CNC Machining Of Castings And Forgings

Castings and forgings are common raw forms for structural parts. Our factory has strong experience in CNC machining of castings and forgings. We machine ductile iron, steel castings, aluminum castings, and forged steel. The main difference from bar stock is uneven material allowance. Castings may have porosity, sand holes, or forging laps. This requires careful tool path planning. Our programming team uses adaptive cutting strategies. These adjust to the actual material condition. This avoids air cuts or sudden heavy cuts that can damage tools. Our four-axis CNC machining centers have enough power and rigidity to handle hard casting surfaces and uneven allowances in product.

Castings and forgings often have high residual stress. If you remove too much material at once, the part may deform. Before CNC machining of castings and forgings, we discuss stress relief annealing or aging with the customer. During roughing, we remove material in layers and symmetrically. This helps release stress gradually. We also allow enough time for the part to stabilize before finishing. Our CMM can check complex spatial dimensions on large castings and forgings. This ensures the finished part matches the design. We have long-term experience in product for construction machinery, industrial equipment, and automotive parts. We process over 100,000 castings and forgings every year.

We accept custom CNC machining of castings and forgings. We can pre-inspect the blank quality before machining. If we find any issues, we will inform you immediately. We also provide the full process from roughing to finishing. This helps you turn your raw blanks into finished parts efficiently. Let us handle your product with expertise and care.
