Definition: Automatic Screw Machine is a fully automated machining tool, typically a single-spindle or multiple-spindle bar stock turret lathe, used for high-volume production of precision parts, especially screws and similar fasteners.
Key Features
- Automation:
- Function: Performs various machining operations automatically, including cutting, threading, and finishing.
- Operation: Operates with minimal manual intervention, often using pre-set programs and automatic tool changes.
- Spindle Configuration:
- Single-Spindle: Features one spindle that performs all operations sequentially.
- Multiple-Spindle: Equipped with multiple spindles to perform several operations simultaneously, increasing productivity.
- Turret Mechanism:
- Function: Contains a rotating turret with multiple tool stations, allowing for quick tool changes and diverse machining operations.
- Operation: The turret rotates to bring the required tool into position for each operation.
- Bar Stock Feeding:
- Function: Automatically feeds bar stock into the machine for continuous processing.
- Operation: Uses a bar feeder to load and advance stock material through the machine.
Operation
- Setup:
- Tooling: Tools are set up in the turret according to the required operations.
- Programming: Machine parameters and sequences are programmed for specific parts.
- Machining:
- Feeding: Bar stock is fed into the machine.
- Processing: The machine performs various operations such as turning, threading, and drilling.
- Ejection: Finished parts are automatically ejected from the machine.
- Automation:
- Tool Changes: Automatically changes tools from the turret as needed.
- Part Handling: Includes mechanisms for handling and ejecting finished parts.
Applications
- Fastener Production:
- Function: Commonly used for manufacturing screws, bolts, nuts, and other fasteners.
- High-Volume Manufacturing:
- Function: Ideal for producing large quantities of small, precision parts efficiently.
- Precision Parts:
- Function: Used for producing parts with high precision and tight tolerances.
Advantages
- High Efficiency: Capable of producing large quantities of parts quickly with minimal manual intervention.
- Precision: Provides high accuracy and repeatability in part dimensions.
- Reduced Labor: Minimizes the need for manual labor and operator involvement.
Summary
Automatic Screw Machines are advanced machining tools designed for high-volume production of precision parts. With features like automation, turret mechanisms, and bar stock feeding, these machines efficiently produce screws and similar components with high precision and minimal manual intervention. They are widely used in fastener production and other applications requiring high-volume manufacturing of small, accurate parts.
