What happens here
After rough milling, pistons undergo further machining on CNC lathes. This process involves operations such as facing the top of the piston, turning the outer diameter (OD), and roughing out the ring grooves. The goal at this stage is to remove as much material as possible to relieve internal stresses and minimize subsequent machining requirements. This is a critical step in achieving the desired shape and preparing the piston for final finishing, ensuring that less material needs to be removed in later, more precise operations.
Goal: Refine piston shape, create initial features, and relieve material stress.
