Double helical gears are a special type of gear in which two helical gears are arranged in a mirror image configuration on the same shaft. This design can withstand high loads and is significantly more cost-effective to manufacture than herringbone tooth profiles. Double helical gearing combines the advantages of helical gearing, which can absorb high loads, with the additional benefit of compensating for axial forces through its mirror-image arrangement.
The insertion of field rifling profiles into a barrel – such as those used in sporting rifles – is a very demanding task. The complex internal geometry is difficult to achieve using conventional cutting and forming tools and must be manufactured with extreme precision. While forming processes are often used, they require high capital investment and generate additional process costs. Electrochemical machining (ECM) from EMAG offers an alternative: a fast and effective process that delivers high-precision surfaces. In this interview, Daniel Plattner, Technical Sales Manager at EMAG ECM, discusses the possibilities of this innovative production method for rifling.
Today we talk to Syl Kastrati, responsible for development at EMAG, about the new diagnostic tool EDNA Health Inspect, which has been specially developed for VL (Single/Duo), VSC (Single/Duo) and VT.
The design and development of coated brake discs are becoming increasingly important in the automotive industry. The main driver behind this shift is the need to reduce brake dust emissions, as mandated by international regulations like GTR 24 and the Euro 7 standard. These regulations set strict limits on particulate emissions (PM10): capping them at 7 mg/km for passenger cars and as low as 3 mg/km for electric vehicles. These standards will be enforced across the European Union starting in November 2027, with a similar regulation expected to take effect in China between 2028 and 2030 under the National 7 standard.
To meet these emission targets, manufacturers are increasingly turning to coated brake discs, with Laser Metal Deposition (LMD) emerging as a promising technology. However, the precision required to manufacture these complex components presents significant challenges. The key to achieving high-quality, cost-effective brake discs lies in the coordination between the laser coating process and the subsequent grinding process.
Since its foundation almost 50 years ago, Wandel CNC-Technik GmbH has developed from a classic “garage company” into an established supplier with its own products. Over the years, the second-generation Swabian family business has continued to expand its manufacturing spectrum: from milling to turning and grinding. With the investment in an EMAG WPG 7 angular plunge-cut grinding machine, the grinding capabilities were specifically expanded. In an interview with Gottfried Wandel, we learned detailed insights into the company’s history, the production process and, above all, his experiences with the new grinding machine.
In today’s interview, we talk to Patrick Knab, Team Leader EDNA Operations. He gives us exciting insights into the extended functions of EDNA ONE, which significantly simplify the operation and parameterization of machines. In particular, we look at the benefits of “Feature Correction” and “Production Status” – two key functions that make the production process more efficient, safer and more reliable.
The USC 21 from EMAG is a high-performance special-purpose machine for the precise machining of pipe ends and OCTG components. It reliably and flexibly handles the full range of API, GOST, integral and premium threads – with maximum production accuracy.
In modern manufacturing , there are several processes for producing tooth profiles. Three frequently used – yet often confused – important technologies that are often confused are hobbing, skiving and power skiving. Each method has its own applications, advantages and limitations. Understanding the key differences is crucial in selecting the right technology for each job.
Turning balls, especially in safety-critical areas such as the automotive industry, places the highest demands on precision, repeatability and cycle time. Components such as ball pins in ball joints play a central role in steering and chassis. Their production requires state-of-the-art turning technology – especially when it comes to large quantities and economical processes.
Whether for the development of new oil fields or the reliable extraction of natural gas, pipes and couplings are among the most critical components in the drilling process. They carry immense loads, transmit high torques and must remain permanently sealed.
But what makes a perfect threaded connection? What challenges are involved in manufacturing OCTG components – and why are specially designed machine tools so essential? We explore these questions with Udo Lauer, OCTG specialist at EMAG, who shares his insights into the technical world of pipe and coupling machining.
