About 18 band saw

Types of 18 band saws

The 18 bandsaw is a large power saw with teeth running on two large wheels. It is used to cut along curves and straight lines. It typically is used to cut wood, but it can also cut through different materials like metal, plastic, or foam. The two-wheel bandsaw comes in two sizes: the small 14-inch bandsaw and the large 18-inch bandsaw.

The two-wheel 18-inch band saw machine has many parts and features. Some of them are:

  • Table: A large surface usually tilted at an angle, where the material to be cut is placed.
  • Fence: A straight edge that can be clamped to an 18 inch bandsaw blade to make straight cuts.
  • Miter gauge: A device that helps the operator make angled cuts. It is in the shape of a rectangular T with a pivot that slides into a rectangular notch.
  • Blade guide: An accessory that balances and supports a blade. It holds the blade straight and prevents it from flexing, wobbling, or twisting when cutting.
  • Speed control: An option that allows the operator to increase or decrease the speed depending on the type of cut to be made.
  • Cuts: The two-wheel 18-inch bandsaw cut types are the rip and crosscut. The rip cut is the saws parallel cutting along with the grain bands. It typically uses a lower feed rate and teeth count. The crosscut refers to cutting across the grain of wood. It usually uses a higher speed and lower tooth count compared to rip cuts.

This kind of saw can also be used for resawing, which means cutting lumber with the grain to yield thinner pieces. An 18 inch resawing bandsaw is typically tall with a large throat, enabling it to cut tall pieces of wood. It also has a wide blade with fewer teeth per inch to make smoother cuts.

Specifications and Maintenance

The following are specifications for a typical 18-inch bandsaw:

  • Cutting capacity: An 18-inch bandsaw can cut materials that are up to 18 inches in width. The cutting capacity is not only dependent on the blade's width but also on the throat or distance between the blade and the saw’s frame.
  • Motor power: The motor power of an 18-inch bandsaw is between 1 and 2 horsepower. Larger sizes of bandsaws have more motor power. The motor power determines the cutting speed and ability to cut through tough materials.
  • Blade speed: Blade speed is the number of feet the blade travels in a minute. An 18-inch bandsaw can have a blade speed of 2,700 to 3,600 feet per minute. Higher blade speed is better for cutting softer materials like aluminum and plastic. Lower blade speed is better for cutting harder materials like steel.
  • Weight: An 18-inch bandsaw weighs about 800 to 1,500 pounds. The weight is dependent on the motor power and additional features, such as the material of the base and frame.

Proper maintenance of the bandsaw is necessary for optimal performance and durability. Here are some typical maintenance procedures for an 18-inch bandsaw:

  • Regular cleaning: To unclog the bandsaw of dust and debris, use a vacuum cleaner or a soft brush. Waste buildup can affect the accuracy and airflow of the saw.
  • Blade tension: Tensioning the blade and keeping it at the right levels helps to maintain its performance. Follow the manufacturer's instructions to understand the proper blade tensioning guidelines.
  • Lubrication: Lubricate the moving parts of the bandsaw, such as the guides and bearings, to enhance smooth operation. Use the recommended lubricant for the bandsaw.
  • Clean the dust ports: Cleaning the dust ports reduces waste buildup and ensures proper airflow.
  • Train users: Proper training prevents misuse, which may damage the saw or compromise its performance.

Scenarios of 18 band saws

In industrial manufacturing industries, 18 band saws are commonly used to cut a wide variety of materials, including ceramics, plastics, wood, and metal. They consolidate several cutting tasks, such as multiple cross-cuts and rip-cuts, harvesting, trimming, pad sawing, resawing, and making curved cuts. The machine's cutting blade is an important feature, with different teeth per inch (TPI) suited to specific tasks.

The 18-inch band saw is the saw machine of choice where large wood planks need to be cut into smaller pieces, boards, or strips. A wood band saw with a higher TPI is ideal for making fine cuts. A lower TPI is better for making rough cuts. Metal cutting band saws are better for making rough cuts of up to 1/4 inch thick. Additionally, a low TPI is more aggressive and works faster. However, it leaves a rougher finished edge. Higher TPI band saws cut slower but result in smoother finishes.

Materials are generally cut in a vertical direction. However, when working with large and heavy materials, an upside-down-cutting direction may work better. This is where horizontal band saws become handy. Horizontal band saws have blades that cut through materials in a horizontal direction. They are better suited for cutting thicker solid wood, metal, or plastic.

Indoor woodworking shops use 18 band saws and other band saw sizes to make furniture, such as tables, chairs, and cabinets. The industry also uses them for making wood veneers, moldings, and other customized wood products. Carpentry industries use them to cut wood planks into various sizes. Watchmaking industries cut wood, synthetic, or gemstone materials into watch cases, dials, and other components, while jewelry making industries use them to cut metal components and gemstone beads.

As operators cut through materials, 18 band saws produce a high-pitched sound that can be heard from a distance. The sound typically becomes louder when cutting harder materials like metal and gravel.

How to choose an 18 band saw

When looking to buy an 18 band saw, it is important to consider the following factors:

  • Cutting capacity: The saw's cutting capacity can be determined by its throat depth and cutting height. An 18 inch band saw machine has an approximate throat depth of 18 inches and a maximum cutting height of 12 to 13 inches. This means that the band saw can cut material that is up to 24 inches wide and up to 12 to 13 inches tall.
  • Horsepower: The horsepower of a band saw machine determines how powerful the saw machine is. It also determines whether the machine can cut through various materials or not. An 18 inch band saw machine generally has a motor horsepower of around 1.5 to 3.0 HP. This means that the machine is powerful enough to cut through hard woods and metals.
  • Cutting speed: An 18 inch band saw machine has multiple speeds. However, users can easily change the speed by using the band saw's motor pulleys. The cutting speed of an 18 inch band saw machine is around 1,000 to 3,500 RPM. This speed is suitable for cutting through various materials, including rubber, wood, and metal.
  • Construction and build: An 18 inch band saw machine consists of the saw blade, motor, wheels, frame, table, guard, guides, and rack. These parts are usually made from cast iron, steel, or aluminum. These materials are strong and durable, and they allow the band saw to cut through various tough materials with ease.
  • Dust collection: An 18 inch band saw machine comes with a built-in dust port that allows users to connect to a dust collector or vacuum. This helps to minimize the mess during the cutting operation as it collects any sawdust that is generated.

18 band saw FAQ

Q1: Why is it called a band saw?

A1: The name band saw is derived from the fact that it uses a flexible loop of a stationary band to cut materials.

Q2: What does the band saw cut?

A2: Most people are familiar with the fact that a band saw cuts wood. However, it is interesting to note that a band saw is capable of cutting through a wide variety of materials. This includes glass, metal, plastic, and ceramic. Cutting such materials requires using a heavy-duty industrial band saw machine and a specialized blade.

Q3: What are the advantages of a band saw?

A3: The unique feature of an 18 band saw is that it can cut irregular shapes. Another common advantage of all band saws is that they can make straight cuts. This includes both crosscuts and rip cuts. An 18 inch band saw is also able to make curved cuts. Curved cuts allow the user to create rounded shapes and circles. One of the biggest advantages of using a band saw is that it produces very fine cuts. The blade of a band saw is very thin, enabling it to cut with increased precision. An 18 band saw also has the ability to cut through large pieces of wood or other materials. This is due to its long blades, which can be as large as 3 to 20 feet.

Q4: Is a band saw better than a circular saw?

A4: The two most common cutting tools in workshops are band saws and circular saws. While both tools are able to cut wood, an 18 band saw is a much better option for a variety of reasons. This cutting tool produces less waste as its blade is thinner than that of a circular saw. An 18 band saw also allows users to change blades depending on the material that needs to be cut. This also enables the cutting tool to produce varying types of cuts. This includes rip cuts, crosscuts, curved cuts, and intricate cuts.
