From hydraulic valves and spray nozzles to torch tips and gasoline direct injectors, the ability to drill small, precise, repeatable holes is key to the integrity and functioning of a given product. Plus, many of the applications have high volume requirements so drill time ultimately rivals cost and quality in terms of importance. Enter DATRON, with machines that feature a 60,000 RPM spindle that spins micro-drills as small as .004” () with precision and repeatability in X, Y, and Z. Our sheer speed combined with a spray-mist coolant system produces holes with smooth walls, well-defined edges and virtually void of dross or recast.
