Straightening Press Services

Lange Grinding & Machining provides straightening press services for customers with out-of-flat plates, bent components, weldments, bars, shafts, fabricated parts, and heavy industrial workpieces. When a part has moved, warped, bowed, or distorted from welding, heat, stress, handling, machining, or heavy use, straightening may be an important step before grinding, machining, inspection, or final assembly.

Our straightening press capability helps customers correct parts that are not sitting flat, are difficult to machine, or need to be prepared for additional processing. Using our in-house straightening press, Lange can generally press pieces up to 6.5″ thick and help determine whether straightening, grinding, machining, or a combination of services is the right approach for your part.

Industrial Straightening Press Services

Straightening press work is used to help correct metal parts that are bent, bowed, warped, twisted, or out of flat. For many industrial components, straightening is not the final step by itself. It is often part of a larger process that may include Blanchard grinding, surface grinding, CNC machining, planer milling, inspection, and final finishing.

Lange’s straightening press services are useful when a part needs to be brought closer to the required condition before another operation can be completed correctly. If a plate, weldment, or machined component is not flat or properly aligned, it may not sit correctly for grinding, machining, layout, or inspection. Straightening can help create a better starting point for the next step.

When Straightening Press Work Is Needed

Industrial parts can move or distort for many reasons. Welding can introduce heat and stress. Heavy use can bend or deform components over time. Parts can also move during handling, fabrication, repair, or previous machining operations. When that happens, the part may need to be corrected before it can be finished or returned to service.

Customers often contact Lange for straightening press services when they have plates or components that are out of flat, bent, bowed, or no longer meeting the condition required for the next operation. Our team can review the part, dimensions, material, thickness, and project requirements to help determine whether press straightening is a practical solution.

Parts We Can Help Straighten

• Out-of-flat plates
• Bent industrial components
• Heavy weldments
• Bars, shafts, and fabricated parts
• Machined parts that moved during processing
• Repair parts from industrial equipment
• Components distorted by welding, heat, or stress
• Parts that need correction before grinding or machining

Plate Straightening and Out-of-Flat Part Correction

Plate straightening is one of the most common reasons customers need straightening press work. A plate that is out of flat may be difficult to grind, machine, inspect, or install. Correcting the part before the next operation can help improve setup, reduce processing issues, and create a better foundation for final work.

Lange can help customers with plate straightening and out-of-flat part correction as part of a larger machining and grinding workflow. Depending on the project, the part may move from straightening to surface grinding, Blanchard grinding, planer milling, CNC machining, or inspection.

Straightening Before Grinding or Machining

Straightening press services often support other Lange capabilities. A part may need to be straightened before it can be ground flat, machined accurately, or inspected properly. This is especially important for heavy industrial parts where setup, flatness, alignment, and handling all affect the final result.

Our straightening press services can work together with Blanchard grinding, surface grinding, planer milling, CNC machining, and quality control. Keeping these services under one roof can help reduce outside handoffs and give customers a more coordinated process.

Supported by Lange’s 350 Ton Straightening Press

This capability is supported by Lange’s 350 Ton Straightening Press. The equipment gives our team the force needed to support heavy-duty straightening work for large industrial parts, plates, weldments, and components that need correction before additional processing.

The equipment page explains the machine itself, while this Capabilities page focuses on the straightening press service, the types of problems it helps solve, and how the process fits into a larger machining and grinding project.

Useful for Repair, Rebuild, and Production Support

Straightening press work can be valuable for both repair and production-related projects. In repair situations, a part may be too valuable, too large, or too specialized to replace without first considering correction and rework. Straightening may help prepare the part for additional grinding, machining, or inspection so it can return to service.

In production support, straightening may be needed between fabrication, welding, machining, or finishing steps. A component that moves during processing may need to be corrected before the next operation can be completed properly. Lange can review the part condition and recommend the best path forward.

Industries We Support

Lange Grinding & Machining supports customers across demanding industrial markets, including aerospace, automotive, construction, earth moving equipment, military, mining, paper, power generation, steel mills, and other heavy industrial applications.

These industries often work with large, heavy, or specialized parts that must perform under load, heat, pressure, wear, or repeated use. Straightening press services help support those customers when parts need correction before grinding, machining, assembly, repair, or final inspection.
