Ever more stringent regulations are being imposed on carbon emissions from vehicles. One solution to ensure compliance with these regulations is with variable engine timing using cam pieces. The JUCAM 1S from JUNKER is a specialist in the ultra-precise, efficient grinding of cam pieces. With its leading-edge technology and minimal downtimes, this machine enables economical production.
The nerve center of the Jucam is a double workhead with two clamping fixtures. It can be swiveled 180 degrees to a precisely defined end position. The workpiece currently in the loading position is transported to the grinding position using a fully automated process. At the same time, the second workpiece transitions from the grinding to the discharge position, reducing downtimes to a minimum.
In this way, the JUCAM 1S enables automotive manufacturers and suppliers to achieve extremely economical cam piece grinding. The Junker non-cylindrical grinding machine is also a specialist in the efficient package grinding of single cams.
When grinding cam pieces, the precise angular reference to the inner toothing is essential. For this reason, the JUCAM 1S clamps the cam pieces with an inner clamping mandrel. The high quality standards demanded by the automotive industry are fully met by the "cam piece specialist” with its intelligent control system. This compensates automatically for material deviations or disturbing variables such as fluctuations in temperature, guaranteeing that all components conform to a constant standard.
For maximum repeat accuracy, a long service life and high stock removal performance coupled with a consistently high standard of quality, CBN in a range of specifications is used as an abrasive. Depending on the application, the grinding wheels comprise a carbon base body: It is light, has vibration-damping properties and remains dimensionally stable even at high speeds.
With its JUCAM 1S, JUNKER is offering far more than just a grinding machine. The company’s performance promise includes delivery and installation of the machine as well as a grinding process ready adjusted to the customer's wishes and production requirements. In this way, with the JUCAM 1S JUNKER is combining the non-cylindrical grinding of cams with the cylindrical grinding of bearings.
