Jet ETM-949 Mill 3-Axis ACURITE 303 (Quill) DRO Servo X Pwrfd (894206)

Description

The Jet ETM-949 Mill 3-Axis ACURITE 303 (Quill) DRO Servo X Pwrfd (894206) is a professional-grade milling machine designed to meet the rigorous demands of modern machining. As part of Jet’s Elite series, this mill embodies a commitment to precision, reliability, and durability.

KEY FEATURES AND BENEFITS:

• Precision Engineering: At the heart of this mill is a high-precision spindle assembly, featuring class 7210 (P4, ABEC-7) precision angular bearings, delivering an industry-leading spindle taper runout of 0.00012″. The Chromium Molybdenum spindle is fully hardened and ground to maintain strict tolerances, ensuring consistent accuracy in your work. The seamless, one-piece steel quill is also induction hardened and chromed for added strength and precision.
• Hand-Scraped Ways and Enhanced Control: The Y and Z-axis ways are meticulously hand-scraped to a minimum of 16 points per square inch, resulting in superior oil retention and exceptionally smooth movements. Table and saddle backlash is minimized by an advanced double nut design, eliminating end-play for precise lateral movements.
• Durable Construction and Performance: Built to last, this mill features a patented vari-disc key that offers ten times the wear resistance of aluminum or brass keys. Variable speed pulleys are ground and dynamically balanced, reducing vibration and ensuring smooth speed transitions. A ball bearing-supported motor shaft ensures quiet and accurate operation at any speed.
• Automation and Safety: The ETM-949 comes equipped with a 3-Axis ACU-RITE 303 DRO (Digital Readout), providing precise measurements on three axes for enhanced accuracy. A servo motor controls the X-axis movement, offering smooth and precise operation. The mill also features automatic lubrication every 30 minutes, ensuring consistent performance and longevity. Safety features include a spindle safety guard, electronic spindle brake, and CSA Group certification.
