Useful Information About A Broaching Machine
Broaching really just means working with metal or other solid materials. So it stands to reason that a broaching machine uses modern technology to shape and cut metal or other products. This unique machine has a broach which is a tool that produces unusual shapes. It is efficient and precise and finishes a desired surface in one pass. The surface can be flat, circular or non-circular. Most broaches are relatively inexpensive and are highly desirable by many companies making certain types of solid-material products.
The teeth on a broach start out small and gradually increase in size. A broach resembles a standard saw and is made up of three specific parts. One section is used for roughing and the other two sections do the pre-finishing and final-finishing work. The feed comes built right into the broaching tool. Any surface that is machined is the inverse of the broach’s profile. As the teeth rise on the broach, the amount of material removed is increased as is the size of the chips. There is no particular skill needed to actually operate the broach because everything is built right in.
Broaching is an excellent way to machine surfaces and shapes using high intensity workpieces. Each individual broach cuts one particular shape so it must be made to fit the workpiece or the workpiece must be set to standard breach specifications. High volume workpieces can be expensive, costing as much as $30,000.00.
The speed of broaches is variable, ranging between 20 and 120 surface feet per minute. The cycle time is short and includes the return stroke, handling of the broach itself and loading and unloading the workpiece. When broaching is used, there can’t be any obstructions over the machined surface, there cannot be any curving in the various planes and the workpiece must be durable and strong.
A broaching machine is best used on soft materials. Brass, bronze, wood, plastic and aluminum are just some of the materials that work well with broaching. Certain types of steel can also be broached. Today’s technology has made broaching a useful and ideal way to shape and work with a variety of solid materials. Many companies throughout the world use broaching as a way to enhance their business production processes.
