A
gang-drill machine is used for
large-batch production as it consists of multiple drilling heads mounted on the same table. This setup allows different operations, such as drilling, reaming, and tapping, to be performed simultaneously on the same workpiece without changing the setup, increasing production efficiency and reducing cycle time.
Gang-Drill Machine Features:
· Multiple drilling spindles or heads aligned on a single work table.
· Different tools can be mounted on each spindle for various operations.
· Ideal for mass production where multiple holes or operations are required in quick succession.
Applications:
· Used in automotive, aerospace, and manufacturing industries for high-volume production.
· Common for producing engine components, brackets, and plates.
Advantages:
· Increased productivity due to parallel operations.
· Reduced handling time and tool setup changes.
