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

What they say

Hide

different operations to using palletized or Tombstone systems and and horizontal Milling machines so you can load multiple machines as a single operator and you can do Machining in the back while you're loading the front and then it'll cycle through and it helps with your production for all these machines sort of doing the same thing they're just different things are all those three machines right there are actually doing the identical something they're tooled up the same there's nothing different about them this particular one we actually do a lot of the the old school big area style Parts on there and then we can flip and flop however we need to based on quantities and you know just all the other variables that come into play if a machine goes down or you're servicing one or whatever the case will be they also do billets start with slugs of aluminum and we manufacture any shape we want out of that so that that way we can either do prototyping or we might do something where it's just not gonna be frequent enough to forge it maybe you don't want to invest the money in the tooling or maybe there's changes to it like an NHRA Pro Stock thing where you change it so frequently you don't want to be locked into a fortnight here's before and after
