Endoprotheses are implants that remain permanently in the body and completely or partially replace a damaged joint. The artificial or prosthetic hip joint is one of the best known such implants. A prosthetic hip joint is generally understood to be a replacement for the femoral head and the acetabulum (hip socket). At the femoral head, bone is removed on the thigh side an...

Spectacles, now more commonly referred to as glasses or eyewear, are mainly worn as an optical aid to correct defective vision and misalignment, in which case they are also referred to as corrective glasses. Glasses can also be used to protect the eyes from the effects, injuries or irritation caused by external influences. And in some cases, people wear them as a fashion...

The entire race team have given their all to create the ultimate vehicle. The best components, in-depth specialist knowledge and an outstanding driver, but it is never enough. All that counts is the title. Every team strives to get that little bit extra. But where does this come from? How can the decisive boost in performance be achieved? Surface processing on the in...

While engineers in the automotive industry are always looking for ways to optimise efficiency, smooth running and emission management, the focus in motorsport is on pushing performance to its limits. As an international technology leader in mass finishing, OTEC designs and builds systems that reduce friction between components, benefiting both the premium car segment ...

Skiving cutters are used to produce gear wheels. The desired geometry is achieved by a process known as gear skiving, which combines the two traditional processes of gear hobbing and gear shaping. Skiving offers a high degree of productivity and flexibility, and compensates for the drawbacks of the two traditional processes. It is possible, for example, to produce gears ...

One of the most crucial components of a working engine system is its engine blades, such as turbine or compressor blades. A turbofan engine, for example, has many parts: at the front, the fan draws in the air and directs it into the compressor, which is composed of several blades arranged in a row and decreasing in size towards the end of a narrowing tube. Using a rotati...

Lamy stands for much more than writing instruments of the highest quality, it also defines a globally recognised brand concept. The Lamy plant in Heidelberg has been manufacturing high-quality and unique writing instruments since 1966. Alongside elegant design and outstanding quality, one of the main elements of the company's strategy is production in Germany. OTEC was a...

The customer’s requirements for finishing gear wheels presented a considerable challenge: a completely new machine concept for holding large and heavy workpieces needed to be developed. The result is the biggest and most powerful DF machine that OTEC has so far put on the market. The task was the deburring of gear wheels, whereby two gear wheels had to be held in each...

Leading manufacturers of forming and machining tools from around the world rely on processes and machinery from OTEC to improve tool performance and quality. Other companies that rely on OTEC products include those specialising in tool re-grinding and re-sharpening. In production, the focus has always been on factors such as cost savings, durability, productivity, qualit...

OTEC machines allow the quality of carbide tools to be improved considerably. The special procedure enables the chip grooves of carbide cutters and drill bits, for example, to be polished to a high gloss. Impact of surface finish Generally the chip flow is dependent on surface smoothness. When the chips are able to flow better, there is less tailback on the cutting...

The workpieces are clamped by means of a mandrel or similar device. Loading can be carried out manually, by the use of a handling system or by a robot (especially for series production). Processing is carried out by immersing the workpiece in a flowing stream of grinding or polishing medium. The media stream is generated by means of a rotating drum with a diameter of up ...

Turbine blades come in all shapes, sizes and materials. In some cases, turbine blades need to withstand extreme environmental conditions. In modern gas and aircraft turbine, combustion temperatures are often well over 1,000°C. This means that very strenuous demands are placed on the surfaces and materials used, as well as on the manufacturing and finishing processes. The...
