CVT transmissions are becoming increasingly popular in the American and Asian markets. The technology improves driving comfort as the car shifts gears more smoothly. A critical part of manufacturing these transmissions is the creation of the CVT components like shafts and disks (“pulleys”) that need to be hard machined with extreme precision– all as part of a multi-stage process that uses various turning centers and grinding machines.
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.
Electro-chemical machining (ECM) is a fascinating production method, because the technology involves virtually no workpiece contact: A direct current, or pulse, is used to polarize the workpiece positively, to create an anode, and the tool negatively, for the cathode. An electrolyte solution flows between the two, and metal ions detach from the workpiece. The components are not exposed to any mechanical or thermal stress during the process.
Increasing cost pressure, high demands on part quality and frequent change of batches – the manufacturing of car brake discs is a difficult field. Particularly in the spare parts market, where users must request individual machining solutions that can be retooled for new workpieces without long downtimes.
This animation shows how easy it is to set up whole manufacturing systems, realized with modular machines. The example of sprocket machining demonstrates how versatile these modular machines are. Read more about the modular machines here…
