  Construction details
  

  The main chassis is fabricated from precision extruded aluminium beam, onto the front of this the linear roller slides are mounted, to the rear is the helical drive rack. The whole beam assembly is then covered to prevent the ingress of abrasive. To the rear of this assembly is a second aluminium beam to support the high pressure cable chain feeds to the heads, this beam is exposed to prevent water damage to the main beam in the event of a water leak.

  The main legs of the machine are fabricated from water jet cut aluminium with stainless steel covers, all fasteners are also of stainless steel.

  The main drive motors are located within the legs beneath the water tanks skirt, this ensures the sensitive drives are protected from both abrasive and physical damage. This method of construction gives the machine a very clean appearance with all the mechanical components out of view.

  The Zaxis head features twin linear bearings with motion via a belt drive. All slides and drive components are fully covered to prevent damage from abrasive. Automatic height sense is available as an optional extra.

  The twin heads are mounted independently on the beam. Each head has its own carriage with the master carriage being fitted with a drive motor and encoder. The carriages can be locked together for twin head cutting using a drive belt and pneumatic clamp and easily adjusted for optimum plate usage.

  Machine drive is via three AC brushless servo motors fitted with precision planetary gearboxes and encoders. The main drives are synchronised by the C.N.C. Controller to keep the machine square, an automatic routine is performed at power on to home and square the machine. Final drive is via hardened and ground helical rack.

  All the machines running surfaces are sealed linear slides, these combine accuracy, long life and low friction. The main drive has a slide mounted on either side of the tank with the outboard slide being adjustable, this prevents the machine binding due to expansion of the metal and so cannot overload the drive motors.

  The work support / beam catcher tank is fabricated from mild steel with sheet steel sides and base.

  The work support is designed to be easily removable to facilitate cleaning.
