The first step in the manufacturing process of any fastener, regardless of its final configuration, is cutting the bolt to length. Raw material in the form of round bar ranging from 12′ to 40′ in length is either saw cut or sheared.
Band saws use saw blades to cut through the steel round bar. On the other hand, shearing equipment functions like a guillotine, “chopping” the raw material. During the shearing operation, the material is automatically run against a stop and then sheared to length. This quick process is an extremely efficient method of cutting material and will translate into more cost effective product produced in a more time efficient manner.
Portland Bolt implements systems to ensure heat lot traceability on all raw material brought into the facility and heat numbers are recorded when the material is cut. This insures cutting of correct materials and proper documentation of the finished product.
|2||Peddinghaus Shears||Capable of shearing up to, and including, 2" diameter round bar with a maximum length of 100".|
|2||Hyd-Mech Band saws||Band saws are used for cutting large diameter round bar and pipe sleeves. Certain grades of heat treated round bar, small quantities, lengths which exceed shearing limitations, and headed blanks will be cut using band saws.|
