Blind keyways are keyways machined inside a bore that does not pass completely through the part. Because the tool cannot exit out the back of the hole, blind keyways require proper planning, relief, and programming to avoid insert damage and to produce a clean, consistent slot. CNC broaching makes it

Is CNC Broaching Bad for Your Mill or Lathe?
It’s a common question among machinists new to broaching on CNC machines: will broaching damage my mill or lathe? The concern is understandable. Traditional broaching is known for heavy cutting forces and specialized equipment, so the idea of broaching inside a CNC can sound risky. The truth is that when
What is Spline Broaching?
Spline broaching is a machining process used to create a series of grooves or teeth, known as splines, on the inside of a bore or along the outside of a shaft. These splines form a drive connection between two mating parts, allowing torque to be transmitted while maintaining alignment. The
What is Keyway Broaching?
Keyway broaching is a machining process used to cut a slot, called a keyway, inside a bore. A keyway is a groove that allows a key to fit between a shaft and a mating part such as a gear, pulley, or coupling. This slot-and-key connection locks components together, transmitting torque
What is Broaching?
Broaching is a machining process used to cut internal or external shapes by pushing or pulling a specially designed tool called a broach across a workpiece. Unlike traditional cutting tools that may require multiple passes or secondary operations, a broach tool removes material in a single, progressive motion. Each tooth
How to Optimize Broach Depth of Cut to Extend Tool Life
CNC Broach Tools G-code Program Generator V2 Broaching is one of the most efficient processes for creating precise internal features such as keyways and splines. Yet, tool life in broaching often seems unpredictable, with many shops relying on trial-and-error settings that can lead to premature wear or poor finishes. The
How to Broach Tapered Keyways in a CNC Machine
Tapered keyways present unique challenges when it comes to broaching on a CNC machine. Unlike straight keyways, the taper requires careful planning to avoid insert interference, depth errors, or tool damage. At CNC Broach Tools, we want to outline the best practices to help machinists achieve clean, accurate results while
Precision Matters: The Correct Way to Program Radial Depth
Introduction Achieving precision in keyway broaching is essential for optimal tool performance and longevity. At CNC Broach Tools, we’ve identified a common pitfall: misinterpreting the radial depth input in our CNC Broach G-Code Program Generator. This guide aims to clarify the correct approach to programming radial depth, ensuring efficient and
What is Keyway Broaching? | The Ultimate Guide
Introduction Keyway broaching is a precise machining process used to create keyways—slots that accommodate keys in mechanical power transmission components like gears, pulleys, and shafts. This technique ensures secure mechanical connections and prevents slippage between components. At CNC Broach Tools, we specialize in carbide broaching tools that allow machinists to
Why CNC Broach Tools Online Program Generator Beats Machine-Specific Canned Cycles
Introduction: CNC Broach Tools has always strived to provide the best solutions for broaching applications, including our innovative online program generator. While machine-specific canned cycles, such as Haas G156 or Okuma G190, are commonly used for CNC operations, there are significant reasons why our customers can benefit more by utilizing
