April 2016—15 Gleason Corp., call 585-473-1000 or visit This diagram provides a glimpse of the design of the Quik-Flex Plus. Visible are the base unit, activation handle and collet module. medium or large) is mounted to the machine's spindle during a one-time installation. It's easily trued to zero axial and radial runout and permanently locked in place with torque mounting bolts, essentially making it part of the spindle. The base unit is designed both for compactness and to exceed the stiffness requirements for operations that exert signifcant machining forces, such as deburring and chamfering. This strategy is in recognition of the increasingly common practice of integrating these processes into a single machine performing multiple operations. While the base units are designed for Gleason machine spindle specifcations, intermediate plates are available that can match the different bolt patterns found on other spindles. These plates, along with some potential minor modifcations to accommodate different draw rod heights and/or stroke lengths, enable the Quik-Flex Plus to be applied to a range of cylindrical gear production machines. The operator next installs the only other component required—a part-specifc collet module, either expanding (typically for gear bore applications) or contracting (for pinion shaft applications. The operator simply lowers it onto the base unit, ftting the module's retention knob over the base unit's gripper fngers, and rotating the module just enough so that three internal clamp lugs in the base unit are aligned. Finally, the installation is completed by turning the removable activation handle clockwise, which causes internal clamp lugs in the base to engage with the module's retention knob, pulling the module down and precisely centering it with the taper built into the tooling. The gripper fngers pull down to securely lock the module in place and the handle (spring-activated to prevent the handle from being inadvertently left in the machine) is removed. A gear or pinion blank (or line gage) is hand loaded, and then chucked/ de-chucked to fully seat the module. The entire process can take as little as 30 seconds. Because of the widespread use of its predecessor, Quik-Flex Plus has been designed to make it simple and economical for current Quik-Flex users to continue to use their existing modules. A simple adapter base, available in three sizes, can be retroft to an existing module, thus enabling the module to ft onto a new Quik-Flex Plus base.
