Geared-Head Performance
The 6-speed geared head provides direct mechanical power transmission to the spindle. With a spindle-speed range of approximately 65 to 1,550 RPM, the machine offers a useful selection of speeds for different cutter sizes and workpiece materials.
Lower speeds are appropriate for larger tooling and heavier cuts, while higher speeds can be used with smaller cutters when the material and tooling permit.
The geared transmission is particularly useful when maintaining spindle torque is important during demanding drilling and milling operations.
Power Downfeed
The integrated power downfeed automatically moves the spindle during drilling and related operations. It can provide a more consistent feed than manually controlling the quill throughout the entire cut.
Power downfeed is useful for:
- Repetitive drilling
- Boring
- Counterboring
- Controlled-depth machining
- Production-oriented work
- Consistent hole-making
The machine also provides fine manual downfeed capability for applications where the operator needs more precise control over spindle movement.
Newall DP700 2-Axis DRO
The Newall DP700 2-axis digital readout provides digital position feedback for the machine's primary table axes.
This makes it easier to:
- Establish workpiece zero points.
- Locate multiple holes.
- Position slots and pockets.
- Repeat machining dimensions.
- Monitor table movement.
- Return to previously established positions.
The DRO is especially useful for multi-feature work where accurate positioning is more convenient with a digital display than by relying solely on graduated handwheel scales.
Square-Column Construction
The machine uses a rigid square column with dovetail ways to support the head and spindle assembly. This construction is intended to provide stability when the machine is subjected to the cutting forces produced during milling and drilling.
The rigid structure is well suited to:
- Face milling
- End milling
- Slotting
- Boring
- Drilling
- Counterboring
- General stock removal
Proper workholding and appropriate cutting parameters are still essential for achieving accurate results.
R8 Spindle
The R8 spindle taper is a widely used interface for milling machines. It gives the operator access to a broad range of compatible tooling and accessories.
Published capacities include:
- 1-1/2-inch drilling capacity
- 4-inch face-mill capacity
- 3/4-inch end-mill capacity
Actual capacity depends on the workpiece material, tooling, spindle speed, feed rate, depth of cut, and rigidity of the setup.
Tilting Head
The milling head tilts 90° to the left or right, allowing the spindle to be positioned for angled machining.
This feature can be useful for:
- Angled holes
- Beveled surfaces
- Angular milling
- Specialized fixtures
- Non-standard machining setups
The head should be properly secured and locked before beginning any cutting operation.
Worktable and Travel
A 9-1/2 x 32-1/4-inch table provides a substantial working surface for mounting workpieces, vises, clamps, and fixtures.
The table provides approximately:
- 20-1/2 inches of longitudinal travel
- 8-1/4 inches of cross travel
The table's 5/8-inch T-slots provide convenient attachment points for compatible workholding accessories.
For heavy or high-force operations, the workpiece should be secured with an appropriately sized vise or fixture.
Motor and Electrical Configuration
The machine is powered by a 1.5 HP single-phase motor with a 115/230V electrical configuration.
This configuration gives workshops flexibility when connecting the machine to an appropriate electrical supply. The voltage should be correctly configured before operation, and installation should follow JET's instructions and applicable electrical codes.
Typical Applications
The JET Geared Head Mill/Drill is suitable for:
- Professional machine shops
- Fabrication facilities
- Maintenance departments
- Equipment repair
- Tool rooms
- Prototype machining
- Small-batch production
- General metalworking
- Technical training environments
It is particularly useful where a conventional drill press lacks the rigidity, tooling flexibility, and table positioning capability needed for milling work.
Common Machining Operations
Drilling
Produce holes with appropriate drill tooling and controlled spindle feed.
Milling
Remove material from surfaces, edges, and workpiece features using compatible milling cutters.
Boring
Enlarge and finish existing holes with controlled tool movement.
Face Milling
Produce flat machined surfaces using a suitable face mill.
Slotting
Create channels and slots using appropriate end mills.
Counterboring
Produce stepped holes for fasteners and other components.
Angled Machining
Use the tilting head for appropriate angular operations.
Benefits for Professional Users
Digital Position Feedback
The Newall DP700 DRO makes X/Y positioning easier to monitor and repeat.
Geared-Head Drive
Six spindle speeds provide useful mechanical power for a wide range of drilling and milling applications.
Power Downfeed
Automatic spindle movement helps produce more consistent drilling and boring results.
Rigid Square Column
The column and dovetail ways provide a stable foundation for machining.
R8 Tooling Compatibility
The R8 spindle supports a broad selection of standard milling accessories.
Large Worktable
The 32-1/4-inch-long table provides useful working space for fixtures and larger workpieces.
Maintenance
Regular maintenance helps maintain machining accuracy and extend equipment life.
Inspect and maintain:
- Spindle and bearings
- Gear head
- Quill and power-downfeed mechanism
- Column and dovetail ways
- Table and T-slots
- Lead screws
- DRO scales and cables
- Electrical connections
- Lubrication points
Remove chips from the table and ways after machining. Keep the DRO scales clean and protected from metal chips, coolant, and other contaminants.
Follow the manufacturer's recommended lubrication and maintenance schedule.
Safety Considerations
Always wear appropriate eye protection when operating the machine and use additional PPE appropriate to the material and machining process.
Secure the workpiece firmly using a suitable vise, clamp, or fixture. Never hold material by hand during drilling or milling.
Keep hands, loose clothing, jewelry, and hair away from rotating tooling and moving components.
Do not measure, adjust, reposition a workpiece, or remove chips while the spindle is rotating.
Disconnect the machine from its electrical supply before performing maintenance, changing components, or accessing electrical or moving parts.
