Jet ETM-949 Mill 3-Axis ACU-RITE 303 (Knee) DRO Servo X Pwrfd (894212)

Description

The Jet ETM-949 Mill 3-Axis ACU-RITE 303 (Knee) DRO Servo X Pwrfd (894212) is a professional-grade milling machine designed for machinists who demand precision, durability, and versatility. As part of Jet’s Elite series, this mill is packed with features that set it apart from the competition.

KEY FEATURES AND BENEFITS:

• Precision Engineering: At the heart of the ETM-949 is a precision-engineered spindle assembly designed to meet the most stringent tolerance requirements. The spindle utilizes class 7210 (P4, ABEC-7) precision angular bearings, resulting in an industry-leading spindle taper runout of 0.00012″. The Chromium Molybdenum spindle is fully hardened and ground for exceptional accuracy, while the one-piece steel quill is induction hardened and chromed for increased strength.
• The Y and Z-axis ways are hand-scraped to a minimum of 16 points per square inch, ensuring smooth movement and optimal lubrication. Heat-treated lead screws with thrust bearings deliver smooth, precise table movements under load. Additionally, the advanced double nut design eliminates backlash for tightly controlled lateral movements.
• Built to Last: The ETM-949 is built with longevity in mind. Certified Meehanite castings ensure the machine retains its rigidity and tolerances over years of use. A patented vari-disc key offers up to 10x the wear resistance of traditional keys, and the hardened and ground table provides a stable platform for working with various materials. The mill also features automatic lubrication every 30 minutes for consistent performance.
• Safety First: Operator safety is a priority with the ETM-949. The mill includes a spindle safety guard, an electronic spindle brake that prevents accidental start-ups, and a mounted control box with an emergency stop button. Additionally, the mill is CSA/CUS certified, meeting strict safety and electrical standards.
• Additional Features:
  • 3-Axis ACU-RITE 303 DRO for precise measurements
  • Servo-driven X-axis for smooth and accurate movement
