STEPCRAFT 840 V2

STEPCRAFT 840 CNC SYSTEM

The STEPCRAFT 840 is now the largest STEPCRAFT machine and has all the improvements of the V2 machines.

      Machine Travel S840    600 x 840 x 140 mm
      Overall Machine size S840    960 x 750 x 400 mm
      Machine Weight S840    31kg
      Passage Height (height between top of bed and bottom of Z axis fixture    175 mm
      Feed Rates    3,000 mm/min (50mm/sec)
STEPCRAFT V2 Improvements
      The frame build and rigidity of the machine has been improved. The aluminium uprights are thicker, the ball screw spindles are thicker, there are now 4 brass rollers on each drive system, The X axis bridge has been increased in cross section.
    Each brass roller bearing and shim combination are individually fitted at STEPCRAFT prior to packing into the machine kits. This results in a play free system out of the box with minimal tweaking
     The machine is now powered by 30V DC as opposed to 19V DC. The drive torque/power of a stepper motor is strongly related to the applied drive voltage. As such the speed the machine can run as is greatly improved. The rapid stable feed rate of a well tuned STEPCRAFT 840 machine is 3000mm/min.
     The cable management is now “through” the machine frame and under the machine instead of towards the back of the machine in a plastic pipe
