Introduction to Broaching Machines

Must Try

In precision machining, efficient and accurate shaping of internal and external surfaces is crucial. Among the diverse array of machining processes available, broaching is a method that excels at creating complex and precisely defined profiles, stands out. Central to the success of broaching is the utilization of machines, such as those offered by Chengchun Automation Equipment Co., Ltd., which are specialized tools designed to perform this intricate task.

Principles of Operation

The fundamental function of broaching is to remove metal from a workpiece using a cutting tool. Machines that perform broaching are made to do so precisely and consistently. The basic idea behind broaching is the linear, progressive removal of material using a sequence of teeth or cutting edges.

The workpiece is secured in a fixture or clamping system within the broaching machine. As the broach is drawn or pushed through the workpiece, each tooth progressively removes a small amount of material, shaping the desired profile. The cutting teeth on the broach vary in size and shape to create the specific geometry required by the application. The process is typically categorized into two main types: linear broaching, where the broach moves linearly through the workpiece, and rotary broaching, which involves a rotating broach to generate splines or other intricate forms.

Types of Broaching Machines

Broaching machines have several variations, each tailored to specific applications and machining requirements. The primary types of broaching devices include:

Vertical Broaching Machine: This is one of the most common types. The workpiece is held stationary in a vertical broaching machine while the broach is pulled or pushed vertically through it. This type is often used for internal and external broaching operations.

Horizontal Broaching Machine: In a horizontal broaching machine, the workpiece is usually fixed to a rotary table indexed as the broach passes through it horizontally. This type is well-suited for long workpieces and can accommodate higher production rates.

Surface Broaching Machine: Surface broaching machines create flat surfaces outside a workpiece, like keyways or splines. The broach is guided horizontally across the surface of the workpiece.

Pot Broaching Machine: Pot broaching machines are designed for internal broaching of irregularly shaped holes or contours. The broach is mounted on a rotating spindle, and the workpiece is fed into it.

Continuous Chain Broaching Machine: In this type, multiple broaches are linked in a constant chain, creating more intricate profiles in a single pass.
