Introduction to Spline Gages

What are the most common types of Spline Gages?   There are 3 main categories of spline gages (also spelled “gauges”) to check splined components: Functional Gages are commonly called Go and No Go gages. They include Plug – used to check internal splines – and Ring – used to check external splines. These can […]

Understanding Broach Tool Design

The broach tool design diagram below shows the general geometry of a hole broach. Note that “P” represents the pitch, “nr” is the number of roughing teeth, “ns” is the number of semi-finishing teeth, and “nf” is the number of finishing teeth. The broach tool design includes three sections: roughing, semi-finishing and finishing. The broach […]

Introduction to Broaching

What is Broaching? Broaching is a machining process that uses a toothed tool, called a broach, to remove material from a workpiece. There are two main types of broaching: linear and rotary. In linear broaching, which is the more common process, the broach is run directly against a surface of the workpiece to achieve the cut. Linear broaches are used in a broaching […]

Types of Broach Tools

What are the different types of Broach Tools? A broach tool (usually called, simply, a broach) is similarly shaped to a long drill bit or saw, except the height of the teeth increases over the length of the tool. The desired outcome of the broaching process determines the type of broach that will be used […]
