A Simple Explanation Of Automatic Band Saw Operation

An automatic band saw is a machine saw that automatically functions in a horizontal direction, with the blades perpendicular to the work surface. A vertical band saw blade (2) rotates in an upright position and stays stationary while the material to be sliced rises into the blade. This enables for intricate curved cuts and shapes to be produced. When fully progressed, this saw can cut over 100 slices per minute!

The first step to fully utilizing an automatic band saw is to purchase and accurately adjust the saw’s tension. Since automatic saws feature heavy duty tension, the tension must be tightly in order to prevent damage to the motor and the blade if the motor is pulled too tight. While tightening the tension, the blades will rotate. Loosen the setting just enough that the blades will not cut off the material being cut. If the saw is operating at too high of a speed, it could lead to injury, especially when attempting complex angled cuts. When attempting to manually tighten the tension, it is wise to use a wrench on the saw’s control box.

After the tension has been properly adjusted, it is time to clean the saw. This is done by removing the blades and taking the old cutting fluid and replacing it with new fluid. It is also wise to replace the cutting brush. The new automatic bandsaw brush will help remove any dust or dirt particles that may have stuck to the old brushes during the cleaning process.

The next step to fully utilizing an automatic band saw is to properly set the cutting speed. Setting the cutting speed too slow can cause the machine to cut too many turns in each revolution of the saw blade, making the material cut too slowly and resulting in poor cuts. Conversely, setting the cutting speed to fast can result in excessive noise and excessive waste of electricity. Excessive noise can also distract other people in the vicinity. Keeping in mind that sound amplifies the potential for damage, it is best to only use a low setting of cutting speed when cutting large pieces of wood.

Next, the band saw must be allowed to rotate freely on its axis, which is achieved when the fence of the saw is placed parallel to the vertical and horizontal axis of the machine. The combination of circular saw blades and horizontal blades creates an arbor which directs the saw’s crosscutting direction. When the arbor is aligned with the blade’s crosscutting direction, the cutting direction is true. It is important to note that when cutting circular materials, it is important to start the cut with the blade at the bottom and to assume full width at the end of the cut, rather than cutting from the middle.

Once the saw blade is at the desired cutting depth, the band saw will automatically lock to the position and remain stationary until the material to be cut is removed. At this time, the saw will rapidly decrease its cutting speed, as per manufacturer’s instructions, to match the decrease in material it is currently working with. It is at this point that the operator will need to manually control the saw to alter the cutting depth and angle of the blade, if necessary. By using the manual adjusting mechanism, the operator can determine how deep and how far away from the edge he wants the band saw to cut. In addition to using the manual adjustment mechanism, controlled electronically, the operator may also adjust the fence and other mechanisms of the band saw.
