Punch Former

Punch Former Details

Punch Former is a precision tool used in grinding operations to hold punches and other cylindrical or conical workpieces securely during the grinding process. Punch formers are commonly used in tool and die making, particularly for producing or regrinding punches, which are tools used for stamping, cutting, or shaping metal or other materials. The punch former allows for high-precision grinding, enabling the machinist to achieve perfect symmetry, sharp edges, and accurate dimensions.

Key Components

Base Plate: The base plate serves as the foundation for the punch former. It is designed to be securely mounted onto the grinding machine’s work table, providing a stable platform for the tool.

Rotating Mechanism: This mechanism allows the punch to rotate smoothly during the grinding process, ensuring even wear and a consistent finish. Some punch formers feature indexable rotation for precise angular adjustments.

V-Block or Chuck: The V-block or chuck securely holds the punch or workpiece in place. It ensures that the workpiece remains stationary and aligned correctly during grinding, which is crucial for achieving precise results.

Tilting Mechanism: Many punch formers come with a tilting mechanism that allows the workpiece to be positioned at various angles for grinding different profiles and shapes. This feature is especially useful for creating punches with complex geometries.

Collet or Clamp System: The punch former may use a collet or clamp system to secure the punch, allowing for easy and precise adjustment during setup.

Advantages

High Precision: Punch formers provide the accuracy needed to produce or regrind punches with exact dimensions and sharp edges. This precision ensures that the punches perform reliably in stamping operations.

Versatility: With the ability to hold a wide range of punch sizes and shapes, punch formers can be used for various grinding tasks, from simple cylindrical punches to complex conical or angled shapes.

Efficient Grinding: The rotating and tilting mechanisms of the punch former make it easier to grind punches evenly and efficiently. This reduces the time and effort required to achieve the desired finish.

Enhanced Tool Life: Regular regrinding of punches using a punch former can extend the life of the punches, reducing the need for costly replacements and ensuring that the punches continue to perform optimally.
