Alloy-Specific Band Saw Setup Improves Finish Quality at Everising

Posted on by

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?

Posted on by

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.

Horizontal Machining Center Vs. Vertical Machining Center: Is a VMC or an HMC Better?

Posted on by

Every year, Modern Machine Shop does studies on the machine shop industry. One of the most helpful things they do is their Top Shops report, which does a detailed breakdown of the differences between what the fastest growing and most profitable machine shops are doing compared to the “average” machine shop.

 

Horizontal Machining Center Costs and Benefits

 

The top shops had higher gross sales per machine that average shop – $266,123 versus $152,000. That is huge. One of the major differences: top shops spent 10% of their gross revenues on equipment versus 2% for average shops.

 

One place that makes a difference: invest in horizontal machining centers. You probably know that a horizontal machining center (HMC) costs more than a vertical machining center (VMC) – but do you know that 61 percent of the “top shops” invest in HMCs – and an additional 41% of them also invest in multi-face tombstones?

 

More important: an HMC can be as productive as two or more VMCs. In fact an article written by Modern Machine Shop in 2013 called “Worth Three Machines” highlighted how one company used its HMC to do as much work as 3 VMCs.

 

Review of HMCs vs VMCs

 

HMCs cost a lot more than VMCs. How much more? The Association For Manufacturing Technology says the average HMC costs $375,000 vs. just $115,000 for the average VMC. That’s why 4 times as many VMCs are bought than HMCs every year.

 

If you look at just the cost of the machine, it might make sense to purchase a VMC, but if instead of looking at the price, you look at what you get for each dollar spent, the numbers look a little different.

 

Since very few companies pay cash for their machines, let’s look at monthly payments on HMCs Versus VMCs:

 

For an easy comparison, we’ll look at a 5-year lease on each machine, assuming your company has a good credit profile.

 

  • HMC average cost: $375,000. Average monthly lease payment: $7,050 per month
  • VMC average cost: $115,000. Average monthly lease payment: $2,250 per month
  • Difference in monthly payment: $4,800 per month

 

OK, so a HMC costs, on average, $4,800 a month more than a VMC. Yes, that’s a lot more, but the real question is:

 

Will the extra profits you reap by having that HMC be more than that $4,800 a month?

 

The key driver in machine tool utilization is spindle run time. This is where HMC’s really shine. The average spindle run time on an HMC is 85% versus 25% on a VMC. So what does that mean? That means, on average, less than a third of the labor required to make the same part.

 

Whether it makes sense to invest in the HMC depends on your business model, as obviously the savings in setup times from the HMC are more important on long runs than on short runs, but if you do any long run stuff at all, the savings are pretty apparent.

 

Figure the minimum cost of a machine operator after accounting for wages, benefits, labor burden, etc. has to be roughly $6,000 a month. Since your HMC can do the work of three VMCs, it would cost $18,000 in labor to do the same work on VMCs as you get done on HMC’s.

 

True Costs and Pricing of HMC VS VMC

 

OK, yes, the example above is a little bit simplified, but doing an apple to apples comparison, it gets us “close enough” to the info we need to make a decision. With everything else being equal:

 

An HMC costs $4,800 more per month to finance than a VMC.

Using a VMC will cost you $12,000 per month more in labor than an HMC.

All other things being equal, the HMC will save you $12,000-$4,800, or $7,200 a month.

 

Let’s repeat that: after taking into account the extra monthly cost of the HMC, it will still save you $7,200 a month in labor costs.

 

As an added bonus, more expensive equipment can typically be financed for longer period of time: on the average $375,000 you would be able to finance for 7 years instead of just 5, which would drop your payment from $7,050 per month to $5,450 per month.

 

In both cases, if you lease you should be able to write off the entire payment as an operating expense, with the option to buy the equipment at the end for 10% of the original price. Another option, is an equipment finance agreement, which costs a little bit more (roughly 8% higher payments) but you would own the equipment at the end for $1.

 

The advantage of leasing over buying – tax treatment. Prior to January 2014 Section 179 of the tax code gave you a huge upfront deduction (up to $500k) when purchasing but that number has been curtailed to just $25,000 for 2014 so leasing is starting to make more sense for most companies.

 

Which Is Better?

 

The choice of Horizontal Machining Center or Vertical Machining Center depends on your business model, and some other things, but hopefully this article has given you something to chew on while making this decision.

Does Automotive Wheel Machining Benefit From a Purpose-Built Wheel Machine?

Posted on by


Victor Taichung Machinery Works, based in Taiwan, makes a wide variety of machine tools, including turning machines and multi-purpose milling machines, but an interesting specialty application of the company are wheel machines.

 

In the video above, we speak with Wayne Hsueh, director of overseas marketing division at Victor Taichung Machinery Works about the difference between wheel machines and general purpose multi-axis machine tools.

 

“The car wheel machine is for clamping the part, because for the part to be clamped, you need a special chuck,” Hsueh explained.

 

“Usually for special purpose machines, the chuck is the key component to reduce setup time and for clamping efficiency. Wheel chips are also different from steel chips, so even a chip conveyor and the protection of ball screws are also somewhat different. For special purpose machines, you should pay attention to the kind of part you’re making, what kinds of chips are produced, what kind of coolant you use and how you dispose of it.”

 

Hsueh explains that Victor Taichung’s special-purpose wheel machines are actually modified general-purpose machines – this saves costs for the company as well as its customers.

 

“We can mass produce all the machine parts, as 80 percent of parts are compatible (between machines),” Hsueh said. “We have some customers that want special-purpose machines only and we pay a lot of attention to them. If we increase production of our general-purpose machine, the special-purpose machine would also become cheaper. We like it cheaper for mass production. That’s why we have a special machine for wheels, but wheel machines are heavy duty for heavy cutting. You need a very reliable machine base and fortunately at Victor Taichung Machines, we build the machines this way from the beginning.”

Press Brakes vs. Folding Machines – Which Is Right for You?

Posted on by

There is a lot happening on the fabrication floor. Often time’s conflicts arise as to which machine to use for certain jobs and this can lead to confusion.

 

While at first glance it may seem like press brake machines and folding machines are the same tool made to tackle the same jobs, the truth is that they both have their niche and should have a place in your factory.

 

Let’s take a look at the two fabrication tools and see just how alike and different they really are:

 

Press Brakes

The first thing that sets a press brake machine apart from a folding machine is the most obvious: force. The punch of a press brake uses a lot of force, which means it is geared for heavier and thicker sheets of metal. It still offers precision and accuracy, but it just does so with much more substantial sheets of metal.

 

This means that press brake machines will produce stronger pieces meant for support. Also, press brakes should probably be used for applications that only require one tooling setup.

 

Folding Machines

While folding machines also bend metal, the difference between it and a press brake is how that bend is achieved. Folding machines use much less force, leading it to be used for much thinner sheets.

 

Where the force of a press brake could potentially scratch and damage a very thin sheet, a folding machine is much more delicate and produces items where look and style are paramount.

 

Folding machines will be much better and quicker with panel work of all sizes. They are also better for jobs require multiple tooling changes.

 

Can They Coexist?

Absolutely. It can be very beneficial to have both on your fabrication floor in more ways than one. While a press brake machine can handle panel work, it is going to require more time to tackle a project that a folding could knock out more accurately and with fewer operators.

 

Folding machines can free up your press brake machine by taking on smaller, more delicate tasks and allow it to be more productive – think of it as a companion instead of a replacement.

Everything You Need To Know About CNC Equipment

Posted on by

CNC machines are electro-mechanical devices that manipulate machine shop tools using computer programming inputs. Did you know? The name “CNC” actually stands for Computer Numerical Control and it represents one of two common methods to generate prototypes from a digital software file.

 

The first CNC equipment was developed in the 1940s and 50s and relied on a common telecommunication data storage technology known as “punched tape” or “perforated paper tape.” Punched tape technology is long obsolete as the data medium quickly transitioned to analog and then digital computer processing in the 1950s and 1960s.

 

How Does CNC Equipment Works:

 

Machining in general is a way to transform a stock piece of material such as a block of plastic and arrive at a finished product (typically a prototype part) by means of a controlled material removal process. Similar to the other prototype development technology, FDM (3D printing), CNC relies on digital instructions from a Computer Aided Manufacturing (CAM) or Computer Aided Design (CAD) file like Solidworks 3D. The CNC machine interprets the design as instructions for cutting prototype parts. The ability to program computer devices to control machine tools rapidly advances shop productivity by automating the highly technical and labor intensive processes. Automated cuts improve both the speed and the accuracy with which prototype parts can be created – especially when the material is critical (such as is the case with polypropylene – read more about polypropylene).

 

Oftentimes machining processes require the use of multiple tools to make the desired cuts (e.g. different sized drill bits). CNC equipment commonly combines tools into common units or cells from which the machine can draw. Basic machines move in one or two axes while advanced machines move laterally in the x, y axis, longitudinally in the z axis, and oftentimes rotationally about one or more axes. Multi axis machines are capable of flipping parts over automatically, allowing you to remove material that was previously “underneath.” This eliminates the need for workers to flip the prototype stock material and allows you to cut all sides without the need for manual intervention. Fully automated cuts are generally more accurate than what is possible with manual inputs. That said, sometimes finishing work like etching is better accomplished by hand as well as simple cuts that would require extensive design work to program the machine for automation.

 

Want to learn about the different types of CNC equipment? Read more below.

 

Types of CNC Equipment:

CNC machines typically fall into one the two general categories: conventional machining technologies and novel machining technology:

 

Conventional Technologies:

 

  • Drills:

Drills work by spinning a drill bit and moving the bit about and into contact with a stationary block of stock material.

 

  • Lathes:

Lathes, very much the inverse of drills, spin the block of material against the drill bit (instead of spinning the drill bit and putting it into contact with the material). Lathes typically make contact with the material by laterally moving a cutting tool until it progressively touches the spinning material.

 

  • Milling Machines:

Milling machines are probably the most common CNC equipment in use today. They involve the use of rotary cutting tools to remove material from the stock unit.

 

Novel Technologies:

 

  • Electrical and/or Chemical Machining:

There are a number of novel technologies that use specialized techniques to cut material. Examples include Electron Beam Machining, Electrochemical machining, Electrical Discharge Machining (EDM), photochemical machining, and Ultrasonic machining. Most of these technologies are highly specialized and are used in special cases for mass-production involving a particular type of material.

 

  • Other Cutting Mediums:

There are a number of other novel technologies that use different mediums to cut material. Examples include laser cutting machines, oxy-fuel cutting machines, plasma cutting machines, and water-jet cutting technology.

 

Materials Used:

Almost any material can be used in a CNC equipment. It really depends on the application. Common materials include metals such as aluminum, brass, copper, steel, and titanium, as well as wood, foam, fiberglass, and plastics such as polypropylene.

 

Application for Rapid Prototyping:

CNC equipment was the first major break-through in the field of rapid-prototyping. Before numerical control (in the case of punched tape technology) and computer numerical control (with analog and digital computing), parts had to be machined by hand. This invariably led to larger margins of error in end prototype products and even more so if/when machines were manually used for larger scale manufacturing.

 

Application for Manufacturing:

Many novel CNC specialty machines are built specifically for niche manufacturing processes. For example, electrochemical machining is used to cut highly durable metal products not otherwise feasible. Conventional CNC equipment is more adept at and typically used for prototype development than manufacturing.
