Industrial environmental protection through energy efficiency

February 2012

In industrial applications, environmental protection often has to give way to commercial interests although both interests may be connected by means of targeted improvements in the fields of energy efficiency. This definitely makes sense not just for technical reasons but also since the number of norms and standards is rocketing upwards.

LTA Air Filter type AC 3001 with EC blower

LTA pursues two strategies pertaining to the suction of machine tools in close cooperation with the machine and plant manufacturers.

High efficiency electrostatic filters For the separation of aerosols, electrostatic filter systems are favored for the reasons below. Not only are such systems characterized by a very high efficiency (up to 99% in new condition), but they also function with filter elements which are completely regenerative and almost free of pressure-loss. This allows for reducing the output of the conveyor blowers to a minimum while the disposal costs are limited to the drain water when cleaning the filters. The fact that just minimum cooling lubricant is lost during the transition into the gaseous state when using electrostatic separation is another positive effect.

Custom-made filters Applications where the electrostatic filter can only be used in a limited way, are equipped with "custom-tailored" mechanical filter systems. In such cases, the flow conditions must be optimized in order to realize 100% suction with low volume flow rates. Such optimizations then make it possible to grant the capture of the aerosols with minimum energy input while simultaneously extending the life of the filter elements to a maximum. As expansion stages, the filter systems by LTA may also be equipped with EC blowers which are distinguished by their very high efficiency.

Optimised ROI The company presents a sample calculation for 2-shift operation and approx. 4,000 operating hours per year. At this point, savings reach 39% and the amortization after 1.3 years or 5,400 operating hours.

Laser deposition welding & milling in a single solution

September 2014

The AMB Stuttgart started yesterday with the halls full of visitors. At the DMG MORI booth (quite crowded too), many novelties. Among them, the new Lasertec 65D hybrid machine. Let’s have a look at it. For the first time additive manufacturing is integrated into a high-tech 5-axis milling machine. This innovative hybrid-solution combines the flexibility of the laser metal deposition process with the precision of the cutting process and therewith allows additive manufacturing in milling (…)

Higher productivity with metal bonds - but how do you dress them?

September 2014

The integrated electro-discharge dressing technology WireDress® opens up brand new possibilities for grinding with metal-bonded grinding wheels and drastically cuts auxiliary times. According to Fritz Studer AG, it has been possible to increase grinding power in the grinding process by 30% and reduce grinding wheel wear by 70% in comparison with ceramic and resin bonds. Grinding wheels with very intricate con-tours can also be dressed. . Metal-bonded grinding wheels offer particular (…)

Two spindles in a compact footprint

September 2014

At the base of the specifications of the new s100 product line just unveiled by Bumotec, a simple idea: to create a product with maximum productivity in a minimal floor space. This while ensuring both quality of work and accuracy superior to the constraints of the watchmaking world. After 4 years of development, the s100mono and s100multi machines are being marketed and results exceed expectations. Meeting with Charles Dénervaud, responsible for marketing of the near-Fribourg based company. (…)

New internal cylindrical grinding machine for short and long workpieces.

September 2014

The new S141 from Studer has been redesigned from the ground up. However, the development also incorporates the know-how from many decades of grinding experience and consolidated state-of-the-art engineering knowledge. In addition to long-lasting and reliable quality and precision, the use of both cutting-edge and proven technologies, optimal ergonomics and ease of use were also important goals. The machine’s ergonomic design and user friendliness are evident at first glance. Two generous (…)

Bumotec’s new premises for the future

September 2014

The new building the company has started to build is large, clear, widely open and will have very low energy consumption. The work started with a brief ceremony with the presence of the authorities as well as the press on August 29, 2014. Located in Vuadens in the Fribourg Canton, the new building is ideally positioned close to the motorway and for employees; it’s only a few kilometers from the actual site that is definitely cramped and too small. With the planned growth of the company, (…)

Swiss GT 26 – a new generation

August 2014

Following six high-profile years on the market the Tornos Gamma 20 is now giving way to the new generation - the Swiss GT 26 (capacity 25.4 mm with end bar preparation); this machine will take Tornos to a new level in terms of performance and functionality. The Swiss GT 26 uses the same kinematics that made the Gamma 20 machine so successful. It allows operators to quickly get to grips with the machine. The GT line is made up of two models equipped with 5 and 6 linear axes. The 5-axis model (…)

Gear cutting at the forefront of technology

August 2014

In microtechnology, gear cutting is an operation adding value and if it is possible to realise the parts by different means, the use of a dedicated machine remains very often the best solution. Meeting with Mr. Sébastien Giran, responsible for marketing at Affolter Technologies SA. “Gear cutting in small diameters is our specialty and we are able to propose the most effective solutions by offering the best quality to our customers” says the Manager to start. In this logic of answering to (…)
