KMT Abrasive Metering System

FEEDLINE V

Stable and repeatable operating parameters are a fun-damental requirement for high-quality waterjet cutting.This applies in particular to abrasive applications usedto cut brittle materials,where a constant flow of abrasiveis simply a must.

Wa terjet Systems responded to this demand by developing the FEEDLINE Vabrasive metering system. Controlled through a central CNC controller or apotentiometer, the FEEDLINE V supplies the cutting head with the optimized flowof abrasive, saving material and costs.

The FEEDLINE V TechnologyThe FEEDLINE V system supplies the cutting head with aconstant metered quantity of abrasive. Without this controlledsupply, the mixing chamber for abrasive, air and waterwould become clogged up. With the FEEDLINE V , this iseffectively prevented. It feeds a metered flow of abrasive bymeans of compressed air into a 0.8-liter transfer tank. At thebase of the tank, the abrasive collects on the metering andtransfer wheel whose rotational speed determines the feedrate to the cutting head.

New design of abrasive outlet and control unitThe new abrasive outlet consists of a single component,facilitating maintenance as there are no moving parts. Abypass opening in the outlet component significantly reducesthe risk of cutting water entering the plastic hose throughwhich the abrasive is transferred to the cutting head. Thisprevents water entering the FEEDLINE V housing. The meteringwheel of the FEEDLINE V is equipped with a shaft sealpreventing water from entering the control unit. The housinglid of the metering wheel and the control unit are transparent,so that operators can easily detect any problems occurringin the unit.

Lower costs thanks to accurate controlDifferent materials to be cut require different quantities ofabrasive. The thicker the material, the more abrasive is needed.Accurate metering settings help lower operating costsespecially in units used to cut many different materials on adaily basis. The adjustment range of the FEEDLINE V catersfor flow rates of 0 to 1,000 g per minute. Greater quantitiescan be catered for by changing a shim.

Suitable for integrated or stand-alone controlStandard feed rates can be stored in the CNC controller andtransferred to the FEEDLINE V. Alternatively, the FEEDLINE Voperation can be controlled by means of a potentiometer. Eachcutting head is thereby supplied by a separate FEEDLINE V.

Lightweight and compact design for easy installationThe FEEDLINE V module weighs only 6.8 lbs and can thus bemounted directly onto the motion system of the waterjetcutting unit. The abrasive hose connecting the metering unitto the cutting head is therefore kept very short, which is anadvantage, as long hose length result in poor cuts.

AMS III abrasive management systemThe FEEDLINE is an integrated component and thereforedesigned for use in conjunction with the AMS III abrasivemanagement system. It consists of an ABRALINE III abrasivefeed unit supplying up to four FEEDLINE metering moduleswith abrasive. These can be individually controlled to supplythe connected AUTOLINE™ II cutting heads with abrasive.The perfect coordination of these components results inprecision cuts and makes the system particularly reliableand economical.
