PRODUCT SHOWCASE: Redex Gears Revolutionise the Versatility of Vertical Lathes

Redex announces the release of a new drive solution for rotary tables of multi-axis milling machines. The high-speed versions of its DRP, KRP and KRPX ranges complement the features of its MSR range of drives.     Both of these one-of-a-kind solutions provide added value to machine-tool manufacturers.

They simplify the design of the mechanical transmission systems of both large rotary tables used on vertical lathes (over 2000 m) and smaller tables used on milling machines. They also improve machine accuracy and allow for smaller machine footprints.

The high-speed versions of the DRP, KRP and KRPX drives use the heart of Redex high-performance planetary reducers, and they offer greater accuracy, rigidity, and momentum. They are the standard drives with the highest positioning accuracy.

When meshed with a drive gear, the two reducers on Redex TwinDrive and DualDrive solutions cancel 100% of backlash.

These high-speed reducers have been "hardened" (using in particular Redex know-how in spindle gearboxes) to allow continuous operating cycles and meet the specific requirements of rotary tables. As a result, Redex high-speed TwinDrive and DualDrive units can achieve rotational speeds of up to 28 rpm-1.

The complementarity of both solutions allows manufacturers to design the right rotary-table drives for specific applications and thus their priorities of speed, power, accuracy and rigidity.

This makes it possible to execute additional functions on the C-axis without any additional mechanical devices or the use of position locking. This maximum accuracy is maintained during milling and positioning operations particularly by the electrical or mechanical preload system.

Solutions that use two reducers are more cost effective and easier to manage. The TwinDrive solution uses two 80-kW motors, which are more standard and often less expensive. Maintenance and spare-parts management is simplified.

Lastly, it eliminates the need for machine-tool manufacturers to design and build their own gearboxes with all the necessary components.
