The most important issue is to consider the overall economy of the lifetime costs. When planning the investment, it would be good to estimate the using hours per week and list different kind of types of use. This helps for planning the costs and service / spare part practices. A waterjet cutting system made by Muototerä has a lifetime of 15-25 years, so it is not only the purchase price that counts. It means in other words that the cheapest system may not be the best solution. If there is poor service and support available, or if there are not all the needed spare parts available, it may result high cost regarding the lifetime of the system. Assuming the lifetime is 15 years for abrasive cutting with 37kW pump, the estimated costs are divided as follows:
Operator cost 51 %
Abrasive cost 15 %
Purchase price 14 %
Service / spare parts 12 %
Electricity and water 8 %
Due to the reason that the operator cost is the biggest cost, it is essential to make sure that the operators are trained properly and have appropriate tools for working efficiently. This can be achieved by professional training and easy to use control and software. Muototerä has been developing these key factors for a long time.
Basic training is done by skilled professionals and the helpdesk is always available. The systems and additional equipment are also designed so that unmanned production can be used.
Muototerä designs the systems so that the usability is the main driver. We test the new functions first though in our own subcontracting production before launching them on the market. It gives as possibility to adjust the design so that the user feedback has been counted. Muototerä has wide range of spare parts available for quick deliveries and has strong experience on service for waterjet cutting systems. This is very important issue when aiming to minimize the downtime on cutting machines. The most expensive hours are those, when the system is not available for cutting.
