Seco Tools Inc. has expanded its versatile MDT (Multi-Directional Turning) system with hundreds of new holders to accommodate a broader range of standard and special machining applications. These new offerings include long-reach holders able to handle up to 8 times the insert width, face machining holders available in Seco's unique Jetstream tooling system in up to 6 times insert width, an expanded internal operations product line, and an array of modular systems including 45-degree holders and long reach machining blades that can achieve up to 5 times the insert width. The MDT system uses a single toolholder and insert for turning, profiling and grooving in both axial and radial directions. The clamping action of the MDT toolholder provides a rigid and stable contact surface. MDT's versatility offers improved productivity through fewer tool changes and machine stops, according to the company. It also simplifies tool handling and stocking requirements by replacing the need for several conventional tools. The MDT system can be used for turning, profiling, grooving and parting off. Suitable applications include turning of parts with many different diameters, complicated profiles and grooves. For complex parts of this type, several standard and special tools can be replaced by one Seco MDT tool. Savings can be achieved through fewer tool changes and reduced stock.
