Realizing Large-Scale Savings On Large-Scale Parts
Converting big square bars to largely round tie bars used to require 24 hours per piece at Oak Products. The Sturgis, Michigan, company can now complete the same job in 8 hours. How did the company slash its machining times and realize substantial cost savings? Oak attributes the turnaround to process re-engineering involving aggressive mill-turning and tooling geared to stand up to the challenge.

Keeping Accuracy Within Reach
Part quality is at risk if a machining center cannot hold tolerances at the farthest reaches of its work envelope. This makes volumetric accuracy a key indicator of a machine's performance. One machine tool builder discusses the implications.
