The specifications above correspond to JET JMD-45VSPFT, stock no. 351165. Some retailer listings report different shipping or assembled weights, so the manufacturer's/current product documentation should be used when exact handling or installation weight is critical.
Variable-Speed Geared Head
The machine's variable-speed geared head provides a broad spindle range of 50–2,500 RPM. This allows the operator to select a suitable speed for the workpiece material, cutter diameter, tooling, and type of operation.
The geared-head arrangement transfers power directly to the cutting tool while maintaining the rigidity expected from a heavier-duty mill/drill. Quick-select gear controls also make spindle-speed changes more convenient.
Newall DP500 2-Axis DRO
The integrated Newall DP500 2-axis digital readout provides digital position information for machine setup and operation. It gives the operator a convenient reference for monitoring movement along the machine's working axes.
The DRO is particularly useful when:
- Locating multiple holes
- Setting machining coordinates
- Repeating dimensions
- Monitoring table movement
- Performing multi-pass machining
- Setting up repetitive work
A DRO improves positional convenience, but proper workholding, measurement, tooling selection, and machine setup remain essential for accurate machining.
X-Axis Table Powerfeed
The X-axis powerfeed automatically moves the table along its longitudinal axis. Rather than manually turning the table handwheel throughout a milling pass, the operator can use powered movement to maintain a more consistent feed.
This is especially useful for:
- Longer milling passes
- Surface milling
- Slotting
- Repetitive machining
- Consistent feed-rate requirements
- Reducing operator fatigue
The table provides 20-1/2 inches of longitudinal travel, giving the powerfeed a substantial working range.
Power Downfeed
The JMD-45VSPFT also incorporates a power downfeed system. Total spindle travel is 5 inches, with 4-1/4 inches of automatic spindle travel available through the power downfeed.
This feature can make repetitive drilling operations easier by providing controlled, powered spindle movement. JET also specifies tapping capability for this machine configuration.
Milling and Drilling Capacity
The JMD-45VSPFT provides substantial capacity for a mill/drill:
- 1-1/2-inch drilling capacity
- 4-inch face-mill capacity
- 3/4-inch end-mill capacity
The R-8 spindle taper allows the use of a wide range of compatible milling accessories, making the machine adaptable to general drilling, face milling, end milling, slotting, and other metalworking operations.
Rigid Square-Column Construction
The machine uses a 7-7/8 x 7-5/8-inch square column with dovetail ways. This design provides a rigid support structure for the machine head and helps maintain stability during cutting.
The head can tilt 90° left and right, giving the operator additional flexibility when setting up angled machining operations. The machine also provides 19-11/16 inches of swing and up to 18-1/8 inches between the spindle and table.
Large Worktable
The 9-1/2 x 32-1/4-inch table provides useful space for workpieces, vises, clamps, and other fixtures. It offers 20-1/2 inches of longitudinal travel and 8-1/4 inches of cross travel.
The table's size and movement range make the machine suitable for a broad range of general-purpose machining tasks.
Practical Features
JET includes several features intended to make operation more convenient:
- Newall DP500 2-axis DRO
- X-axis table powerfeed
- Power downfeed
