Jet ETM-949 Mill 3-Axis ACURITE 203 (Quill) DRO XYZ Powerfeed (894121)

Description

The Jet ETM-949 Mill 3-Axis ACURITE 203 (Quill) DRO XYZ Powerfeed (894121) is a testament to Jet’s commitment to precision, durability, and performance. Engineered to meet the rigorous demands of industrial settings, this mill offers a robust set of features designed to enhance accuracy, control, and longevity.

KEY FEATURES AND BENEFITS:

• Unparalleled Precision: At the heart of the ETM-949 is a high-precision spindle assembly, featuring class 7210 (P4, ABEC-7) angular bearings. This advanced design achieves an industry-leading spindle taper runout of 0.00012″, ensuring exceptional accuracy and smooth operation. The Chromium Molybdenum spindle is fully hardened and precision ground, further contributing to its exceptional performance.
• Engineered for Durability: Jet has gone the extra mile to ensure the ETM-949’s longevity. Hand-scraped Y and Z-axis ways (minimum 16 points per square inch) provide greater oil retention and smoother movements, minimizing wear and tear. Certified Meehanite® castings maintain their tolerances and rigidity, ensuring the mill remains accurate and reliable even after years of use.
• Enhanced Control and Safety: The ETM-949 is equipped with 3-axis ACU-RITE 203 DRO (Digital Read Out) and X, Y, Z-axis power feeds, providing operators with precise control over every movement. An advanced double nut design eliminates backlash for accurate lateral control, and heat-treated lead screws with thrust bearings ensure smooth, incremental table movements.
