Micro Drilling: Small highly accurate holes are becoming a common requirement across a range of industries and applications. 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 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” (0.1mm) with precision and repeatability in X,Y and Z. Our sheer speed combined with a micro-spray alcohol coolant system produces holes with smooth walls, well defined edges and virtually void of dross or recast.

• Smooth clean walls
• Sharp, well defined edges
• High volume production
• All-in-one micro-drilling, cutting, milling and engraving

In His Own Words
(Datron Customer Speaks Out):

"This project has been a great success, in that we have two machines running identical programs, the cycle times have been reduced drastically and we have also decreased the setup time for other ends of the manufacturing process."

What Is Micro Hole Drilling?
Well, that depends on who your talking to. Some CNC machine manufacturers think that a 1/8" hole is small and tout that their VMC has that capability. But with Datron CNC machines, 0.015" to 0.004" is a walk in the park. Alright, we admit it, that may be an overstatement ... but holes that small are being made each day in a variety of industries with Datron high-speed machine centers. One of the main reasons that Datron machines reign supreme in micro hole drilling is because of our high speed, low force technology (and if you're serious about micro drilling you really need to read the White Paper below). To sum it up, our machines have smaller motors because we cater exclusively to manufacturers who make small parts. Because our machines never run large tools, they simply don't need a hulking motor. The result is that an extremely low force is placed on the tool. That combined with the blazing speed of our 60,000 RPM spindle, a chilled spindle and the superior cooling qualities of our Ethanol-Mist Coolant System (you can read that White Paper too) allows the tool to do its job evacuating chips without causing tool breakage.

Of course, the diameter of a micro hole is only one consideration when undertaking a micro drilling application. Depth of the hole is another considerable challenge ... especially when using small fragile tools that can "walk" and break. This is where runout, positioning accuracy and tight tolerance come into play ... and again, Datron trumps conventional CNC manufacturers. Our VelociRaptor is designed specifically with micro drilling applications in mind and delivers a runout of less than 5 microns, 0.0008" Positioning Accuracy and 0.0004 Repeatability.
