JET Elite ETM-949 Mill with 3-Axis ACU-RITE 303 (Knee) DRO and X-Axis JET Powerfeed - JT9-894145
Elite offers world class mills fully loaded with features. With Certified Meehanite® castings, an electronic spindle brake that prevents accidental startups, and a hardened and ground table, this mill provides reliability and durability for milling a diverse variety of materials. Our patented vari-disc key provides up to 10 times the wear resistance than aluminum or brass keys. The fully hardened Chromium Molybdenum spindle meets strict tolerance requirements and utilizes class 7210 (P4, ABEC-7) precision angular bearings for the industry-leading spindle taper runout of 0.00012". The Y- and Z-axis ways are hand scraped to a minimum of 16 points per square inch for greater oil retention and smooth movements. Additionally, 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 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
- 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

Q&A
Q: What is the JET Elite ETM-949 Mill with ACU-RITE DRO and Powerfeed?
A: It’s a 9x49 Elite manual milling machine outfitted with a 3-axis ACU-RITE 303 knee-mounted DRO for precision measurement and a JET X-axis powerfeed for consistent table movement.
Q: Why consider this model?
A: The ACU-RITE 303 DRO gives accurate, easy-to-read positioning across all three axes, while the powered X-axis feed improves finish quality, reduces operator fatigue, and boosts efficiency.
Q: Who is this best for?
A: Machine shops, tool rooms, and manufacturing facilities needing reliable accuracy with some automation but not full multi-axis feeds.
Q: What makes it stand out?
A: Compared to the base ETM-949, this model offers 3-axis DRO precision plus automated X-axis control, balancing manual versatility with productivity upgrades.
Maintenance Tips
-
Clean table, ways, and leadscrews after each use; apply light oil to prevent rust.
-
Lubricate spindle, knee, and powerfeed drive per JET’s maintenance schedule.
-
Inspect DRO wiring and scales regularly for accuracy and protection from chips/dust.
-
Check gibs, backlash, and fasteners to maintain precise milling performance.
-
Monitor X-axis powerfeed; keep gears and housing well-oiled.
-
Drain, refill, or top off lubrication reservoirs as needed.
-
Keep machine level and store in a clean, dry environment for longevity.
