As part of our March series focusing on jet spindle speeder 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 the ISCAR SPINJET GJET – a Jet Spindle Speeder – designed, developed, and manufactured by Colibri Spindles, ISRAEL.
The GJET can high-speed chamfer with 0.1 – 4.0 mm diameter cutting tools as well as a high-speed slot mill with 0.1 – 3.0 mm cutting tools on steel, stainless steel, non-ferrous metals, and superalloys.

LOMAN, a Slovakian producer, and ISCAR Slovakia Customer has managed to cut their chamfering time by 60%, saving 300 minutes (5 hours) per batch, or in simple terms reducing an 8 1/3 hour process to a 3 1/3 hour process. The SPINJET GJET uses a 6mm diameter SC chamfering endmill – half the size of the standard 12mm indexable 45-degree chamfer endmill. Cutting depth of just 0.2mm is maintained and with an RPM of 5X maximum machine spindle speed, a table feed of 5X is achieved, reaching 15,000 mm/min.
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.
