Key Features

• Automatic oiler releases 3 to 6 cc/cy of lubrication at adjustable time intervals, ensuring consistent lubrication with minimal operator intervention
• Class 7 spindle bearings support the spindle for maximum rigidity in heavy cutting applications
• Dual locks on all moveable surfaces provide secure, precise positioning during machining operations
• Spindle head is internally cooled, extending bearing, belt, and motor life for long-term reliability
• Swing away control box houses an e-stop and puts all controls at the operator's fingertips for convenient, safe operation
• Swing away safety shield for enhanced operator protection
• Table and ways are hardened up to 54 HRC and precision ground for greater accuracy
• The electrical box has been relocated to the back of the mill and houses two 115 outlets for powered accessories
• The innovative design of the machine base provides an easier solution to level the machine without raising it up off the floor
• The X-Axis and Y-Axis are coated with Turcite-B for reduced vibration and smooth movements
• Electronic Variable Speed (EVS) drive with Delta B inverter delivers a wide spindle speed range of 60-4,500 RPM
• Pneumatic power draw bar streamlines tool changes, reducing downtime and operator fatigue
• X-Axis and Y-Axis powerfeeds increase productivity and improve surface finish consistency
• 3-Axis Acu-Rite 203 DRO (Knee) provides precise, real-time position readout for all three axes

Frequently Asked Questions

What spindle speed range does this milling machine offer?

The JTM-1050EVS2/230 features an Electronic Variable Speed drive that delivers a continuous spindle speed range of 60-4,500 RPM, allowing operators to dial in the precise cutting speed required for a wide variety of materials and operations.

How does the automatic oiler work on this mill?

The automatic oiler releases 3 to 6 cc/cy of lubrication at adjustable time intervals, providing consistent lubrication to critical machine components without requiring constant manual attention from the operator.

What DRO system is included and how many axes does it cover?

This mill comes equipped with a 3-Axis Acu-Rite 203 DRO configured for the Knee, providing real-time digital position readout across all three axes to support precise, repeatable machining.

What type of power draw bar is included and what axis powerfeeds are provided?

The machine includes an air powered (pneumatic) draw bar for fast, effortless tool changes. Powerfeeds are provided on both the X-Axis and Y-Axis, reducing operator fatigue and improving feed consistency during extended machining runs.
