RoboDrill EcoPlus Offers Large Tool Capacity and Increased Speed
These high-speed machining centers offer milling, drilling, tapping, deburring and chamfering.
Methods Machine Tools Inc.’s FANUC RoboDrill ecoPlus offers a large 21-tool capacity and increased speed via an optional 24,000-rpm spindle. Two ecoPlus models are available including one with a large X-axis travel and table size.
These high-speed machining centers offer milling, drilling, tapping, deburring and chamfering. Speed and versatility make the machining centers ideal for off-loading bigger, slower machines as well as for performing secondary options, regardless of production volumes.
The ecoPlus D21LiB has a working cube of 19.7″ x 15.7″ x 13″ (500 mm x 400 mm x 330 mm). This machine offers travels of 27.6″ x 15.7″ x 13″ (700 mm x 400 mm x 330 mm). Standard features on both systems include a 14.75 hp (peak), 10,000 rpm or 24,000 rpm direct drive spindle with precision-enhancing thermal compensation, HRV control and a 21-station tool changer. The D21MiB has a table size of 25.6″ x 15.7″ (650 mm x 399 mm) and offers a table size of 33.5″ x 16.1″ (951 mm x 409 mm). Both machining centers have rapid traverses to 1,890 ipm (41 m/min), accelerations/decelerations to 1.5 G, 0.9-second tool changes (tool to tool), rigid tapping to 5,000 rpm; and high-speed reverse tapping (up to 20 times faster than infeed). Each are equipped with a FANUC 31i-B Nano CNC with simultaneous three-axis control.
Options include high-speed indexers, a fourth axis, a signal lamp and robotic automation packages from Methods.
Because endworking is often considered only as a preliminary step for shaft work typical of the automotive industry, potential productivity gains are being passed by. Newer technology has enabled these machines to handle far more applications.
Micro-milling can be a companion process to turning-based production machining. This article looks at some of the technologies that go into a micro-milling machine and why they are important to successful operation.
Introduced to the turn-mill machine tool design in about 1996, the Y axis was first used on a single-spindle, mill-turn lathe with a subspindle. The idea of a Y axis on a CNC originated from the quality limitation of polar interpolation and the difficulty in programming, not from electronic advances in controls or servomotor technology as one might commonly think.
