What Are The Advantages And Disadvantages Of Broaching?

Broaching is a machining procedure that uses a tool with teeth known as a broach to take the material from an object. By inserting the tool into the object’s opening, the teeth are used to cut the material surrounding the hole. Broaching is a technique that has advantages and disadvantages when compared to other methods for cutting. Let’s take a look at the advantages and disadvantages of broaching.

What is broaching, and what are the advantages of it?

Broaching is a process of machining that uses a sharp, hardened, toothed tool to remove material from the workpiece in a continuous, consistent, and precise way. Broaching is a process that uses an instrument with teeth of different sizes that precisely remove a specific amount of material for each move over the piece.

When is it appropriate to use broaching?

Broaching is a type of machining that creates various shapes. Broaching uses a tool equipped with cutting teeth to take the material from a piece of work. Broaching is a method to create external or internal designs and is commonly used to make keyways, splines, and slots. 

Broaching has the advantage that it allows you to create intricate designs that are difficult or impossible to make with other machining methods. Additionally, broaching is exceptionally rapid and efficient, making it a desirable choice for large-scale production runs.

One of the crucial elements of every machine shop is broaching equipment. It is used for various external and internal machining tasks; Chengchun hydraulic broaching machines can complete complex tasks with speed and accuracy.

However, it has its negatives. Broaching is generally only suitable for small components and requires specialized equipment that is costly to buy and maintain. Therefore, companies must carefully evaluate how broaching might be the most practical alternative before investing in the necessary equipment.

The advantages of broaching :

  • High production rate, much greater than planing, milling, and boring.
  • Precision in dimensional and shape and surface finish of the product.
  • The roughing and the finishing process is done with one stroke using this same cutting tool.
  • Only one motion is required for cutting, therefore construction, design operation, and control are all the same.
  • Very economical and suitable for mass production.
  • Expertise isn’t required.
  • Remarkable finished face.
  • Short cycle times with high precision.
  • It is not difficult for a broaching procedure.
  • Broaching is a method of external or internal finishing of surfaces.
  • An accuracy of +-0.0075 millimeters and an average finish of 0.8 microns are achievable through this method.
  • Cutting fluid can be easily used where it is the most effective since the broach is able to draw the fluid in the cut.

The disadvantages of broaching.

  • The only way to the machine is through the holes. Only on surfaces can be machined.
  • Useful only for small cuts.
  • The speed of cutting cannot be very fast.
  • Damages or defects within the broach can seriously affect the quality of the product.
  • The design, manufacturing, and repair of broaches are complicated and costly.
  • A different broach needs to be purchased and utilized when the dimensions or shape of the work change.
  • Only if the production volume is huge.
  • A huge workpiece should not be sprayed with broaching.
  • High-end tool costs.
  • Broaching cannot be used to remove an enormous amount of inventory.
  • The parts to be cut must be able to support rigidity and be able to withstand the pressures generated when cutting.
