How to select water jet apare parts？

In metal cutting, water jet cutting technology is a relatively ideal cutting technology, and the choice of water jet apare parts has become one of the problems that must be faced. In order to ensure the efficiency and quality of water jet cutting, many problems should be considered in the selection of water jet accessories. Accordingly, there are many principles, such as efficiency principle, machining accuracy principle, stability principle, economy principle and so on.

First of all, let's talk about the efficiency principle of choosing water jet apare parts. It is inseparable from other principles, especially the economic principle. The main purpose of requiring efficiency is the economy of the whole processing. In order to meet the efficiency principle of water jet accessories, the first is the efficiency under the premise of acceptable machining accuracy and acceptable stability; Of course, efficiency will not be emphasized under all conditions, it is only one of the conditions.

The improvement of the processing efficiency of a part needs to adapt to the efficiency of other parts, and the improvement of the efficiency of a process needs to adapt to the efficiency of other processes. If you ignore these constraints and blindly pursue efficiency, it will have a negative effect, as will the water jet.

The proportion of water jet accessories in the manufacturing cost of workpiece cutting is usually between 2% and 4%, which is not very high, but the influence of water jet apare parts on processing efficiency is very huge. The analysis shows that under the premise of no change in the performance of water jet components, reducing the purchase price by 30% or extending the service life of water jet components by 50%, the reduction of processing cost is not large, because the cost of water jet components only accounts for a small proportion of the total manufacturing cost.

However, if the processing parameters of the water jet spare parts can be increased by 20%, the manufacturing cost can be significantly reduced, especially the cutting speed of the water jet. Although the cost may be increased, the total cost will still be significantly reduced due to the shortening of the processing cycle.
