Don’t Forget Concentricity

February 13, 2012

As parts get more and more complex, you will see part tolerances get tighter than ever. We’ve all seen the (+ -) .0001” size on a turn or bore, but what about concentricity? Quite often, it’s a call out that’s just plain missed. Catching the spec is one thing, meeting it is another.

Here’s some helpful ideas.

First of all, concentricity starts with “round” features. Remember, you cannot check for concentricity between two journals; maybe the spec is .0003” if one of the journals has .0004” run out in itself.

Second, boring the spindle tooling while positioned in the spindle, especially for the 2nd chucking, is a must. If you’re talking .001”, probably not needed, but if the print calls for .0004” concentricity or less, bore the spindle tooling and your success rate goes up.

Third, for the most demanding concentricity specifications, machine all the critical features together. This trick is pretty well understood in this industry but be careful, it’s not a 100% guarantee. There are a lot of factors that affect concentricity, Example: Balance, tool pressure, excessive part clamping pressures, to name a few….…

‘Solid performance’ as Hardinge looks to 2012

January 3, 2012

“A very solid performance” was John McTernan, Hardinge’s Managing Director, European Sales and Marketing’s description of the UK company’s performance during 2011.With the organisation having met its targets for the year and – despite challenging market conditions – approaching 2012 with a deal of optimism he reflects on the successes that have contributed to the performance.

“We, like so many others, approach 2012 against a backdrop of economic uncertainty but the engineering sector is very resilient and despite predictions of gloom in some quarters of the media, we know from the feedback we get from our customers that while challenging, the mood is still fairly optimistic.

“So many factors are beyond our control but in many respects we said something not dissimilar 12 months ago,” he adds.

Landmark …

Looking at the past 12 months Hardinge in the UK has made a number of landmark achievements, the most notable being the introduction of the Biglia range of high end machine tools and the significant re-branding and launch of the ShopHardinge on line store. Both are beginning to significantly impact on the business with a number of confirmed major Biglia sales in the order book and significant levels of interest in the brand. ShopHardinge activity is running at encouraging levels and there are many new third party products now featured.

Not that the year past has been totally without its problems. “Sales activity has been running at very positive levels” adds John, “but the manufacturing side of the business (in common with most international machine tool manufacturers) has been impaired by problems beyond our control. The devastation caused by the Japanese Tsunami filtered down to machine tool manufacturers with a global shortage of many of the high precision components we are all so dependent upon. Things are slowly improving but the ability to fulfill orders in the time scales we would have liked has at times been difficult.”

Looking ahead …

“In 2012 our major focus will be on integrating our factory operations more closely with the sales side and optimising their activities,” John explains. “This will mean our sales and marketing activities will be able to focus on just that – selling and marketing.

“This will necessitate changes in the state of readiness that we ship units out in but will result in improvements that will benefit the customer,” he concludes.

ShopHardinge expands after successful launch

August 25, 2011

Just weeks after its launch in the UK, the inventory of the extensive Hardinge Machine Tools’ ShopHardinge on-line store has been considerably expanded with a range of branded products added.

Launched in early July with 65,000 products in its online inventory, the  e-commerce web site offers purchasers the opportunity to browse, select and purchase a vast range of products ranging from a simple collet to a sophisticated rotary table.

ShopHardinge has been highly successful in the USA over the past 2 years and early signs are that customers in the UK are equally enthusiastic, making use of its many features,” explains Rob Beckett, Hardinge UK’s Workholding Product Manager.

“As well as purchasing, on-line visitors to the site can check on stock levels and access technical data and already the scope of the site has been expanded,” he adds.

Added since the launch have been tool and workshop storage cabinets and trolleys from Bott, coolants from Q8, a choice of barfeeds from Hydrafeed, Iemca, LNS and Samsys and rotary tables from Nikken.

Most recently, Europa Manual Turret Mills have also been added.  Two versions are offered – the 5000VS with an ISO40 taper and the 2000VS with an R8 taper.  Although budget priced – both at under £10,000 – the machines have a range of features that make them invaluable additions to any small or medium size workshop where the can undertake simple milling operations without the need to disrupt the automated machines.

Rob Beckett explains.  “In adding these and other reputable branded products to the ShopHardinge  portfolio we are extending the ‘one stop shop’ ShopHardinge concept and these new names are expected to be the first of a range of additions,” he concludes.

Kit car manufacturer aims to be self sufficient

August 23, 2011

The acquisition of a Hardinge GS 200 multi-axis turning centre by kit car designer and  manufacturer Great British Sports Cars has been a major milestone towards its goal of being self sufficient for the supply of many small turned components.

Based in Boughton near Newark in Nottinghamshire, GBS has been in business for some 4 years and is well known among enthusiasts for its ‘Zero’ kit car.  As with all kits it is based on what is known as a donor vehicle – in the Zero’s case it is currently a Ford Sierra – but the tubular space frame chassis and a great many of the components that make up the final kit are traditionally sourced from a wide cross section of suppliers.

This in itself can create supply problems as company director Keith Bird explains.

“There is nothing worse than shipping an order to a customer with a number of key components missing and therefore potentially causing a delay in assembling the kit.  We recognised this from an early stage – it appears to be a common cause of complaint throughout the kit car industry – so we set about remedying the situation.”

As a consequence GBS has now bought ‘in house’ a very high percentage of its manufacturing and fabricating operations and with the arrival of the Hardinge machine in early Spring 2011, production of turned parts will be increasingly under their control.

“We offer a very flexible service to our customers and this reflects on the way we supply key components.  For example we might previously have had to purchase simple items such as bushes in quite large batch quantities.  Now with our own machine tool on the premises, we have total control of the manufacturing and can produce quite small quantities in a very short time span if necessary.”

The GBS Zero offers exceptional value for money and GBS has recently introduced a new wide bodied version that is proving very popular. Every aspect of the kit is available from the company with all the key components from the donor car (such as brakes) completely re-conditioned to ‘as new’ standards.  If necessary, GBS can part or completely assemble a car to a customer’s specific requirements.

Manufacturing on the GS200 is under the control of Jonathon Hunter who, on his own admission, is learning as he goes along.  That said he had produced the first component from the GS200 within a week of it being commissioned.

The machine tool is equipped with the very latest Siemens 828D machine control which, among its many features, offers simpler set up and very powerful CAD functions.  The machine is fed via a Hydrafeed bar feeder.

“It’s not an understatement to say the Hardinge machine will play a major role in our future progression as a business,” states Keith Bird. There is a significant market for these types of cars in the leisure and sports market and more and more cars are being shipped overseas.  Therefore we have to offer the most professional back up possible and that necessitates investment in top rate production equipment and processes.  We believe we have a winner with Hardinge.”
