Dynamic balancing of rotating parts can be extremely tricky when the component being balanced is part of an assembly and the shaft or spindle it mounts to is not available for use during the balancing process. As a result, a specialized dynamic balancing arbor to effectively clamp and hold the rotating part in place during dynamic balancing must be made to simulate the in-situ mounting. These dynamic balancing arbors often cost more than the balanced component. However, for production lots, the cost of the tooling is spread out over some quantity of components, helping to amortize the cost of the custom balancing arbor.
Here at HI-TEK Balancing we are always looking for ways to reduce costs for our customers, especially when some level of customization is required for a particular job. Sometimes the balancing arbor needs to be durable and last for hundreds of cycles, which improves the return-on-investment for the development of the dynamic balancing arbor. However, there are also times when a unique arbor is only needed for just a few uses, or even just one use. In some cases, we can make a “down and dirty” single-use dynamic balancing arbor that works effectively for that specific part and project. Single-use dynamic balancing arbors may sometimes increase the time it takes to balance, but that is usually more than offset by the reduced up-front cost.
In some situations, parts can be balanced arbor-less. This requires soft bearing balancers that can be set up using fixtures and inside diameter (ID) rollers or ID friction blocks, eliminating the need to produce a balancing arbor. It also eliminates the errors created by dynamic balancing arbor fits and arbor runout. This can be a tremendous benefit to the accuracy of the finished balance job. This method works especially well on high-speed turbo parts and parts that have an obstructed mounting bore where an arbor can’t pass through the inside diameter. Another benefit is reduced lead time because no special tooling is required. HI-TEK has acquired multiple balancers with the fixture ID balancing capability.
