Huco Dynatork Flex M Coupling for Flatbed Laser Cutters and Engravers
A UK manufacturer of industrial grade flatbed laser cutters and engravers required precision
couplings for use on their line of laser systems. The company’s machines are globally renowned
for their accuracy in all levels of industry, from small architect model makers and education
establishments, through large automotive plants.
CadCam’s certified Class 1 machines use sealed CO2 lasers that are water or air cooled.
A fine, accurate depth of cut is achieved by software controlled adjustment of both the cutting
speed and the power output of the laser. Closed-loop servo motors and hardened steel rails
provide precision movements with up to 2G acceleration.
Huco Dynatork Flex M (membrane type) precision couplings were selected to help tolerate and
compensate for any slight misalignment in the machines X-axis half drive shafts. “The Huco
coupling enables the accuracy of the X-axis to be maintained by its action on the drive shaft.”
explains Richard Extall, purchasing manager at CadCam Technology. “This is imperative to
maintain the accuracy of our machines, which is to within 0.025 mm.”
Huco’s Flex M precision couplings feature thin pressed steel membranes – torque is resolved
to simple tensile stresses in opposing segments of the membranes. The couplings have
near-infinite life and a dynamically balanced construction which makes them suitable for
applications requiring high rotational speed and motion integrity. CadCam utilizes the double
stage version of the Huco Flex M coupling – two membranes gives even greater misalignment
capacity.
