Vertical band Saw
DESCRIPTION
This EXCEL Coventry Vertical Band saw has a moving band saw blade fixed in a vertical position while the material to be cut is fed into the blade by a table. There are stoppers provided to cut parallel pieces. Different grades of blades are available based on the material to be cut. A vertical band saw, also called a contour saw, keeps the blade's path stationary while the work piece is moved across it. This type of saw can be used to cut out complex shapes and angles. The part may be fed into the blade manually or with a power assist mechanism. This type of metal-cutting band saw is often equipped with a built-in blade welder. This not only allows the operator to repair broken blades or fabricate new blades quickly, but also allows for the blade to be purposely cut, routed through the center of a part, and re-welded in order to make interior cuts. These saws are often fitted with a built-in air blower to cool the blade and to blow chips away from the cut area giving the operator a clear view of the work. This type of saw is also built in a woodworking version.

Horizontal band saw
DESCRIPTION
his EXCEL PBS 225 band saw cuts intermediate-size work pieces, with an adjustable worktable as well as an auxiliary worktable useful for handling larger work pieces. The worktable is 24” by 20” and can cut material up to 13” tall. Its adjustable blade feed pressure supplies up to 60 lbs. of cutting pressure and is able to make compound angle cuts. The rate of feed is controlled by a hydraulic resistance. The cutting blade is rotating and the work is held stationary. Typical band speeds range from 40 feet (12 meters) per minute to 5,000 feet (1,500 meters) per minute. Metal-cutting band saws are usually equipped with brushes or brush wheels to prevent chips from becoming stuck in between the blade's teeth. Systems which cool the blade are also common equipment on metal-cutting bandsaws. The coolant washes away chips and keeps the blade cool and lubricated. Small horizontal bandsaws typically employ a gravity feed alone, retarded to an adjustable degree by a coil spring; on industrial models, the rate of descent is usually controlled by a hydraulic cylinder bleeding through an adjustable valve. When the saw is set up for a cut, the operator raises the saw, positions the material to be cut underneath the blade, and then turns on the saw. The blade slowly descends into the material, cutting it as the band blade moves. When the cut is complete, a switch is tripped and the saw automatically turns off. Both Round, Square, rectangle and even irregular shapes of material can be cut in to pieces.

ARC Welding Machine
DESCRIPTION
This machine is an ARC Welding machine is used to joined metal with the help of an electric arc. Welding is a fabrication process that joins materials with or without a filler material. Welding equipment includes MIG, TIG, and STICK, Gas Welding as well as Oxy-acetylene and plasma cutting. The principles can be taught to students but hands-on practice develops welding skills. Welding machine is used to joint metal permanently. Welding is a fabrication or sculptural process that joins materials, usually metals by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. In addition to melting the base metal, a filter material is often added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that can be as strong or even stronger, than the base material. Pressure may also be used in conjunction with heat, or by itself, to produce a weld.

Orbital Welding Machine
DESCRIPTION
Orbital welding machine is used to weld small tubes by GTAW (Gas Tungsten Arc Welding) application, where a tungsten electrode creates an arc and rotates around a tube and make a weld joint.
