Modular Quick-Change Head System Benefits Various Applications

Iscar USA highlights its new modular quick-change head system for Swiss-type machines intended for turning, grooving, parting and threading applications. The NeoSwiss modular quick-change system features a unique patented clamping mechanism designed for high repeatability. It ensures an accurate cutting-edge position each time an insert is replaced, guaranteeing a high position repeatability of ±0.0008″ for the same head replacement. The rotary wedge mechanism is designed to amplify the clamping force of the head to the shank providing astonishing machining stability. Machining stability helps minimize harmonics which allows the user to run higher parameters and/or extend tool life. Higher parameters and extended tool life equate to higher productivity.

Iscar engineers have designed a neutral shank that can be used for right-hand and left-hand heads. Giving the customer the versatility and ability to switch out insert heads/geometries without having to remove the shank from the machine. The tool holder can also be used for Y-axis machines with dedicated Y-axis-type tools. One advantage of Y-axis-type tools is the main cutting forces are applied in the direction of the shank on the longitudinal axis. This prevents tool bending even under high machining conditions, minimizing vibration and enabling good surface quality.

Iscar’s tools are designed with pinpointed coolant ports from the top and bottom of the tool and 2,000 psi capacity, which guarantees increased tool life and improved chip control. Iscar engineers utilized Computational Fluid Dynamics (CFD) technology to optimize fluid-flow phenomena based on the conservation laws governing fluid motion. The use of additive manufacturing and CFD smooth the flow through the channels to minimize pressure drops and maximize flow rate to the cutting edge. Whereas conventional manufacturing methods have sharp and abrupt corners which can cause interrupted coolant flow and pressure drops.
