Next Generation Tool Grinding and Advanced Gear Hobbing

In Booth N-236909, Star SU, LLC (Hoffman Estates, IL) will feature their new NXT CNC 5-axis tool grinder, designed with big machine capabilities and a small machine footprint. It is built with the purpose of meeting and exceeding what the market demands: a versatile tool grinder with less moving parts and a small footprint, a large grind zone, the ability to run small and large diameter wheels, with easily configurable options, a modular design, and a competitive price point. The NXT fuses the best aspects of their current product line into a next generation machine that offers benefits of smaller size, greater diversity, increased capability, flexibility, durability, and added value.

• Focused design to deliver a maximized grind zone with a small footprint of two meters wide, the smallest footprint to work envelope ratio on the market.
• 28 kW synchronous spindle @ 20,000 rpm.
• Up to 250 mm diameter tools.
• Engineered with the latest in linear and rotary torque motor technology to eliminate backlash, friction effects, and drive vibration.
• FANUC robot automation with 3 mm to 38 mm gripper assembly.
• NUMROTOplus: the best grinding software worldwide.
• Application support available to train operators and manufacture all of your complex tools.
• Designed, manufactured, and serviced in the U.S.

Also on display will be the FFG Werke Modul H 80-200 vertical gear hobbing machine for automotive and job shop applications. The optional automatic high speed part changer is especially engineered for automotive applications, with less than two seconds chip-to-chip time. These machines have been designed for dry cutting applications in particular, although using oil or emulsion is not a problem. Chips are conveyed immediately from the work area by means of steep and smooth stainless steel glad chutes to prevent any build up. The hob head is housed within the tool column, which is tightly fastened to the sturdy machine bed. The CNC tailstock is located on the counter column and cross bar above the hob head, leaving the work area remarkably free for workpiece loading and unloading operations.

Also on display will be a wide variety of gear cutting tools, precision tool re-sharpening services, and advanced coatings from Oerlikon Balzers, including Alcrona Pro and BALANIT® ALTENSA, a high speed coating system that realizes productivity gains and efficiency. Also featured will be Scudding® cutters manufactured to produce gear and spline teeth for reduced cycle times and tool costs.
