Vertical Mill with X Y Axis Powerfeeds for Metalworking
JET JTM-4VS Mill with X and Y-Axis Powerfeeds
The JET JTM-4VS Mill with X and Y-Axis Powerfeeds is a versatile variable-speed vertical milling machine designed for machine shops, fabrication facilities, maintenance departments, and experienced metalworkers. It combines the rigidity of a traditional knee mill with powered table movement on both the X and Y axes, helping improve consistency and reduce operator effort during longer machining operations.
At the heart of the machine is a 2 HP, 230 V, single-phase motor driving an R-8 spindle with a variable speed range of approximately 80–3,800 RPM. The machine features an 8 x 32-inch worktable, a tilting and swiveling milling head, and powerfeeds on both longitudinal and cross-table movements.
Key Features
2 HP motor — Provides ample power for general milling, drilling, boring, and facing operations.
Variable-speed spindle — Offers approximately 80–3,800 RPM for matching spindle speed to the cutter and material.
R-8 spindle taper — Compatible with a broad selection of milling tooling and accessories.
X- and Y-axis powerfeeds — Automate longitudinal and cross-table movement, reducing manual handwheel operation.
8 x 32-inch worktable — Provides a practical work surface for workpieces, vises, and fixtures.
Tilting and swiveling head — Allows angled milling and drilling operations.
Knee-type construction — Provides rigid support and substantial vertical adjustment.
Quill feed — Provides controlled spindle movement for drilling and boring.
Quill depth stop — Helps maintain repeatable drilling depths.
Spindle brake — Helps bring the spindle to a stop quickly after machining.
Chrome-plated quill — Provides a durable surface for repeated quill movement.
Way covers — Help protect critical slideways from chips and machining debris.
Adjustable table gibs — Help maintain proper slideway fit and minimize unwanted movement.
Heavy-duty floor-standing design — Provides a stable platform for demanding workshop applications.

X- and Y-Axis Powerfeeds
A major advantage of this JTM-4VS configuration is the addition of powerfeeds on both the X and Y axes.
The X-axis powerfeed automatically moves the table longitudinally, while the Y-axis powerfeed controls cross-table movement. This allows the operator to maintain a more consistent feed rate instead of manually turning the table handwheels throughout the cut.
Powerfeeds can be particularly useful when:
Making longer milling passes
Producing consistent surface finishes
Performing repetitive cuts
Facing larger workpieces
Reducing operator fatigue
Maintaining a controlled feed rate
The operator can still use manual table controls when appropriate, providing flexibility between powered and manual machining.
Variable-Speed R-8 Spindle
The JTM-4VS uses a variable-speed R-8 spindle with a range of approximately 80 to 3,800 RPM.
The variable-speed design allows spindle speed to be adjusted without the need to continually change belts or pulleys. This makes it easier to select an appropriate cutting speed for different cutter diameters and workpiece materials.
The R-8 taper also provides access to a wide selection of commonly available milling accessories.
2 HP Motor
The 2 HP single-phase motor provides the power required for general-purpose milling applications. It is suitable for operations such as face milling, end milling, slotting, drilling, and boring.
The 230 V configuration is commonly suited to workshop environments equipped with an appropriate single-phase supply.
8 x 32-Inch Worktable
The JTM-4VS is equipped with an 8 x 32-inch worktable. Its size provides sufficient space for mounting workholding equipment such as machine vises and fixtures while leaving room for positioning the workpiece.
The table offers approximately 15-1/2 inches of longitudinal travel and 12 inches of cross travel, providing useful positioning flexibility.
The knee supplies additional vertical movement, while the quill can be used for controlled spindle positioning during drilling and boring.
Tilting and Swiveling Milling Head
The milling head can be tilted and swiveled to support machining operations that require an angled spindle orientation.
This makes the machine suitable for:
Angular milling
Bevel cuts
Inclined surfaces
Angled drilling
Specialized slotting
Custom machining operations
For conventional milling, the head can be returned to its standard vertical position.
Quill Feed and Depth Control
The machine's quill provides approximately 5 inches of controlled spindle travel. This allows the operator to drill or bore without having to reposition the entire knee.
A quill depth stop also helps establish repeatable drilling depths, which is useful when machining multiple holes with matching dimensions.
Knee-Type Construction
The traditional knee-mill design supports the worktable on a rigid knee and column assembly. The knee can be raised or lowered to accommodate different workpiece heights and tooling configurations.
The rigid construction provides a stable platform for cutting while allowing the operator to position the workpiece accurately relative to the spindle.
Manual and Powered Table Movement
Although the JTM-4VS includes powerfeeds on both X and Y axes, the machine retains manual table controls. This provides the operator with flexibility when setting up a job, making small positioning adjustments, or performing operations where manual control is preferred.
The combination of powered and manual movement makes the machine suitable for both production-style repetitive work and one-off custom machining.
Recommended Applications
The JET JTM-4VS with X and Y-Axis Powerfeeds is suitable for:
General milling
Face milling
End milling
Slotting
Drilling
Boring
Keyway machining
Prototype work
Repair machining
Toolroom applications
Maintenance work
Small-batch production
Metal fabrication
Why Choose the JET JTM-4VS?
The JET JTM-4VS Mill with X and Y-Axis Powerfeeds is designed for users who want the versatility of a manual knee mill combined with powered table movement. Its 2 HP motor, 80–3,800 RPM variable-speed R-8 spindle, 8 x 32-inch table, tilting head, and X/Y powerfeeds make it a flexible solution for a wide range of machining tasks.
The dual powerfeeds are especially useful for operators who regularly perform long milling passes, repetitive cuts, or surface-finishing operations and want a more consistent feed rate with less manual effort.
For machine shops, fabrication facilities, maintenance departments, and serious metalworking workshops, the JTM-4VS provides a practical combination of machining flexibility, powered table control, and traditional knee-mill rigidity.
