Electric Spindle System Offers Full Tool Changeability

NSK America’s i-Speed 5 utilizes multiple spindles with independent rpm settings.

NSK America Corp.’s i-Speed5 is an electric, fully tool-changeable, high-speed spindle system which is designed to enable lights-out, high-speed machining. The company says that multiple spindles can be utilized with full tool changeability and independent rpm settings. This .500 hp, 60,000 or 80,000 rpm variable speed system has full integration and communication capabilities to the CNC Control. The i-Speed5 is available in most BT, CT and HSK tapers. A remote unit is available to allow the controller to be mounted inside the machine’s electrical cabinet, utilizing the integral ventilation exhaust tube. The i-Speed5 is said to maintain NSK America’s guarantee of less than 1 micron TIR. A constant clean stop block is utilized to connect the NSK i-Speed5 system to the controller.




Eldorado M75-30T Machine Has Servo-Driven Option

The Eldorado M75-30T from Kays Engineering enables faster part loading and unloading.

The Eldorado M75-30T gundrilling machine from Kays Engineering features an option for a servo-driven fixturing assembly, which allows machine operators to quickly load and unload parts from a more ergonomic position. With the servo-driven option, a Beckhoff servo motor rotates the ballscrew, which provides advance/retract motion for the counter-rotation assembly. The servo-driven option is operated with a toggle switch for faster, more repeatable operation and eliminates repetitive motion for the operator. Safety features include a torque limiter on the servo drive and mechanical limit switches on the slide, which prevent the operator from crashing the fixturing assembly and damaging the machine. The machine includes a counter-rotation fixturing assembly that grips the tailstock end of the workpiece to rotate the workpiece in the opposite direction of the gundrill tool rotation, which improves the accuracy of the drilled hole.




Big Kaiser Drill Suited for Low Cutting Speeds

Big Kaiser’s Nirox drill from Sphinx suited for low rpms.

Big Kaiser Precision Tooling’s Nirox high-performance drill from Sphinx is well-suited for use at low cutting speeds in unstable environments. It’s available in diameters from 0.30 to 3.00 mm and has a geometry with a degressive helix angle equal to 30 degrees at the point. According to the company, the drill is designed for accurate and precise hole location up to 9xD. A modern, TiAlSiN-based coating allows for enhanced chip and coolant evacuation in difficult-to-machine and adhesive materials, such as titanium, Inconel, stainless steel, hardened steel and CoCr alloys.




Rollomatic Adds Sharpening Tool Capability

Rollomatic LaserSmart 510 laser cutting and ablation machine incorporates technologies to sharpen thick-film, diamond-coated carbide tools to keep cutting edges sharp.

Rollomatic added capabilities to allow sharpening of thick-film, diamond-coated carbide tools in its LaserSmart 510 laser cutting and ablation machine. The company says the Rollomatic CNC Laser Cutting Machine LaserSmart incorporates technologies that facilitate probing the surface of the coated cutting edge to detect the exact shape and position. According to the company, the laser cutting process removes just enough diamond coating to make the cutting edge sharp. Only a predetermined amount of the coating (just around the cutting edge) is removed by the laser cutting process. The company states that in‐field tests have demonstrated the tool life can increase significantly with a sharpened thick‐film coated tool compared to conventional diamond-coated cutting tools, and such cutting tools can be a cost‐effective alternative to PCD tools. It is said the new capabilities also provide highly accurate, near‐perfect total indicator runout, fast cycle time, simulation of the tool path after edge detection, and the same machine can laser cut PCD and other super‐hard materials.




Walter’s Boring Bar Features Vibration Damping

Accure∙tec features vibration damping technology for maximum precision.

Walter’s Accure∙tec anti-vibration A3000 boring bar is designed to excel at length/diameter ratios beyond 6 × Dc, which the company says is the point where some conventional steel or solid-carbide boring bars often prove less efficient. The unit is available in lengths of 6, 8 and 10 × Dc, and boring bar diameters of 1.25", 1.50" and 2.00" (32, 40 and 50 mm), with additional sizes and lengths available on request. Capto C6 and C8 spindle connections along with HSK100T connections are also offered as standards. The company says the boring bars feature compact, robust QuadFit precision quick-change exchangeable heads, which boost versatility and decrease downtime. The unit also features internal coolant delivery for optimum chip removal to help achieve superior surface finishes. The  anti-vibration feature is preset at the factory, so the tool is ready for quick application. The tool is also available with both negative and positive inserts, including Tiger Tec silver grade materials for turning productivity. It is said to provide fast and productive counterboring and internal profiling of parts for industries such as aerospace, oil and gas, and general metalworking.
