Alloy-Specific Band Saw Setup Improves Finish Quality at Everising

Saws like band saws and circular saws are the time-honored way to cut raw material into useable forms for further machining in industrial applications. Saw cutting is not a simple process. However, as each alloy has different speed and feed requirements to maximize surface quality and minimize waste.

In the video above, we learn how Taiwanese companies like EVERISING MACHINE CO. are advancing industrial saw technology, with company president Shu-Chai Chiao.


“We collect many country’s standards,” Chiao said, explaining how the company stays aware of the cutting requirements of different alloys.


“Every country, every manufacturer, has one number. This is a lot of data that we must collect in our computer side, which we can then put in our machines to choose materials. For example, if we’re using a United States standard, we can use that to get information and know what standard component is inside. This information includes cutting data, so we can make it easy to cut the material.”


EVERISING builds their own machine tools in-house, and so designs them to minimize vibration, noise and temperature.


To achieve the smoothest of cuts, EVERISING joined together with a saw blade manufacturer and developed their machines to properly lubricate the saw blades while in contact with the material.


“The cutting surface, whether it becomes smooth or rough is also really important,” Chiao continued. “Our band saws are strong enough and have enough reach that it’s easy to get that smooth cut. We joined together with a saw blade manufacturer and we worked on a solution to lubricate the blades during the cut. We need this for an improved cutting surface. The saw blade, the teeth angle and the way the teeth cut are really important for us.”

Table Saw vs. Circular Saw – Which One Do You Buy First?

So you’ve got a looming project ahead that you’ve decided to tackle, and you’re even willing to drop a little cash on some brand new tools to help you get the job done right.


But where to begin? The marketing world will have you believe that you need this, that, the other, and everything in between to even think about getting a job done. Naturally, you start questioning yourself and your tools: ‘Well, I’ve got a decent circular saw … do I need a table saw for that front deck project?’


This is totally understandable.


Yes, there are certainly specific uses for each and every tool out there. And yes, it’s justifiable to want the tools that’ll help you get the job done as easily, efficiently, and professionally as possible.


Hopefully, this is where we can be of assistance; helping you determines what you need, and what you don’t.


In this article, we’ll rekindle the old, never-ending argument of circular saw vs. table saw: Which one is better? When do you use one or the other? Are there things one can do that the other can’t?


Tune in, and find out for yourself.


Overview: A Tale of Two Saws – Circular Saw vs. Table Saw

To be straightforward, there is nothing a table saw can do that a good circular saw cannot do.


Now, this probably makes the dilemma seem very simple, right? With the choice being to obviously go with a circular saw?


Mmm, not exactly. What that first statement should read is this: ‘There’s nothing a table saw can do, that a good circular saw cannot do at the hands of someone who knows how to use it.”


Contrary to what multiple ‘expert’ DIY’ers (and probably even some professionals) will say, a circular saw can in fact rip lumber, make cross-cuts, precision miters, tenon/dado/lap joints, inset boards, etc.


The key difference is that to the novice user, these precision cuts will be a fair bit easier to make with a table saw, than with a circular saw.


Note that we emphasized the term novice user. In order for a circular saw to be used to its full potential and make accurate rips, miters, etc., you’ll need to use a couple extra tools with it like a speed square, shooting board, or edge guide (we’ll talk a bit more about these shortly). This is where things may get a bit overwhelming for novices.


With a table saw, you can rely more on the tool to make these precision cuts, rather than on yourself. There’s a little less room for error, so to speak. Simply set the miter or rip fence (depending on whether you’re making rip cuts or cross-cuts), and there’s no doubt you’ll get a perfect cut.


The Circular Saw: Range of Use

Like we said, there’s really nothing a circular saw can’t do in the realm of general woodworking.


However, you’ve got to know your way around the tool in order to get the most out of it.


Even for standard 90-degree cross-cuts on narrow pieces of material like 2×4’s, we recommend using a speed square to ensure a perfect, precision cut. Measure the length that you want your cut at, mark it off with the square, then position your blade and use the square as a guide against the circular saw’s fence. If done correctly, this will produce a perfect, 90-degree square cut every time.


The speed square can also be used as a protractor to mark off angled cuts. Simply use the corner of the square as a pivot point, then use the angled side of the square to measure off the exact degree you need. Then you can use the square again as a fence guide to run a perfectly straight cut down the angled line.


For ripping boards, unless you’ve got some otherworldly ability that allows you to run a circular saw by eye on a laser-straight line, you’ll want to use a shooting board, or ‘rip-fence jig’.


The shooting board is a homemade jig that’s built to the exact dimensions of whatever circular saw you’re using. It acts as a fence guide that allows you to make perfectly straight rips, at whatever length you need. If you make the jig right (it’s super easy), you’ll be able to rip long pieces of lumber or plywood with all the ease and accuracy of a table saw. (Instead of going into a lengthy segment on what exactly a shooting board/rip-fence jig is, here’s a great video on how to make one for your circular saw).


Joinery, knotching, and insetting boards is done by simply adjusting the depth of cut on the circular saw blade.


For example, to create an inset on a section of 2×4, simply mark off the desired section to the appropriate length, adjust your blade to the appropriate depth (no more than ½ the thickness of the board you’re insetting), and use the speed square to make parallel cuts about 1/16” apart over the entire length of the section. Then, use a hammer and chisel to knock out the material and create the inset.


Lastly, most all decent circular saws have an adjustable plane, allowing for angled cuts up to 45-degrees – just like an expensive compound miter saw.


The Table Saw: Range of Use

The table saw is an extremely efficient tool because it makes cross-cutting and ripping boards a breeze.


Like we just mentioned, a circular saw can certainly be used to rip or cross-cut, but it takes a special jig and generally a keen hand to really make a great, precision cut.


On the other hand, you’d have to kind of go out of your way to screw up a cut with a table saw, as long as the fence is positioned and set correctly. (Here’s an excellent video on the ease and advantages of a good table saw, and how to properly use one).


Of course, one of the big downfalls of a table saw is its size and non-portability. Unlike a circular saw which you can use just about anywhere, you’ve got to have a bit of a workspace in order to operate a table saw.


Price is also a factor worth mentioning: for overall quality, a circular saw will always be less expensive than its table saw counterpart.


What we like about both, and top picks for each kind


It’s actually pretty tough for us go so far as to say the circular saw is ‘better’ than the table saw. Or vice-versa, for that matter.


Like we explained, both saws are fantastic tools that, under the right hands, will produce excellent results.

Overview of Sawing Machines: Hack Saw, Band Saw, and Circular Saw

Sawing machines are primarily used to part material such as rough-cutting excess material away before machining or cutting curved patterns in sheetmetal. Sawing machines substitute mechanical or hydraulic powered motion for arm motion to achieve the speed necessary for production operations. The cutoff operation is usually one of the first requirements in any production process before any machining, welding, or forging is done. The saw blade has individual teeth that “track” through the workpiece, each tooth deepening the cut made by the preceding tooth in the direction of feed. The saw or work may be fed and by controlling the direction of feed, either straight or curved cuts can be made. The width of the cut (also known as “kerf”) is approximately equal to the thickness of the saw blade and because of this saw blades are made as thin as possible but with adequate tool strength and rigidity.


There are three common types of sawing machines, reciprocating or hack saw, band saw, and circular saw. These machines all perform the same operation but vary in capability, capacity, and application. Power hacksaws use a reciprocating stroke where on the cutting stroke the saw blade teeth are forced into the metal either by gravity or hydraulic pressure while on the return stroke the pressure is automatically removed to prolong saw blade life. Most of the machines come equipped with a chip tray and a cabinet base which contains the coolant reservoir and its circulating pump. Heavy duty power hacksaws come with automatic bar feeds where the stock is loaded on a carriage which automatically moves forward the necessary distance when the cutting is finished. Hydraulic pressure automatically operates the vise jaws, gauges the material, and raises and lowers the saw blade.


After being set up for cutting material to a specified length, the power hacksaw will operate automatically without need for an operator until all the material loaded on the carriage has been cut. Horizontal band saws are one of the most widely used sawing machines for cutoff operations. These band saws range from small manually operated machines to large, fully automatic production machines. Vertical band saws are also used but are primarily manually controlled machines used in tool rooms and shops for maintenance and low production work.


Band saws have several advantages over other kinds of cutoff machines. The saw blade cutting width or kerf is 1/16 in (0.16 cm) compared to 1/8 in (0.33 cm) for power hacksaws and abrasive disc circular saws, and 1/4 in (0.64 cm) for cold saws. This can represent a sizable savings especially when cutting large or expensive material. The thinner saw blades also require less power to cut through material making them more economical to operate. Because bandsaws have endless blades (band saw blades are welded together to create an endless loop) which cut continuously, the cutting rates are much higher.


Two of the most popular circular saws are the cold saw and the abrasive disc cutoff saw. Cold saws are low rpm circular saws for metal cutting. These saws range in size from hand-operated bench-top models with 8 in (20 cm) blades to fully automatic machines with blades of 3 in (7.6 cm) diameter and larger. Light duty manual or automatic machines are sometimes equipped with a swivel head which enables cuts to be made at different angles. These saws are mostly used for cutting structural shapes such as I-beams, angles, and channel sections because the circular blades can complete their cuts with less travel than straight blades. Heavy duty machines are available with bar feeds and can be used for cutting solid bars up to 10 in (25 cm). Material larger than this size would require excessively large blade diameters, which must be more than double the cutting capacity, which would become too costly along with the machine necessary to drive them. Different speed ranges are provided for cutting metals of different hardness and toughness, and built-in coolant systems help produce better finishes and prolong blade life.


Abrasive cutoff saws utilize an abrasive disc to separate material by using a grinding action. Abrasive cutoff saws are built for either manual operation or with power feeds, with either fixed or oscillating wheel heads. Oscillating wheel heads are used when cutting thick sections of tough materials such as titanium, nickel-based super-alloys, and other high alloy steels. Sizes range from small bench-top machines with 8 in (20 cm) wheels to bigger machines with 20 in (50 cm) or larger wheels. Abrasive cutoff saws are very useful for rapidly cutting small sizes of bar stock, tubing, and structural shapes and also for cutting tough or hardened materials that cannot be cut efficiently with other types of saws.
