Machine tools are used for processing work pieces and tools. Cutting machine tools include lathes, drilling machines, milling machines and grinding machines. For all mentioned machine tools, what is important is speed, precision and remarkably good profitability. The SCHMIDT-KUPPLUNG precision couplings are used in a wide variety of machine tools.
Axial stiffness for precise material conveyance
Especially for the manufacture of mass-produced parts, multi-spindle automatic lathes play a significant role thanks to their high productivity and remarkably good profitability. In material feeding, >>Loewe GK axially stiff couplings are used. Thanks to its high axial stiffness, this coupling ensures precise bar feeding besides offering great compensation of the occurring combined radial and angular displacement without deformation in short installation length.
The machine feed cables are located in an application-oriented internal space of the joint coupling.
Dynamic feed with highest positioning accuracy
High demands are placed on the dynamic behaviour of feed drives in modern CNC lathes. On the one hand, accurate positioning of the feeding movement is essential. This required high positioning accuracy calls for the entire drive unit high stiffness. The >>Servoflex coupling supports this through its very high torsional stiffness and backlash-free work.
On the other hand, in feeding tasks, high dynamics is required to meet high productivity demands. Thanks to their mass inertia, Servoflex couplings offer the perfect solution.
High power density in gear machines
Gear machines are continuously working gear machines for manufacturing straight or slanted external or internal gears. In this case, the so-called dividing wheels are of great importance. They synchronise the cutting wheel and work wheel for the metal cutting process. In CNC gear machines, >>Semiflex line couplings in the backlash-free clamp hub version are in charge of precisely driving this dividing wheel. Due to a continuous infeed movement in the work piece processing, the coupling is required to have high radial displacement capacity.
Monitoring of the work flow in machine tools
In many tool technology processes, sensors and shaft encoders monitor the precise work flow. >>Controlflex shaft encoder couplings hereby guarantee the exact and precise recording and transmission of measurement pulses. Through its unique function element, the compact shaft encoder coupling combines extremely low restoring force and low stress on the encoder bearings with constant angle-synchronous transmission of the rotary movement. The coupling is electrically insulating, easy to assemble and designed for up to 25,000 min-1.
