Precision cutting Carbide saws with extended application possibilities
For the precision cutting of components and slots, Floyd Automatic Tooling has now introduced the new Nutex Star Mini system that complements the existing line of Nutex saws. The latest addition to this system now incorporates a powerful interface with small shank diameters that helps to extend the application possibilities.
Available with a complete range of saw blade diameters and widths with a comprehensive selection of toolholders, the Nutex Star Mini system from Floyd Automatic is ideal for all machine shops. Precision cutting is assured with a design that delivers precision, repeatability, ease of use and uncompromising tool life, regardless of the material being cut.
Precision cutting is derived from the saw and holder having an identically ground seven-cam interface. This makes the mounting of blades a self-centring proposition that is backlash-free. Furthermore, the saws can be hollow ground or in the known ‘Plus’ design with a side relief angle. The mounting process is rapidly conducted with precision credit to a central screw system that enables fast and easy fitting on the long solid carbide holders. The seven-cam design also ensures that cutting forces are transmitted evenly and tangentially. This enables higher cutting forces to be transmitted through the system, especially when compared with rival systems that offer 2, 3 or 4 driving cams. The benefit for the end-user is twofold with improved precision and process reliability, especially when cutting challenging materials such as aerospace or medical-grade alloys that demand increased torque.
To enhance swarf removal and prolong tool life, Alesa has developed the Nutex Star Mini system with through coolant supply. The internal coolant supply delivers coolant directly to the saw surface via internal cooling channels in the tool shanks. The tool shanks are manufactured from steel or optionally solid carbide to enhance rigidity, performance, vibration dampening and tool life, they are also cylindrically ground to h6 with the option of a Weldon design.
The carbide saws are available uncoated or TiNox coated to cater for a complete range of material types. The TiNox coated blades are available with a 15, 20, 25 or 32 mm diameter with each diameter increment offering an effective cutting width of 0.5, 1, 1.5 and 2 mm with the larger diameter saws also having 2.5 and 3 mm increments. The arbors and saws are available in two star interface types, the type GS10 provides maximum performance and the type GS07 has been developed for maximum groove depth. Also available from 15 to 32 mm diameters, the uncoated saws provide an effective cutting width of 2, 2.1, 2.6, 2.7, 3.1 and 3.2 mm depending upon the chosen saw blade.
The toolholders are available with a steel (Type A6) or solid carbide shank (Type A5) with diameters of 6, 8, 10, and 12 mm with an overall length from 50.3 mm to 111.6 mm. The benefits of this new system include the radial and axial assembly with a very high repeat accuracy that is offered in a large variety of cutting depths.
