JET JVM-836-1 Mill with X-Axis Powerfeed is a professional-grade vertical milling machine from JET, engineered for machinists and manufacturing shops that demand repeatable accuracy, rigid construction, and versatile cutting performance. With a precision bored and honed milling head, a hardened and ground table, and a built-in X-Axis powerfeed, this step pulley R-8 mill delivers the consistency and control needed for demanding milling operations.

Key Features

• Precision bored and honed milling head - ensures tight tolerances and consistent material removal across a wide range of milling tasks
• Hardened and ground precision table - provides a durable, flat work surface that maintains accuracy over years of heavy use
• Precision ground dovetail ways - deliver smooth, accurate table travel with minimal play for reliable repeatability
• High precision spindle bearings - reduce runout and vibration, supporting cleaner cuts and longer tool life
• Large diameter quill is chromed - resists wear and corrosion while providing a smooth quill stroke throughout 5 inches of spindle travel
• One shot lubrication system - simplifies maintenance by delivering oil to all critical way surfaces with a single stroke
• Head tilts left or right - adds angular milling versatility without repositioning the workpiece
• Graduated scale on column - allows quick, accurate vertical positioning of the milling head
• X-Axis powerfeed - automates longitudinal table movement for consistent feed rates and reduced operator fatigue during long passes
• Locks on all moving surfaces increase operator safety during setup and cutting
• Backed by the JET Two-Year Warranty for industry-leading peace of mind

Frequently Asked Questions

What spindle taper and collet range does the JET JVM-836-1 use?

The JVM-836-1 uses an R-8 spindle taper and accepts collets ranging from 1/8 inch to 7/8 inch, making it compatible with a wide variety of standard R-8 tooling used in professional machine shops.

How does the X-Axis powerfeed benefit milling operations?

The X-Axis powerfeed automates longitudinal table movement, providing consistent feed rates during long cutting passes. This reduces operator fatigue, improves surface finish consistency, and helps maintain more uniform chip loads on cutting tools. Note that longitudinal travel with the powerfeed is 18 inches, compared to 22-1/4 inches for manual travel.

What is the quill travel and how many down feed rates are available?

The chromed large-diameter quill provides 5 inches of spindle travel. Three selectable quill down feed rates are available - .0015, .003, and .006 inches per revolution - allowing the operator to match the feed rate to the material and cutting tool requirements.

Does the head on the JVM-836-1 tilt, and what lubrication system does it use?

Yes, the milling head tilts both left and right, enabling angular milling operations without repositioning the workpiece. The machine also features a one shot lubrication system that delivers lubricant to all critical way surfaces with a single stroke, simplifying routine maintenance and helping extend the service life of precision ground dovetail ways and other moving components.
