The requirements for shaft machining have changed significantly in recent years. Increasing variant diversity combined with decreasing batches present manufacturing companies with new challenges. With the VTC 100 GT EMAG is presenting a machine in which the turning, grinding, drilling and milling processes using a combined lifetool. In the following interview, Marina Manger, Technical Sales at the Grinding business unit, explains how this technology integration makes production more efficient and what concrete benefits users can derive from it.
The forces in a transmission are not always transmitted with the help of gears. There are exceptions, such as the CVT transmission, in which a steel belt or a multi-plate chain moves on conical pulleys. We explain exactly how this works here. There is also some interesting information about this invention, which dates back to the 19th century.
The VLC GT series is one of the most successful new product developments for EMAG in recent years. The combination of the proven pick-up automation system, vertical machining operation and the option of using different technologies for hard machining in the spacious machining area, has made some fantastic production solutions possible.
With the VLC 350 GT, the next biggest expansion stage is being launched. We spoke to Marina Manger, assistant team leader of the TPM-1 application team, about the new machine and the ideas its development was based on.
In the past year, for the first time ever, more than 2 million electric vehicles were sold worldwide as reported by the Center of Automotive Management (CAM). With 60% of the worldwide demand, China is the main driver of this development.
The automotive world is constantly changing and improving. The industry strives to create vehicles with better fuel economy, while also increasing safety and reliability.
The introduction of hybrid and electric alternatives are becoming more popular, and in the years to come we will see these options continue to grow. With this change, certain components of today’s gas driven engines will be replaced with new components and technologies.
The VLC 200 GT is loaded at by the integrated pick-up spindle. The process starts with hard pre-turning of the shoulder and the bore hole in quick succession. Only a few micrometers of material are then left to be removed from the automotive gear by the subsequent grinding process, using either aluminum oxide or CBN grinding wheels.
Transmission manufacturing is among the most innovative areas of passenger vehicle production: This central component has to ensure a high level of driving dynamics, while keeping fuel consumption low at the same time. Transmissions are therefore becoming smaller and lighter, and provide a higher number of speeds. The individual gearwheels are a main focus of the developers. Their production in extremely high volumes requires a high level of efficiency—at high precision, high speed, and highly controlled.
