HMF Invests To Boost Production Capacity

Danish family-owned crane manufacturer HMF has invested heavily in automated production processes to meet increasing international demand.

HMF Pipe Bending Machine

The company has invested in a brand-new production line for knuckle booms, where the optimized flow ensures that knuckle booms are ready-manufactured in one single workflow, before sending them directly into the fully automatic paint facility.

 

In connection with the new production line, HMF is also implementing a brand-new welding robot that uses leading technology with adaptive welding and a fully automatic conveyor system. A new drilling center capable of handling very big items has also been added to the new production line for knuckle booms.

 

“In general, HMF experiences an increasing demand especially for larger cranes. Thereby the need for more jib extensions increases correspondingly as does the need for hydraulic pipes,” said HMF.

 

In response to this demand, the company has ordered a new fully automatic pipe bending machine for hydraulic pipes, which is to ensure the necessary capacity and delivery time. At the same time, the test capacity for large range cranes has been increased by 50%.

 

Concurrently with the increasing order intake, the number of employees has now exceeded 550 and in March HMF started using two newly refurbished office buildings. This made room among others for an extension of the R&D capacity with more than 25%.

 

The manufacturer is introducing a welding robot at the HMF Welding Academy as well, where the purpose is to train young metalworkers as well as upskilling their existing employees. Here HMF has also invested in analysis equipment for securing the quality of the weld seams.

 

“At the same time as we are investing heavily in new processes, facilities and staff, it goes without saying that we also optimize where we can. For example, we have gone through our entire range of sub-suppliers, and among others we have changed from yellow chromate to zinc-nickel treatment on sub-components to further enhance quality, just as we ensure capacity with our sub-suppliers – among others by Northern Europe’s most modern laser cutter,” said CEO Brian Stage.

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.”

3 Must Have Woodworking Machines for Every Workshop

If you are an aspiring woodworker, who wants to take up woodworking professionally you should give ample thoughts to buying essential woodworking machines that you will need to carry out woodworking projects efficiently. Just like any other craft, woodworking begins with mastering the basic skills and knowledge to use the fundamental tools efficiently. Of course, a lot depends on the kind of projects you want to take up. But make sure that you invest in the essential woodworking machinery gradually. This way you will be able to assess if you really need a particular machine or not. As you gain more experience in the field, you will be able to find more specialized tools that allows you to do more things efficiently.

 

In this article we will not discuss about the basic hand tools that you will need to get started in woodworking, rather we will concentrate on choosing the power woodworking tools, which will take your woodworking experience to a whole new level. The first three woodworking machinery, that we would recommend any aspiring woodworker are: a table saw, a portable planer and a plunge router. With these, you will be able to carry out a number of tasks, right from milling, joinery and shaping.

 

These Three Different Pieces Of Woodworking Machinery Are Very Important:

 

  1. The Table Saw:

 

A table saw is at the heart of every woodworking workshop. There are several reasons why it has that coveted place among the woodworking machinery you have in the workshop– it not only allows great precision in ripping a stock in straight lines but is also useful in cutting it at various angles. It does the basic milling of a stock with ease and is well suited for joinery works.

 

When choosing a table saw, there are a number of factors that you need to consider. The first thing you need to understand is that – it is going to be one of the most used machinery in your workshop, so you must always buy a quality one. The work surface of the table saw should be rigid and strong, and should be able to sail through all types of projects. Ideally, you should buy one that has a handle to raise and lower the blade easily, and another handle that will enable you to adjust the angle of the blade. Another essential feature that it must have is the connection for dust collector. It should have powerful motor that will let you cut through hard wood and make deep cuts. The blades of the table saw are incredibly sharp, so they should come with a blade guard and a power switch that is within easy reach while working on it. Many table saw today come with a paddle switch that can be pressed with your knee or foot if you need to shut it down in an emergency.

 

  1. The Surface Planer:

 

A surface planer is another indispensable woodworking machinery to have in a woodworking workshop. It can help you to be incredibly creative in the work you do by smoothing any rough saw stock to your desired thickness. Gone are the days when a stock was hand planed tirelessly to get the designed thickness and smoothness, a surface planer can help you get the same result in a short time. Typically, a planer has a table of the dimension between 10” to 14” on which you can feed your stock. There are a set of blades that rotates, thereby cutting the wood as it is fed through it. You can adjust the depth of the cut b using the crank at one end of the planer.

 

Another important feature that you should consider having in your surface planer is a dust vacuum. This machine generates a lot of dust, so having a dust collection system in place with lengthen its life. This machine is quite noisy when it is at work, so always wear hearing protection when you are using it. If not used with care, it can be dangerous too. So, adhering to the safety precautions is of prime importance.

 

  1. The Router:

 

Every professional woodworking will have a router in his workshop. It is one of those wondrous pieces of woodworking machinery that can carry out a number of tasks for you – not only trimming and decorative edge treatments but also various joints like mortises, rabbets, and dadoes. By having a router in your workshop, you are adding versatility in your woodwork. By making use of patterns, you can create identical parts from wood.

 

A router makes use of various bits to produce a number of shapes. For beginners, a stationary base router is good enough. It will help you make cuts at a depth you make before making a cut. For advanced woodworkers, a plunge router can add a creative touch to the work. The plunge router bites into the wood, makes the cut and then allows you to lift it back. When choosing a router, choose one that is at least 2 HP or it won’t be powerful enough to carry out various tasks for you. You should also choose one that comes with variable speed. Collet size is another feature to consider. It is important if you want to use various bit sizes. It is important to remember that smaller bit can be put into larger collet size but not vice versa. The power should be within the reach of your fingers, and you should not need to take your hands off the router to switch it on or off.

 

Other than these 3 woodworking machinery, there are a few other power tools that you can consider buying. One is a good jigsaw. It is a very useful tool that can help you in varied tasks like cutting curves. When buying one look out for one that comes with blade guides as it will help in keeping the deflection of the blades to a minimum. Apart from that a handheld drill and a quality random orbit sander with a provision for dust collection are great power tools to have in your arsenal. Quality of these tools should always be of prime importance when choosing these tools and one should always remember to adhere to the safety norms while using them.

Benefits of Using An Automatic Coil Winding Machine

A coil winder is an integral part of all electrical devices present in the manufacturing companies. In such companies, every device either transforms the current or voltage from one rating to the other. To produce these components, a coil winding machine winds the magnetic wires in a circular form over an iron core having magnetic properties. A little additional equipment is also necessary to wind these components.

 

Coil winding machines perform many other tasks apart from winding electromagnetic coils on an iron core. A special type of coil winding device called the automatic winding machine comes with many features.

 

The following are the uses of an automatic coil winding machine:

 

  1. In electrical industries, it can be used for the production of transformers,
  2. It is used in electrically driven motors called AC drives,
  3. It is widely used in solenoids and various other electrical devices.
  4. It is used in telecommunication industries that require automatic winding machines to run transformers.

 

Thus, an automatic winding machine will be in demand till we keep using electrical devices like motors, solenoids and transformers. These devices are for industrial use. However, we need coil winding machines for our home appliances too. Mixer- grinders, air conditioners, fans etc. all require this machinery fitted into them.

 

We also understood that to facilitate a manufacturing process any industry would require an automatic winding machine. Moreover, they also require different types of additional equipment to add value to the production unit.

 

Remember that by using a coil winding equipment will significantly decrease your production costs. These machines are available with various manufacturers. If you are thinking of buying little equipment, you can also search online for reputed manufacturers and sellers of automatic winding machines. A little research will help you make a good buying decision. Firstly, you will have to consult the various manufacturers you have shortlisted and ask them for a quote. Then, you must check whether their add-on equipment is compatible with your automatic winding machine. This equipment would basically include an auto feeder, a bobbin holder, a bobbin remover, inductive parameters measuring equipment and many more.

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.

When Is Ultrasonic Polishing Equipment Justified?

Ultrasonic polishing is ideal and justifiable when work on small to very small details is required.

 

Manual polishing is a very tedious process, and in particular very small intricate detail work requires additional effort and patience. Ultrasonic lapping machines, available now for quite some time, have been improved in recent years to effectively replace certain time-consuming and costly small detail hand finishing work.

 

Ultrasonic Unit Features

By comparison to conventional die profilers, as well as air-powered lapping machines that may have a stroke length of up to ¼ inch, the reciprocating action of an ultrasonic unit ranges only from .00004 to .00012 inches. However, the extremely fast reciprocating tool motion of 21,000 and up to 25,000 strokes per second provides the extra productivity and gives the polisher complete fingertip control when finishing even the most intricate ridges, slots and details.

 

Ultrasonic systems usually consist of an electronic power module (110 or 220 volt) with a slender electric cord that powers the lightweight and easy to manipulate small, ultrasonic handpiece. Commonly, an automatic power feed system in the module adjusts the frequency required to accommodate the various individual abrasive tools that are installed for the finishing process. The systems are equipped with numerous clamps that will accommodate tools ranging from small diamond files to conventional type polishing stones and/or ceramic stones and laps.

 

As with all other power tools, great care and attention should be given when working with ultrasonic machines. Because of the ultra-fast motion, tools that are overly aggressive (especially coarse diamond files, etc.) should never be used. Surfaces that must be flawless can easily be scratched and made wavy or damaged.

 

On the other hand, dense/hard, fine grit ceramic or vitrified abrasive polishing stones or laps made of brass and cast iron when used with premium diamond compound, permit the beginner to acquire a better understanding of the fast cutting powers these ultrasonic systems offer. Note: Only the most experienced operator should use diamond files or diamond stones for ultrasonic polishing.

 

Ultrasonic Applications

We need to stay objective and remind ourselves that ultrasonic polishing is not for everyone. Frequently, ultrasonic systems are perceived to take care of all polishing problems. This is not so. Ultrasonic polishing is not a cure-all for every mold and die shop that does in-house polishing. There are many polishing professionals and/or mold shops—doing mostly mid-size to large work—that may not require an ultrasonic system. In many instances, the units are simply not practical for mid-size to large type work and ultrasonic systems are not recommended to be used on larger details and surfaces exceeding a 3/8-inch square.

 

Nevertheless, ultrasonic finishing has its place in a polishing environment and it is not overstated to say that in some instances the cost of one ultrasonic system may be recouped by polishing three to four multiple cavity/core molds. For instance, an experienced individual, when working with an ultrasonic polishing machine on very small details, may reduce finishing time by as much as 40 percent and up to 65 percent.

 

In the past, there have been several good, but very expensive ultrasonic systems on the market. The name of one system may differ from the other, yet they all practically evolved from one source. However, several new models, which have been recently developed and have proved to be highly effective, as well as very affordable for even the smallest mold shop or polishing house, are now available in the marketplace.

 

Ultrasonic Advantages

Ultrasonic units with super-fast, very short strokes, provide virtual unrestricted fingertip control. By comparison, regular reciprocating tools—such as air-driven or electric flexible shaft-operated die profilers—are more restrictive in movement and less flexible to handle.

 

Nevertheless, die profilers and/or various other filing machines are great for medium to large mold details and when used at a comfortable speed range and proper stroke lengths they will provide excellent finishing capabilities.

 

Ultrasonic polishing is ideal and justifiable when work on small to very small details is required. It is safe to say that the smaller, more intricate or precise the finishing work needs to be, and/or the harder the materials are which require finishing, the more likely it is that an ultrasonic unit will improve polishing time. Subsequently, complicated heat-treated molds and dies, carbide dies or inserts and detailed punches with fine edges and very narrow slots machined by EDM are perfect for using ultrasonic polishing systems.

 

It should be mentioned here that there are other advantages that make certain ultrasonic systems a practical purchase. Meaning, various models offer dual operating capabilities where the electronic power module not only has the ability to drive the ultrasonic handpiece, but also regulate the speed and rotational direction for a variety of rotary and/or reciprocating hand tools. Having these secondary functions presents additional cost savings over single function ultrasonic units as they permit a full range of filing/reciprocating capabilities as well as rotational grinding/polishing using mounted points, burs, polishing brushes and felt bobs. Furthermore, since the rotary or reciprocating hand tools are powered with internal DC motors, the thin electrical cord provides more freedom of movement when compared to flexible shaft powered tools.

 

Summary

When selecting a supplier for this type of equipment it is most prudent to purchase from a respectable company that has been around for many years, offers good customer service and has some experience in ultrasonic polishing, which can be passed on to the customer, even via the telephone.

 

I think Best Diamond Industrial Co., Ltd. will be the most excellent choice. Besdia supplies high quality ultrasonic lapping machine and much more tools for you. Learn more information about Besida, welcome to check out the website here: www.besdia.com
