JET JTM-1050EVS2/230 Mill with 3-Axis Acu-Rite 203 DRO (Quill) X, Y & Z-Axis Powerfeeds in Detail

The JET JTM-1050EVS2/230 mill represents a significant advancement in the realm of milling machines, offering both robust construction and cutting-edge features. Built using the Meehanite® casting process, this mill promises consistency, reliability, and durability. 

Build and Design

The JTM-1050EVS2/230 is constructed with a certified Meehanite® casting which is renowned for its excellent vibration dampening and robustness. The ribbed casting enhances rigidity and tolerance retention which is crucial for precision machining. Notably, the design of the column and base is newly revamped to ensure stability, facilitating easy leveling without the need to lift the machine, an advantage in heavy-duty operation settings.


This model is packed with several features aimed at improving usability, safety, and performance:

  • Swing Away Control Box: Places all necessary controls within easy reach of the operator, enhancing usability and safety with an integrated e-stop.
  • Automatic Oiler: Ensures consistent lubrication with adjustable intervals, vital for the longevity of moving parts.
  • Spindle Brake: Provides a heavy-duty mechanism to stop the spindle and cut power, adding an essential safety layer against accidental startups.
  • Cooling System: The internally cooled spindle head is a standout feature, prolonging the life of the spindle, belts, and motor by reducing heat buildup during intensive milling operations.
  • LED Work Lamp and Chip Pan: Enhances visibility and keeps the work area clean, reducing cleanup time and increasing focus on precision work.

Performance and Precision

The variable speed control of the spindle allows for a range from 60 to 4,500 RPM, accommodating various materials and cutting conditions. The Acu-Rite 200S DRO (Digital Read Out) enhances the machine’s precision, providing real-time feedback and positional accuracy to the operator. The powerfeeds on all three axes (X, Y, and Z) ensure smooth, consistent movements that are essential for fine milling work.

Ease of Use

One of the more innovative aspects of the JTM-1050EVS2/230 is its user-focused design. The Turcite-B coating on the X and Y axes minimizes vibration and facilitates smoother movements, which not only improves the machine’s feel but also its operational noise levels. The dual locks on all movable surfaces ensure that once settings are dialed in, they remain consistent without drift, crucial for batch production or long milling sessions.

Safety and Maintenance

JET has incorporated multiple safety features into this model, including a swing away safety shield and a robust spindle brake system. The machine also comes equipped with a CSA/CUS certification, affirming its compliance with North American safety standards. The automatic oiler and easy-access electrical box simplify maintenance, ensuring that the machine runs smoothly with minimal downtime.
