2. First of all, the rate of production is extremely high because broaching is such an efficient process, and is very repeatable. The advantage of performing this operation is that it almost always costs less, because it eliminates a secondary operation on another machine. This eliminates subsequent operations and results in savings of time and money. Advantages of broaching High production rate and low cycle. Broaches are referred to as multiple-point linear-travel cutting tools and are used to produce flat, circular, and even extremely intricate profiles, as seen from a section perpendicular to the tool travel. Broaching Machine Specialties has designed and built dozens of broaching machines for hand tool companies all over the United States. When rotary continuous broaching machines are used, a work piece would be loaded on a table which is continuously rotating, while the broach itself remains fixed. Only certain workpieces are suitable; There cannot be any obstruction in the path of the tool. There is also a good deal of versatility associated with the broaching process because it can be used for both internal and external surface finishing. c) Roughing and finishing cuts are completed in one pass of the tool. Steels, cast irons, bronzes, brasses， aluminum, and a broad range of other materials are successfully broached with proper broach design and setup conditions. Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks). In most cases, all that’s necessary is to have the operator load and unload a given work piece, and the broaching machine will do everything else. It’s also true that the pieces you’re working with don’t really need to be designed for standard broach geometry, because broaching can be custom-designed to accommodate almost any kind of geometry when unique shapes are required. That economy is in effect whether you’re machining a single piece or 1,000 units. Horizontal continuous broaching machines call for the work pieces to move as they are carried along by a tracked chain. Broaching. There are several different broaching process methods that are commonly used in business today. High productivity rates; Close tolerances; Good Finishes; Economical Operation (for many applications) Disadvantages. In the era of competition, continuous improvement of process and procedure is a must. This is an advantage in close-fitting reciprocating parts, where radial lines may be objectionable because the high spots tend to wear rapidly. It’s typical to achieve a level of accuracy which has an extremely low tolerance of error, as well as a finish which is just as precise. Because broaching can do all this in one pass, it’s not only very efficient, but it’s a cost-saving approach, especially when implemented for applications done in high-volume. Materials Suited for Broaching. The operation performed on a shaper is a) Machining horizontal surface b) Machining vertical surface c) Machining angular surface d) All of these. This method is mostly used for broaching a whole slew of similar work pieces all at once. There are two main types of broaching: linear and rotary. d) All of the above . In this article we will discuss about broaching operation Principle, tools, types, advantages and disadvantages. An advantage of this design is that it eliminates the tendency for parts to move sideways in the workholding fixtures during broaching. Needs only one motion of cutting, so design, construction, operation and control are simpler. Vertical broaching machines can be used in a number of operations because it’s so easy to pass work along between several machines. A vertical broaching machine requires an operator platform but does not need a lot of floor space, so it’s good in tight areas. Tapered holes cannot be broached Another advantage of broaching is that both the rough cut and the finished cut will be completed with a single pass of the machine, and this not only saves time but money as well because it’s not necessary to undergo repeated passes. There is two type of broaching, linear broaching and rotary broaching. The advantage of a broaching operation is that A. The advantage of performing this operation is that it almost always costs less, because it eliminates a secondary operation on another machine. The broaching process used will depend on whether you’re using an internal broach or a surface broach.

A vertical broaching machine might be used in either a pull broaching process or in push broaching, although push broaching is more popular. One of the major advantages of using this operation in various industries is its ability to give better surface finish and good accuracy with mass production rate. High accuracy and a high class of surface finish are possible. 8.15 Broaching. Linear broaches are used in a broaching machine, which is also sometimes shortened to broach. These machines can be categorized on the basis of different criterion as described below. Rotary broaching is a rapid machining method that cuts shapes into or onto a workpiece. Following are the features and advantages of the broaching: The rate of production is very high. Broaching operation is faster than other metal cutting operation. As an example, you could have the broaching tool staying stationary with the workpiece being moved against it. The set-up essentially consists of a spinning machine similar to a centre lathe.
