JET JTM-2 Mill with 3-Axis ACU-RITE 203 DRO (Quill) and X & Y-Axis Powerfeeds is a professional-grade vertical milling machine engineered by JET for demanding machining operations. Built on certified Meehanite castings and equipped with precision hardened and ground ways, this step pulley R-8 mill delivers the rigidity, accuracy, and control that serious machinists require. The addition of the ACU-RITE 203 3-axis DRO and dual-axis powerfeeds elevates productivity by enabling precise, repeatable positioning on the X, Y, and quill axes.

Key Features

• Certified Meehanite castings for exceptional rigidity and vibration damping
• Heavy duty splined motor drive for reliable, consistent power transmission
• Internal coolant tank built into base for use with coolant system (coolant pump not included)
• Large diameter quill is chromed for smooth, precise vertical travel
• One shot lubrication system simplifies maintenance and extends component life
• Precision bored and honed milling head for accurate, repeatable results
• Precision hardened and ground ways for smooth movement and long-term accuracy
• Spindle head is internally cooled to prevent seizing during extended operation
• Three stage power downfeed with automatic stop for controlled, hands-free quill feeding
• Tolerance test sheet included for out-of-the-box verification of machine accuracy
• ACU-RITE 203 DRO with 3-axis (quill) digital readout for precise positioning
• X and Y-axis powerfeeds for automated table movement and reduced operator fatigue

Frequently Asked Questions

What type of spindle taper does the JTM-2 use?

The JTM-2 uses an R-8 spindle taper, which accepts a collet capacity range of 1/8 to 7/8 inch. This is a widely used standard in vertical milling machines, making compatible tooling readily available.

Does this mill include a coolant pump?

No, a coolant pump is not included. However, the machine features an internal coolant tank built into the base that is designed for use with a coolant system, so the infrastructure is in place to add one separately.

What are the available quill down feed rates?

The three-stage power downfeed offers three selectable feed rates: .0015, .003, and .006 inches per revolution (IPR). An automatic stop feature allows the quill to halt at a preset depth for repeatable drilling and boring operations.

How many spindle speeds does the JTM-2 offer, and what is the speed range?

The JTM-2 step pulley configuration provides 8 spindle speeds with a range spanning from 80 to 2,720 RPM, giving operators the flexibility to match cutting speed to a wide variety of materials and tooling diameters.
