Flexible Clamping System

Powerhold Inc. has announced the release of JDM Clamps (patent pending), a flexible clamping system designed to reduce machining center set-up time and steps. "Ideal for machining plates of various shapes and sizes on virtually any machining center, JDM clamps allow for quick and accurate setups by less experienced operators," said a company spokesperson.

The spokesperson continued, "Setting up a machine tool to machine a plate can be cumbersome: indicating the vise or clamps, confirming squareness and flatness, then making sure the tool path will not contact the clamps or vise during machining."

Ground in sets, the bases create a flat Z-axis position and are elevated from the table to aid in chip evacuation. The central shaft of the clamps acts as the part stop, creating a known X and Y position of the workpiece. "With the JDM clamps in your tool library, you will easily avoid any collisions with the clamps during your toolpath," said the spokesperson.

JDM clamps are quickly and accurately positioned on the machine table using positions specified in the NC program. The program moves the machine spindle to the first location. The locator/plunger in the spindle is then slid down and into the clamp base. Tighten the base to the table and release the locator/plunger. Repeat these steps for the location of all the desired clamps.

The modular bases can be moved to a new position for a different workpiece in a matter of minutes. Their shape is designed to make sure they will always be able to reach a T-slot in the machine table. The standard JDM clamps can accommodate workpieces up to 3" thick.

Powerhold is the exclusive builder of JDM Clamps.
