l Waterjet cutting offers a cost effective, efficient and flexible method of cutting most e

materials including metal, glass, stone and plastics using either pure water or c additional abrasive. The process produces cuts with a narrow kerf and smooth u

t

edges with no material degradation over a wide range of thickness' upto 150mm.. t

Machine Details The Techserv water jet machine is equipped with a Techserv C.N.C. and a machine control panel. The Techserv CNC is a ‘state of the art’ PC based motion controller featuring colour graphics, touch screen, Intel processor, intuitive operator interface, local area network connectivity etc. The Techserv CNC is fully optimised for water jet cutting, this combined with a position loop update time of less than one millisecond makes it the ideal choice for the low speed - high precision demands of a water jet cutter. The machine control panel has switches for all machine functions including drives on/off, head select, raise lower, set height etc. All the machines electronics are mounted away from the machine in a stand alone operators console.

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 c

with stainless steel covers, all fasteners are also of stainless steel. u

The main drive motors are located within the legs beneath the water tanks t

t

skirt, this ensures the sensitive drives are protected from both abrasive and i physical damage. This method of construction gives the machine a very n clean appearance with all the mechanical components out of view. g

Machine Details continued

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 P

either side of the tank with the outboard slide being adjustable, this r prevents the machine binding due to expansion of the metal and so cannot o

overload the drive motors. f
