Bar Feeder Features Upgraded Design and Advanced Productivity



The Minimag 20 features Omron controls and Swiss-type synchronization devices. Hydrodynamic quick-change guide channels allow for quiet operation at high RPM while feeding round, square or hex bar stock with a 17 second bar change time.

The FMB Minimag 20 is an automatic bar loading magazine bar feeder designed for feeding round, square and hexagonal bar material into CNC lathes. Quick change polyurethane guide channels are designed to provide quiet operation at high RPM while feeding round, square or hex bar stock. This feeder is compatible with all types of sliding or fixed CNC or cam operated lathes with spindle bores up to 24 mm.

"The robust design of the Minimag and its support stands are resistant to bending, keeping vibration from bent bars to a minimum for smooth operation," said a company spokesperson. "Its design cuts bar change time in half versus a double-pusher style feeder. After remnant retraction, a single pusher positions the new bar. The entire bar change process takes 17 seconds."

The Minimag 20 features an Omron controller with a servo motor drive to the feed mechanism. "Flexible control of bar length and rate of feed guarantee the optimum practical and economic use of the bar feeder," said the spokesperson. "Easy options on the operator control panel guarantee proper interaction between the bar feeder and the CNC lathe, with parameters clearly shown on the text display."

This model is equipped with a headstock synchronization device, allowing rapid backward/forward movements on sliding headstock lathes without forward feed pressure from the bar pusher to prevent bar distortion.

The polyurethane guide channels can be changed in about 10 minutes to accommodate multiple bar stock diameters. "Oil filled guide channels envelope the stock, providing the ideal guiding system for high RPM turning operations," said the spokesperson. "During this process the rotation of the bar creates a hydrodynamic effect, centering the bar stock in the channel and reducing noise and vibration. The guide channel is securely closed with a toggle lever system while machining bars."

A bushing block steady rest device on the Turbo guides the bar stock between the bar feeder and lathe. The blocks provide feeding of round or profiled material.

Bars are placed in the storage magazine at the side of the guide channel. This area features a loading capacity of 7 linear inches. The new bar is automatically positioned in the lathe ready for facing before the first component is produced. Maximum adjustable feeding speed is 600 mm per second and maximum adjustable return speed is 1,000 mm per second.

The bar remnants are withdrawn to the back end of the magazine and a gripper extracts it out of the collet and deposits it into a remnant basket. The gripping device is used to both insert the new bar into the bar stock collet and to extract the remnant. It is not necessary to chamfer the bar if it is cleanly cut. No adjustment for bar size is necessary and it is completely self-centering. Bar pusher collet changes can be performed in less than two minutes with the pin-on collet feature.
