In metal cutting and fabrication shops around the country we take one if the simplest tools for granted;The Bandsaw. While it’s one of the first machines added to a fabricator’s shop, it also can be one of the best or frustrating assets a shop can have. Selecting the right saw, right from the start, is a critical step to ensure your future success. We have put together this helpful guide to with a little assistance from our friends at Do-All Saws to assist you in making the right choice when choosing your new or used band sawing system.
The 4 Critical questions you need to know when looking for a horizontal bandsaw are:
Will you need to cut Miter or Straight cuts only?
Do you need to Bundle-Cut material
Do you need Automatic, Semi-Auto or Manual Operation
Will you be using the Saw heavily (Extreme) or just a few hours a week (Intermittent Duty)?
Miter Cutting
Miter Cutting is cutting the material at any angle other than a 90°. Certain saws can adapt for these angles in a variety of ways. Some simply swing the pivoting base of the saw while other pivot the vise holding the workpiece. Others Pivot the whole body of the saw around the clamped material. Moving to the required angle can be a simple manual operation or can be a programmable operation in automatic and larger sawing systems.
Bundle Cutting
Typically found on automatic sawing systems bundle cutting can make short work of a large quantity of sawing needs. Material such as bar stock, angles, pipe, tube aetc all arrive in pre-bound bundles from the steel supplier and sawx equipped with this feature can process them all together without the need to seperate and process one piece at a time. Saws equipped for bundle cutting provide overhead hydraulic clamping on both the shuttle vise and the static vise.
Automatic, Semi-Automatic or Manual
Manual - Manual saw operation is the simplest form of a saw whereas starting the clamping the material, starting the saw blade and feeding the blade down all require the operator to initiate. While there may be hydraulic assistance on the machine (i.e. Feeds, Clamping and Blade Return to Raised Position) the saw still requires manual intervention to initiate the process.
Semi-Auto - Semi-Automatic operation handles a large portion of the tasks automatically like clamping the material,
Automatic - Automatic operation is the entire cycle of sawing multiple pieces from start to finish with the only operator
Duty Rating - Extreme or Intermittent Duty Rating
An extreme duty saw is likely to run 6 or more hours per shift. In cases of extreme duty usage a heavy-duty sawing system with a wide band blade and more horsepower is recommended as these systems can provide greater productivity and reliability with the overall demands of production and constant usage.
Other Factors to Consider when Selecting a Saw:
Design Capacity vs. Effective Capacity: A saw is most effective in materials from 1/3 to 2/3 of the rated size capacity. Using a 12″ capacity saw is not ideal for cutting 12″ solids all day.
Exotic Materials vs. Mild Materials: Hard-to-cut materials, like Inconel® and 316 stainless, are best cut with high production, heavy-duty machines and wide blades.
Your Budget vs.The Right Machine: - Purchasing a less expensive machine may fall within your budgetary constraints, but not selecting the right machine may cost you in lost production, higher maintenance and in the end, a more frustrating experience. Make sure you take the time to learn what the right system is for your needs before constraining your purchase to a predetermined budget
