Straightening Solutions Provider
We provide an excellent selection of shaft straightening equipment designed to address typical manufacturing deformities. Applications range from precise office equipment, such as medical drill bits, to huge construction equipment shafts.
What are Straightening Solutions?
Straightening is a mechanical working procedure used to achieve precisely what the term implies. To straighten long, narrow, and thin pieces to a certain tolerance. Long, narrow, and thin components might flex during heat treatment due to distortion.
The deformation results from the fact that when steel is heated to austenitizing temperature, its strength is much lower than at room temperature. Long, narrow, and thin sections deform in the heated, austenite condition due to the weight of the part acting on itself while it lies inside the furnace. This distortion, or bending, can be repaired by physically deforming the steel and reversing the bending within the steel’s mechanical working parameters.

Mechanical Shaft Straightening Process
- Create a Bent Shaft Survey Map to determine the location and amount of bend correction required.
- Install the bent shaft in a suitable press as shown in Figure 3. Rotate the shaft so that the “high side” of the bend with the greatest magnitude of deflection is positioned directly under the ram of the press. Mount a dial indicator as shown in Figure 3 to monitor shaft deflection.
- Slowly apply force to the shaft while watching the amount of deflection on the dial indication. To gain a feel for the shaft’s responsiveness to bend correction, work in increments and then back off the press to see the results.
- Repeat the process until the desired shaft straightness is obtained.
Advantages and Disadvantages of the mechanical shaft straightening ?
Advantages
- For many situations, the mechanical technique is closer to fixing the fundamental cause of the problem than any other shaft straightening process. As a result, the mechanical method is frequently regarded the preferred way.
- With the right setup, the mechanical method’s repair cycle may be completed rather rapidly. Observing the dial indicator reading allows for easy and direct monitoring of the outcomes throughout the operation. For a particular shaft, the amount of adjustment necessary is fairly consistent and reproducible.
- Because the mechanical shaft straightening method does not employ heat, it may be used to a broader spectrum of shaft materials than the spot-heating approach.
Disadvantages
- To fix the shaft’s bending, the mechanical shaft straightening technique requires an acceptable capacity press. For big shafts, the availability of a suitable press and material handling equipment may be a constraint. For the same reasons, this procedure might be difficult to do while the shaft is in place.
