- [What Is Blind Hole Broaching? Process, Tooling, and When to Specify It](https://keyway-spline-broaching.com/what-is-blind-hole-broaching/): Blind hole broaching is a machining process. It cuts keyways, splines, slots, and other profiles inside a bore that doesn’t go all the way through the workpiece. The tool enters from one end, machines the feature to a precise depth, and retracts — without ever exiting the opposite side of the part. That single constraint changes everything about how the process works. In standard through hole broaching, chips clear naturally through the open end. The tool moves along a continuous path, and the depth is set by the bore length. In blind hole broaching, none of that applies. Chip evacuation, tool […]
- [Electric Motors & Power Transmission: Components, Types, Applications & Selection](https://keyway-spline-broaching.com/electric-motors-power-transmission/): Electric motors convert electrical energy into rotational mechanical power. However, the motor is just the beginning of an industrial drive system. Power transmission components send rotation to the driven machine. They also manage speed, torque, direction, and mechanical connections.  A typical system has a motor shaft, a coupling, a gearbox, a secondary shaft, and a mounted gear, pulley, or sprocket. The connection between those parts matters as much as the individual components. A poorly matched keyway, spline, bore, or shaft can lead to assembly issues. It can also affect how the system transmits torque. For engineers, OEMs, machine builders, and manufacturers, […]
- [Involute Spline Broaching: Design, Process, Inspection, and Quote Requirements](https://keyway-spline-broaching.com/involute-spline-broaching-guide/): Involute spline broaching is a precision machining process used to form multiple, evenly spaced teeth inside a bore. Those teeth mate with an external spline to transmit torque while helping the connected parts maintain alignment. The process can produce repeatable internal profiles for power-transmission components. Success depends on aligning the spline specification, starting bore, material, access, tooling, datums, and inspection method. For engineers and buyers, the key question is not only whether the spline can be broached. It is whether the part is defined for reliable manufacturing, inspection, and assembly. Key Takeaways Involute spline broaching forms a curved tooth profile that […]
- [How Blind Keyways Are Machined in Closed-End Bores](https://keyway-spline-broaching.com/how-blind-keyways-are-machined-in-closed-end-bores/): A drawing lands on your desk with a bore that’s closed at one end and a keyway that has to stop short of the bottom. You send it out for a keyway broaching quote, and the shop replies with a question instead of a price: is the bore open on the far side? It isn’t — and that one detail changes how the slot has to be cut, priced, and inspected. Most internal keyways are produced by pushing or pulling a broach straight through the bore. A blind keyway takes that option off the table. When the slot has to end […]
- [C.A.M.S. Slotting Machines for Precision Internal Slotting](https://keyway-spline-broaching.com/c-a-m-s-slotting-machines-for-precision-internal-slotting/): A hub arrives at the bench with a blind internal keyway and a run of forty pieces.

- [Industrial Spline Broaching: A Complete Guide for Manufacturers](https://keyway-spline-broaching.com/industrial-spline-broaching/): Open up almost any gearbox, transmission, or drive shaft assembly and you will find splines somewhere inside. Not bolts. Not welds. Splines, a series of ridges and grooves cut along a shaft or inside a bore that lock two parts together so they rotate as one. Cutting those splines accurately, consistently, and at production volume is what industrial spline broaching does. It is one of those processes most people outside manufacturing have never heard of, yet it sits behind the reliability of everything from car transmissions to aircraft actuators to industrial pumps. This guide breaks down how the process works, why […]
- [What Is Spline Broaching and Why It Is Used in Mechanical Components](https://keyway-spline-broaching.com/what-is-spline-broaching/): Spline broaching is a precision machining process that comes up constantly in mechanical engineering and manufacturing conversations, yet a surprising number of people outside the machining world have never heard of it. I remember the first time I watched a broaching operation on a splined shaft component.  The tool passed through the workpiece in one clean stroke and what came out the other end was a perfectly formed spline profile, accurate and repeatable in a way that would have taken significantly longer to achieve through any other method. That moment made it very clear why this process has been a cornerstone […]
- [Splines in Mechanical Systems: Types and Applications](https://keyway-spline-broaching.com/splines-in-mechanical-systems/): Power has to go somewhere. In any machine that moves – a car, a turbine, a drill press, an industrial robot – torque has to transfer from one component to another without slipping, without wobbling, and without failing under load. That’s exactly the job that splines in mechanical systems do.  They connect shafts to hubs, gears to drives, and components to components with precision and strength that no other joining method matches. This guide covers what splines are, the main types, how they’re made, and where they get used across real engineering applications. What Are Splines in Mechanical Systems A spline […]
- [Broaching Tools: Types, Design, and Applications](https://keyway-spline-broaching.com/precision-broaching-tools/): Manufacturing precision parts is hard work. Tolerances are tight. Shapes are complex. And time on the machine costs money. That’s exactly why broaching tools exist.

Just one smooth cut that hits the spec. This guide covers everything you need to know about broaching tools – what types exist, how they’re designed, and where they get used in real manufacturing. What Are Broaching Tools A broaching tool is a long, toothed cutting tool. […]
- [Broaching Process Explained: A Beginner's Guide for Engineers](https://keyway-spline-broaching.com/broaching-process-explained/): The broaching process is a machining method that engineers get to hear of early in their careers, presumably in a setting where someone thinks they already know what it is. A component with a drawing specification that calls for a broached keyway or a broached spline can be confusing when the junior engineer is nodding along and mentally noting “I’ll look it up later”  . I recall that feeling myself. The concept isn’t complicated once someone explains it clearly but the terminology and the variety of applications can make it seem more mysterious than it actually is. At Keyway Spline Broaching, […]
- [Internal Broaching vs External Broaching: Key Differences Explained](https://keyway-spline-broaching.com/internal-broaching-vs-external-broaching/): Internal broaching vs external broaching is a comparison that comes up regularly when engineers and procurement teams are specifying machined components for the first time and trying to understand which process applies to their situation. The terminology sounds technical but the underlying distinction is straightforward once someone explains it clearly. One process cuts features inside a workpiece. The other cuts features on the outside surface.  Both use the same fundamental broaching principle but the tooling, the machine setup, and the applications are different enough that understanding each one separately helps engineers make better decisions about which to specify and when. At […]
- [Keyways in Mechanical Engineering: Everything You Need to Know](https://keyway-spline-broaching.com/keyways-in-mechanical-engineering/): If you have ever taken apart a gearbox or looked closely at a motor shaft, you have probably seen a small rectangular slot cut into it. That slot is a keyway. And that tiny groove plays a much bigger role than most people realize. Keyways in mechanical engineering are machined slots cut into a shaft or a hub – sometimes both – that hold a small metal piece called a key. That key sits between the shaft and the hub, and it is the only thing stopping them from spinning independently of each other. Without it, your gear, pulley, or sprocket […]
- [Broaching Tool Design and Its Impact on Machining Accuracy](https://keyway-spline-broaching.com/broaching-tool-design/): The design of broaching tools greatly impacts the efficiency of a machine to cut metal.
