MBL40-6 in focus


Focus on a robust bar guide

The design of the new INDEX bar loading magazine MBL40-6 is based on a pusher with an internal collet, which clamps the drilled bar stock. The bar can be moved freely forward into the work area of the machine, and finally the remnant at the end of machining is fed to the disposal station. Unlike other standard systems with pushers and external collets, there are no interference contours protruding beyond the bar diameter here, which were responsible for a significantly larger play in the guide channel.

The system selected by INDEX requires only an addition of 1 mm to the bar diameter for the inner diameter of the guide channel. This ensures high stability and low vibration tendency. In addition, flooding the channels with oil and rotating the bar create a hydrodynamic guide of high running smoothness. It allows bar speeds of up to 7000 rpm on the bar loading magazine MBL40-6. The resulting fluid pad between the bar stock and the channel wall—made of a plain bearing material—allows high speeds even with polygon bars.

The bar loading magazine MBL40-6 is suitable for bar diameters from 13 to 40 mm of round stock and for wrench sizes from 12 to 32 mm of polygon bars. 

Guiding principle

Hydrodynamic guide of bars in oil-flooded channels made of sliding bearing material

  • The channels are adapted to the bar diameter with plastic reducers (bearing half-shells). Simple clip fasteners facilitate the setup of the bearing half shells.

  • This results in optimum guidance of the bar stock.

  • The guiding principle is suitable also for polygon bars.
