In steel forging production, rough machining plays a crucial role between forging and final precision machining. Especially after heat treatment such as normalizing or quenching & tempering, proper rough machining ensures dimensional stability and prepares the component for final processing.

1. Removing Machining Allowance

Forged blanks are designed with machining allowance. Rough machining helps to:

• Remove scale and surface imperfections
• Eliminate excess material
• Prepare for dimensional control

It also allows preliminary inspection of internal structure conditions.

2. Reducing Residual Stress Impact

After heat treatment, internal stress may remain. Rough machining can:

• Release part of the residual stress
• Detect potential deformation early
• Minimize dimensional deviation in final machining

This is particularly important for forged crane wheels and heavy-duty forged shafts.

3. Establishing Accurate Machining Reference

Rough machining establishes positioning references for precision machining, helping to:

• Improve efficiency
• Ensure dimensional consistency
• Reduce rework risks

For heavy open die forgings and industrial steel components, rough machining is a key stage in the manufacturing process.
