Pressure Straightening Machine

Pressure Straightening Machine
The press straightening machine is used for correcting local bending and deformation of bars, shafts, tubes, profiles and forged parts. It is especially suitable for point-by-point correction after heat treatment, machining, forging or transportation.
The equipment applies controlled hydraulic pressure to selected bending positions while the operator or measuring system checks straightness and adjusts the correction amount. It can handle high-strength steel parts and larger workpieces that are not suitable for continuous roll straightening.
Typical applications include shaft straightening, round bar correction, tube straightening, mold component repair, forged part finishing and heavy mechanical part rework.
The machine features strong pressing force, stable hydraulic performance, easy operation and flexible tooling options. It helps reduce scrap rate and improves dimensional accuracy before final machining or inspection.
