It has been shown that pre-cut shims are around four times more cost effective than hand-cut machine shims in time alone. You only need to think about how long it takes to find shim material of the required thickness; mark it; cut it from the sheet stock; deburr and flatten it. How much simpler and quicker it is to select one that’s all ready for use.
When accuracy to hundredths of a millimeter is vital in providing optimum support for machine feet during rotating operations; even the merest fraction of inaccuracy can cause vibration, which may in turn result in breakdowns and expensive machine downtime. The use of precut shims offers consistently accurate positioning, so reducing the likelihood of such disasters.
