An Overview of the Types of Broaching Machines

Must Try

Broaching is an extremely precise machining process that can create distinct features and shapes in different materials, including plastic, metal, and composites. Broaching involves using a machine to pull or push an abrasive tool through the material, removing tiny amounts of material with each move. There are many kinds of broaching equipment that each have its features and mhtspace advantages. 

In this article, we’ll explain the various types of broaching equipment, how they function, and what advantages they provide in various industrial applications. If you’re an engineer, machinist, or just curious about manufacturing technology, this guide will give useful insights into the Broaching machine world.

Types of Broaching Machine

The following are the different types of broaching machines.

  • Vertical broaching machines
  • Horizontal broaching machine
  • Continuous broaching machine
  • Surface broaching machines

Broaching machines are among the most basic of machine tools. Broaching machines comprise a broaching tool, an adjustable work-holding fixture, a motor, and a frame for support. While the components are small, many designs can be made.

There are two main broaching types Vertical and horizontal.

Alongside these basic models, there are also specific and continuous-operating machines. The vertical and horizontal versions of machines come with at least one or two rams based on the demand for production.

Dual-ram models ensure that one ram is on one side of the cut stroke and the other is on the return stroke. The return stroke will be completed quickly to speed up the process that can be utilized to load and unload the machine.

Broaching machines typically pull in or push the broach through or over a piece of work secured in an encasement. In some machines, the workpiece can be moved over the broach, which is held to its location. Most broaching machines are controlled hydraulically to ensure an even, smooth cutting process.

Vertical Broaching Machine

The vertical varieties can be found in push or pull types. The push type is the most well-known. Vertical broaching machines are depicted in the picture.

Vertical automatic broaching machines are employed in various operations because they make it easy to transfer work between machines. Three types of vertical machines are available: pull-down or pull-up, and push-down; the last version is the most well-liked. Vertical machines need an operator’s platform or pit and require less area than horizontal models.

Continuous Broaching Machine

For the mass production of small components, The highly efficient continuous-broaching method is employed for horizontal or rotary continuous-broaching equipment.

In the broaching machines that are rotary continuous broaching machines, the workpiece is placed on a table that rotates constantly. During the operation, the broach remains stationary.

The workpieces are moved in horizontal continuous broaching machines as an indefinite chain transports them. They are then loaded onto fixtures to hold the workpieces that are attached to the chain, which is constantly moving. While the operation is in progress, the broach stays stationary, just like prior. The machines are designed to broach small parts.

Horizontal Broaching Machine

Most horizontal machines are a type of pull. They can be employed for external or internal broaching, though internal work is the most interbiography popular.

Horizontal broaching machines are illustrated in the figure. It comprises the bed or the base that is a little more than double the size of the stroke as well as a broach pilot and the drive mechanism that pulls the broach.

Surface Broaching Machine

In surface broaching machines, broaching tools are attached to rams and pushed over the workpiece in a straight line following guideways. For some surface broaching devices, the ram moves horizontally, while on other machines ram is vertical. When two rams are utilized, this machine is called a duplex broach.
