At WESTEC 2015, Exsys Tool, Inc. will showcase advanced manufacturing technologies in booth 1919. 

Amongst other products, Exsys will display toolholding innovations that include the Eppinger brand Compacto C3, C4, C5 and C6 base holder system as well as the Preci-Flex modular quick-change tooling system.

Representing modular quick-change tooling at the Exsys booth, the Compacto C3, C4, C5 and C6 base holder enhances the efficiency and productivity of CNC turning machines. When compared with traditional base holder designs, the compact size of Compacto provides more space for machining in tight workspaces, as well as offers improved torque transmission and rigidity for increased tool accuracy. The holder’s polygon shape connection (PSC) is meant to further add to the system’s precision and stability.

A built-in release mechanism on the outer diameter of the base holder’s spindle is designed to provide optimum accessibility. Operators can lock and unlock adapters with a small Allen key for fast tool changes. The automatic ejection feature of the adapters further increases the speed and efficiency of tool exchanges.

Available for bolt-on and VDI-style turrets, the Compacto connection base holder accommodates fixed and rotary tools, including the Preci-Flex system, and accepts all standard PSC adapters. Adapters used in milling applications will now work in turning operations. 

During WESTEC, Exsys will demonstrate its Preci-Flex modular quick-change tooling system, which features a selection of adapters engineered to hold different cutting tool and shank designs. The adapters’ common connecting feature locks into a standard base unit on the machine turret, enabling tool/adapter assemblies to be preset offline then switch in and out of the base unit. Tool positions repeat within +/- 3 µm.

The Preci-Flex conical and flat-face planar interface duplicates the taper of the standard ER collet. This enables ER collets, albeit at lesser repeatability, to be used along with Preci-Flex adapters to mount collets, end mill 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.
