Industrial manufacturing of all kinds requires a multi-structured system of planning, building, and troubleshooting. For many industries, this system takes a design/build form of engineering/prototyping, component fabrication/finishing, assembly/finishing, testing/inspection, and packaging/shipping. Each of these operational stages plays a critical role in the full manufacturing process of any industry, but without rigorous testing and inspections, there would be no application of quality control. Without quality control, the other operational stages might as well have never been performed. Schreier Industrial provides practical solutions that give our clients a guidebook and support services for comprehensive quality control through testing and inspections. Our quality control experts offer a range of support for noninvasive and direct testing and inspection, including troubleshooting during the production stages with techniques like dynamic balancing and static balancing.
Both static and dynamic balancing of components and full assemblies are necessary operations for long-term quality and reliability.
Static Balancing: This process is utilized to balance systems that have stationary components with an overall center of gravity on the axis of rotation. With a static balance correctly calibrated, an object can remain perfectly balanced even while motion occurs, such as the switching of positions of a machine component.
An example of static balance is a CNC-controlled robotic arm with a center of gravity at its rotational axis. The arm can rotate on an axis parallel to the ground while the tool/hand remains stationary until it is in place to move and perform a task. When in place, the arm remains stationary while the tool/hand rotates on a separate axis or axes. With both components moving at different times, the whole system remains continually balanced.
Dynamic Balancing: When a component or assembly does not create centrifugal force with rotation, it’s dynamically balanced. An imbalance in rotation creates exponentially growing centrifugal force that pushes a system more and more off balance, quickly leading to a failure or breakdown. Balancing with counterweights that are precisely calibrated allows a rotation to remain dynamically balanced indefinitely if no other external forces are applied.
An example of dynamic balancing is a cylindrical rotating CNC mill with necessary sections on the interior or exterior of the mill system that create an imbalance on one side of the cylinder. Counterweights built into the cylinder create a system that keeps the mill balanced during dynamic movement, preventing the accumulation of centrifugal force when in operation.
Static and dynamic balancing are key operations to support quality and reliable function in with long-term use. To learn more about dynamic balancing and our services, contact Schreier Industrial at (218) 402-0838 today.
