Bandsaw Chips Check
Fabricating shops use bandsaw machines to cut a variety of materials including beams, structurals, heavy wall tubing, stainless steel, tool steels , pipes, and tubes. Bandsaw operators incorporate an effective sawing operation by first choosing the right bandsaw blade, and then performing a blade break in procedure. These are then followed by properly setting the machine, using the correct feed rate for the material, running the saw blade at the recommended speed rate, and cutting with or without coolant (depending on the materials). But there is one aspect that most bandsaw operators do overlook, and that is to check the shavings …
Feed Mechanisms
The bandsaw feed mechanism aids in proper machine usage, allowing for an easy and productive cutting procedure with positive end results. Blade life preservation is another aspect. Gravity feed saws behave as their name implies and rely on their own weight. The cutting force can be adjusted by a movable counterbalancing weight, a screw-thread coil spring adjustment, or by a hydraulic or pneumatic damper or speed control valve. A damper won’t force the blade down but instead limits the fall speed, preventing excessive feed on thin or soft parts. Hydraulic feed saws use a positive pressure hydraulic piston to move …
Proper Blade Break-In Procedure
Proper bandsaw blade break-in means achievement of a smooth operation via perfectly cut materials, resulting in a successful output — accountability at its easiest and best. One aspect of an operator’s responsibility to professional accountability in the sawing industry is to achieve proper installation and maintain full function of bandsaw blades. Assuring proper bandsaw blade break-in is crucial to the industry, and some bandsaw operators will agree that the best advice to heed is a relatively simple mind-game of sorts — to think of the saw blade as a new pencil with a sharp tip. Too much pressure and the tip breaks, and with extended use, …
How to Prolong Bandsaw Blade Life
The proper use and daily maintenance of bandsaw blades will help to prolong bandsaw blade life and provide effective output for the duration of the blade. With time and usage, bandsaw blades start to deteriorate. Stripped teeth, band breakage, crooked cuts, premature cutting of teeth, and rough cuts occur with a dull, worn-out blade. To help prolong bandsaw blade life, there are simple and daily steps to take that will guarantee prolonged bandsaw blade life and achieve better, more productive output. Proper break-in procedure At the very start of use for any bandsaw blade, break in is essential to extending the life of the saw blade. When …
Bandsaw Tune-Up
Correct bandsaw tune-up is important to achieve optimum performance as well as to preserve the condition of the machine and saw blades. Whether a new bandsaw is purchased or the blades on an existing saw need replacing, spending a little time to make sure all of the adjustable parts are correctly aligned is important to the success of any cutting procedure. It will also guarantee a longer, more productive life of both the machine and the blades used. There are three simple adjustments that will help to keep the saw cut true. It is a good idea to check these adjustments each …
Effective Production Cutting
Effective production cutting is successful production cutting. Making sure the bandsaw is in proper working order and that the correct saw blade is installed prior to starting work equates to being efficient, which then equates to being successful. Effective production cutting can be achieved through the use of the correct bandsaw blade. In order to effectively cut a specific material for a specific job, or to properly maintain the bandsaw machine to be used for the job, the right saw blade is imperative. Two factors to consider when choosing the right blade for the material are speed and feed rates. Speed and …
Bandsaw Feed Systems
Bandsaw Feed Systems are the pressures applied to the bandsaw blade by the materials that are being cut. Feed Rate is an important cutting variable that is defined as being the amount of material (in square inches) that the saw is set to cut in one minute, S.I.P.M. (Square Inches Per Minute). The feed system should not be erratic, and the bandsaw movement should be smooth and steady. Different Methods of Feed System Gravity — the bandsaw falls under the head’s weight and has movable weight which allows for adjustment of the feed pressure Gravity/Spring — similar to gravity feed, but with the use …
Speed and Feed Rates
The relationship between Speed and Feed Rates is vital to the proper function of a bandsaw and requires a saw operator’s full attention or the bandsaw will fail to perform as expected. Speed Rate A saw blade’s speed is defined as the distance in feet that the blade travels per minute: a measurement of S.F.P. M. or Surface Foot Per Minute. In order to achieve proper blade speed, the SFPM must be optimum for the application. The drive belts cannot be slipping under the load being machined, and the tachometer needs to be checked often in order to assure that the proper RPM’s are being …
Band Saw Feed Rate and Feed System
Band Saw Feed Rate and Feed System. Feed Rate and Feed Systems in band saw operation are important cutting variables that impact production rate and machine-ability. So, what is Feed Rate and the various types of Feed Systems that exist? The Feed Rate is defined as the amount of material (in square inches) that a band saw can cut per minute. This number or amount is often referred to as S.I.P.M. (Square Inches Per Minute). Critical to the proper operation of a band saw is the smooth steadiness of the head of the saw as it drops onto the material being cut. The feed should always be …
