What is the main advantage of broaching over the shaping process?

Broaching is the machining process that is specially designed for multi-point cutting tools. That is called broach. The broaching process is widespread in automobile industries that help in machining of gears, various machine holes, keyways, splines, etc. There are many broaching machine manufacturers in India that are providing the most convenient machines for their customers.

A horizontal broaching machine can smoothly work on soft metals like aluminum, copper alloys, plastic, polymers, wood, etc. It is suitable for smooth metals and can also frame hard material like titanium, which may blunt the machine’s teeth.

 

Why broaching process is more preferred than the shaping process?

 

This device movement is used to remove any material from the workpiece and gives a desired shape of the material. Broaching machines consist of numerous progressive teeth, so broaching becomes more reliable and accurate than the shaping process. The broaching operations are usually used for the machining of gears, holes, splines, keyways. Due to this feature, they have become economically helpful for the different industries to produce irregular long holes.

 

Although the broaching process offers multiple advantages than convenience. These advantages are the following:

  1. The broaching process offers a high production rate at a low cycle. It makes the broaching faster as compared to the cutting operation of other materials.
  2. The price per piece is also lower in broaching process.
  3. Many operations are replaced by broaching due to its high functionality. As one stroke of broaching teeth can perform rough-cutting as well as a finishing process.
  4. The operation and application of broaching machine are handy and straightforward.
  5. It maintains the constant temperature of the workpiece that avoids the error that may cause due to thermal stress.
  6. Broaching of any material can be used for internal as well as external cutting operations.
  7. The life span of broaching material is higher than shaping processed material because one tooth of broaching machine requires only one tiny cut in a single operation.
  8. Broaching offers excellent surface finishing with high dimension accuracy and close tolerance.
  9. In this process, the force of cutting is always applicable in the clamping direction that assists in holding or clamping the workpiece at an accurate position.
  10. The broaching process is quite simple as it does not require any high demanding skill for the workers.
  11. The cutting of fluids is more effortless and effective.

 

Such astonishing benefits of broaching are enough to prefer broaching over the shaping process for the users. There are different types of broaching machines, like vertical broaching machine are available in the market. You can buy any of them from the most trusted supplier of broaching machines that is Crane Bel.

 

Broaching Machine: Types, Operations & Advantages

Most industries widely use broaching machines as sharp, hard, toothed tools to remove materials from a workpiece consistently, continuously, and accurately. These machines are used to cut the workpiece in a particular size and shape.

There are various types of vertical broaching machines available based on a portion of the workpiece that will be surfaced.

 

Types of Broaching Machines

 

  • Horizontal Broaching Machine

Horizontal broaching machine consists of a bed or a base almost double the length of broaching stroke in which the broach pilot and the drive mechanism for pulling the broach. These are used to broach keyways, splines, slots, round holes, and other shapes or contours.

 

  • Vertical Broaching Machine

Vertical broaching machines are available in two types: a push or pull in which push type is more popular. Vertical devices are used to operate a platform or a pit and economical of floor space in comparison to horizontal type. At the same time, modern vertical broaches are used for hydraulic and electro-mechanical drives.

 

  • Surface Broaching Machines

These broaching tools are attached to specific or rams forced in a linear path and past piece work. Broaching machines travels on the workpiece horizontally, and the other one travels vertically. At this moment, the device is called a duplex broach.

 

  • Continuous Broaching Machines 

This broaching machine is best to use for mass production and is highly productive with continuous broaching methods on rotary or horizontal continuous broaching methods.

 

  • Operations by Broaching Machines

It is applied to various internal as well as external surfaces to get round or irregular shaped holes. Many types of surfaces, such as spline holes, are only machined presently through broaching.

 

Various operations are held on broaching as some are completed in one pass, while some are arranged for repeated cuts to get the desired design of broaches.

Broaching machines can broach the teeth of gear or spline together in few seconds. A simple broad is made to cut one or few tooth spaces. With the first pass, the gear blank is indexed until all the teeth are cut off. After all the teeth are finished, successive passes are made.

 

Exclusive Advantages

  • Enhance the production rate of the products.
  • Ensure high-class finish and accuracy on the surface.
  • One pass of tools can do rough finishing cuts at one time.
  • It is used for external as well as internal use.
  • Broaching machines can cut the workpiece in any shape or design.
  • One can apply the cutting fluid on the effective area as the broach tends to cut more efficiently in the liquid.

 

Conclusion 

Crane bel is one of the best and largest broaching machine manufacturers in India, the largest manufacturer of broaching machines. As the process of broaching offers exceptional surface finishes and multi-dimensional accuracy.
