Ohio Broach: All the basics about its professional broaching techniques

Ohio Broach offers internal and external broaching.

For almost 65 years, The Ohio Broach & Machine Company has been a leader in virtually every kind of professional broaching service that a customer could need. But what is broaching, exactly? This question merits a detailed answer to do full justice to the range of services that the company provides.

On a general note, broaching is a valued, important machining technique that offers a unique level of efficiency and precision.

Often used in precision machining

Broaching is a process of removing material from metal, usually less than Rc 30 in hardness, with a toothed tool known as a broach. Similar to a saw, the tool has teeth that increase in height over its length. This builds “feed” into the broach. Each of the different sections works for a different broaching technique (such as roughing, semi-finishing, or finishing) by varying the teeth’s height differences.

Professional broaching is often used in precision machining and particularly suitable for unusual metal shapes. Common examples of broached surfaces: serrations, splines, keyways, and flat surfaces. Frequently processed work pieces include castings, forgings, screw-machine parts, and stampings.

Two main types of broaching are available from Ohio Broach – internal and external broaching. Internal broaching involves running the broach linearly through a pilot hole in the piece to create a cut in a pull- or push-type broaching machine, while external broaching is the method of running a broach linearly against the piece’s surface to effect a cut, typically in a vertical surface broaching machine. Each technique needs only one pass to make the cut, and both yield results with more precision and higher speed than do most other machining processes.

Ohio Broach provides almost any specific professional broaching service that exists, and it manufactures and sells broaching machines for private users to do their own broaching work. But this is not all – the company offers sharpening, repair, and reconditioning services to keep machines and tools in top condition. Through production broaching, the Ohio Broach team uses its vast talents and experience to machine a wide range of parts and shapes.
