The Problem:

Maximizing machine uptime in a fabrication operation is usually a matter of taking a series of small steps as opposed to one giant leap. Over the past several years Mate has consulted with many customers on ways to maximize uptime. While the first step in successful punching is to pay close attention to the quality and features of the punched parts, Mate discovered that incorrect turret alignment is a leading cause of reduced uptime and poor tool life.

Superior piece part quality, extended machine life and longer tool life is achieved when the upper and lower turrets of a punch press are precisely aligned. New turrets are aligned by factory technicians and verified during installation. After use, turrets often require some realignment. Press uptime will be increased if accurate station alignment is maintained. Alignment ensures the punch enters the center of the die, resulting in even die clearance around the cutting edge, the best possible tool life and higher quality parts.

The Mate Solution:

There are two types of alignment, concentric and angular.

• Concentric alignment means that the center line the upper tool holder and the lower die holder are in line.
• Angular alignment means that the edge of a punch should be parallel with the edge of the die.

Realigning the Turret

Alignment tools should be used as soon as there is evidence of misalignment.  The alignment tools refresh the precision orientation of the upper and lower tools, allowing the punch to enter the center of the die. If possible, align the station as a periodic preventive maintenance measure to prevent poor quality parts and damage to tools.

Mate Pilot™ Calibration System

One such alignment tool is Mate’s Pilot calibration system, which ensures precision concentric and angular alignment of thick turret punch presses. The Pilot™ Calibration System provides a simple and accurate way to verify the precise alignment of a punch press station and perform station alignment when required.
