Reciprocating Saws
A reciprocating saw, derived from the word reciprocate, meaning to move backward and forward in a straight line, is a type of saw in which the cutting action is achieved through a push and pull reciprocating motion of the blade. Reciprocating saws cut through just about everything short of a rock. It’s the go-to tool for remodeling and demolition. With a recip saw you can cut through lumber even if it’s embedded with nails. It can also cut all common forms of metal: steel, aluminum, copper, and cast iron. But to get the most out of your tool, you’ll need …
Reciprocating versus Bandsaw
Bandsaw machines are different than reciprocating saws when it comes to the cutting process motion. Compared to a bandsaw machine, which forms a continuous loop of band using a bandsaw blade to perform the cut, the reciprocating saw’s cutting action is achieved through a push/pull reciprocating blade motion. The reciprocating saw is similar to a jigsaw. The user rests his foot against the cutting surface in order to counter the blade’s tendency to push away from or pull towards the cut as the blade travels through its cycle. Most bandsaw machines are found in job shops or any shops that deal with metal cutting …
Reciprocating Saws
Back in 1951, The Milwaukee Electric Tool Corp manufactured the first reciprocating saw and is commonly referred to as a Sawzall. The Sawzall has a long D-shaped handle and requires both hands to operate. It weighs around 10 lbs, which helps to minimize vibration and provide improved grip. The Sawzall normally has a variable speed trigger and/or controller for simple change of speed if needed. The term reciprocating saw (oscillating saw) applies to any saw that cuts using a back & forth motion. These include the jigsaw, the scroll saw, the saber saw, and the rotary reciprocating saw. The reciprocating saw operates using different blade types: bi-metal, …
The Chop Saw
A chop saw is a lightweight circular saw mounted on a spring-loaded pivoting arm, and is supported by a metal base. A stationary power tool that cuts material with a downward, chopping motion. The chop saw (drop saw) is a Miter or Abrasive saw, although both are entirely distinct classes of power tool. The Miter Saw A miter saw is used to make quick, accurate crosscuts in a work piece and at a selected angle. Common uses include framing operations and mold cutting. Most miter saws are relatively small and portable, with common blade sizes ranging from eight to twelve inches. Power …
Materials Handling Affects Cutting Process
Materials handling is the process of loading, unloading, staging, and transferring of cutting materials. Different types of materials handling systems on bandsaw machines include power in and out feed roller conveyors, to cross- transfer systems, and the automated cut-to-weight systems. There are also sorting and ejection units. Some manufacturers will allow users to modify or upgrade materials handling systems on the bandsaw depending on the customers production needs. A solid materials handling system is important for any sawing operation: especially for fabricators that deal with bundles and large profiles. The primary use of a materials handling system is to assure …
Band Tension and Cutting Performance
Saw blade tension is a technical term used to describe how tight the bandsaw blade is on a bandsaw and is expressed in Pound per Square Inch ( PSI). The amount of tension applied will depend on blade thickness and width, and wheel diameter. Various methods are used to set the correct blade tension, from gauge use to blade plucking not unlike that of a guitar string. Tension can be adjusted by a gauge indicator on the bandsaw. It will indicate the amount of tension required based on the width of the saw blade. Using a tension meter will assure the most accurate …
About Bandsaw Worm Gears
Worm gears are used when large gear reductions are needed. The set-up allows the user to determine rotational speed and also allows for higher torque to be transmitted. Many worm gears have an interesting property that no other gear set has: the worm can easily turn the gear, but the gear cannot turn the worm. This is because the worm angle is so shallow that when the gear tries to spin it, the friction between the gear and the worm holds the worm in place. The three different types of worm gear are: No throat – a straight worm without a groove …
