When a high precision turner designs a machine…

…it finely fits his needs! But to become machines manufacturer isn’t that easy… And yet this ‘ideal’ machine exists today, we discovered it at Humard Automation in Delémont (Jura, Switzerland). Meeting with MM. Georges Humard, Director and Fabio Carabotti, Project Manager.

Humard_Eurotec1
If the finishing tools are mounted ‘like in the old days’ on a balance, there is no need to know how to calculate cams. This one is simply driven like two linear NC axes.

Basically, the concept of this new 7 mm capacity sliding head automatic was developed by Elwin, a Sandoz Foundation owned high precision turning company. After several prototypes, Humard Automation had the opportunity to buy this development to finalise and industrialise it. Mr. Humard says: “We have worked closely with Elwin to develop the best possible machine. We’ve been working several years and now we are ready to enter into the market”.

High precision turner need: productivity and precision
Designed for the high-end watchmaking requiring out of ordinary accuracies and surface finishes, the Dec’Humard impresses with its wide machining area, easily accessible from all sides and by its bed of nearly one and a half ton of mineral cast. M. Carabotti says: “The machine has been designed to achieve very high precision in normal machining; tolerances of a few microns are standard”. He adds: “As the machine is extremely rigid, we can work with significant feed rates while maintaining accuracy. For most of the parts we have analyzed and/or set-up, cycle times are significantly shorter than what is usually reachable”.

High precision turner need: to keep what works
All high precision turners know the principle of the balance driven by a cam to operate the tools, a unique support for two cutter holders. On the Dec’Humard, two finishing tools are mounted on a balance; they are complemented by 5 vertical tools located above the guide bush on independent scraped slides. The machine also includes 5 tools on the front platen and many options (counter spindle, gear-hobbing, thread-whirling, centering optical device, stamping device, bucket recovery system and much more).

High precision turner need: to center tools quickly
During set-ups, centering the tools may take some time if not properly equipped. The Dec’Humard includes a centering optic system mounted on the front platen. Its position is guaranteed; centered and in the axis and does not depend on the ‘hand’ of the operator. So everyone can quickly put the tools in the correct position.

Three companies for an exciting result
It is with the combination of the skills of high precision turners (Elwin), experts in machines overhaul (Seuret) and industrial automation specialists (Humard) that the Dec’Humard has emerged. “It combines the best of our three companies, it represents a century of technology and know-how in a single product” states Mr. Humard. The company is confident for the future and is building a fifth hall on its Delémont site to house the new Dec’Humard product line.

With Dec'Humard the company positions itself on a niche in the market of high precision turning. The one of a Swiss made machine without any compromise on quality or materials. The Director is adamant on this subject: “We are in the heart of the Watch Valley and are proud of the Swiss label, apart from the numerical control, our automatic lathe is 100% Swiss-made and we are committed to promote our regional subcontractors”.

MTU’s center of excellence for blisks opened mid April, following a 20-month construction and installation phase. Blisks, which are high-tech components in which the disk and blades form a single part, are increasingly used in modern engine compressors. MTU is among the world’s leading blisk manufacturers.

Most advanced machine pool
The center of excellence boasts one of the worlds’s most advanced machine pools including a growing fleet of Mikron Milling machines from GF AgieCharmilles. The 10,000-square-meter shop floor area is available for production. When it is completely up and running, the shop will have 20 milling machines, seven combined turning and milling machines, and eight coordinate measuring machines, allowing MTU to expand its production capacity from 600 blisks per year to as many as 3,500 blisks per year by 2016.

Automated process work-flow concept
The Germany’s leading engine manufacturer adapted several high-performance Mikron HPM 800U Milling machines to accommodate MTU’s pallet- and clamping-systems. The shop is designed to house up to 24 Mikron Milling machines as part of MTU’s optimized, automated process workflow system. With one of the world’s largest flexible systems for the production of high- and intermediate-pressure blisks, MTU can manufacture many compressor stages for commercial and military engines.
A 96-meter-long main distribution center—connected to a host computer capable of automatically controlling all processes at any time—is the core of the automated process work-flow concept. Every new component will have a routing card, unique order number and an integral radio frequency identification (RFID) chip.

The order number, in combination with data on the availability of fixtures, tools and computer aided programs, will allow the host computer to calculate the workloads of all of the shop’s work stations and allocate components to the available machines through the main distribution system.

To help punch manufacturer reduce overhead costs by 66%

For almost twenty years, Boise, Idaho company, Performance Design has designed and manufactured paper punching machines used by Staples, Kinkos and in-house printing departments of large corporations.  Today, they’ve got a 6’500 sqm facility with 25 employees where they manufacture and sell over 20 different product lines.

Until late 2012, though, they were outsourcing a key component in their equipment…the round, oval, square and rectangular metal pins used to punch the paper.  The pins are between 3 and 8 mm diameter and about 50 mm in length which includes a 3 mm head gripped by the punch machine.  As part of a company-wide “Go Lean” initiative that began in 2007, they decided that they needed to bring the pin manufacturing in-house, starting with their oval shaped pins.

Swiss ST26 into the equation
 “Actually, we were just about ready to pull the trigger on purchasing a different machine right after the IMTS show; but then we met with our local Tornos salesman and he presented the specs on the Tornos Swiss ST 26 “Starter” machine.  The Tornos looked like a great option and we were really surprised by the price that he was quoting.  Comparing it to similar machines in the market, we were expecting it to be another 100K more than what he was saying.  When we saw the features that the Tornos had for the price, we put the brakes on buying anything else.  We had to start looking at that one real seriously.”  

New possibilities at Performance Design
Once they determined that the Tornos could use round material to make rectangular pins, they were hooked.  “We went back to the other manufacturers to see if they could match the Tornos and their only answer would be jumping up to a $200,000-300,000 machine.  They had nothing in the Tornos Swiss ST price range”.

The right product
The Tornos Swiss ST 26 Starter configuration was a linchpin for Performance Design’s Go Lean initiative. The Tornos was a great fit on price and capabilities and helped them transform the way they manufacture a key component in their product line.

We’re going to publish the full story later. In case of interest just send us a mail with Performance Design as title and we will inform you as soon as the article is released.

To extend the life of machine tools and reduce downtime by 10%…

The Renishaw QC20-W ballbar system is widely recognised as a preventative maintenance tool for new and installed machines. Aquasub Engineering (Coimbatore, India), part of the Aqua Group, one of the largest pump manufacturing companies in Asia, is using QC20-W ballbar to reduce maintenance costs, increase capacity and reduce scrappage.

With an increasing emphasis on Total Productive Maintenance (TPM), Aquasub started looking for solutions and on discovering that Renishaw had launched a new wireless QC20-W ballbar system, decided to get a demonstration. The scope and precision of data given on various machine errors with a QC20-W test amazed them. With up to 18 separate geometric, plug and dynamic errors diagnosed, this gives far more reliable diagnosis than their existing practices.

Multiple benefits of QC20-W use
To reduce the necessity of purchasing new machines, Aquasub want to maintain their 200 existing machines, many of which are 25 years old. Mr K Senthil Kumar, General Manager, explains, “We would obviously prefer to maintain our old machines and return them to their original condition rather than buying new machines. This a more cost effective option than investing in new machines. In order to extend the life of the machine we are also carrying out regular ongoing tests with QC20-W ballbar. We are now able to carry out 3 plane testing with a single set-up which has reduced our maintenance inspection time by 20%.”

Regular testing is the key
Mr Kumar continues: “Test data from each machine is stored in the Ballbar 20 software history function. This allows us to schedule machine maintenance, and take remedial action before part quality becomes an issue. If the machines are in good condition then the component quality will have good repeatability. By incorporating QC20-W into our maintenance program we have significantly reduced scrap and faulty product.”

Backbone of the quality system
The general manager concludes: “We used to base our machine performance reliability on an engineer’s word so the potential for human error was high. Now the QC20-W ballbar provides us with overall machine diagnostics (circularity, squareness and backlash) from a single test. All the machine data is stored in Ballbar 20 software and creates a log of information about each machine’s performance that can be reviewed at the time or offline. We are no longer reliant on an engineer’s memory. The Renishaw QC20-W ballbar system is the backbone of our quality system.”

Eurotec’s apéro at a very successful EPHJ…

Last night we organized our traditional apéro. That was the occasion to share a nice moment with passionate people from our world of microtechnology. Thanks a lot the many customers and friends that came.

And the winner amongst our advertisers for 2013 is Sarix; M. Frank Leleu, marketing and sales manager showing the iPad he had just won!
And the winner amongst our advertisers for 2013 is Sarix; M. Frank Leleu, marketing and sales manager showing the iPad he had just won!

The organisers of the show arrived late because at 6:00 (time of the start of our apéro) they had invited all the exhibitors to come and meet with them to exchange friendly on what is going well and what has to be improved for next year’s show. And?

All positive
The three directors waited for about 20 minutes but none went there to take the opportunity to discuss or complain! And that is the feeling on the whole show, the vast majority of the exhibitors I discussed with told me how the show is positive and how successful they are, with many visits and also new customers and direct orders on the booths. Great to hear indeed.
Questioned about the challenges for 2014, Oliver Saenger director told us: “It is a great amount of work to reach such a level of quality and this success is totally shared with our exhibitors that also work hard. For the future we need first to stay at the level we are today (at minimum) and indeed listen to our exhibitors and visitors to still improve what can be”.

A few novelties
In term of machines, some companies were presenting new concepts or machines:

  • Crevoisier with the polishing cell based on virtual reality (read our article here)
  • VFM Machines with the Roku-Roku high precision machining center (read our article here)
  • Many companies like Mikron, Sarix, Tornos, Willemin-Macodel unveiled a little their news for EMO (but not largely) and if I cannot write anything now, I can say that there are some incredibly revolutionary products coming soon… stay tuned.

Thanks again to all our customers with whom we work to make microtechnology shine a little bit more day after day.

Cheers,

Pierre-Yves

New very small machine to drill horns in watch cases & more…

At EPHJ I’ve just discovered new Emissa machines: the Magic 50 and Horolotoplan. These machines complement the product range offered by Emissa in the watch industry.

Emissa_EPHJ_Eurotec1
M. Pierre Boschi, managing director, with the new Horolotoplan. This machine combines high productivity with flexibility.

Magic 50
This new machine has been developed to offer watchmakers a less expensive alternative to 90° drill in the horn of watch cases.  M. Boschi says: “We already offers the Magic drill, but this machine is mainly intended to produce large series, with the new Magic 50, we offer a “table” machine for small series”.

Horolotoplan
This new machining center works like a transfer machine where the watch plates move from one station to the next one. The machine includes 30 working stations and can completely machine watch plates. It can be equipped with a returning station as well as loading/unloading systems.

New smallest tool
This new toolholder has an outside diameter of 2.48 mm and turns at high speed… it has to be seen…
