Powerhold Inc. has released JDM Clamps, a flexible clamping system designed to reduce machining centre setup time and steps.
Ideal for machining plates of various shapes and sizes on virtually any machining centre, JDM clamps will allow for quick and accurate setups by less experienced operators, the company says.
“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,” Powerhold says in a release. “Ground in sets, the bases will 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 your workpiece. With the JDM clamps in your tool library, you will easily avoid any collisions with the clamps during your tool path.”
The company adds that the JDM clamps are quickly and accurately positioned on the machine table using positions specified in the NC program. The program will move the machine spindle to the first location. The locator/plunger in the spindle is then slid down and into the clamp base. From there all that’s required is tightening the base to the table and releasing 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.
