JET Elite EVS-949 Mill with 3-Axis ACU-RITE 303 (Quill) DRO - JT9-894337
Elite offers world class mills fully loaded with features, including certified Meehanite® castings, a Chromium Molybdenum spindle, and a hardened and ground table that provides a stable and accurate platform for milling. When working on the design of the mills we focused our efforts on the most accurate spindle assembly to meet strict tolerance requirements. This spindle utilizes class 7210 (P4, ABEC-7) precision angular bearings for an industry-leading spindle taper runout of 0.00012". To improve the reliability and durability we went back and did things the old fashioned way, we hand scraped the ways to a minimum of 16-point per inch. Every 30 minutes, your Elite mill is automatically lubricated with a flow of 3 to 6 cc/cy. For operator safety all Elite Mills are CSA/CUS Certified and all come with a spindle safety guard.
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
- Patented vari-disc key provides up to 10 times the wear resistance than aluminum or brass keys
- 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 electronic spindle brake, when activated, interrupts power to the spindle to prevent accidental start ups
- 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
