VMC Pneumatic Multiple Clamping Fixture is a custom-designed, air-operated workholding system developed to clamp multiple components simultaneously on a Vertical Machining Center (VMC). By using pneumatic cylinders and precision locators, this fixture significantly reduces loading time, increases spindle utilization, and improves part-to-part consistency.
It is ideal for mass production, batch machining, and automation-ready CNC environments, where productivity, accuracy, and repeatability are critical.
