Tip wear can lead to a host of issues for tablet design. Here, Bill Turner, technical service manager, tooling and tablets, and Kevin Queensen, technical service support tooling and tablets, Natoli Engineering, discuss the steps needed to avoid wear in tooling.
Inspector
Wear to the edges of punch tips is overlooked in many tooling inspection procedures. Many factors can cause tip wear, including poor tablet and tool design, granulation characteristics, and improper steel selection for the application. While inspection technicians typically pay attention to the punch cup face, tablet defects are in fact more often related to punch tip land and outer edge wear.
