13-Inch Swing Over Bed
The GHB-1340A provides a 13-inch swing over the bed, giving the operator a substantial working envelope for cylindrical and appropriately shaped metal components.
This capacity is useful for machining:
- Shafts
- Bushings
- Pins
- Spacers
- Couplings
- Adapters
- Machine components
- Fabricated cylindrical parts
Actual usable capacity depends on the workpiece geometry, tooling, chuck configuration, and other machine limitations.
40-Inch Distance Between Centers
The 40-inch distance between centers allows the lathe to accommodate relatively long workpieces.
Long components can be supported between the headstock and tailstock, helping maintain stability during turning operations. For particularly long or slender workpieces, an appropriate steady rest or other support should be used where applicable.
Geared-Head Transmission
The GHB-1340A uses a geared-head drive system designed for metalworking applications.
A geared head provides direct mechanical transmission between the drive system and spindle, offering a robust arrangement for turning and other machining operations.
The transmission allows the operator to select an appropriate spindle speed for the material, workpiece diameter, cutting tool, and machining operation.
Versatile Machining Operations
The GHB-1340A is designed to perform a broad range of conventional lathe operations.
Turning
Reduce the outside diameter of a workpiece or machine multiple stepped diameters.
Facing
Create a flat, perpendicular surface on the end of a workpiece.
Threading
Cut external threads for shafts, adapters, fittings, and other components.
Boring
Enlarge or finish an existing hole with a boring tool.
Drilling
Drill holes using appropriate tooling mounted through the tailstock.
Chamfering
Produce angled edges to remove sharp corners or prepare components for assembly.
Thread-Cutting Capability
Threading is an important function of a general-purpose engine lathe. The GHB-1340A can be configured for thread-cutting operations, making it useful for both manufacturing and repair work.
Typical applications include:
- Restoring damaged threads
- Producing custom threaded components
- Machining threaded shafts
- Fabricating adapters
- Creating specialized machine parts
The correct tooling, spindle speed, feed, and cutting depth should always be selected for the desired thread specification and workpiece material.
Tailstock
The tailstock provides support for longer workpieces and can accommodate appropriate tooling for operations such as drilling.
When turning a component between centers, the tailstock helps maintain workpiece support and can improve stability. Proper alignment between the headstock and tailstock is important for accurate machining.
Heavy-Duty Construction
The GHB-1340A is designed as a floor-standing metalworking lathe with a rigid structure intended to provide a stable machining platform.
Machine rigidity is important when performing turning, boring, and threading operations because unwanted vibration can affect surface finish, dimensional accuracy, and tool life.
Proper leveling, workholding, tooling selection, and routine maintenance are also essential to achieving accurate results.
Typical Applications
The JET GHB-1340A is suitable for:
- Machine shops
- Maintenance departments
- Metal fabrication
- Equipment repair
- Manufacturing
- Job-shop machining
- Prototype production
- Custom part fabrication
- General metalworking
- Industrial repair work
Common Uses
Shaft Machining
Turn, face, chamfer, or thread shafts used in machinery and equipment.
Bushing and Spacer Production
Produce cylindrical bushings, sleeves, spacers, and similar components.
Repair Work
Restore worn or damaged machine components where replacement parts are unavailable.
Custom Fabrication
Manufacture one-off or small-batch metal components to specified dimensions.
Thread Repair
Restore damaged external threads or produce new threaded sections.
Benefits for Professional Users
13-Inch Swing
Provides a useful working envelope for a broad range of cylindrical metal components.
40-Inch Between Centers
Allows longer workpieces to be machined between the headstock and tailstock.
Geared-Head Drive
Provides a robust mechanical transmission designed for general-purpose metalworking.
Threading Capability
Expands the machine's usefulness beyond basic turning and facing.
Manual Control
Gives machinists direct control over cutting operations, making the machine suitable for custom work and job-shop applications.
Versatile Machine Configuration
Supports common operations including turning, facing, boring, drilling, chamfering, and threading.
Maintenance
Regular maintenance is important for maintaining machining accuracy and extending the service life of the lathe.
- Keep the bed and ways clean and free of chips.
- Lubricate machine ways and specified lubrication points regularly.
- Maintain proper gearbox lubrication.
- Inspect cutting tools for wear.
- Check chuck jaws and workholding components before operation.
- Keep the tailstock clean and properly aligned.
- Inspect drive components for unusual noise or wear.
- Check fasteners and machine mounting periodically.
- Keep the machine properly leveled.
- Follow JET's recommended maintenance schedule.
- Disconnect electrical power before servicing the machine.
Safety Considerations
Always use appropriate eye protection, hearing protection, safety footwear, and task-specific PPE while operating the lathe.
Secure every workpiece firmly in the chuck, collet, or between centers before starting the spindle. Remove the chuck key before operation.
Keep hands, loose clothing, jewelry, and hair away from rotating components.
Never attempt to measure, adjust, clean, or remove chips from a rotating workpiece.
Use the correct cutting tool, spindle speed, feed rate, and depth of cut for the material and machining operation.
Long workpieces should be properly supported to prevent excessive deflection or whipping.
Stop the machine completely before making adjustments, changing tooling, or removing a finished workpiece.
Disconnect and isolate the electrical supply before performing maintenance or servicing internal components.
