Automatic band saw blades are designed to cut materials at a higher rate of speed and produce more accurate cuts. An automatic band saw uses a variable-speed motor that automatically adjusts the cutting speed of the blade to match the spinning of the saw itself. This allows the operator to accurately control the depth of the cut. In addition, band saws with automatic controls also feature speed indicators and safety features that make them safe to use even by inexperienced operators. Band saws also use enclosed rotating shafts that further increase their stability and make them difficult to tip over.
A vertical band saw’s blade (2) rotates in an upright position above the saw’s spinning blades. This allows for intricate curved cuts and other shapes. However, this feature can make the verticals prone to high-speed vibration, especially when making quick curved cuts. This is why many saw manufacturers have included mechanisms that automatically stop the blades from cutting if the saw is moving at a faster rate than anticipated. For this reason, many new automatic band saws come with a stop feature that prevents excessive vibrations from occurring.
The horizontal bandsaw saw is designed for rapid material changes and angled cuts. It is similar to the vertical in many ways, including its ability to cut curved shapes with accuracy. The main difference is that the horizontal band has a separate blade and motor that are attached directly to the machine. Unlike the vertical, an automatic band saw can accommodate larger cutting areas because of the extra space available on both sides of the blade. This means that you may need to buy a machine that has more than one blade and motor to accommodate the various cutting requirements of your business.
There are two main types of controls used on the saw: mechanical and digital. A manual control is usually found on a horizontal band saw and uses a rubber or plastic grip to maintain a fixed cutting thickness. An automatic band saw, by contrast, uses a series of electronic sensors to sense material movement and apply the appropriate cutting speed. Because it uses a combination of manual and electronic controls, this saw type must be properly maintained and serviced to ensure optimal performance. Regular cleaning of the cutting surface and blade and alignment, as well as checking for wear and damage, will help the machine to perform at its peak for years to come. Lubrication and wheel alignment also help to ensure maximum performance.
Similar to the vertical, there are two main types of semi-automatic band saws: fully automatic and semi-automatic band saws with a kickback option. Firing one continuous stroke without having to kick the machine back is a great advantage on many horizontal machines, which makes them highly desirable when working with large materials such as logs or sheets of plywood. However, kickbacks can cause a slight amount of damage to softer and more flexible materials and may make smoother cuts difficult.
When shopping for a new saw, you should consider the various options available for the blade, as well as the different blade types and teeth shapes. There are both straight and angled blades available, and depending on your application, you may need one of each. Some saws use only crosscutting teeth, while others employ twin or crosscutting teeth that cut both inside and outside edges. Depending on the job you’ll be doing, you’ll need to look at the size of the blade and its crown, as well as whether or not you want a sharp blade with a double edge. For lighter jobs, a single edged blade offers the best balance between power and ease of use.
