Why is forging better than machining?
Why is forging better than machining? Forging provides a higher level of structural integrity than any other metalworking process. By eliminating structural voids that can weaken parts, forging provides a level of uniformity to help maximize part performance. During machining, grain ends are exposed, making parts more susceptible to weakening and cracking. What are the […]
