Jet Spindle Application Insights: Slot Milling

Please note that the image used above is from a separate case study covering several processes, including rough and finish slotting, chamfering and double chamfering, and external finishing, and indicates the time-saving achieved, of between 40% to 66%, for each process when using Colibri Jet Spindles.

As part of our current series focusing on Jet Spindle application insights, we are proud to present these two case studies kindly provided by the Slovakian Office of our Global partner ISCAR.

These case studies at the Slovakian manufacturer LOMAN focus on two critical processes that are successfully covered by ISCAR SPINJET GJET – a Jet Spindle – designed, developed, and manufactured by Colibri Spindles, ISRAEL.  This article focuses on article focuses on Slot Milling and the previous article focused on Chamfering.

As a high-speed slot milling with 0.1-3.0 mm cutting tools on Non-ferrous materials, Steel, Stainless steel, and Superalloys.  For full details of the GJET, adaptor options, technical information, downloads, and capabilities, visit line catalog


In this second case study, LOMAN was looking to improve the processing time for their slotting operation on stainless steel with dimensions  – Ae of 1 mm and Ap of 0.5 mm.  Table feed was improved 9X from 50 mm/min to 450 mm/min and the cutting time per pc was successfully reduced from nearly 16 minutes to just under 2 1/2 minutes, a fantastic 85% time-saving!

As a recommendation, we would suggest to LOMAN to use the HPC Jet for the slotting or alternatively reducing the GJET table feed to 400 mm/min to ensure maximum jet spindle speeder lifetime use.
