Small, high-precision products are the focus of a new series of horizontal CNC machines that Makino lately introduced. The N2 and N2-5XA are recommended for medical parts and small aluminum parts manufacturing. The machine builder called its new N2 platform is “a high-productivity solution contained in a small package”: installed in a plant or shop, the machines will occupy less than 26 square feet of floor space, including the coolant tank and standard chip management device.

As for performance, Makino said the new series of machines’ 5-axis N2-5XA configuration promotes productivity thanks to five-sided part accessibility and the options it offers for consolidating production work.

“Floor space is often at a premium in medical manufacturing facilities,” explained Makino’s horizontal product manager David Ward. “A traditional 400-mm horizontal machining center can require upwards of 125 square feet of floor space, which is a lot to dedicate to the production of parts that can fit in the palm of your hand.

“The N2 platform delivers a ‘right-sized’ machining solution,” he continued, “built for speed, providing a high-speed spindle, rapid positioning and quick acceleration and deceleration. With the N2-5XA, machine shops and manufacturers can eliminate set-ups and achieve finer surface qualities, making it an ideal solution for many serving the medical market.”

The N2 platform provides a sizable work zone for its compact design. The overall footprint is 45.3 inches wide by 83.7 inches long by 84.6 inches high (1,150 x 2,125 x 2,150 mm.) Despite the weight reduction resulting from this design, these machines maintain a highly rigid structure for enhanced accuracy and reliability.

The four-axis N2 offers a 400-mm high, 400-mm-diameter cylindrical work envelope with X-, Y- and Z-axis travels of 300 x 300 x 230 mm, and a 300-mm diameter direct-drive rotary table.

The five-axis N2-5XA shares the same linear axes and includes twin, trunnion-style direct-drive A and B rotary axes for producing complex, contoured parts. The N2-5XA can hold 300-mm cylindrical workpieces that are up to 270-mm high (ᴓ11.8 x 10.6 inches), with a maximum payload of 66 lbs (30 kg).
