling tasks while maintaining consistent spindle performance across the operating range.
