On March 13th, ISCAR released the SPINJET MICRO90 NPA with a stunning interactive announcement document. A lot of hard work has gone into this new product announcement.  You will notice that the document is detailed and informative and includes detailed recommended cutting conditions, by material, application, and machine high-pressure coolant pressure.

SPINJET Case Studies – ISCAR Slovakia covers two case studies completed at the same Customer, LOMAN. The first article focused on the case study involving the chamfering of an aluminum plate and this second article focuses on the case study covering the slot milling of stainless steel. Both with the GJET.

Engraving is an ideal application for jet spindles and process time savings of 6-12X can be achieved, which is the equivalent of saving 80-98% saving in machining time!

Operationally, once the roughing processes are completed on large machines, we need to physically move the rough part to machines that are better equipped to complete the finishing processes efficiently and accurately. This implies a string of additional activities and costs, including additional costly high-speed machines, planning, and machine setup. Ideally, we want to complete all the processing efficiently and accurately on the same large machine and in the same setup. This is much more profitable.

As a reference, when looking at cost of processing a part, machining cycle time is usually 40% of the budget, while the cost of tools (including the costs of Jet Spindles) is usually around 3% of the budget. So, with this in mind, we are primarily concerned with improving cycle times and this article looks at the BIG impact of Material Removal Rates with SMALL Tools, i.e. shorter cycle times with SMALL Tools.  Let’s proceed
