How Racing Engine Parts Are Made! CP Carrillo Factory Tour & Behind The Scenes (Rods & Pistons)
What happens here
The initial machining of pistons involves rough milling operations carried out on advanced CNC horizontal milling machines. CP-Carrillo has transitioned from numerous single-operation stations to using 'palletized' or 'tombstone' systems, allowing a single operator to load multiple machines simultaneously. This setup enables continuous machining in the back while new parts are loaded in the front, significantly enhancing production efficiency and speed. The process also includes machining pistons from solid aluminum slugs (billets), which allows for flexible production of prototypes or parts with frequently changing designs without the need for specialized forging dies.
Goal: Execute initial material removal and shaping of pistons using CNC machinery.
Tools and materials
- CNC Horizontal Milling Machines N/A — Initial rough machining operations on piston forgings and billets
- Palletized/Tombstone Systems N/A — Efficiently loading multiple piston blanks for continuous machining
- Aluminum Billets — Raw material for pistons that are entirely machined, offering design flexibility
- Piston Forgings N/A — Pre-shaped raw material for pistons that undergo further machining
