Specification note: Exact motor power, spindle bore, spindle nose, spindle taper, spindle-speed range, thread ranges, carriage travel, collet capacity, electrical requirements, machine dimensions, and weight should be confirmed against the specific JET stock number and current manufacturer's documentation. These details can vary by configuration or production revision.
13-Inch Swing Capacity
The 13-inch swing over the bed provides a useful machining envelope for a wide range of cylindrical workpieces.
The machine can be used for components such as:
- Shafts
- Bushings
- Pins
- Spacers
- Couplings
- Adapters
- Rollers
- Custom machine components
The actual maximum workpiece size depends on the component's shape, chuck or collet setup, tooling, and other machine clearances.
40-Inch Distance Between Centers
With a 40-inch distance between centers, the GHB-1340A can accommodate relatively long workpieces.
Long components may be supported between the headstock and tailstock for turning operations. When machining long or slender stock, additional support such as a steady rest may be appropriate to control deflection and vibration.
Collet Closer
The collet closer is particularly useful when machining smaller cylindrical workpieces or performing repetitive operations.
A collet can provide consistent workholding and quick loading compared with repeatedly positioning individual pieces in a conventional chuck.
Potential advantages include:
- Faster workpiece changes
- Consistent positioning
- Secure gripping of suitable stock
- Improved repeatability for repetitive jobs
- Convenient handling of smaller cylindrical components
The appropriate collet size and type should be selected according to the actual workpiece and machine configuration.
Geared-Head Design
The GHB-1340A uses a geared-head transmission to transfer drive power to the spindle.
This configuration is well suited to general-purpose metalworking because it provides a robust mechanical drive arrangement for turning and other machining operations.
The operator can select an appropriate spindle speed according to the material, workpiece diameter, cutting tool, and machining operation.
Threading Capability
The GHB-1340A is designed for thread-cutting operations, expanding its usefulness beyond basic turning and facing.
Threading applications can include:
- Producing threaded shafts
- Restoring damaged threads
- Manufacturing custom adapters
- Producing threaded bushings
- Fabricating specialized machine components
Proper tooling, cutting parameters, and machine settings should be selected for the required thread specification.
Tailstock
The tailstock provides additional support for longer workpieces and can accommodate suitable tooling for operations such as drilling.
When turning between centers, the tailstock helps stabilize the workpiece. Proper alignment is essential when machining components where dimensional accuracy is important.
General Machining Capabilities
The GHB-1340A can perform several common lathe operations.
Turning
Reduce the diameter of a workpiece or machine multiple stepped sections.
Facing
Create a flat surface perpendicular to the workpiece axis.
Boring
Enlarge and finish existing holes with suitable boring tooling.
Drilling
Produce holes using appropriate tooling mounted in the tailstock.
Threading
Cut external threads for shafts, fittings, adapters, and other components.
Chamfering
Remove sharp corners or create angled edges for assembly and finishing.
Typical Applications
The JET GHB-1340A with collet closer is suitable for:
- Machine shops
- Maintenance departments
- Metal fabrication
- Equipment repair
- Custom machining
- Manufacturing support
- Job-shop production
- Prototype work
- Small-batch component production
- General metalworking
Common Uses
Repetitive Small-Part Machining
The collet closer is useful when producing multiple similar cylindrical components where consistent workholding and quick loading are beneficial.
Shaft and Pin Production
Machine shafts, pins, spacers, and other rotational components to specified dimensions.
Repair and Maintenance
Restore worn components or manufacture replacement parts for machinery.
Threaded Components
Produce custom threaded parts or repair existing threaded sections.
Prototype Machining
Create one-off components and prototypes without requiring a CNC machining center.
Benefits for Professional Users
13-Inch Swing
Provides a substantial working envelope for general-purpose turning operations.
40-Inch Between Centers
Accommodates longer workpieces that can be supported between the headstock and tailstock.
Collet Closer
Makes repetitive machining of suitable smaller cylindrical components more convenient and consistent.
Geared-Head Transmission
Provides a robust drive arrangement for metalworking operations.
Threading Capability
Allows the lathe to perform specialized thread-cutting work in addition to conventional turning.
Versatile Manual Operation
Provides direct operator control for custom parts, repairs, prototypes, and small production runs.
Maintenance
Proper maintenance is important for preserving lathe accuracy and service life.
- Keep the bed and ways clean and free of chips.
- Lubricate ways and specified lubrication points regularly.
- Maintain the correct gearbox lubrication level.
- Inspect cutting tools for wear and damage.
- Keep the collet and collet closer clean.
- Check chuck, collet, and other workholding components before use.
- Inspect the tailstock for proper alignment and smooth operation.
- Check drive components for unusual noise or vibration.
- Keep the machine properly leveled.
- Follow JET's recommended maintenance intervals.
- Disconnect electrical power before servicing the machine.
Safety Considerations
Always wear appropriate eye protection, hearing protection, safety footwear, and task-specific PPE when operating the lathe.
Secure the workpiece correctly in the chuck or collet before starting the spindle. Ensure the collet closer is properly engaged and the workpiece is adequately supported.
Remove the chuck key and other setup tools before starting the machine.
Keep hands, loose clothing, jewelry, and hair away from rotating components.
Do not measure, adjust, clean, or remove chips while the spindle is rotating.
Use tooling, spindle speeds, feeds, and depths of cut appropriate for the workpiece material and machining operation.
Long workpieces should be supported appropriately to reduce deflection and vibration.
Stop the machine completely before changing tooling or making adjustments.
Disconnect and isolate the electrical supply before performing maintenance or servicing.
