The ground shaft that has been ground is on the inspection table: the geometric tolerances and the dimensional accuracy of the bearings are within the micrometer range. Since the Quickpoint (Quick Point Grinding) process was first introduced in 1985, the JUNKER company in the Noltel, Germany has gained a large number of applications in the field of cylindrical grinding. CBN or diamond wheels of only a few millimeters wide can be used on the surface of the workpiece by point contact with a peripheral speed of up to 140 m/s. ZF, a gearbox manufacturing specialist in Brandenburg, Germany, used this process to achieve the most demanding grinding of the main and intermediate shafts in one setup. So there is reason to attribute the potential that has been discovered to this “high-profile projectâ€. Of course, being a collaborator of this achievement is also proud. The gearbox factory in Brandenburg has won a reputation in the passenger car sector for 12 years after being merged by ZF. From the beginning of the united action of the ZF family to today, they have achieved exceptionally successful development. “Friedrichshafen is much closer to us than on the map,†said Dr. Andreas Schregor, director of the passenger car department and administrative director of ZF’s Brandenburg plant. (See picture 1). “The group's entrepreneurial purpose that we feel is very obvious and related to the social environment and the responsibility of all employees.†figure 1 Of course, to achieve success, one factor that cannot be ignored is the core skills, which are already in place at the headquarters in Brandenburg. Optimized gearbox for every model and engine Since 1992, the Brandenburg plant has produced the first manual transmission for passenger cars. All required production materials are supplied by the ZF headquarters in Gmünt, Schwaben, Germany. Just three years later, the Brandenburg plant has already started its first independent research and development work. The result is a synchronous 5-speed manual transmission with 390 Nm driveable torque. Every car needs a gearbox that is configured according to its engine characteristics and can be coordinated according to its fuel class – currently, car manufacturers are producing a wide variety of car models, which is a good prospect for ZF. At present, various types of 5-speed and 6-speed manual transmissions, all-wheel drive transmission lanes and so-called SMG gearboxes have been developed. In these sequentially arranged and hydraulically and electronically controlled gearboxes, the shifting process is no longer mechanically performed by the shifting lever, but rather by the sensing mechanism and the transmission mechanism through the panel operation on the steering wheel. Mr. Edgar Meyer, head of the work and investment plan, is an element of core skills (see picture 1). He said: “In addition to the development of gearboxes, the use of innovative machining processes such as roll milling of meshed workpieces, Grinding and honing, grinding of the shaft and wheel of the drive shaft, surface carburizing and mandrel quenching and simultaneous machining, etc., for this purpose, the processing structure and processing depth must be coordinated: "We use composite The way to machine our units. Each of the individual parts, such as wheels, shafts and synchronous parts, is placed in a machining nest and assembled into structural components during pre-assembly. They are then placed on the assembly line. Final assembly." Always looking for the most efficient process The processing volume that continues to grow every year can only be achieved through a large amount of additional investment. To this end, technical feasibility and economics have become the two focus of consideration. People have conducted in-depth analysis of the problems faced by current processing technologies, and have taken the following optimization measures in a targeted manner: â– Set up a gear-tooth manufacturing island that includes milling machines and deburring machines, configured with linked units and multiple machine tools.

â– Computer-aided, static quality monitoring using online measurement functions,
â– New continuous quenching equipment for non-delayed quenching of parts with tough geometry.
â– Combined boring of the gears by means of a hard turning and grinding process in one setup,
â– honing the gear directly after quenching with the honing head,
â– Maximize dry processing with significantly increased cutting parameters.
