An hydraulic auto feed bandsaw is a large saw that uses a continuously rotating band blade, or ribbon blade, running under coolant, to cut bars, pipe, and structural steel into desired lengths. The original bandsaw, patented by William Newburry in 1808 was designed to cut wood logs. Through history, bandsaws in timber sawmills have been run manually, by wind, and by water. Today, almost all bandsaws are run by electric motors.
In manufacturing, a bandsaw is often one of the first machines in a long string of operations to take raw material and turn it into a finished part. Bandsaws can cut a variety of materials including steel, aluminum, stainless steel, and more. Depending on the capacity of the saw being used, bandsaws can cut very large pieces of material as well. Using a coolant pump to constantly bathe the cutting service in fluid, the temperate of the blade is always minimized, keeping it from overheating, extending blade life, and allowing for very fast cuts and high output. A cooled blade, combined with automatic feed, means a hydraulic auto feed bandsaw can cut parts continuously for long durations with minimal downtime, and very little oversight required of the operator.
With bar and tubing coming in various lengths, shapes, and sizes, there are a variety of parts that can begin their life on a bandsaw. Some examples of parts that must first be cut into segments include shafts, gear blanks, wheels, collars, bearings, and more. There is no better method for producing large volumes of part blanks. After being cut to the desired length, a part will often move on to other machining processes such as turning, milling, or threading. In some instances where bar is purchased to a pre-finished specification, cutting it to length may be the only operation needed, and will yield the finished part.
