Redex offers two complementary integrated drives for tables used on milling machines and vertical lathes. They are designed to be easy to use and allow designers to choose the right drive for each application based on priorities of speed, power, accuracy and rigidity.
Redex announced a 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.
"They simplify the design of the mechanical transmission systems of both large rotary tables used on vertical lathes (over 2,000 m) and smaller tables used on milling machines. They also improve machine accuracy and allow for smaller machine footprints," said a company spokesperson.
The high-speed versions of the DRP, KRP and KRPX drives use the heart of Redex high-performance planetary reducers.
"When meshed with a drive gear, the two reducers on Redex TwinDrive and DualDrive solutions cancel 100% of backlash. This guarantees the exceptional accuracy and momentum of Redex drives, which have proven their worth on linear rack-and-pinion systems for many years," said the spokesperson.
These high-speed reducers have been hardened to allow continuous operating cycles and meet the specific requirements of rotary tables. As a result, Redex high-speed TwinDrive and DualDrive units are designed to achieve rotational speeds of up to 28 RPM-1.
"Although the Redex MSR range offers higher rotational speeds, the high-speed versions of its DRP, KRP and KRPX drives offer far greater accuracy, rigidity and momentum. They are the standard drives with the highest positioning accuracy (a few arc-minutes)," said the spokesperson.
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.
Redex is a manufacturer of one-of-a-kind integrated drive systems for rotary tables on vertical turning lathes. Other rotary tables are designed to use two different types of drives when a C-axis is required:
- A main drive for turning operations, driven by a large spindle motor
- And a feed-preloaded gearbox to cancel the backlash during C-axis mode and which needed to be clutched and unclutched to the crown in order to shift to milling. In addition, the main drive would have to be shifted to neutral ratio.
Due to the features offered by Redex's high-performance reducers and the association of these reducers in TwinDrive or DualDrive mode, Redex solutions are designed for high positioning accuracy. They also make it possible to execute additional functions on the C-axis without any additional mechanical devices or the use of position locking. This accuracy is maintained during milling and/or positioning operations by the electrical or mechanical preload system, which continuously manages the counter-torque between the pinions.
"Solutions that use two reducers, and thus two motors, are more cost effective and easier to manage in most cases," said the spokesperson. "Compared to heavy-duty rotary tables used in conventional configurations that require a 160 kW motor, the TwinDrive solution uses two 80 kW motors, which are more standard and often less expensive (even accounting for the cost of both units). Maintenance and spare-parts management is also greatly simplified by the use of the smaller, standard motors."
This is designed to simplify rotary-table design because it eliminates the need for machine tool manufacturers to design and build their own gearboxes with all the necessary components.
The high-speed DRP, KRP and KRPX solutions extend the Redex range of drives, particularly for high-speed milling table
