When you’re building a drift/race car, the transmission is more than just a gearbox - it’s the link between your hard work and the pavement. At Fisch Racing Tech, we’ve always believed that the only way to ensure that link never breaks is to own the manufacturing process from start to finish.
Today, we’re pulling back the curtain on a major addition to our shop: the Okuma Vertical Lathe.
Bringing our flywheel production in-house wasn't just about logistics; it was about physics. Here is why we made the investment and what it means for your next manual swap.
THE PHYSICS OF THE VERTICAL SPINDLE
In the world of machining, orientation matters. While many components are turned on traditional horizontal lathes, the specific geometry and weight of a Billet Chromoly flywheel benefit significantly from a vertical approach.
1. Gravity-Induced Stability In a vertical lathe, the raw billet sits flat on a rotating table. Gravity works with us, naturally seating the part and keeping it perfectly centered. In a horizontal setup, gravity is a constant force pulling the part downward, away from the spindle's center. By machining vertically, we eliminate the potential for minute weight-shifting during the cutting process, ensuring the structural integrity of the flywheel is maintained throughout its entire circumference.
2. Harmonic Dampening and Mass Our Okuma isn't just a machine; it’s a massive industrial casting designed to absorb energy. During high-speed machining, cutting tools create high-frequency harmonics (vibrations). Because of the sheer mass and rigidity of the Okuma, these vibrations are dampened before they can reach the part. This results in a cleaner, more consistent surface finish on the friction face, essential for the heat-cycling demands of a high-performance clutch.
EXPERTISE UNDER OUR ROOF
A machine is only as good as the hands operating it. By bringing this technology in-house, our Red Seal machinists have total oversight of every cut, every chamfer, and every inspection.
We no longer rely on external machine shops that might not understand the stakes of a 7,000 RPM clutch kick. From the moment the raw material is loaded to the final quality check, your flywheel is handled by enthusiasts. This isn't just about quality control; it’s about accountability.
WHAT THIS MEANS FOR YOUR BUILD
We know the frustration of an unfinished project car sitting on jack stands because of backordered parts or "universal" kits that don't actually fit. Our transition to in-house manufacturing is designed to solve two major pain points for our customers:
- Eliminating Bottlenecks: By controlling our own production schedule on the Okuma, we can significantly reduce lead times on our CD009 and CD00A adapter kits, if they were ever to be backordered.
- A Complete System: We don’t sell "plates" or mismatched components. We sell engineered bellhousing systems. Because we machine the flywheels to match our precision-cast bellhousings in the same building, the stack-height and alignment are guaranteed.
THE GOAL: MORE SEAT TIME
Every investment we make in the shop, like the Okuma Vertical Lathe, is driven by one goal: getting you out of the garage and onto the track. We build parts for people who want to do it right the first time, using professional-grade equipment and proven engineering.
When you install a Fisch Racing Tech kit, you’re installing a product built by enthusiasts, for enthusiasts, on the best machinery available.
