The biggest draw of the broaching process is the custom broach fabrication process, in which your manufacturing can fabricate a broach tool with your exact specifications and application in mind in order to create the best possible final product for you.
In order to find the best possible manufacturer you will need to assess your application and determine your needs and wants, from there you will consult manufacturers with broaching capabilities until you find a company that either specializes in your application or has the years of experience and knowledge to offer you custom broach fabrication.
There are a number of different types of broaches that can be made; these are typically categorized by their use, purpose, motion, construction, or simply by their function. The overall broaching process can be a bit costly, so it is more commonly used within large production runs or runs where a high quantity of parts is needed in order to justify the custom of the initial broach fabrication..
In order to determine which type of broach you will need, you must look at your application and either provide a blue print to the manufacturer for them to follow or be very precise in how you outline your requirements. Broaches can be broken up into two main categories, surface broaches and internal broaches.
Surface broaches have a variety of subcategories from the slab broach which cuts flat surfaces to the straddle broach which is basically two slab broaches that cut a parallel surface.
Internal broaches also have a variety of subcategories such as modular broaches which are used for larger internal broaching applications to cut-and-recut broaches which are typically used to cut thin-walled objects.
Whatever your application may be, working with the right manufacturer is the best way to ensure that you receive the highest quality final product.
Remember that the highest cost comes from the actual broach fabrication process so verify that your production is a large enough quantity to justify the broaching and broach fabrication process.
