Toolholders & Workholding

With the new JUMAT 6S 18-20-18, the engineers at JUNKER have once again expanded their proven portfolio. The simultaneous use of three grinding wheels guarantees maximum quality by utilizing a single clamping set up with an extremely short grinding time, according to the company.

BIG KAISER announces the introduction of the world's reportedly smallest hydraulic chuck for HSK-E25 machine spindles, thus completing its extensive range of BIG KAISER Super Slim hydraulic chucks. The Super Slim type of hydraulic chucks (HDC) are suitable toolholders for precision finishing processes in confined areas with drills, reamers, ball mills, endmills, diamond reamers and grinding tools.

BENZ Inc. has introduced a new product called NanoFix, a modular quick-change system for Swiss lathe live and static tools applications. The BENZ NanoFix modular quick-change system is designed for Swiss-type tooling with a minimum spindle distance of 22 mm and makes it simple to change tools inside the Swiss lathe in as little as 15 seconds.

The ASR1300 high-speed, direct-drive rotary stage from Aerotech Inc. achieves accelerations of up to 8,000 rad/s2 and reaches speeds greater than 1,500 rpm in only 90° of travel, making it suitable for demanding tube-handling applications and high-throughput manufacturing processes. The ASR1300's maximum speed of 3,000 rpm and its acceleration capability result from a full system-level optimization of the torque-to-inertia ratio.

Somma Tool Co. announces the development of a broach toolholder that is reportedly uniquely interchangeable among any style of ER collet chuck. The compact, adjustment-free, offset, rotary broach toolholder will thread to an existing ER (16, 20, 25 and 32) collet chuck and features a built-in 1-degree wobble cutting edge for offset rotary broaching.

Kitagawa NorthTech Inc. provides turnkey, custom engineered workholding services. The company also provides design, engineering, workholding manufacturing, assembly, testing, inspection, documentation, installation and training.

Fives introduces the next product out of its ID/OD line-up to the market. The Landis-Bryant UL2 is an internal high-speed production grinder, ideal for processing bores, faces and contours of bearing rings, valve lifters, gears, universal joint cups and CVJ components, especially suitable for machining workpieces with an external diameter of up to 177 mm.

Klüber Lubrication offers ALTEMP Q NB 50, a white/beige lubricating paste containing a mineral base oil, a barium complex soap and inorganic solid lubricants. ALTEMP Q NB 50 is used as a universal assembly paste, offering benefits especially in friction points with small to minimum motion under high static and dynamic loads.

EXSYS Tool's 90-degree Skiving Drilling and Milling Head not only provides angled drilling and milling capabilities on turning centers, but also enables the machines to perform gear skiving operations. The new head cuts gear patterns faster than conventional gear shaping or broaching methods and generates both internal and external gears with helical profiles, as well as gears close to part shoulders without interference.

The Royal Chuck Stop provides a simple, consistent method for locating short parts in a 3-jaw lathe chuck. The chuck stop enables short parts to project beyond the chuck jaws, providing clearance for facing operations.

MAPAL offers hydraulic chucks specially for tool grinding machines, the HydroChuck Grind-A and the HydroChuck Grind-M. The advantages of MAPAL's hydraulic expansion technology can thus now also be used for tool grinding.

With the SCHUNK TENDO Slim 4ax hydraulic expansion toolholder, it is possible to combine the complete outside geometry of heat shrinking mountings with SCHUNK hydraulic expansion technology. The slim mounting makes it suitable for use in series production, particularly in the automotive industry.
