Abrasive Metering System FEEDLINE IV redesigned
Stable and repeatable operating parameters are a fundamental requirement for high-quality waterjet cutting. This applies in particular to abrasive applications used to cut brittle materials, where a constant flow of abrasive is simply a must. KMT Waterjet Systems responded to this demand by developing the FEEDLINE IV abrasive metering system. Controlled through a central CNC controller or a potentiometer, the FEEDLINE IV supplies the cutting head with the optimised flow of abrasive.
The FEEDLINE IV technology helps to save material and costs.
The FEEDLINE IV system supplies the cutting head with a constant metered quantity of abrasive. Without this controlled supply, the mixing chamber for abrasive, air and water would become clogged up. With the FEEDLINE IV, this is effectively prevented. It feeds a metered flow of abrasive by means of compressed air into a 0.8-litre transfer tank. At the base of the tank, the abrasive collects on the metering and transfer wheel whose rotational speed determines the feed rate to the cutting head.
New design of abrasive outlet and control unit
The new abrasive outlet consists of a single component, facilitating maintenance as there are no moving parts. A bypass opening in the outlet component significantly reduces the risk of cutting water entering the plastic hose through which the abrasive is transferred to the cutting head. This prevents water entering the FEEDLINE IV housing. The metering wheel of the FEEDLINE IV is equipped with a shaft seal preventing water from entering the control unit. The housing lid of the metering wheel and the control unit are transparent, so that operators can easily detect any problems occurring in the unit.
Improved features of the FEEDLINE IV:
+ Redesigned abrasive outlet section
+ Watertight control unit housing
+ Flexible adjustment of control parameters to meet customer requirements
+ Reduced module weight
+ Transparent lids over electronics and metering wheel
+ Powder-coated housing
