5 axes milling and more

1 06 2012

While some are always concerned about the Euro crisis and the issues that it is supposed to result in the real economy, others continue to work and to operate their plant as they have always done. This is particularly true for Hermle the German manufacturer of machine tools. Important investments, new products and successful in-house exhibition displaying a record of visitors, attest the success of its strategy.

The C22U Dynamic machining center with the PW 150 pallet loading system. At the foreground the equipment position.

Last year, the company was not only able to realise his second best annual gross sales, but also, in December 2011, the all-time monthly record turnover. This allowed the company to strongly invest in the realization of a new logistics center and in the optimization of the assembly dept. Currently the order backlog is well filled. However, no one is immune to branch-specific short-term fluctuations. But Hermle seems to be able to respond properly and with flexibility.

C 22 U machining center now with Automation
The high performance C 22 U dynamic CNC machining center of Hermle, developed in 2010, can now be fully automated through the PW 150 pallet change system. Specially designed for the dimensions of the parts machined in the C 22, it can handle weights of up to 250 kg, including the pallet. The system consists of an NC controlled drive unit and a turning unit with double gripper. Both units are positioned compactly on the left next to the machine and allow completely free access to the working area of the machine. The pallet changer does not have to be dismounted for transportation, it does not require a floor mounting and is adapted quickly and easily to the machine at the customer’s.

Double gripper
The key feature of the pallet changer is the double gripper which can be used to simultaneously move two pallets in or out with 150 kg transport weight each or, for a one-sided application, one pallet with up to 250 kg transport weight. The maximum workpiece cube has a diameter of Ø 400 mm with a maximum workpiece height of 370 mm.
This corresponds approximately to the workpiece dimensions of the C 22 to be machined. The standard design can handle up to 6 pallets, with the additional storage up to 11 pallets. The side setup station (optionally rotatable) offers ideal conditions for setup in parallel to production time.

Intelligent loading
Pallet change procedure: The spindle moves to the park position into the tool magazine. The top and the expansion bellows of the left side wall are opened together and therefore provide access to the drive unit/turning unit with adapted double gripper. Meanwhile the double gripper docks with a pallet and moves it through the side access of the machining centre into the working area. The free side of the double gripper docks with and lifts the finished part pallet on the NC swivelling rotary table. Rotated through 180°, both pallets are replaced and the blank pallet is placed on the table. The drive unit/turning unit conveys the finished part pallet into the storage or into the setup station

Gold replacement material cuts costs of electrical contacts

31 05 2012

A material that can replace gold on electrical contacts has been developed by Swedish company Impact Coatings. Silver MaxPhase™ is a metal alloy that performs like gold in terms of electrical conductivity and resistance to wear and corrosion, but at a fraction of the cost.

This offers significant savings and cost control for connectors and other electrical components. Using Silver MaxPhase is also a substantially better environmental choice than gold plating, as no hazardous chemicals are involved in the process. “We want to challenge the idea that gold plating is the only option for electrical contacts. An average mobile phone, for instance, has five to ten connectors that could be coated with Silver MaxPhase,” says Henrik Ljungcrantz, the company’s CEO.

New coating
The coating is qualified according to the IEC 60512 and IEC 60068 standards for low voltage and low contact force connectors that are normally gold plated, such as battery and I/O connectors for mobile phones. Silver MaxPhase has the potential to be used for a wide range of connectors and other components.
The metal alloy is applied by physical vapor deposition (PVD), a process that takes place in a vacuum chamber where the material is evaporated and condensed to form a thin film on the object. Impact Coatings has developed the material, as well as processes and machinery for applying the alloy in high-volume production.

Turnkey solution
Impact Coatings offers a range of PVD machinery that can easily be integrated into existing production flows, with much smaller footprints than a traditional wet plating plant. With significantly reduced environmental impact compared to plating with gold, Silver MaxPhase production lines can be installed without conflict with environmental legislation. The production is entirely clean and, in contrast to gold plating lines, no special permits are required.
The range of machinery includes systems for high-capacity reel-to-reel coating of metal strips; systems for coating of individual metal parts; and systems for coating of plastic components.

Springmann focuses on watch industry…

29 05 2012

..and high precision operations. At this year’s EPHJ on booth E42 visitors will be able to discover three different technologies dedicated to highly demanding fields like watch industry and others.

There are always new ways to realize parts or operations and this year’s highlight at Spingmann’s booth will be

  • SLS (selective laser sintering) with precious material
  • Industrial polishing for small parts
  • Two side grinding

 

SLS – still little known technology
The principle of building the parts is simple, a thin layer of metal powder is deposited on the working surface (250 mm x 250 mm), and a laser moves in X and in Y to merge metal on selected locations. Once the “cut” at this level of the part is fully sintered, a new layer of material is deposited and the laser moves to selectively sinter metal at required locations. The part is thus constructed layer by layer. Huge advantage, shapes are not limited by conventional technologies of machining by material removal.
A new world of possible parts opens…

1- digital model of the part, 2-deposition of the first layer of powder, 3-fusion of the powder in the cross-section of the part, 4 – platform goes down, 5-deposition of a new layer of powder, 6 – the operation is repeated until the part is completed (fusion, filing, lowering), 7-elimination of the non-melted material, 8-the part is complete.

.
To be discovered on Springmann’s booth at EPHJ from June 5 to 8 in Geneva. Customers of the company and interested people can ask for entrance tickets at neuchatel@springmann.ch or by phone on +41 32 729 11 29.

Lausannetec refocusing on watchmaking

25 05 2012

The Lausannetec trade fair is closing its doors today. And MCH Beaulieu Lausanne is already drawing its initial conclusions from this first edition: as of 2013, the fair will be responding to the wishes expressed by the players on the market and refocusing on suppliers to the watch and jewellery industry.

Following its inauguration on 22 May 2012, the Lausannetec trade fair will be closing its doors this evening, after a “highly promising” first edition, in the words of Béat Kunz, CEO of MCH Beaulieu Lausanne: “A few hours before the fair closes, we reckon that between 2500 and 3000 buyers have attended Lausannetec – a figure slightly below our expectations”.

Focused on the customer’s needs
The management of MCH Beaulieu Lausanne has already taken a strategic decision for Lausannetec: as of 2013, the trade fair will be renouncing its interdisciplinary orientation in order to refocus on suppliers working primarily in the watch and jewellery sector. This decision marks the outcome of the organisers having listened carefully to the market’s requirements.

More targeted exhibitions?
The trade fair will still be open to players from the medical technology and electrotechnical sectors who offer microtechnology or high-precision solutions which are also aimed at the watch and jewellery sector. In addition, the MCH Group is currently analysing the possibility of a new product in each of these fields and will be announcing its intentions in the second half of 2012.

The GP 16 spindle drive – Feed forces of up to 400 N

25 05 2012

Maxon’s spindle drive program will be extended with the new size 16 mm. This is also an easily configurable complete system with integrated axial bearing for high loads. Version with metric M6 spindle or Ø 5 mm ball screw.

In mechanical engineering, it is often necessary to find a solution for converting rotary motion into powerful linear motion. Precision spindles combined with DC motors make it possible to transform rotary motion into axial motion. Gearheads, motors, encoders and controllers from maxon’s standard program are used to drive the spindles. The individual components of the spindle drives are perfectly matched to each other, resulting in high-efficiency drive solutions.

Wide spectrum of use
Important characteristics for the ball screw are high efficiency, high load capacity and no self-locking. Noteworthy features of the metric spindle are the self-locking function and the lower price.
The spindle drive program in the sizes 22 mm and 32 mm has now been extended to include the smaller GP 16 S version with a diameter of 16 mm. For the planetary gearhead, 14 different reduction ratios are available, from 4.4 up to 850:1. Depending on the reduction ratio and the type of spindle, this makes it possible to achieve feed forces between 35 and 370 N and even up to 400 N for short durations.

Precise positioning
DC or brushless EC motors can be used to drive the system; in total, nine different motor types are available. These motors can also be equipped with compatible sensors (encoders), which are essential for precise positioning. EPOS positioning controllers are recommended for controlling the motor-sensor combination. These controllers feature a wide range of functions as well as CANopen or EtherCat. The controller can directly evaluate limit switches and other sensors. The programmable EPOS P version makes it possible to set up independent, standalone systems.
