JUCENTER 6L: CBN high efficiency grinding machine
The JUCENTER 6L grinder replaces multiple individual machines and allows up to three machining stations to simultaneously perform the grinding process. As such, it has a compelling advantage over a single machine that works inline. Not only is the footprint small and the process safe, the tact time is also two to three times shorter than today's usual machining process. In addition, the integrated automatic loading and unloading device reduces the secondary processing time (loading time). JUCENTER 6L processing example:
Grinding of the crankshaft (top) Grinding of the drive shaft (middle) Grinding of the camshaft (bottom) 1. Grinding of the crankshaft All concentric diameters, such as journals and small ends, using CBN multi-grinding grinding process, The connecting rod journal adopts the oscillating non-circular grinding process 2. The grinding groove of the drive shaft, the plane grinding and the grinding of all the concentric diameters. 3. The grinding of the camshaft uses the multi-wheel technology for the journal grinding. Cutting, and cam pair grinding Professional advantages of the production line: overall grinding of the camshaft
At the beginning of this year, one of China's largest automakers used five sets of JUNKER machines to achieve the overall grinding of the camshaft of the 4-cylinder sedan engine. The CBN grinding wheel set and the plunge grinding process were used for coarse grinding and fine grinding of the journal and small end on two JUPITER 500 centerless cylindrical grinding machines. Grinding pairs of cam geometries using a set of grinding wheels on two JUCAM 6L non-circular grinders, using the CNC bevel-cutting cylindrical grinder EJ 3 1 Grinding the shaft end. For the final production scenario, seven machines will be used, which will result in a tact time of only 20 seconds. This line solution is suitable for efficient mass production of camshafts. The use of a continuous CBN process ensures extremely high dimensional accuracy and surface quality with significantly reduced production cycles.
Grinding of wind turbine gearbox shaft
JUNKER has an excellent grinding machine that meets the requirements for large shaft grinding of wind turbine gearboxes – the CBN cylindrical grinding machine JUMAT (platform 6). This cylindrical grinding machine with a clamping length of 2800 mm allows grinding of various types of shaft diameters, shoulders, grooves, tapers and chamfers. The machine is equipped with an integrated measuring system. The measuring system's probe can travel to the various programmable measuring positions on the Z axis, reducing the reject rate to zero. High quality, process safety and flexibility are outstanding features of this type of machine. Data security guarantee through EJ-Backup
JUNKER not only provides efficient and innovative grinding machines, but also provides you with a reliable and future-proof reliable data security solution. With the new EJ-Backup, data can be automatically saved in real time on the same day, and data can be quickly recalled during, for example, after-sales service. The data is stored in a flash card with 8G storage capacity integrated in the machine control system. This allows you to use Backups directly on your machine. This solution not only increases the utilization of the JUNKER grinding machine to the maximum extent, but also extracts the most recent backup within 24 hours and six backups of real-time data. In addition to the daily backup backup, manual data protection can also be implemented through the call of the JUPRO operator interface. And a lot of data is also stored in that integrated flash card.
