ARNO FAST CHANGE: The Complete Swiss Solution

by Bernard Martin

The ARNO FAST CHANGE program is designed to meet the demanding needs of Swiss turning operations, from miniature components to larger parts up to 1-5/8" in diameter. As a leader in Swiss quick-change tooling, ARNO offers a comprehensive solution to optimize their processes, reduce downtime, and enhance overall performance.

Expansive Tooling Capabilities
The ARNO FAST CHANGE program is unparalleled in its versatility, with over 50 different gang plates in stock and nearly 200 different types of tools available. This extensive range ensures that ARNO can support a wide array of Swiss turning applications, delivering the precision and reliability that their operations demand.

Innovative Turning Solutions
Their tooling capabilities include options for turning with both positive and negative ISO standard inserts, including C, D, and V geometries. Whether traditional, neutral, or back-turning orientations are required, ARNO FAST CHANGE has the tools to accommodate specific needs, ensuring optimal performance across all turning operations.

Precision Swiss Grooving
ARNO is at the forefront of precision Swiss grooving, offering tools that deliver exceptional accuracy and surface finish. Their Swiss grooving solutions are engineered to meet the tight tolerances and intricate designs typical of Swiss turning, ensuring that every component meets the highest standards of quality.

Multi-Function Groove & Turn Tools
Their multi-function groove and turn tools provide versatility and efficiency in a single tool. With options that include full radius features, these tools enable machinists to perform multiple operations without the need for tool changes, further reducing cycle times and enhancing productivity.

ARNO – ACS Cooling System: The Patented Cooling System For Efficient Parting Off, Grooving And Groove Turning With The SA And SE Grooving Systems.

ACS1 – COOLANT UNDER THE SWARF The coolant (1) is guided directly along the insert seat and exits at the cutting zone. It goes under the swarf and removes it efficiently – so reducing wear effectively and increasing tool life

ACS2 – TWO IS BETTER THAN ONE In addition to the coolant hole at the insert seat (1) there is a second coolant hole underneath the insert tool flank (2). This again increases tool life significantly.

ARNO has engineered the ACS (ARNO Cooling System)—a patented cooling innovation for efficient parting, grooving, and groove-turning with the SA and SE systems. It feeds coolant directly along the insert seat, into the cutting zone, effectively flushing chips away and removing swarf from beneath the insert.

The enhanced ACS2 version adds a second coolant channel that cools the tool flank from underneath, delivering up to a 300% increase in tool life, along with higher cutting speeds and exceptional process reliability. This precision-guided coolant delivery requires no manual adjustment—eliminating setup errors and making the SA and SE systems true productivity powerhouses.

Comprehensive Parting Solutions
ARNO's comprehensive parting program is another cornerstone of the FAST CHANGE system. Featuring the state-of-the-art ACS1 and ACS2 coolant delivery options, their parting tools ensure optimal cooling and chip control, leading to longer tool life and more stable operations. Whether parting miniature components or larger parts, ARNO's parting solutions are designed to meet the challenges of Swiss turning applications.

When it comes to Swiss quick-change tooling, ARNO is leading the way with their FAST CHANGE program. With a vast selection of tools and gang plates, ARNO FAST CHANGE is the complete Swiss solution for your turning operations, helping achieve greater efficiency, precision, and profitability
