ABRASIVE WATERJET PROCESSING DEVICE

PROBLEM TO BE SOLVED: To measure a flow rate of an abrasive material G in real time.SOLUTION: An abrasive waterjet processing device (1) jets a process fluid (Q) mixed with an abrasive material G from a nozzle (21) to perform processing and includes: a process fluid supply device (31) which supplies the process fluid to the nozzle (21); and an abrasive material supply device 4 which supplies the abrasive material G to the nozzle to mix the abrasive material into the process fluid. The abrasive material supply device 4 includes: a storage hopper (41) which stores the abrasive material G; an abrasive material supply pipe 42 which allows communication between the storage hopper (41) with the nozzle (21); and an abrasive material flow rate measurement device 7 which obtains a flow rate of the abrasive material G flowing in the abrasive material supply pipe 42. The abrasive material flow rate measurement device 7 receives a micro wave M that is transmitted toward the abrasive material supply pipe 42 in which the abrasive material G flows to measure the flow rate of the abrasive material G.SELECTED DRAWING: Figure 2 【課題】リアルタイムで研磨材Ｇの流量を測定する。【解決手段】研磨材Ｇが混入された加工用流体（Ｑ）をノズル（２１）から噴射させて加工するアブレシブウォータージェット加工装置（１）であって、ノズル（２１）に加工用流体を供給する加工用流体供給装置（３１）と、ノズルに研磨材Ｇを供給して加工用流体に混入する研磨材供給装置４と、を有し、研磨材供給装置４は、研磨材Ｇを貯留する貯留ホッパ（４１）と、貯留ホッパ（４１）とノズル（２１）を連通する研磨材供給配管４２と、研磨材供給配管４２を流通する研磨材Ｇの流量を求める研磨材流量測定装置７と、を備え、研磨材流量測定装置７は、研磨材Ｇが流通する研磨材供給配管４２に向けて送信したマイクロ波Ｍを受信して研磨材Ｇの流量を計測する。【選択図】図２
