Modular quick-change tooling system
The Preci-Flex modular quick-change tooling system features a selection of adapters engineered to hold different cutting tool and shank designs. The adapter’s common connecting feature locks into a standard base unit on the machine turret, enabling tool/adapter assemblies to be preset off-line then quickly switch in and out of the base unit. Tool positions repeat within ±3µm, eliminating the need to re-center, touch off, or make test cuts.
The Preci-Flex conical and flat-face planar interface duplicates the taper of the standard ER collet, enabling ER collets, albeit at lesser repeatability, to be used along with Preci-Flex adapters to mount collets, endmill holders, expanding collet chucks, and shrink fit tooling on a single base holder. Operated at the front face of the turret, the connector provides two tons of clamping force, and its compact design maximizes torque transmission and rigidity, increasing accuracy and productivity.

Six-jaw equalizing chuck
The SJL 6-jaw (2+2+2) equalizing chuck is designed for clamping deformed components while providing the flexibility to hold workpieces as a true 6-jaw self-centering chuck.
Designed with a centrifugal force compensation system, this feature reduces the effects of centrifugal force, allowing for higher speeds and feeds, vastly reducing production time.
The 2+2+2 equalization capability ensures that all six jaws are in contact with the work piece at all times, thus minimizing any deformations or inaccuracies of the component, making it suitable for clamping raw materials.
The 6-jaw self-centering option uses a concentric clamp with all six jaws, allowing it to hold round, machined diameters, and thin-walled workpieces with equal wall thickness.
Available in tongue-and-groove as well as metric serration options, the SJL chuck is available in sizes ranging from 225mm to 400mm.

Automated machining cell
Absolute Machine Tools will demonstrate at IMTS a die-sinker EDM, a machining center, and a robot integrated into an automated machining cell.
A Fanuc M-20iA robot will tend the manufacturing cell consisting of an AccuteX DS-550CM die sinker EDM and a Tongtai TMV-510G machining center. The EDM has an X,Y, Z working capacity of 20" x 16" x 14" (500mm x 400mm x 355mm). The work table size is 32" x 18" (813mm x 457mm). Maximum workpiece size is 47" x 27" x 17" (1,194mm x 686mm x 686mm), and this machine can accommodate workpiece weights up to 2,970 lb. (1345kg). The EDM was designed using finite element analysis (FEA) to ensure high-accuracy machining. Further contributing to its rigidity is a heavily ribbed, high-grade Meehanite casting.
Options for the DS-550 for greater flexibility include a built-in C axis with 360° indexing, an automatic electrode changer, dielectric cooler, and custom tooling package. Customers can perform 3-axis machining in 6 directions, multi-cavity, circular, square, and any angle orbiting, internal/external spherical, and 45° corner machining. Further, the EDM can do 3-axis linear machining, 2-axis arc machining, and offers helical machining electrode compensation.
The TMV-510G machining center in the cell is engineered for high speed, efficient production of precision graphite electrodes and similar items. A fixed column/moving table type machine, it features a high performance 20,000rpm direct-drive spindle that is oil-cooled for thermal stability, and a 20-station, high-speed arm-type automatic tool changer (ATC) that produces tool changes in 0.8 seconds and chip-to-chip times of 1.9 seconds.
With X-Y-Z travels of 20", 14.2", and 11.8" (500mm, 355mm, 295mm) respectively, and a 23.6" x 13.6" (590mm x 340mm) work table area, the machine offers useful work volume in a compact 95" x 55" x 90" (2,375mm x 1,375mm x 2,250mm) footprint that conserves valuable shop floor space.
The cell at IMTS has features specifically for graphite machining. The arm-type ATC keeps tools away from contamination and out of the work zone, and a standard full cover on top of the machine contains dust.
A Donaldson Torit DFO 2-2 1,200cfm dust collector evacuates dust from the machine, and automatic shakers clean the filters and deposit the dust into an easily emptied hopper.
The Fanuc M-20iA performing all the part handling tasks in the cell is a compact robot with a slim wrist and small footprint for operation in tight spaces. It can be mounted on the floor, wall, or ceiling. It has a reach of 71" (1,811mm) and full circular motion.
