The Speedtech ExtReme & ATS AFX Spindle Manufacturing Process
Like most spindles, cast components are typically formed by pouring molten metal into a sand mold and afterwards getting some final machining. Since this process is relatively inexpensive, quick and easy to do it’s often the choice for high production parts, but there are a few draw backs. While a cast part is relatively strong, the mold can experience some shift and therefore cast parts can have greater tolerances. This means less precision and less consistency. On top of that because the metal is simply poured into the mold it’s not possible to compact the molecules super tightly together, leaving some strength out of the equation. To make up for this weakness, often heavier metal compounds have to be used, for example iron instead of aluminum.
A forged part is a completely different concept, and with Speedtech ExtReme and our ATS Tall AFX forged aluminum spindles you get an end result that is lighter than cast iron, stronger than cast iron or even billet aluminum and much more consistent with ultra tight precision machined tolerances.
Be sure to ask your sales rep about these different options to customize your frame to your needs.
