The Answer to Small Punch Grinding

EZPUNCH Simplifies the Grinding of All Your Complex Parts

EZPUNCH software is the Weldon solution to more productive grinding of pharmaceutical punches, sheet metal punches, forming punches and other complex parts up to 1.75" in diameter and without any length to width limitations.

EZPUNCH is simple, fast, straightforward programming software that enables your operator to describe flexible non-round convex shapes with up to six sides, and equilateral polygons up to 12 sides using 14 basic shapes.

EZPUNCH is easy because it communicates in a language your operator can understand quickly without previous programming experience. With minimal training the operator can interact with the system to create the desired grinding program.

And for more versatility, EZPUNCH gives you the option to grind the workpart from either a round blank or a preformed shape.

EZPUNCH Gives You More

• Can define any polygon, regular or irregular, up to 6 sides
• Operator can modify process parameters
• Has centerline offset capability
• Radii, arcs and blends are completely CNC generated
• Greater programming speed and flexibility off-line on a PC
• Creates a standard G and M code program
• Import any drawn shape using DXF
