JET EVS-949 Mill with 3-Axis ACU-RITE 303 (Knee) DRO, Servo X Y Z-Axis Powerfeeds & Air Powered Draw Bar is a heavy-duty, variable speed vertical milling machine engineered for machinists and production shops demanding exceptional precision, versatility, and reliability. Driven by a 3 HP, 230V, 3-Phase motor and offering a spindle speed range of 60-5,000 RPM, this USA-made machine integrates an ACU-RITE 303 3-Axis Knee DRO, servo-powered X, Y, and Z-axis powerfeeds, and an air-powered draw bar into a single, fully equipped milling solution built to meet strict tolerance requirements.

Key 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

Frequently Asked Questions

What spindle speed range does this mill provide?

This mill offers a variable spindle speed range of 60-5,000 RPM, made possible through variable speed pulleys that are ground and multiplane dynamically balanced to reduce vibration and ensure smooth speed transitions across the entire range.

What is the table size and how much travel does it have?

The table measures 9 x 49 in. and provides 36 in. of longitudinal travel and 12 in. of cross travel. The knee offers 16 in. of travel and the ram provides 14 in. of travel, giving operators a wide working envelope for diverse milling operations.

How does this mill control backlash for precise movements?

The table and saddle backlash is controlled by an advanced double nut design that eliminates end-play for precisely controlled lateral movements. Additionally, heat treated and polished lead screws are supported by thrust bearings ensuring smooth, incremental movements of the table under load.

What motor and power requirements does this mill have?

This mill is powered by a 3 HP, 230V, 3-Phase motor with an amperage draw of 18 amps at 230V 3Ph. It is designed for three-phase shop environments and comes fully equipped with servo X, Y, and Z-axis powerfeeds as well as an air-powered draw bar for efficient tool changes.
