EMAG: Using grinding centers to increase machining efficiency

Last year, the global automotive industry experienced a significant rise in turnover, with the United States, China, India, and Russia leading the growth. However, this surge in vehicle production has brought about unique challenges for manufacturers, especially component suppliers. They are now required not only to manage higher production volumes but also to maintain strict safety standards and high-quality output. Even small parts, which often have intricate designs, demand precise manufacturing. This level of accuracy extends to the production of specialized equipment used in the industry. To address these demands, EMAG introduced the VLC 100 G inverted grinding center—a system designed specifically for the efficient and accurate machining of small clamping parts. The production of such components is massive; for instance, gears, planetary gears, sprockets, and flange parts for passenger vehicles often require millions of units. With production cycles compressed to just one day, speed and precision are essential. The internal teeth of gears must be ground quickly, and the loading unit of the grinding machine needs to switch out workpieces rapidly. In many cases, minimizing downtime is crucial for maintaining cost efficiency. The VLC 100 G features an automatic loading system that ensures high throughput and reduced cycle times. It uses a picking system to load workpieces, and as the machine processes each part, the next one is automatically placed on the conveyor belt, reducing idle time and boosting productivity. Another key feature is its inverted machining design, which allows grinding chips to fall freely into the bottom and be efficiently removed, ensuring a clean and safe working environment. Integrated quality control is also built into the machine. A measuring probe is positioned between the processing area and the loading/unloading unit, offering optimal protection against contamination while enabling real-time monitoring of product quality throughout the process. The machine also offers two grinding wheels, allowing for different grinding operations—roughing and finishing. The first wheel is used for removing excess material at high feed rates, while the second performs fine grinding. This dual-wheel system significantly reduces machining time, especially for large-volume production. According to Dr. Guido Hegener, general manager of EMAG, "The combination of intelligent tools allows us to achieve faster and more precise results." Additionally, the VLC 100 G is equipped with EMAG NAVIGATOR software, making programming simple and intuitive. This saves setup time and improves operational efficiency. The machine's compact size—just 4.5 square meters—makes it ideal for space-constrained environments, allowing production planners to integrate it seamlessly into existing workflows without requiring additional floor space. With its advanced technology, the VLC 100 G represents a major innovation in the automotive manufacturing sector. It meets the growing demand for efficient, precise, and flexible production solutions, aligning perfectly with the industry’s expansion. As vehicle production continues to rise, machines like the VLC 100 G will play a vital role in supporting sustainable and scalable manufacturing practices.

Pipette

A pipette, also known as a pipette gun, is a device used to quantitatively transfer liquids. When conducting research in analytical testing, a small or trace amount of liquid is generally removed with a pipette. Pipettes can be divided into gas piston pipettes (Air-displacement pipette) and external piston pipettes (Positive-displacement pipette) according to the principle. Gas piston pipettes are mainly used for standard pipetting, and external piston pipettes are mainly used to handle special liquids such as volatile, corrosive and viscous. Many people ignore the correct use of pipettes and some of the details.
