Expanded Capacity Bar Puller
May 1, 2021
Accudyne Products has introduced its Expanded Capacity bar puller for CNC lathe automation. The new EZ-Puller Expanded Capacity supports larger bar diameters of .093" to 2.00", hex bar capacity of .250" to 1.375" and square bar capacity of .250" to 1.000"
The EZ-Puller is an auto-adjusting bar puller that enables automatic operation of CNC lathes. The auto adjust feature is driven by an "X" value in the pulling subroutine of a lathe program. This value represents the distance the tool needs to move in the X-axis according to the bar diameter being pulled.
The patented design of the EZ-Puller uses a cam and lifter system. Hardened steel pivot arms have an integral cam feature at the top of the arm. Hardened steel grippers advance over the bar stock, compressing internal springs. The springs provide a reactive force that allows the grippers to securely hold the bar stock. This design provides optimal gripping force regardless of bar size or shape.
The EZ-Puller will accommodate an infinite range of sizes within its capacity without adjustment, allowing for multiple pulls. Multiple pulls are used for longer parts that cannot be cost-effectively machined in one chucking. The design of the EZ-Puller also allows for pulling bars with minimal projection in front of the chuck. This characteristic allows the machinist to set up with as little as two gripper serrations (.120") of engagement, which makes for a more rigid set-up.
