Machining post-weld is a vital step in the fabrication process when large-scale weldments require precision machining. The welding process distorts the raw material, which ruins any tolerances in nearby machined areas. When projects require precision machining and extensive welding, machining post-weld becomes necessary to preserve tolerance integrity. This becomes a challenge as weldments grow larger and more complex, such as those commonly required in agricultural, mining, and other industrial equipment.
Changing the Landscape of Machining Post-Weld
HMMI has a long history of proactively addressing the growing needs of their customers by investing in newer, larger, more efficient manufacturing equipment. As post-weld machining requirements grew larger, multiple machining operations were required to achieve acceptable results. However, when HMMI was approached to complete a project that would require massive post-weld machining, this method would no longer suffice. With the goal of further enhancing quality, efficiency, and size capacity, HMMI expanded their capabilities with the introduction of the 5-axis Okuma bridge mill machining center.
Embracing Advanced Technologies for Precision Results
The Okuma, with an impressive work window spanning 21’ by 13’ by 6’, is one of the largest post-weld machining centers in the Midwest and more than tripled HMMI’s post-weld machining size capacity. The Okuma boasts an 80,000-pound table capacity with two 20-ton overhead hoists, advanced CNC capabilities with a 100-tool magazine, through-tool coolant for deep holes, and a 90° attachment, which all combine to drastically reduce setup and cycle times while enhancing overall quality. This powerful machine quickly earned its place as it rapidly churned out precision results in some of the area's largest weldments.
Improving Quality in Oversized Components
HMMI wouldn’t be where it is today without the Okuma and its ability to produce repeatably high-quality results in the largest, most complex requirements. However, we are always striving to proactively meet the growing needs of our customers. While the 5-axis Okuma will always be a staple in machining post-weld at HMMI, we are excitedly awaiting our newest, largest, most advanced oversized capabilities to date, the Durma Press Brake!
