A specialized tooling system utilized in machining enlarges existing holes accurately and smoothly. This system typically comprises a tool holder and a radially adjustable cutting tool, allowing for precise diameter control. A common application involves refining a pre-drilled hole to meet tight tolerances, crucial for components like engine cylinders or bearing housings.
Precise hole enlargement is essential for creating high-quality, functional components across various industries. This tooling offers significant advantages over other methods by enabling fine adjustments and superior surface finishes, reducing the need for subsequent finishing operations. Historically, achieving such precision required laborious manual processes. The development of this tooling system marked a significant advancement in machining efficiency and accuracy.
