Not all spline shafts are created equal. ⚙️

These custom spline shafts required a combination of precision machining, heat treating, and finish grinding to achieve tight tolerances and repeatable performance. After heat treat, the shafts were precision ground to hold a tolerance within a tenth, while maintaining critical geometry across multiple features.

Additional processes included:
✔️ Precision ground bearing surfaces
✔️ Threaded features
✔️ External splines
✔️ Plunge EDM hex in the bore for internal drive geometry

Projects like this are where process control and attention to detail make all the difference, especially when heat treat movement, concentricity, and final fit all have to work together.

From machining to finishing, this is the kind of precision manufacturing our team takes pride in every day.

Not your average shaft and not your average process. ⚙️

This custom shaft was machined from ETD 150 and built for a demanding application. Between the tight tolerances, a custom spline , and the long keyway with additional keyway features, this part required a lot of planning and precision from start to finish.

Harder material and tighter specs always bring challenges, but that’s where our team does its best work—figuring it out, dialing it in, and getting it done right.

If you’ve got a complex component that needs a custom approach, we’re always up for it.

Not every career path starts with experience—some start with curiosity.

Alex joined HM Manufacturing in 2018 right out of high school after developing an interest in manufacturing early on. What began as curiosity—sparked by seeing complex components like planetary gears—has grown into a role supporting CAD, Quality, and Engineering.

Today, Alex helps turn prints into finished parts used in demanding, real-world applications. His growth reflects what’s possible with consistency, a willingness to learn, and taking on new challenges over time.

We’re proud to have Alex apart of the HM team!

Precision where it connects. This straight edge spline, machined from 6061 aluminum, is designed for clean engagement in motor and pump couplings—keeping everything aligned, efficient, and reliable.

While it may look simple, every feature has a purpose. This one even serves as an assembly tool for a custom shaft, proving that even the supporting pieces play a critical role in the bigger picture.

Finished with a final tapped feature to complete the job.

Precision matters where it counts. These aluminum pulleys are machined with tight tolerances on critical features, ±.0005” on the bore, to keep high-performance food & beverage equipment running smooth, consistent, and reliable—cycle after cycle.

Built for performance. Made to last.

Not all timing belt pulleys are created equal.

This 72-tooth Supertorx® pulley (8 mm pitch) isn’t a profile you see every day, but it’s one we’re always ready to produce when customers need performance beyond standard geometries.

🔹 Aluminum construction
🔹 Precision machined oblong mounting slots for fine adjustment
🔹 Sulfuric anodize with seal coat for wear resistance
🔹 ~6” diameter × 3.25” length
🔹 Tight runout and balance requirements

At HM Manufacturing, whether it’s common profiles or the ones you only see once in a while, the expectation stays the same: precision, repeatability, and performance.

Looks simple.
Isn’t.

Tight concentricity. Clean tooth geometry. Critical fits. Every edge of this component has a job to do.

Precision isn’t a feature. It’s the standard.
