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.
