Pvd coatings - Import export

Metzner provides a number of proven automation solutions for the automatic loading and unloading of coating carriers for CVD and PVD coatings. The abbreviations PVD (Physical Vapour Deposition) and CVD (Chemical Vapour Deposition) stand for different coating processes. When loading the PVD spears, we differentiate between "single-loading" and "back-to-back loading". In addition to part loading, spacers are loaded onto the spears in addition to the parts. In single-loading, a spacer is located behind each individual insert, whereas in back-to-back-loading, two inserts are placed "back to back" and only then is a spacer loaded. To implement "back-to-back-loading", a turning station is integrated into the machinery. This station is used to turn the corresponding insert by 180 degrees, loading it directly onto the respective spear.

With the DHC Premium solid carbide end mills, LMT Tools significantly increased the performance of the low-vibration premium tools: 25 % added machining volume is the result of different helix angles in connection with newly developed, stable front cutting edges and peripheral teeth. Additionally, the new cutting material LCPK30M including an innovative PVD high-performance coating contributes to an improved tool life and a safe chip removal. A special performance feature of the DHC Premium end mill (Different Helix Cutter) by LMT Fette consists in its multifunctionality: it allows the user to rough and finish with the same tool. It can also produce narrow projections and up to 2xd-deep slots in steel and cast materials with exceptional surface quality. Advantages: - Increase of the machining volume by 25 % - Increased process reliability due to stable cutting edges - Multifunctional – roughing and finishing with the same tool
