The Micro Mill is a very rigid and precise machine that uses some of the most advanced techniques compared to its competitors. The Y-axis and Z-axis are supported on 2 1/2 inch square steel tubing to provide a very solid feel. The leadscrews are all 1/2-20 unlike a lot of machines of similar size that use 1/4 inch leadscrews. TAIG prefers to provide added mechanical features to allow the mill to be more useful without raising the price. Being an aerospace manufacturer for over 18 years our machinists know the importance of table back-lash compensation and full gib adjustments for wear as employed in the manufacture of the Micro Mill. Basically, the Micro Mill was designed by machinists and built by machinists. Overall working accuracy should exceed .0005 in. All machines are sold with a 14 day refund and a full 2 year factory warranty on all Mill components and accessories.
The Micro Mill has effortless, chatterless, table and millhead movement due to the unique design of oversized gibs, ground ‘Y’ axis steel ways, and a massive carriage assembly. The ground steel ways on the vertical mill head support provides a very rigid Z-axis and makes the Micro Mill ready for CNC upgrade if you desire. Our small Mill is really a scaled down version of a big Mill with manual operation.
This is the machine you don’t have to baby. The Micro Mill is a rugged precision instrument that has plenty of rigidity. It has a life-time ball bearing spindle, coupled with a six speed positive vee belt drive. Spindle speeds in geometric progression from 525-5200 RPM (CR version 1000 – 10000 rpm) provide the power to “HOG” 1/8 inch cuts in mild steel or the speed and precision to “dust” a few tenths (compare that to other mills of similar size on the market, you can’t!).
Other big Mill features include large .001 inch graduations on friction adjustable micrometer dials for the X,Y,& Z axis. Adjustable gibs provide full compensation for X,Y & Z axis wear. The spindle head column can rotate from 0 to 180 degrees to provide for special machining tasks. All this adds up to a BEST VALUE in small Mills.
