2019-03-29 Prosthetic hips

Prosthetic hips
The artificial or prosthetic hip joint is one of the best known such implants. With the OTEC method, a flawless, highly polished surface is achieved for both the stems and balls of hip prostheses. Go to press info

2019-02-22 CAN SEAMERS - COST-EFFECTIVE FINISHING WITH PERFECT RESULTS

CAN SEAMERS - COST-EFFECTIVE FINISHING WITH PERFECT RESULTS
Can seamers are used to seal cans. The key functional surface of the tool is the forming surface or groove which joins together the edges of the can and the lid by forming a seam. Can seamers are used in large quantities all over the world.In order to ensure that the tools always maintain a consistent quality, the forming surfaces must be regularly repolished.

2019-02-22 THREADING TOOLS - CUSTOMIZED PROCESS FOR DIFFERENT REQUIREMENTS

THREADING TOOLS - CUSTOMIZED PROCESS FOR DIFFERENT REQUIREMENTS
The requirements to the surface finishing of threading tools could be very different depending on the type of tool. Therefore a very flexible process that adapts to every dimension and shape of tools is necessary. In OTEC-stream finishing machines with pulse drive (Pulsfinish) the tools can be deburred, smoothed and rounded reliably, quickly and economically according to the requirements. Go to press info

2019-02-22 CUTTER BODIES - PERFECTLY DEBURRED AND POLISHED

CUTTER BODIES - PERFECTLY DEBURRED AND POLISHED
For surface processing, two main tasks are involved in the production of cutter bodies: Deburring after milling and polishing after hardening and grinding. The reliable removal of burrs is important for optimum fit of the inserts on the cutter body. A burr-free and flat support surface is important for stability during the cutting process and prevents chipping of the insert. Go to press info

2019-02-21 POLISHING CARBIDE TOOLS

POLISHING CARBIDE TOOLS
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. The polish enables higher cutting values and feed rates to be achieved. The OTEC process not only ensures a smooth, polished flute, but also improves the adhesion of coatings. Go to press info

2019-02-21 INNER FORMING DIES FOR NON-CUTTING PRODUCTION

INNER FORMING DIES FOR NON-CUTTING PRODUCTION
Depending on the process, inner forming dies are exposed to very high pressures combined with high sliding speeds. This means that very strenuous demands are placed on the tools and especially on the surfaces! With OTEC stream finishing machines tools can be processed economically and in consistent quality.

2019-02-21 SHOCK ABSORBER DISCS

SHOCK ABSORBER DISCS
Stamped parts are used in a wide variety of applications in the automotive industry and are used, for example, in shock absorbers. The main processing task is deburring and rounding of the edges. The OTEC disc finishing machines of the series CF allow that sensitive stamped parts will be deburred and rounded quickly, absolutely reliably and process capable. Go to press info

2019-02-21 IN POLE-POSITION BY MINIMIZING FRICITON

IN POLE-POSITION BY MINIMIZING FRICITON
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 and motorsport.

2019-02-21 VALVE SPOOLS - SMOOTHING FOR HIGH CONTACT RATIO

VALVE SPOOLS - SMOOTHING FOR HIGH CONTACT RATIO
For the surface quality of the valve spool it is not only important to deburr and smooth, but also perform defined rounding of the edges. By smoothing the roughness peaks high contact ratios are achieved, leading to less friction and less wear. The result is a more reliable sealing surface at the edges which control the volume flows in the valve. Go to press info

2019-02-21 OTEC finish for LAMY fountain pen nibs

OTEC finish for LAMY fountain pen nibs
OTEC was able to develop an individual process to grind and polish the surface areas of Lamy's nibs to achieve a perfect finish. The nibs are processed in OTEC CF disc finishing machines in a multi-stage procedure. It is only through this that they meet the high quality requirements of the Lamy brand. The advantages of the procedure lie mainly in the speed, reliability and process safety. Go to press info

2019-02-21 Punching dies

Punching dies
A punching die’s surface quality is essential for smooth and efficient stamping, which is why the surface processing methods for these tools are constantly being refined. OTEC offers machines and process technology for smoothing and polishing - for superior surface quality and a perfect contoured surface. The interaction between processing by OTEC and the coating can increase the tool’s output 10- Go to press info

2019-02-14 Skiving cutters for gear wheel production

Skiving cutters for gear wheel production
Skiving cutters are used to produce gear wheels. Surface processing focuses on low chipping and a uniform rounding of the tooth heads and edges. Polishing and smoothing the cutting surfaces in the tooth profile allows chips to flow off better during gear wheel production. The smooth surface also significantly improves the coating adhesion of carbide layers to be applied. Go to press info

2019-02-14 Engine blades for the aerospace industry

Engine blades for the aerospace industry
Engine blades are subject to high temperatures and pressures. Manufacturers have therefore implemented strict regulations for the production and processing methods used. OTEC has developed a special process to improve the efficiency and safety of engine blades. Go to press info

2019-02-14 Parts for glasses

Parts for glasses
Glasses are mainly worn as an optical aid to correct defective vision and misalignment, in which case they are also referred to as corrective glasses. The parts for glasses have to be deburred, rounded and highly polished. Due to OTEC's unique zero gap system, small metallic parts for glasses can processed without damaging and get a flawless, highly polished surface. Go to press info

Fashion Jewellery - A Sparkling Brilliance For Accessories
Fashion jewellery such as decorative clasps and decorations on handbags, as well as rivets and belt buckles, are often made from die cast zamak, one of the most common alloys consisting of zinc, aluminium, magnesium and copper, and also often from brass or steel. Delicate, intricate pieces of fashion jewellery demand maximum precision from the manufacturing process. Go to press info
