Redex Group can help design engineers achieve a step-change in the productivity of multi-task machines with its cooling-optimized high-precision drive solutions. Such an advance subsequently presents the potential to capture a larger share of this highly competitive global market.
Not so long ago, the milling tables were limited to the production of prismatic parts with drilling and/or tapping operations, the round shapes of which were produced by low-speed milling. Today, a multitasking machining center can produce cylindrical parts obtained by rapid turning with milling/drilling features on the same machine. – in a single set-up – driving immediate gains in productivity.
But this increase in productivity generates thermal constraints, because with more torque and higher speeds, the power involved exceeds the limits acceptable for conventional drives. The result is temperature problems that lead to machine inaccuracy.
Developing a stand-out multi-tasking machine tool instead requires adapting the drive type and machine structure to achieve the necessary gains in performance, versatility, and precision. However, it demands technological changes.
Motor manufacturers are already offering, air-cooled or water-cooled versions of motors are already available, allowing high continuous speeds while maintaining an acceptable operating temperature. Along the same lines, Redex has for several years been developing cooling options for its drives to ensure effective heat dissipation and the maintenance of operating temperatures compatible with the precision that end users expect from a multi-tasking machine.
