What Are Turret Presses?
Turret presses are machines used in metal fabrication to punch holes and perform various operations on sheet metal. They feature a rotating turret that holds multiple tooling stations, allowing for quick tool changes and versatile processing capabilities. Turret presses can perform tasks such as: punching, forming, tapping, contour cutting, and deburring.
How Does a Turret Punch Press Work?
Turret presses are essential tools in metalworking and ammunition reloading. Their operation involves a rotating turret that holds various dies, facilitating quick and precise processing. Here’s a step-by-step guide to using one:
A metal sheet is positioned beneath the tooling turret of the turret press manually or automatically.
The CNC control system automatically selects the appropriate tool for the desired operation. For a manual turret press punch, the operator manually chooses and positions it.
The turret rotates to bring the selected tool into position above the metal sheet. In manual operation, the operator rotates the turret to position the chosen tool above the metal sheet, adjusting it using a control panel for precise alignment.
Utilizing either a lever, hydraulic system, or motor, the press’s punch descends, transferring force through the tool onto the metal sheet, thereby shaping or perforating it as desired.
The turret may be rotated to select different tools for subsequent operations, allowing for a wide range of shapes and holes to be created without changing the tools sitting in the punch holders.
The material can be repositioned either manually by an operator or automatically through automated processes.
When all features have been fabricated in the current workpiece, it is removed (manually or automatically) from the turret press punch, and the next blank is loaded.
