NORBAR TORQUE AND ANGLE

Nortronic

If we asked a handful of prescription order viagra without maintenance engineers what exactly they are trying to achieve when they tighten a bolt, it’s likely that we’d receive a wide range of answers.

Strictly speaking, when we tighten bolts we’re trying to stretch the bolt enough so that the elastic tension within it clamps the assembly together. That’s right – it’s one that’s easier done than said!

In a perfect world we would always recommend measuring the tension in the bolt, as opposed to vipps pharmacy viagra online the torque, because the tension is what we really need to know. In the real world, torque is the simplest way of achieving control in threaded fasteners but it is only an indicator of the tension.

Unfortunately there is no cheap, easy, reliable way to directly measure tension in a order viagra now viagra money order bolt but application of known torque gives sufficient control in the majority of situations.

It is widely accepted that the majority of torque we put into a threaded fastener goes into overcoming friction in the assembly as only between 10 and 15 per cent goes into stretching the bolt to create tension.

Interestingly though, a very slight change in friction can disrupt the torque vs load relationship so if you reduce friction by applying a lubricant, it will result in more tension for a given torque compared with the dry condition.  This can be seen very easily using the Torque Tension Calculator on the Norbar website.

It’s very important that maintenance engineers understand this relationship. Torque combined with angle tightening methods can reduce the uncertainty in the tightening process by reducing the reliance on torque control alone.

For every 360 degree rotation of the bolt, generic cialis sweet the nut advances down the thread by a fixed number of millimetres on a given bolt. This is referred to as the thread pitch. If you bed the assembly together using a low torque value, canadian pharmacy cialis generic every degree of rotation after this will be used to stretch the bolt.  This almost eliminates the effect that variations in friction have on the tightening process compared with torque control used on its own.

Something to be aware of in torque and angle tightening is that you cannot change the bolt type to a bolt with a different thread pitch as it would invalidate the angle required.

The method is relevant to every fastener type though, so engineers need to keep re-evaluating in every situation to determine the best torque-angle combination.

An electronic torque and angle wrench measures both applied torque and angular rotation. This one tool eliminates the need for using an angle gauge or protractor together with the torque wrench. Ultimately it is viagra prescription nhs also more accurate, faster and will be able to record your results for the purpose of process monitoring, control and traceability.

TAKING A STEER ON SHIPBUILDING

Hydrofast GeojeIsland 2b Oct13

Recently I was fortunate enough to embark upon a visit to the ship building region of South Korea. The south east region of South Korea, around the cities of Ulsan, Busan and Geoje Island, is home to three of the largest shipyards in the world – Hyundai Heavy Industries (HHI), Samsung Heavy Industries (SHI) and Daewoo Ship and Marine Engineering (DSME).  These yards dominate the towns and landscapes that they occupy, the HHI yard for example covering an area of 1,780 acres.  Amazingly, this dominant position in world shipbuilding has been reached in just 40 years,  HHI’s yard having been commissioned in 1974.

The visit provided us with an invaluable insight into what our customers are experiencing in this market, their needs and how important a role torque tools and solutions play in modern marine engineering.

What became clear is that a shift has taken place in South Korean shipbuilding towards high value, high sophistication vessels.  While they may still be building container ships, they are now focussed on the very largest such as the Maersk Triple E Class.  The “Triple E” refers to the design principles of: economy of scale, energy efficiency and environmentally improved.  These are not only the longest ships in service but also the most energy efficient per TEU (20 foot equivalent unit) container carried.

The even more fascinating areas are those of FPSO ships, LNG carriers and ultra-deepwater drill ships.  FPSO stands for floating production, storage and offloading and these ships are capable of processing hydrocarbons at sea, replacing the traditional on-shore oil refinery.  All of the bolting applications that exist in on-shore facilities are now replicated off shore and this fact is one of the drivers behind the changing needs for tools both within the shipyards and at sea. FPSO ships typically have many miles of pipes and a multitude of flanges – making torque tools an essential manufacturing and maintenance aid.

South Korea’s shipbuilding industry is responsible for highly sophisticated drilling and production ships such as the Deep Water Invictus and Attwood Invictus (ultra-deepwater drill ships, both capable of drilling in 12,000 ft of water to a drill depth of 40,000 ft). To shed light on the cost of such a ship, the Asia edition of the Wall Street Journal noted that on 16th October 2013, DSME won an order from Trans-Ocean to build one drill ship priced at US$528m.  The article also noted that there are 92 drill-ships worldwide, to be joined by a further 76 drill ships by 2017 – nearly double the amount in just three years!

The ship building market has a huge global influence and in recent years the top ten companies across the world have been based in South Korea. The Korean trade ministry claims that 80% of these aforementioned drill-ships are Korean built, which is no surprise as the market has continued to strengthen since the US recession which had prompted a decline in the European ship building market.

As advancements are made in the Korean high value shipping market, marine engineers need to look to torque solution providers to guarantee accurate, safe and innovative fastenings.


Vodka, Swearing and Camel Milk: What you need to know about doing business in Russia and CIS

After five years working as a sales manager in Lithuania and Latvia, I am now facing the challenge of being Business Development Manager at Norbar Torque Tools in Banbury, Oxfordshire, responsible for Russian speaking countries and the Baltic States.

While working in Lithuania and Latvia, I learned a lot about the ways of doing business in both Baltic and Russian cultures. In the last 8 months I have acquired plenty of experience travelling in Russian speaking countries – particularly Russia, Belarus and Kazakhstan. The knowledge I have gained here has been fascinating and sometimes very challenging.

Take for example the business dinner (which in my opinion is one of the most important parts of my work). What do you think the dress code is there? Pretty formal? No. In Russian and Baltic cultures there are no dress codes! People can come to a business dinner just wearing shorts and t-shirt and feel very relaxed about that. However, if it is your first meeting, or a meeting with the board, they would usually wear something a little more formal.

Another exciting thing is the Russian traditionl drink –Vodka. My personal opinion is that in business dealings with Russians vodka can be used as a chemical weapon. At dinner you will be offered lots of it. After dinner you will be offered even more! Obviously sharing a drink is all in good jest but sometimes some people in Russia will try to get you «too relaxed» under the motives of industrial espionage. So you must always keep yourself under control and keep any important secrets, well, secret. It is also worth noting that swearing in Russian business culture has nothing to do with the Vodka – colloquial language is just part of business conversation!

Food is not something that differs too much across Russia and generally there isn’t anything that will surprise western Europeans…until you get to somewhere like Kazakhstan. I remember once a sales partner in Kazakhstan invited us for a dinner to a traditional Kazak pub. When the meal arrived on the table I realized it was horse meat and the soft drink was camel milk. I remember my colleague who visited Kazakhstan with me posted on Facebook “Just had a horse meat” and somebody from the office replied – “be careful, it might contain beef!” It was the joke of the week considering horse-gate was in full swing back at home in the UK at the time.

So doing successful business in Russia and CIS comes down to four things; casual clothes, swearing, vodka and occasional horse meat.

EvoTorque® – Why it’s the torque of the town

 

Norbar’s research revealed that traditional electric torque tools were giving vastly different results depending on the joint type.  The torque delivered to a hard joint could be more than double the torque that the same tool with the same settings would deliver to a soft joint with great potential to leave bolts under or over tightened and potentially dangerous.  In developing our own electronic torque tool we decided that we needed radically different motor technology and control software to eliminate these issues.

Our solution needed to be accurate, efficient, ergonomic and intelligent. It needed to deliver the exact amount of torque required during the tightening or joint verification process of bolts, across a range of joint types and applications – from the commercial vehicle sector to wind energy.

Our extensive technical studies and development trials revealed the ideal formulation of motor technology, software and exterior design features required to deliver a state-of-the-art electronic torque tool to market. A tool capable of revolutionising accuracy for electric torque tools whilst protecting the workforce from the health concerns associated with machine noise and vibration, such as hearing loss and vibration white finger. The EvoTorque® was born.

The EvoTorque® uses the very latest in joint sensing technology, a patent pending motor design and market leading control software to emit exactly the right amount of torque required to tighten a specific joint.  The required torque can be easily programmed with the touch of a few buttons and the EvoTorque® indicates, using a clear display screen, when the correct output has been achieved.

Delivering this revolutionary tool to market was a milestone in Norbar’s history and we wanted to ensure it out-performed its predecessors in every way. This meant rigorous evaluation including drop tests, water and dust resistance ingress and power cable stress tests. Coupled with a third party verified sound power of 72.3 dB (A) and vibration level of 0.304 m/s2 the EvoTorque® is leading the way in accuracy, efficiency and safety – now that’s what we’re torqueing about!

The EvoTorque® is available in five different torque ranges and two different voltages. For more information visit http://www.norbar.com/.

Vibration White Finger: More care needed when choosing tools

Around 300,000 people in the UK suffer from Vibration White Finger (VWF) – an industrial illness caused by the use of vibrating tools and equipment. Traditionally a miners disease, widespread use of modern vibrating apparatus means workers across other sectors are now being diagnosed.

The commercial vehicle industry is one such sector and concerns are being raised about how much is being done to fully protect staff in this area from the effects of VWF.

Commercial vehicle garage workers are often expected to use an impact gun on a regular basis, but we’d suggest the use of a torque wrench instead which is not only more accurate but also protects the operator from the effects of this unpleasant condition.

If impact has to be used we would say use it sparingly and only to tighten bolts to a specific point well below the required final torque. Using a properly calibrated torque wrench beyond this point will finish the job without the dangerous vibrations.

Intelligent purchasing

Purchasers are often left in the dark on the exact vibration levels produced by tools – knowledge which could help them make better purchasing decisions for the health of their workforce. It can also be said that buying cheaper tools may be cost effective at the time, but with VWF causing some of the biggest compensation claims in British legal history, totalling a massive £1.4 billion to date, it may not be the most savvy financial decision in the long run.

Torque wrenches, such as Norbar’s Pneutorque pneumatic torque wrench, offer dramatically lower levels of vibration than impact wrenches, safe guarding employee health and offering financial security from costly personal injury claims.

VWF, also known as hand-arm vibration syndrome or dead finger can affect the arms, hands, wrists and fingers. Symptoms range from numbness to sever loss of grip or strength and can render suffers incapable of routine activities such as driving or doing up buttons.

Neill Brodey on the Comité Européen de l’Outillage

Mount Etna

The Comité Européen de l’Outillage was held this year in Taormina, Sicily, Italy on the 26th – 28th September.

 

I am writing this on my way home from the annual meeting of the European hand tool manufacturers, known as CEO or Comité Européen de l’Outillage.

Sicily has proved to be a useful metaphor for today’s European business environment as the ever present uncertainty of Mount Etna [pictured] – which had a mini eruption earlier in the week – feels a little like the Italian government, which had a meltdown while we were meeting.

It has been the first in my tenure as President of the CEO and I realised last week how nervous I felt beforehand. When you have dozens of successful international business owners and leaders, there is a pressure to deliver some value. Of course the location in Sicily was warm and vibrant this year and sunshine does create a positive attitude, but for some of our Swedish members, it was nearly a day’s travel door to door.

Our strategy to deliver value is in three parts.  One, to act as the voice of hand tools in the European legislative machine. Two, to find speakers who can stimulate our thinking on future strategies. Three, to allow conversations between like-minded people without contravening anti-trust laws. I think that this year our meeting has succeeded on all three.

We have been discussing the proposed new “Consumer Products Safety Regulation”. This is intended to give all European consumers the same rights against manufacturers or importers. It will replace several national laws and is a complex piece of legislation. Our conversation revolved around the need to declare Country of Origin for safety reasons and, if that was needed, how do you then define country of origin. The legislation as drafted is different to existing international agreements and would result in some tools having two countries of origin! Fortunately perhaps, we agreed that the issue was not this definition, but the simple fact that marking the country of origin on the tool does not provide a safer product or provide traceability of the supplier in case of a complaint. We will therefore make representation both through CEO and through our national bodies on this point.

We had three excellent speakers linked through the theme of innovation. We heard about distribution models, ways of being more creative and where in the global market we might expect changes that offer opportunity. I had several conversations afterwards that showed there is work for us to do as European hand tool manufacturers.

Finally the level of conversation was great, perhaps because the first two points were so strong, but anyway the energy level was fantastic and getting people back into meetings after coffee was harder than normal because of the intensity of the chats.

I am proud that we are part of the European hand tool manufacturing industry and even prouder to lead it this year.

Next year we go to Amsterdam, a little bit closer for the Swedes!

The Norbar Apprentice

It’s been another few months since my last blog and again, plenty has changed on my apprentice journey at Norbar Torque Tools.

My second year is now complete and I’ve been working full-time over the summer on the shop floor. Safe to say, it’s been an eventful few months and I’ve been able to gain further valuable exposure into the day to day running of Norbar Torque in the UK.

In the past six months alone I’ve been placed in Goods In at both Norbar sites in Banbury, with the Stores team where jobs are prepared for processing, and then in the Torque Multipliers Department.

I’ve also recently completed my 10 week HNC manufacturing bridging course so I can take on the full version of the course that begins in September. I’ll be undertaking this one day per week at college over the next two years.

There’s a noticeable jump between second year and third year at college so I was grateful for the support and opportunity to take the bridging course – especially now that I’ve passed! I certainly feel far better placed for the theory intensive full course.

There’s probably still a preconception that apprenticeships are not academic – well this one certainly is! Maths and Science subjects are naturally key to engineering and manufacturing (and the next two years of college for me) and being in my apprenticeship for the last couple of years has really shown me how important these core subjects are to our industry.

Next year will be an exciting one, as I move away from the basics of manufacturing and machining (milling and the like) to some really technical processes. I’ll be sure to update you along the way.

Fake, Counterfeit, and Cloned Products

Sam Ortolani is a torque specialist, based at Norbar Torque Tools Inc. over in the USA. Here he discusses the issues surrounding fake, counterfeit and cloned products in the automotive aftercare market.

We have all heard the stories about fake, counterfeit, and cloned products. Every few months another story makes the national news. Whether it is toothpaste that contains anti-freeze, or baby food that leaves dozens dead, or it is children’s toys that contain lead paint, these stories all emphasize one or two common threads. One, counterfeiting and cloning products is a big and fast growing business, and two, sometimes the results can be tragic.

Fake, counterfeit, and cloned products might be produced with the best of intentions, if we are liberal in applying doubt. More likely though, they are to be predatory – to bite into a market that some company spent years in order to become experts. To be sure, there is never a shortage of people who are lured by saving a few pennies in the spirit of being cost-conscious. This is exactly why the cloning business is growing at the rate it has grown. Often, cloned products are produced with none of the testing, history, quality control, and real-life application experience of the original product. Inferior materials, improper coatings and heat treatment, and sometimes blatant disregard for performance criteria can be the main ingredients of that knock-off. There is a reason why company X’s lug nuts are the best on the market – because company X has 50 years of experience and know-how behind their designs and their processes. Sure, they cost a few pennies more, but you know exactly what you are getting every single time you use one. And more importantly, I like knowing that is what you used on MY car that carries MY kids to school every day.

In the Automotive Industry there are plenty of stories about Knock-off products. We all know stories about headlight assemblies that do not meet industry specifications, and fenders that are nowhere near the original manufacturer specs. Sometimes the results are innocuous – like premature rust, or poor cosmetic fit. But all too often the results can be deadly. Certainly we all know the reason why the “Fastener Quality Act” was instituted – to protect the safety of the public. One of the many driving factors behind the Fastener Quality act was an almost epidemic number of wheel-offs caused by poor quality lug nuts, but also bridge bolts and weapons systems were involved.

There are plenty of documented events where the use of cloned or counterfeit parts has resulted in death in the automotive industry. It is not just wheel hardware that is a problem – brakes, inflators, valve stems, and tools are also contributors to the statistics.

Imagine that moment when you need your brakes most, standing on the pedal, and…NOTHING!

Or your under-inflated or over-inflated tires blowing at freeway speed, because of a cheap valve stem or cloned tire inflator, or poor quality tire gage

Or those just-torqued wheel bolts coming loose, because the knock off torque wrench can’t hold consistent readings, and over-torques or under-torques the lug nuts.

The US Automobile Manufacturers Association estimates that counterfeiting is a 3 billion dollar a year business. Brake pads have been found that were made of compressed wood, grass clippings, and even seaweed. In China, over 90 manufacturers of fake Yamaha motorcycles have been identified. The US Army was delivered fake seat belt parts – that broke when they were accidently dropped! We have even had cases where our products were knocked off, and the gears ground to dust after a handful of uses.

The savings you think you are gaining can be quickly lost by one catastrophic event. It does not take much before that reputation you spent years or even decades building, is ruined because you thought saving a couple of dollars was going to be worth it.
