Application Background The tools with guide pads are well-suited for the precision machining of special holes. They offer high efficiency and stability while ensuring excellent machining accuracy and surface finish. Their applications span multiple industries, including automotive engine valve guide holes, crankshaft holes, camshaft holes, precision hydraulic valve holes in construction machinery, as well as guide sleeve holes in the mold-making industry. These types of components often encounter the following special conditions during hole reaming: ————————————————————————————————————————- * Deep holes with high length-to-diameter ratios that require tight roundness and cylindricity tolerances\uff1b * Partial holes finishing with high surface quality requirements\uff1b * And stepped or interrupted holes with strict positional tolerance requirements.
